MLRA notes
Major Land Resource Area (MLRA): 155X–Southern Florida Flatwoods
This MLRA makes up about 19,973 square miles (51,731 square kilometers) and is entirely in Florida. It stretches across the mid-section of the State, from the Gulf of America to the Atlantic Ocean, and north and south from the Everglades (MLRA 156A) to Jacksonville. This MLRA consists of a young sandy marine plain of Pleistocene age that is underlain by Tertiary-age limestone bedrock. The terrain is nearly level to gently sloping with large areas of swamp and marsh. Sinkholes affect land use and management.
The landscape consists of nearly level to gently sloping marine terraces that have large areas of wetlands and marshes. Streams and lakes are common. Lowlying wet areas are flat with some hummocks that rise 3 feet (1 meter) above the general level of the landscape. Coastal areas consist of low beach ridges and dunes that rise 6 to 10 feet (2 to 3 meters) above the lower inland areas. Elevation ranges from sea level to less than 196 feet (60 meters), increasing gradually from the coast to inland areas.
This MLRA is underlain by sediments of the Quaternary Period (present to 2.58 million years ago) which overlie Neogene (2.53 to 23.03 million years ago) and Paleogene (23.03 to 66 million years ago) formations, including those of the Hawthorn Group. The older rocks are exposed in the north-central part of this area. The Quaternary sediments are largely undifferentiated marine deposits consisting of fine to coarse sands that are poorly to moderately sorted with variable admixtures of clay and organic material. Undifferentiated Holocene (present to 0.0117 million years ago) sediments, which include quartz sands, marls, organic material, and minor carbonate sands and mud, are in the northeast part of this MLRA. The sediments may also include freshwater gastropods. Near the southeastern coastline, the Anastasia Formation and Miami Limestone are exposed. The Anastasia Formation is made up of a variably lithified coquina of shells and sands and unlithified fossiliferous sand. The Miami Limestone is white to light gray, variably fossiliferous, oolitic and pelletal with variable percentages of quartz sand, ranging from sandy limestone to calcareous quartz sand (Scott, 1993a, 1993b; Duncan, 1993a, 1993b). Quaternary beach ridge and dune sediments, which are mapped based on topographic expression, occur throughout the MLRA, becoming more abundant toward the coast.
The average annual precipitation is 38 to 61 inches (973 to 1,559 millimeters). About 60 percent of the precipitation occurs from June through September. Most of the rainfall occurs during moderate-intensity, tropical storms that produce large amounts of rain from late spring through early autumn. Late autumn and winter are relatively dry. The average annual temperature is 69 to 76 degrees F (21 to 24 degrees C). The freeze-free period averages 335 days and ranges from 300 to 365 days.
The dominant soil orders are Alfisols, Entisols, and Spodosols. The soils in the area dominantly have a hyperthermic temperature regime, an aquic moisture regime, and siliceous mineralogy. They generally are deep or very deep; poorly drained, very poorly drained, or somewhat poorly drained; and sandy or loamy, or both. Anthroportic soils throughout the area are a result of cut-and-fill activities associated with construction and urbanization.
This area supports flatwood forest vegetation. Slash pine, longleaf pine, loblolly pine, cabbage palm, bald cypress, laurel oak, water oak, and live oak are the main species. Saw palmetto, wax myrtle, gallberry, and grasses such as bluestems, threeawns, maidencane, and wiregrasses characterize the understory. Along the coastline and around the city of Orlando, this MLRA has been heavily urbanized. However, a significant acreage remains in agriculture for the production of citrus, specialty crops, and cattle (fig. 155-2). Surface water runoff from agriculture and urbanization are carefully monitored to help mitigate sinkhole development.
The major soil resource concerns are wind erosion, maintenance of the content of organic matter and productivity of the soils, and management of soil moisture. Conservation practices on cropland generally include conservation crop rotations, cover crops, irrigation water management (including micro irrigation systems), nutrient management, and pest management. Conservation practices on pasture and rangeland generally include prescribed grazing, brush management, pest management, prescribed burning, and watering facilities. Conservation practices on forestland generally include forest stand improvement, forest site preparation, prescribed burning, firebreaks, establishment of trees and shrubs, pest management, and management of upland wildlife habitat.Classification relationships
All portions of the geographical range of this site falls under the following ecological / land classifications including:

This ecological site is associated with very poorly drained sandy soils on floodplains in central and south Florida. These sites are frequently flooded for brief to very long durations and will usually correlate with seasonal rainfall patterns during the summer months. Soils will range from 20 inches to 40 inches of fine sand or sand over a loamy subsoil (argillic horizon). The organic matter content of the surface layer is dominantly low to high. The presence of these subsurface horizons at the given depths will attribute to specific production values in managed states compared to soils with similar horizons at different depths on similar landforms.
Dominant vegetation within this site correlates with Florida Natural Area Inventory communities "Floodplain Marsh" and "Floodplain Swamp". These sites are adapted for harsh environmental conditions including flooding for extensive periods of time, resulting in highly anaerobic conditions. Extensive loss of natural habitat can be attributed to anthropogenic activities of installing water control structures to drain water for urban and agricultural uses.
Small variations in hydrology and topography will drive the distribution of the two dominant vegetative states and their corresponding communities in this site and currently cannot be mapped separately within SSURGO resolution. This may be split following future projects addressing floodplain soil map units, but for now we must consider non-forested communities and forested communities as their own naturalized states.Associated sites

This ecological site and its associated plant communities occur in floodplains on marine terraces throughout central and south Florida. These are vast stretches of nearly level land on slopes from 0 to 2%. This site will often occur in the lowest portion of the landscape along riverine systems and will be subject to hydroperiods that will result in long to very long duration flooding conditions. Variation in microtopography is common on this site, resulting in a matrix of concave - linear areas in a dominantly linear - linear landscape.

">Influencing water features
These wetlands are primarily influenced by over-bank flow from connected riverine systems. Rainfall and runoff from upland communities as well as groundwater flow into the riverine system will attribute to the naturally seasonal high water table. Water will move laterally as a massive, slow moving, overland sheet water flow following the low landscape, resulting in minimal or a complete lack of alluvial deposits.<br />
<br />
There is usually a delay between the onset of rainfall and the peak river flows that causes the wetland inundation. Seasonal patterns of water flow in floodplain wetlands occur primarily during the mid-summer months into the early winter months (July through December) and is attributed to rainfall during summer storms. This will be reflected by above ground surface water conditions during these months followed by a seasonal high-water table of 0 to 18 inches during the mid- to late-winter months into early summer (January through June). Events often associated with tropical storms, hurricanes, drought, or El Niño / La Niña climate patterns can shift the seasonal water inputs longer or shorter than the average wet seasons.Wetland description

Soil features
These soils form in sandy and loamy marine deposits and are typically very deep. Typical soils will range from 20 inches to 40 inches of fine sand or sand over a loamy subsoil. Diagnostic subsurface horizons may include an argillic horizon between 20 inches to 40 inches. A mucky surface texture modifier may often be seen. There are no restrictive features associated with this site.
There is a diverse set of soil taxa associated with this site and is most influenced by flooding conditions on sandy over loamy floodplain soils. Soils include Arenic Endoaqualfs (Isles, Felda), Arenic Glossaqualfs (Riviera, Pineda), Arenic Argiaquolls (Gentry, Floridana), and Typic Argiaquolls (Manatee).Table 5. Representative soil features

Water Table Dynamics
Due to the flat topography of this MLRA, minimal gradients, high precipitation amounts, and seasonal temperature changes, there are often extreme fluctuations of the water table between summer and winter months.
As water accumulates in the adjacent systems it needs to reach maximum water holding capacity before overflowing into the floodplain communities. Due to the seasonal change of water inputs in these communities, soil conditions will often oscillate between anaerobic and aerobic conditions and may allow for a layer of decomposed organic material to accumulate on the surface. Water will be temporarily held in these wetlands during the summer months and then slowly released into the groundwater aquifer (Florida Aquifer System) or recede via evaporation or evapotranspiration during the winter months (Haag et. al, 2010).
Changes in wetland community distributions are dependent on local environmental conditions such as cyclical changes in precipitation and community disturbances such as fire suppression and anthropogenic alterations to surrounding habitats (ditching, drawdown of water table). Drier conditions may contribute to an increase in conversion of marsh wetlands to shrub-scrub or forested wetland communities.
Plant Community Dynamics
Changes in vegetation in these communities are often distributed via slight changes in hydroperiod that cannot be met with our current scale of mapping, resulting in two naturalized states of forested and non-forested wetland systems. Along the wetland edges, in the upland transition zone, more mesic species and ecological communities of poorly drained sites such as hydric savannas and hydric forests may occur.
Seasonal flooding is the main ecological driver for both forested and non-forested states. This extended hydroperiods is necessary to maintain the plant compositions and provide oxygen and nutrient inputs. The understories of these communities will vary seasonally, and will often be inundated to various depths in the summer months and support floating aquatic emergent and persistent emergent herbaceous species. In the winter months when water is receding or absent the understory will often support non-persistent emergent herbaceous and hydrophytic grasses. Seeding of cypress seeds and other hardwoods in dry years (where hydrology is not altered) in a floodplain marsh may allow the introduction and establishment of these trees, creating a closed canopy floodplain swamp (Titus, 1991; Wetzel et. al, 2001). Extended loss of hydroperiods within non-forested systems may allow for the encroachment of shrubby woody species in the understory. In forested systems, a loss of hydroperiod may also result in the increase of shrubby woody species as well as other hardwood trees such as bays, gums, elms, oaks, and maples, creating a mixed hardwood forest (Titus, 1990).
Ecotones within the floodplain on slightly higher sandy levees and terraces may support deciduous closed canopy forests, known locally as bottomland forests (FNAI, 2010). These will often differ from the mixed hardwood swamps by the lack of organic accumulation and higher relief on sandy soils on a scale unmappable at our current resolution. While not as prone to a prolonged inundated growing season as floodplain swamps, it is still influenced by high-water tables and peak seasonal flooding. Variations in seedling establishment are often caused not only by flooding regimes, but also by windthrows and treefall gaps that allow for the establishment of shade intolerant species. This community may be separated out into its own unique site concept following future ecological site verification projects and soil map unit update projects.
Disturbances
Next to seasonal flooding, fire regimes are the second most important ecological process which influence this site, especially in non-forested wetland communities. Fire regimes will be specific to each individual community and will often enter from pyrogenic upland habitats and extinguish themselves. Natural fires were principally caused by lightning but have since been replaced by prescribed burning due to the fragmentation of these habitats from roads and other anthropogenic features. Fire is used to prevent woody encroachment into freshwater marshes and to promote flowering phenology of certain species. Fire in swamp communities is less common due the highly shaded ground conditions. During years when swamps are dry, peat fires may burn the roots of cypress trees, killing the plants and seeds and converting these areas to scrub - shrub wetlands and areas favoring replacement by willows and subsequent hardwoods (Coladonato, 1992). If the root systems are not killed following fire, cypress and other hardwoods will often sprout from the stumps when top killed. Without fire over extensive periods of time, bays and other hardwoods may increase in density and cause more rapid peat accumulation.
Introduction of non-native animals such as feral hogs (Sus scrofa) may cause extensive uprooting in these systems and lead to changes in localized hydroperiods and introduction of invasive plant species.
Anthropogenic Influences
Historical channelization of riverine systems for navigation and flood control purposes may have altered these communities to create better drained sites and sites to be utilized for altered management such as pastures and agriculture (Milleson et. al, 1980). Wetlands are currently protected at the Federal, State, and County level in Florida under various passed bills. Many wetlands have been converted back to their reference communities through the Wetlands Reserve Program (WRP) with assistance from Florida NRCS. The following altered states shown in the state and transition model should be used as guidance when creating land management plans on converted wetlands to prevent further loss to soil resources. Many of these wetlands are found as wildlife habitat and corridors surrounding converted land and will require specific management plans to protect and enhance ecological integrity of the remaining systems.State and transition model

Floodplain Concept STM Key
I. Natural Stable Reference States- the ecological state that is most resistant to change, offers the most options to achieve management objectives, and reflects a defined “natural” disturbance regime.A. Non-Forested Wetlands - wetlands dominated by erect, rooted, herbaceous (non-woody) vegetation during most of the year and are often called marsh communities.1 Frequently flooded wetland communities occurring within river floodplains dominated by herbaceous vegetation. Trees are sparse to absent. Flat topography and slow drainage create prolonged inundation periods caused by flooding conditions of adjacent rivers and streams, as well as inputs from overland flow and rainfall.2 This community describes a non-forested wetland that is undergoing environmental change due to some type of disturbance. These will be dense, low-growing woody vegetation that are less than 20 feet (6 meters) tall.B. Forested Wetlands - wetlands dominated by hydrophytic trees (Cypress / Tupelo) and are often called swamp communities.1 This community describes a forested wetland that is a closed canopy forest of hydrophytic trees dominated by a pure stand of cypress or tupelo.2 This community describes a deciduous, or mixed deciduous/ evergreen, closed canopy forest on terraces and levees within floodplains. It is unique from the successional stage of cypress- tupelo floodplain swamps (mixed hardwood floodplain swamp) by its location intermediate between lower floodplain swamps and marshes, and upland communities.3 This community describes the successional state of a cypress-tupelo floodplain swamp. This community consists of a closed overstory of cypress-tupelo and hardwood species such as bays, gums, elms, oaks, titi, and maple.II. Alternative Ecological States- one of several potential states of an ES that is functionally different from the reference state in terms of important ecological processes, kinds and amounts of ecosystem services, and management requirements.A. Rangeland - introduced grazing species on lands on which the indigenous vegetation is predominately grasses, grass-like plants, forbs, and possibly shrubs or dispersed trees. Existing plant communities can include both native and introduced plants.1 This phase represents the representative phase of the natural community that has been converted to rangeland in excellent conditions2 This phase represent the succession of rangeland in excellent condition to poor or fair conditionsB. Managed Grassland / Pastureland - vegetation cover comprised primarily of introduced or enhanced native forage species that is used for livestock grazing. Pasture vegetation can consist of grasses, legumes, other forbs, shrubs or a mixture. The majority of these forages are introduced, having originally come from areas in other states or continents.1 This phase represents the natural community that has been converted to managed grassland / pastures in excellent conditions found adaptive to the natural seasonal high-water table representative of this community.2 This phase represents the natural community that has been converted to managed grassland / pastures in excellent conditions found in drained and cultivated areas of this natural community.3 This phase represent the succession of pastureland and/or open grassland to unmanaged conditionsC. Silviculture - controlling the establishment, growth, composition, health, and quality of forests and woodlands.1 This phase describes the growth, management and harvesting of cypress (Taxodium spp) and tupelo (Nyssa spp.) species for various uses.D. Reclaimed / Restored Wetlands - non-forested and forested wetland communities which have undergone or currently undergoing transition from an altered state (agriculture field, pasture, forestry land, urban areas) to a restored natural community.1 This community described a reclaimed or restored non-forested floodplain wetland community.2 This community described a reclaimed or restored forested floodplain wetland community.E. Invaded State - consists of Florida Department of Agriculture and Consumer Services (FDACS) Non-Native Category 1 Species list.1 This phase describes the introduction and establishment of invasive species common to this ecological site; Brazilian peppertree (Schinus terebinthifolia), Torpedo grass (Panicum repens), water hyacinth (Eichhornia crassipes), and melaleuca (Melaleuca quinquenervia).F. Human Altered and Human Transported Areas - areas that were intentionally and substantially modified by humans for an intended purpose, commonly for terraced agriculture, building support, mining, transportation, and commerce. The alteration is of sufficient magnitude to result in the introduction of a new parent material (human-transported material) or a profound change in the previously existing parent material (human-altered material).1 Areas developed for human use. These include a variety of land uses, e.g., inner city or urban core, industrial and residential areas, cemeteries, parks, and other open spaces; the overall function which may benefit the quality of human life2 This community consists of the creation and channelization of anthropogenic waterways for water control use and floodwater protection. Primary purposes of these systems are to transport floodwaters and reduce flood damage to upland communities in the area.3 This community is often seen in conjunction with the creation and channelization of anthropogenic waterways as deposited spoil materials creating artificial impoundment areas.State 1
Non - Forested Wetlands

This state is described as wetlands dominated by erect, rooted, herbaceous (non-woody) vegetation during most of the year and are often called marsh communities.
Community 1.1
Floodplain MarshFloodplain marshes are frequently flooded wetland communities occurring within river floodplains dominated by herbaceous vegetation. Trees are sparse to absent. Flat topography and slow drainage create prolonged inundation periods caused by flooding conditions of adjacent rivers and streams, as well as inputs from overland flow and rainfall.
This community correlates with the Florida Natural Area Inventory community "Floodplain Marsh" (FNAI, 2010).Forest overstory.Occasional cabbage palm (Sabal palmetto) and other flood tolerant trees may be widely scattered in these systems, and will often increase in density along the ecotones of upland communities.
Forest understory. Sand cordgrass (Spartina bakeri), sawgrass (Cladium jamaicense), and maidencane (Panicum hemitomon) are common dominants, but various other herbs may be found distributed along a hydrologic gradient. <br /> <br /> Broadleaf emergents and floating plants, particularly bulltongue arrowhead (Sagittaria lancifolia), bladderworts (Utricularia spp.), pickerelweed (Pontederia cordata), yellow pondlily (Nuphar advena) occupy the deepest, most frequently flooded sites, and mixed herbaceous stands are found in the somewhat higher portions of the marsh.<br /> <br /> The highest part of the marsh is often a drier, wet prairie-like zone with a large diversity of graminoids and forbs. Additional herbs can include dotted smartweed (Polygonum punctatum), bulrushes (Scirpus spp.), common reed (Phragmites australis), tickseeds (Coreopsis spp.), primrosewillows (Ludwigia spp.), fimbries (Fimbristylis spp.), spikerushes (Eleocharis spp.), flatsedges (Cyperus spp.), many flower marshpennywort (Hydrocotyle umbellata), soft rush (Juncus effusus ssp. solutus), grassleaf rush (Juncus marginatus), beaksedges (Rhynchospora spp.), rosy camphorweed (Pluchea rosea), lemon bacopa (Bacopa caroliniana), spadeleaf (Centella asiatica), swamp rosemallow (Hibiscus grandiflorus), saltmarsh morning glory (Ipomoea sagittata), cattails (Typha spp.), southern cutgrass (Leersia hexandra), and climbing hempvine (Mikania scandens).

Shrub - Scrub WetlandThese wetlands are the result of the drawdown of the water table of a non-forested wetland that no longer reflects it natural hydroperiod. Deposition of seeds from aerial dispersion from birds or from flood pulses will provide the system with viable variable seedbank. These shrubs will consist of both true shrubs that never attain a greater height, and young trees of other species that may never obtain their maximum height due to the harsh environmental conditions. There will be no plants in the overstory, with a midcanopy of shrubs and young trees, and a dense to sparse understory of grasses and herbaceous species typical of the reference community it transitioned from.
Forest understory. Woody shrubs will be low-growing and densely packed, shading out the reference community understory species. These trees and shrubs will be less than 20 feet (6 meters) in height. Common species which will encroach and become established include wax myrtle (Morella cerifera), coastal plain willow (Salix caroliniana), cypress (Taxodium), common buttonbush (Cephalanthus occidentalis), fetterbush (Lyonia lucida), and cabbage palm (Sabal palmetto). Sparse reference community understory grasses and sedges may be present.

Pathway 1.1a
Community 1.1 to 1.2This transition is driven by decreases in the long term hydroperiod. This change of hydrology will allow for the growth and establishment of woody species that would not have been able to colonize due to the flooding conditions.
Pathway 1.2a
Community 1.2 to 1.1This transition is driven by the removal of undesirable species and reestablishment of natural management strategies. Removal of undesirable hardwood species may be necessary to increase light availability to herbaceous groundcover and should be removed carefully to prevent disturbance to the surrounding community. Restoration and reestablishment of natural management strategies should include restoring the seasonal high-water table and flooding conditions of the reference community. Introduction or reintroduction of fire into the system may serve to supplement the effects flooding conditions would have on the reference community.
State 2
Forested Wetlands
Figure 9. Forested Floodplain Wetland immediately adjacent to a flooded waterbody.
This state is described as wetlands dominated by trees and are often called swamp communities. The most common trees found in forested wetlands are cypress and tupelo, as well as several hardwoods such as bays, gums, elms, oaks, titi, and maples. Individual community composition and structure is dependent on patterns of seasonal flooding and small differences in microtopography. Arboreal epiphytes are abundant in forested wetlands and can be found growing on tree trunks and limbs, obtaining moisture and nutrients from condensation and rainfall. Buttressed trunks and modified root systems such as cypress knees are adaptations to prolonged hydroperiods and are characteristic of these communities, and may often create micro-habitats supporting species less adapted to prolong hydroperiods. Mosses and lichens growing on the bark of these species will serve as an indicator to seasonal inundation levels by growing to the water line.
Community 2.1
Cypress- Tupelo Floodplain SwampThis community describes a forested wetland that is a closed canopy forest of hydrophytic trees dominated by a stand of cypress or tupelo. These will often occur on frequently flooded hydric sandy soils adjacent to stream and river channels and on oxbows. These will range in size from narrow strips along primary and secondary streams to expansive stands along large rivers.
This community correlates to the Florida Natural Area Inventory community "Floodplain Swamp" (FNAI, 2010).Forest overstory.The canopy is sometimes a pure stand of bald cypress (Taxodium distichum), but more commonly bald cypress shares dominance with one or more of the following tupelo species: water tupelo (Nyssa aquatica) or swamp tupelo (N. sylvatica var. biflora). Other canopy trees capable of withstanding frequent inundation may be present but rarely dominant, including water hickory (Carya aquatica), overcup oak (Quercus lyrata), red maple (Acer rubrum), green ash (Fraxinus pennsylvanica), American elm (Ulmus americana), and swamp laurel oak (Q. laurifolia). Pond cypress (T. ascendens) is sometimes present in backswamps and depressions of the more hydrologically isolated areas of the floodplain. Arboreal epiphytes such as airplants (Tillsandia spp.), and mosses and lichens will be present on trunks and limbs of overstory trees to the upper limit of the water lines present on the trees.
Forest understory. Shrubs and smaller trees such as Carolina ash (Fraxinus caroliniana), planer tree (Planera aquatica), black willow (Salix nigra), titi (Cyrilla racemiflora), Virginia willow (Itea virginica), common buttonbush (Cephalanthus occidentalis), cabbage palm (Sabal palmetto), and dahoon (Ilex cassine) may be present.<br /> <br /> A groundcover of flood tolerant ferns, grasses, and herbs are found in some floodplain swamps primarily dominant during the dry season when there is little to no surface water. Herbaceous species include lizard’s tail (Saururus cernuus), false nettle (Boehmeria cylindrica), creeping primrosewillow (Ludwigia repens), savannah panicum (Phanopyrum gymnocarpon), royal fern (Osmunda regalis var. spectabilis), dotted smartweed (Polygonum punctatum), climbing aster (Symphyotrichum carolinianum), and string lily (Crinum americanum). Grasses may include maidencane (Panicum hemitomon), blue maidencane (Amphicarpum muehlenbergianum) and sawgrass (Cladium mariscus ssp. jamaicense). These species tend to decrease in cover during the wet season and become replaced with surface water which may support a mixture of floating aquatics such as duckweeds (Lemna spp.) and Florida mudmidget (Wolffiella gladiata).

Community 2.2
Mixed Hardwoods Floodplain SwampThis community consists of a closed overstory of cypress-tupelo and hardwood species such as bays, gums, elms, oaks, titi, and maple. Mixed hardwood swamps rely on the absence of fire for very long periods of time to allow for the accumulation of surficial organic matter which will raise the ground surface, decreasing the amount of standing water present with less water-level fluctuation. This community can often be identified by a higher density of these hardwood species in the overstory and increased peat accumulation. It may be common to see high seedling densities of these hardwood species, particularly bays, and may have an increased density of sphagnum moss beds due to high soil saturation but less frequent inundation. These communities are often relatively small in size, and may be seen as isolated hummocks within a cypress swamp community. Under a natural disturbance regime in the reference communities, successional change is thought to be rare since these swamps become seasonally dry and would burn periodically, killing these hardwoods and preventing organic matter build up. Increases in anthropogenic activity in surrounding areas by drainage or protection from fire may speed up these processes. This community may be a result of logging influences on natural cypress swamps, as increased light availability and logging slash may provide suitable habitat for the growth of these hardwoods as well as the natural regeneration of cypress.

State 3
Grazed RangelandRangelands are described as lands on which the indigenous vegetation is predominately grasses, grass-like plants, forbs, and possibly shrubs or dispersed trees. Existing plant communities can include both native and introduced plants. Primary export from Florida ranges are cattle and have been present in the state since their first introduction by Spanish explorers in 1521. Native forage production is very good with proper management in this community, with only a slight effect on the community. Proper management will often result in an increase of grasses and reduction of shrubs while also maintaining proper fire intervals. Rangelands provide a diversity of ecosystems and also provide a diverse and significant production of economic benefits and ecosystem goods and services. Livestock production along with sustainable wildlife populations provide for the major direct economic benefits, but also tourism, recreational uses, minerals/energy production, renewable energy, and other natural resource uses can be very significant. Vital ecosystem contributions include clean water, clean air, fish/wildlife habitat, as well as intangible considerations such as historical, cultural, aesthetic and spiritual values. It is strongly advised that consultation with State Resource Conservationist and District Conservationists at local NRCS Service Centers be sought when assistance is needed in developing management recommendations or prescribed grazing practices.
Rangeland in this ecological site is described for the Non-Forested Wetland state, not for the Forested Wetland state. Non-Forested Wetland communities have higher percentages of forgeable species due to the natural community composition and structure and have commonly been used as rangeland since European settlement. Forested Wetlands may have some forgeable species in the understory but are not utilized as rangeland. The major limitation to grazing species in these communities are extended hydroperiods represented by flooded conditions.Community 3.1
Maidencane – Cutgrass- Toothache Grass – Blue Maidencane (RSG010 - Excellent)This phase represents the representative phase of the natural community that has been converted to rangeland in excellent conditions. This phase will have an open canopy with an open or shrubby understory dependent on the reference state. In excellent condition maidencane (Panicum hemitomon), cutgrass (Zizaniopsis miliacea), toothache grass (Ctenium floridanum), and blue maidencane (Amphicarpum muhlenbergianum) species will provide the greatest portion of the forage production. These wetlands are often grazed in the winter months when there is little to no standing water in these communities and forage species will provide the greatest nutritional values. This community correlates with the Florida Legacy Range Site 155XY010FL – “Freshwater Marshes and Ponds”.
Resilience management. Proper range management of rotational grazing, burning, and hydrologic management may improve the condition of a range. Rotation of cattle on range is important mostly for the maintenance of the range resource to ensure areas are not overgrazed and ecological integrity is protected. Rotational burning is the oldest and perhaps the least expensive method to improve forage quality. The practice consists of burning different portions of the range at different times during the fall and winter and permitting cows to move to new burns. Burning should be consistent with natural fire return intervals of the community being grazed to prevent a shift in species composition. Burning and grazing can lead to range deterioration if not used properly. Forages must be allowed to regrow (no grazing) to restore vigor, and when cattle are allowed to graze regrowth, care must be taken to assure that these burned areas are not overgrazed, especially in May and June. Prescribed fire for range improvement will also benefit undesirable shrub control and improve wildlife habitat as well as hazardous fuel reduction. Rotation is essential to prevent overgrazing from cattle species in these freshwater marshes and prairies. Marshes that are subject to extensive grazing and cattle trampling will create open spaces devoid of native vegetation, changing competitive dynamics between plant species leading to shifts in wetland plant communities. These areas are highly susceptible to invasion of weedy pasture grasses, especially where the surround community has been converted to pasture, with the wetland left as wildlife habitat and watering holes. Invasive pasture grasses may include carpet grass, centipede grass, bahiagrass, and the invasive West Indian Marsh Grass. One of the greatest limiting factor to grazing in these communities is the seasonal high-water tables, which may result in varying depths of ponding conditions during the summer months. Drainage or drawdown of the water table of these communities may lead to shifts in species composition and should be carefully managed.

Typha spp – Pickerelweed – Torpedo grass- Threeawns (RSG010 – Poor to Fair)This phase represents the transition of rangeland in excellent condition to poor or fair conditions. Duration of this phase is dependent on former and future management, use, and impacts. This poor to fair condition phase will most often consist of cattail species (Typha spp), pickerelweed (Pontederia cordata), torpedo grass (Panicum repens) and a variety of threeawns (Aristida spp.). This phase often transitions due to poor management, including overstocking and overgrazing, as well as mismanagement of the natural habitat. Other undesirable species may be present in this community that have not been mentioned,

State 4
Managed Grassland / PasturelandPasture is a land use type having vegetation cover comprised primarily of introduced or enhanced native forage species that is used for livestock grazing. Pasture vegetation can consist of grasses, legumes, other forbs, shrubs or a mixture. The majority of these forages are introduced, having originally come from areas in other states or continents. Most are now naturalized and are vital components of pasture based grazing systems. Pasture lands provide many benefits other than forage for livestock. Wildlife use pasture as shelter and for food sources. Well managed pasture captures rainwater that is slowly infiltrated into the soil which helps recharge groundwater. Many small pasture livestock operations are near urban areas providing vistas for everyone to enjoy. It is especially important as livestock managers continues to experience extraordinarily high fuel and other input costs. Overgrazed pastures can lead to soil compaction and numerous bare spots, which may then become focal points of accelerated erosion and colonization sites of undesirable plants or weeds. It is strongly advised that consultation with State Resource Conservationist and District Conservationists at local NRCS Service Centers be sought when assistance is needed in developing management recommendations or prescribed grazing practices. This grassland / pastureland state correlates with the 2013 Florida Forage Suitability Group G155XB245FL (Sandy over Loamy Soils on Stream Terraces, Flood Plains, or in Depressions). These communities are often found behind anthropogenic levees with canals running through to divert waterflow during the wet season. If the reference communities are excessively drained and then converted to grasslands or pasture, then forage species and values correlating with the 2013 Forage Suitability Group G155XY241FL (Sandy over Loamy Soils on Flats on Mesic or Hydric Lowlands) should be utilized.

Limpograss – Maidencane – Blue Maidencane (FSG245)This community phase represent commonly planted forage species on pasturelands, haylands, and open grasslands found adaptive to the natural seasonal high-water table representative of this community. The suite of plants established on any given site may vary considerably depending upon purpose, management goals, and usage (e.g., horses vs. cattle). Most systems include a mixture of grasses and legumes that provide forage throughout the growing season. Warm season perennial forage species often include limpograss (Hemarthria altissima), maidencane (Panicum hemitomon), and blue maidencane (Amphicarpum muhlenbergianum). Warm season annual forage species often include Japanese millet (Echinochloa esculenta) and aeschynomene (Aeschynomene americana). Several additional plants and/or species combinations may be present depending on the objectives and management approaches of the land manager/owner.
Resilience management. Unless previously drained, soils in this community have very few forage species adapted to their seasonal high-water table (1 to 2 feet above the soil surface). If previously drained see forage list and discussion with Community 4.2.

Bahiagrass – Bermudagrass – Bluestem (FSG241)This community phase represent commonly planted forage species on pasturelands, haylands, and open grasslands found in drained areas of this natural community. The suite of plants established on any given site may vary considerably depending upon purpose, management goals, and usage (e.g., horses vs. cattle). Most systems include a mixture of grasses and legumes that provide forage throughout the growing season. Warm season perennial forage species often include bahiagrass (Paspalum notatum), bermudagrass (Cynodon dactylon), stargrass (Cynodon nlemfuensis), limpograss (Hemarthria altissima), big bluestem (Andropogon gerardii), purple bluestem (Andropogon glomeratus var. glaucopsis), yellow indiangrass (Sorghastrum nutans), lopsided indiangrass (Sorghastrum secundum), switchgrass (Panicum virgatum), rhizoma perennial peanut (Arachis glabrata), and carpon desmodium (Desmodium heterocarpon). Warm season annual forage species often include browntop millet (Urochloa ramosa), pearl millet (Pennisetum glaucum), sorghum (Sorghum bicolor), hairy indigo (Indigofera hirsuta), and aeschynomene (Aeschynomene americana). Cool season annual forage species often include annual ryegrass (Lolium perenne ssp. multiflorum), oat (Avena sativa), rye (Secale cereale), wheat (Triticum aestivum), white clover (Trifolium repens) and Triticale (x Triticosecale rimpaui). Several additional plants and/or species combinations maybe present depending on the objectives and management approaches of the land manager/owner.
Resilience management. Soils in this community are similar to R155XY030FL in all characteristics except the presence of a loamy sand subsoil at 20 to 40 inches. Total production of warm season forage species is expected to be more consistent than for R155XY030FL. Better production can be expected during the spring due to better water holding capacity of the subsoil, particularly in the southern half of the MLRA where temperatures should not be limiting to warm season grass growth. Use of cool season forages such as annual ryegrass, oats, and wheat planted in a prepared seedbed can be more productive than R155XY030FL due to the better water holding capacity of the subsoil. Limited and sporadic rainfall during fall and winter months, particularly in the southern half of this MLRA, will still limit use of cool season annuals. Additionally in the southern portion of the MLRA, warm temperatures persisting into the fall and returning quickly in the spring greatly shorten the production period for cool season forages. Thus in the southern portion of the MLRA, cool season forages generally will still only produce sufficient winter grazing in years with average and above average rainfall (El Niño winters) for specialized management uses such as creep grazing, early weaning, or purebred operations. While in more northerly locations in the MLRA, planting winter annual forages for use as a winter feed supply for the whole cow herd may be practical most years. Overseeding annual ryegrass on a bahiagrass pasture also is not recommended in the southern end of this MLRA, due to excessive competition from bahiagrass for soil moisture, but should be a better option in the northern portions of the MLRA. For similar reasons, winter legumes should be more productive, particularly in the northern portion of the MLRA. White clover, berseem clover, and ball clover should be considered on this FSG, particularly in the northern half of the MLRA. Grazing management and fertilization need to favor the legume component for persistence, productivity, and seed production when natural reseeding is desired. Grazing management for seed production also is important for white clover, normally considered a perennial species, functions more as an annual in Florida and thus is heavily dependent upon reseeding to persist. Due to bloat issue, clovers should be used only in mixtures with cool season grasses, overseeded on bahiagrass pastures, or when a bloat preventative supplement is fed. Initial growth of perennial warm season grasses and legumes or establishment of warm season annual grasses may be delayed in the spring due to low rainfall. Better water holding capacity of the subsoil should mitigate the effects of the typical April/May dry period. Once normal summer rainfall begins, plant production should resume. Warm season legumes such as aeschynomene and carpon desmodium can also be oversown onto warm season grasses in this forage suitability group, although fertilization (no N fertilizer) and grazing management needs to favor legume establishment and persistence. Additional lime may be needed to maintain a pH of 5.5 to 6.0. Improved grass varieties such as stargrass and limpograss may also be grown on these soils although stargrass is generally limited to the part of the MLRA south of the US I-4 corridor. Limpograss should be limited to soils where drainage has not been altered.

State 5
SilvicultureThis state is important and used by silviculturists, landowners, land managers, and the public/private industry. Silviculture is land used in controlling the establishment, growth, composition, health, and quality of forests and woodlands to meet the diverse needs and values of landowners and society such as wildlife habitat, timber, water resources, restoration, and recreation on a sustainable basis. These are forestry practices that include thinning, harvesting, planting, pruning, prescribed burning and site preparation, for managed goals such as wildlife habitat creation or harvesting.
Because of the generally wet soil conditions associated with forested wetlands, some of these areas can be very sensitive to forestry activities, particularly during flooded or periods of soil saturation. For silviculture operations in general, wetlands are probably most susceptible to changes in hydroperiod, which can result from improper forest road construction, logging operations, and certain types of site preparation activities. Due to management concerns within these wetlands, the creation and planting of tree plantations is not recommended and should be managed for stand harvesting and regeneration All silviculture operations should follow state and federal best management practices (BMP) to mitigate extensive damage to harvested wetlands.
These may include not significantly altering the natural drainage or flow patterns on forested lands, not conducting intensive mechanical site preparations such as bedding and fire line placement and avoiding road construction which may alter natural hydroperiod. For harvesting in these wetlands, specific criteria is used to prevent excessive damage to the natural system. These may include retaining leave trees for wildlife habitat and seeding, removing logging slash from the wetland system, minimizing heavy equipment operations which may cause extensive rutting, and only operating and harvesting in dry seasons/ periods or using specialized equipment in wetter conditions. It is strongly advised that consultation with State Resource Conservationist and District Conservationists at local NRCS Service Centers be sought when assistance is needed in developing management recommendations for silviculture practices.
Resilience management. This state is managed by silviculture prescriptions that will vary based on individual forest stand and management goals.
Community 5.1
Cypress - TupeloThis phase represents the prevailing composition and/or association of the species occurring on this site. In general, this wet site is not very productive and species richness is generally low. Because tree diversity is low, regeneration of cut stands may result in pure stands of cypress or tupelo or a mixed hardwood swamp consisting of cypress, bays, and maples. Additional complications arise from the difficulty of germination and seedling development due to excessively long hydroperiods. A dry cycle of several years may be the requirement for advancement of young seedlings in this environment. If the area is clear cut it may regenerate into a shrub – scrub wetland before transitioning into a forested wetland.
State 6
Reclaimed / Restored WetlandsThe reclaimed/ restored wetland state consists of non-forested and forested wetland communities which have undergone or currently undergoing transition from an altered state (agriculture field, pasture, forestry land, urban areas) to a restored natural community. These reclaimed and restored natural communities will be managed to reflect the natural vegetation, management regimes, and hydroperiods of the reference community, with a history of land modification. This can often be accomplished through programs offered by the NRCS such as the Wetland Reserve Easements (WRE), a voluntary program to help restore and enhance wetlands which have been previously degraded due to agricultural uses. Restored wetlands will provide habitat to fish and wildlife, improve water quality by filtering sediments and chemicals, reduce flooding, recharge groundwater, protect biological diversity, and provide resilience to climate change. It is strongly advised that consultation with State Resource Conservationist and District Conservationists at local NRCS Service Centers be sought when assistance is needed in developing management recommendations for silviculture practices.

Reclaimed / Restored Non-Forested WetlandsThis community described a reclaimed or restored non forested floodplain wetland community. Specific non-forested wetland community type will be dependent on local geomorphology, hydroperiods, fire regimes, and past management. While specific community type and species composition will depend on local factors, this community is unified through reclaimed or restored very poorly to poorly drained sandy over loamy soils which support non-forested wetlands on floodplains. Evidence of past management use (pasture/ agricultural uses) may be seen on the landscape. It may be common to see weedy or pasture forage species present in these areas along with native vegetation. These areas which have been converted back to non-forested wetlands are often under permanent or long-term (30 year) easement contracts. Restoration of a non-forested wetland is a long-term process to restore, protect, and enhance the restored wetland's function and values.

State 8
Human Altered and Human Transported Soil MaterialsThese areas include soils that were intentionally and substantially modified by humans for an intended purpose, commonly for terraced agriculture, building support, mining, transportation, and commerce. The alteration is of sufficient magnitude to result in the introduction of a new parent material (human-transported material) or a profound change in the previously existing parent material (human-altered material). They do not include soils modified through standard agricultural practices or farmed soils with unintended wind and water erosion. When a soil is on or above an anthropogenic landform or microfeature, it can be definitely be associated with human activity and is assigned to a unique taxon, usually found as an "Urban land complex" within that communities' natural soil properties (e.g, Pineda fine sand-Urban land complex, frequently flooded, 0 to 2 percent slopes).
Characteristics and indicators. Evidence of these areas include soils with manufactured items (e.g. artifacts) present in the profile, human altered-materials (e.g., deeply excavated soil) or human-transported material (e.g., fill), and position on or above anthropogenic landforms (e.g., flood-control levees) and microfeatures (e.g., drainage ditches). Detailed criteria regarding the identification of anthropogenic (artificial) landforms, human-altered materials, and human-transported material are in the "Keys to Soil Taxonomy" (Soil Survey Staff, 2014).
Community 8.1
UrbanThis urban community consists of development for human use. Urban areas include a variety of land uses, e.g., inner city or urban core, industrial and residential areas, cemeteries, parks, and other open spaces; the overall function which may benefit the quality of human life. These often form an urban soil mosaic, where the natural landscape has been fragmented into parcels with distinctive disturbance and management regimes and, as a result, distinctive characteristic soil properties.
Resilience management. Within this community there are three different levels of urbanization, based off population dynamics, residential density, and intensity of development. These are labeled as low-intensity, medium-intensity, and high-intensity urban areas, which can eventually be split apart into its own separate state. Low-intensity urban areas may consist of single dwelling homes with little impact on the surrounding community which still somewhat represents the natural community (e.g., represents natural landscape, hydrology, and vegetation) , other examples of this are urban parks, cemeteries, or campgrounds with little urban development. Medium-intensity urban areas consist of larger urban dwellings with some natural features but have been modified to meet urban needs (e.g., towns). High-intensity urban areas are areas of heavily modified areas with complete alterations of the natural landscape, hydrology, and vegetation to support a very large population, which once constructed is permanently altered (e.g., metropolis areas/ active mines).
Community 8.2
CanalsThis community consists of the creation and channelization of anthropogenic waterways for water control use and floodwater protection. Primary purposes of these systems are to transport floodwaters and reduce flood damage to upland communities in the area. These will often be seen as straight channels of variable depths and width which will permanently hold standing water. These systems are often dug with heavy machinery through the natural floodplain community. Artificial impoundment areas will often be constructed along the banks of these areas to provide more water control during periods of heavy flow. In more naturalized areas, these created canals will grade directly into a marsh or swamp system with no impoundment system. These areas will often alter the hydrology of the floodplain communities, allowing for more shrubby species to become prevalent in these areas as the majority of water is directed out of the system. Within the canal system itself, the area is dominated by open water which may support floating aquatic species.
Community 8.3
Impoundment AreasThis community is often seen in conjunction with the creation and channelization of anthropogenic waterways as deposited spoil materials creating artificial impoundment areas. These areas will often be seen immediately adjacent to a natural floodplain system or an altered canal system. These are often called levees, dikes, or spoil areas. They will range in height, shape, and slope, but can often be identified as rises in the immediate area next to a flooded waterbody. They will often be dominated by invasive or weedy grasses and shrubs along the lower base of the impoundment where moisture is more readily available. The top of these areas will often consist of bare sand or sparse weedy species due to more xeric conditions. These will often be mapped as an individual HAHT soil map unit such as "arents", and will be composed primarily of sandy, with some shell, clay and limerock which is slightly alkaline by nature.
Transition T1A
State 1 to 2
Non - Forested Wetlands
Forested WetlandsThis transition is driven by the introduction and establishment of cypress. This may occur if the area is seeded (anthropogenically or naturally) and the hydroperiod is short enough (as in extreme drought years) for cypress to germinate and become established before seasonal flooding occurs. This maybe seen as a mixed stand of hardwoods and cypress species in an even aged stand or a pure overstory of cypress with a shrubby understory. Trees will often be greater than 20 feet (6 meters) in height.
Transition T1B
State 1 to 3This mechanism is driven by the introduction of livestock species to the natural system and implementing a planned grazing strategy. Use of a planned grazing strategy to balance animal forage demand with available forage resources. Timing, duration, and frequency of grazing are controlled and some type of grazing rotation is applied to allow for plant recovery following grazing. It is strongly advised that consultation with State Resource Conservationist and District Conservationists at local NRCS Service Centers be sought when assistance is needed in developing management recommendations or prescribed grazing practices.
Transition T1C
State 1 to 4Actions required to convert native habitat to pasture or forage production include herbicide application, seedbed preparation, and the establishment of desired plants. Decisions to convert native land to pastureland on this site should be made carefully and continuously evaluated before, during, and after conversion activities. This site is extremely susceptible to soil compaction and erosion. The decision to proceed with this action may have occurred before the regulation of wetlands within the state of Florida. Conversion may still be allowed if the proper permits are gathered in accordance with local, state, and federal regulations.

Transition T2A
State 2 to 1
Forested Wetlands
Non - Forested WetlandsThis transition is driven by severe fire, usually occurring in periods of drought, or from anthropogenic decrease in the natural hydroperiod. If the roots were protected from fire, many species will rapidly re-sprout and form a shrub –scrub wetland. If the root systems were destroyed, these areas may be colonized by marsh grasses. Areas subject to removal of tree species via logging practices may be recolonized by a shrub – scrub wetland if not replanted and managed for its reference forested wetland community.

Animal community
During the summer months when standing water is present aquatic insects and other invertebrates which inhabit these communities can be abundant in these communities and serve as an important food source for many other organisms in the food web. Many of these invertebrates such as crayfish (Procambarus spp.), glass shrimp (Palaemonetes spp.), seed shrimp (Ostracoda), and small side swimmers (Amphipoda) are widespread and feed on detritus, attributing to the breakdown of soil organic material in these systems. Snails and mollusks including the pouch snail (Physella spp.), Florida apple snail (Pomacea paludosa), fingernail clams (Musculium spp., Sphaerium spp.), and freshwater limpets (Ancylidae) provide food for many bird species. Insects such as mayflies (Ephemeroptera), larval flies (Diptera), midges (Chironomidae), and mosquitoes (Culicidae) use these habitats as spawning habitat. Many of these insects are prey to species such as dragonflies and damselflies (Odonata).
Floodplain wetlands provide a biodiverse habitat for fish species, especially larger game species. These habitats are more diverse than isolated depressional wetlands as the seasonal overflow of a riverine system in which the fish are permanent residents becomes more extensive. Some fish utilize these wetlands to complete their lifecycle, primarily for spawning and as nursery areas for juvenile fish which require slow moving water. These floodplain wetlands also create more available feeding grounds, which are usually rich in invertebrate prey because of the presence of decaying plant material, algae, and other food sources. Common fish in these wetlands include sunfish (Lepomis spp.), bass (Micropterus spp.), crappie (Pomoxis nigromaculatus), and minnows (Notropis spp.).
Larger reptiles such as the American alligator (Alligator mississippiensis), common cooters (Pseudemys floridana), and common snapping turtles (Chelydra serpentine) utilize the wetlands as feeding areas, while utilizing upland wetlands for nesting areas.
Aquatic vegetation found in these wetlands provides abundant supplies for birds and other wildlife with food, foraging ground, nest-building areas, nurseries, and shelter from both weather and predators. Many birds have become adapted to exploit these wetland habitats via increased leg length and bill shape. Other important adaptations include webbed feet, rear leg placement, and water-resistant feathers are utilized by resident and migratory bird species to be successful in these habitats. Seasonal variations in water level, temperature, and supply of prey species will influence changes in species composition in marshes. Common species include herons, egrets, bitterns, rails, ibis, limpkins (Aramus guarauna), wood storks (Mycteria americana), snail kites (Rostrhamus sociabilis), and Florida sandhill cranes (Grus canadensis pratensis). Different species will utilize these different habitats in different ways, but often serve as indicators of wetland ecosystem integrity due to their close association with a particular community.
Mammals are not as abundant in these wetland communities as other animal species but will utilize these wetlands where and when abundant forage is found or for cover. Common species may include the racoon, marsh rabbit (Sylvilagus palustris), white-tailed deer (Odocoileus virginanus), and feral hogs (Sus scrofa). Hogs are considered invasive species and damage community structure of marshes and swamps by uprooting areas, allowing for the introduction of invasive or non-native species.Hydrological functions
The reference communities are natural storage areas for floodwater, slowing the flow of water, improving the water quality and assimilate inorganic and organic waste and reducing pollution levels. These areas are highly sensitive to changes in the water cycle and should be managed to protect hydrologic flow to maintain ecological integrity.
Recreational uses
These areas have limited recreational uses. In larger wetland communities these areas may be used for ecotours, birdwatching, and fishing. These areas are often used to provide opportunities for education and scientific activities.
Other products
Due to frequent periodic flooding, these areas are not typically utilized for agricultural uses. The primary altered uses may consist of grasslands utilized for range or if drained and cultivated, pasture, and forestlands utilized for silviculture operations of cypress and / or tupelo species.
