Animal Community – Wildlife Interpretations
Landscape

The MLRA 55B landscape is characterized by mostly nearly level to gently rolling till plains with some steep slopes adjacent to streams and many poorly defined drainage channels. The continental drainage divide occurs in the east central part of the MLRA. The MLRA is located within the Prairie Pothole Region with temporary, seasonal, and semi-permanent wetlands throughout the MLRA. The MLRA includes areas of eskers, kames, and ground moraines. MLRA 55B is considered to have a continental climate with cold winters and hot summers, low humidity, light rainfall, and much sunshine. Extremes in temperature are common and characteristic of the MLRA. This area supports mid- to tall-grass prairie vegetation with American elm, bur oak, green ash, and willow species growing along the riparian zones of river systems found throughout the MLRA. Complex intermingled ecological sites create diverse grass/shrub land habitats interspersed with varying densities of linear, slope, depressional, and in-stream wetlands associated with headwater streams and tributaries of the James, Pipestem, Maple, Goose, Sheyenne, Wild Rice, and Elm Rivers. MLRA 55B is located within North and South Dakota and within the boundaries of the Prairie Pothole Region.

Three Hydrologic Unit Areas make up this MLRA. Approximately 6% drains into the Mouse River into MLRA 55A, with the balance split between the James and Sheyenne Rivers.

By the mid-19th century, over 76% of the MLRA had been converted from mid- to tall-grass prairie to annual crop production. To alleviate crop production loss from wetlands and overland flow, a system of shallow surface ditches, judicial ditches, and road ditches removes surface water in spring and during high rainfall events. Tile drainage systems have been or are being installed extensively throughout MLRA 55B for sub-surface field drainage to enhance annual crop production.

Historic Communities/Conditions within MLRA 55B:

The northern tall- and mixed-grass prairie were disturbance-driven ecosystems with fire, herbivory, and climate functions as the primary ecological drivers (either singly or often in combination). American bison roamed MLRA 55B, wintering along the Mouse River in MLRA 55A and migrating through MLRA 55B and into MLRA 56A. Many species of grassland birds, small mammals, insects, reptiles, amphibians, elk, moose, pronghorn, white-tailed deer, and large herds of American bison were historically among the inhabitants adapted to this region. Roaming herbivores, as well as several small mammals and insect species, were the primary consumers linking the grassland resources to large predators (such as the wolf, American black bear, grizzly bear) and smaller carnivores (such as the coyote, bobcat, red fox, and raptors). Extirpated species include free- ranging American bison and gray wolf (breeding). Extinct is the Rocky Mountain locust.

Present Communities/Conditions within MLRA 55B:

This area supports natural prairie vegetation characterized by western wheatgrass, green needlegrass, needle and thread, and blue grama. Little bluestem is an important species on the more sloping and shallower soils. Prairie cordgrass, northern reedgrass, big bluestem, and wheat sedge (aka slough sedge) are important species on wet soils. Western snowberry, leadplant, and prairie rose are commonly interspersed throughout the area.

Over 80% of MLRA 55B has been converted to annual crop production. These influences fragmented the landscape, reduced, or eliminated ecological drivers (fire), and introduced exotic plant species including smooth brome, crested wheatgrass, Kentucky bluegrass, and leafy spurge; this further impacted plant and animal communities. The loss of the bison and fire as primary ecological drivers greatly influenced the character of the remaining native plant communities and the associated wildlife, moving towards a less diverse and more homogeneous landscape. Annual cropping is the main factor contributing to habitat fragmentation, reducing habitat quality for area- sensitive species.

Hydrological manipulation is extensive throughout the MLRA. Extensive wetland and subsurface tile drainage have taken place. Straightened segments of ephemeral and intermittent tributary streams of the James, Wild Rice, and Sheyenne River have reduced sinuosity, created oxbows, and enabled the conversion of riparian ecological sites to annual crop production. These anthropogenic impacts have reduced flood water detention and retention on the landscape. The results have been increasing storm water runoff sediment and nutrient loading to the James and Sheyenne Rivers and their tributaries (along with lakes and reservoirs within the MLRA). Large dams on the James, Pipestem and Sheyenne rivers, along with installation of instream structures have reduced aquatic species movement within the MLRA.

National wildlife refuges, waterfowl production areas, state wildlife management areas, and North and South Dakota Department of Trust Lands provide herbaceous and woody cover for wildlife. In addition, the United States Army Corps of Engineers and the United States Bureau of Reclamation manage three man-made reservoirs - Jamestown Reservoir, Pipestem Reservoir, and Lake Ashtabula for flood control, also providing fish habitat and adjacent uplands for wildlife cover.

Lonetree Wildlife Management Area (WMA) is the largest state managed wildlife area covering 32,800 acres. Arrowwood National Wildlife Refuge is the largest refuge consisting of 16,000 acres.

Characteristic wildlife species in this area are:

Birds: Common goldeye, bufflehead, broad-winged hawk, alder flycatcher, mourning warbler, mallard, blue-winged teal, red-tailed hawk, American kestrel, killdeer, eastern and western kingbird, western meadowlark, American crow, common yellowthroat, clay-colored sparrow, vesper sparrow, red-necked grebe, Savannah sparrow, downy and hairy woodpeckers, black-capped chickadee, white-breasted nuthatch, and brown-headed cowbird.

Mammals: Northern short-tailed shrew, white-tailed jackrabbit, Franklin’s ground squirrel, thirteen- lined ground squirrel, northern pocket gopher, plains pocket gopher, western harvest mouse, deer mouse, meadow vole, meadow jumping mouse, western jumping mouse, coyote, red fox, racoon, American badger, striped skunk, white-tailed deer, elk, moose, beaver, muskrat, mink, weasel, woodchuck, and red, eastern gray and fox squirrels.

Reptiles/Amphibians: American toad, Great Plains toad, northern leopard frog, chorus frog, tiger salamander, plains garter snake, smooth green snake, wood frog, and common garter snake.

Presence of wildlife species is often determined by ecological site characteristics including grass and forb species, tree and shrub species, hydrology, aspect, and other associated ecological sites. The home ranges of a majority of species are usually larger than one ecological site or are dependent upon more than one ecological site for annual life requisites. Ecological sites offer different habitat elements as the annual life requisites change. Habitat improvement and creation must be conducted within the mobility limits of a known population for the species.

Insects play an important role in providing ecological services for plant community development. Insects that are scavengers or aid in decomposition provide the food chain baseline sustaining the carnivorous insects feeding upon them. Many insects provide the ecological services necessary for pollination, keeping plant communities healthy and productive. Insects provide a protein food source for numerous species including grassland-nesting birds, woodpeckers, woodland edge and interior species, and their young. Extensive use of insecticides for specialty crops such as soybeans, corn, and other crops has greatly reduced insects within this MLRA.

Grassland Management for Wildlife in the MLRA 55B

Management activities within the community phase pathways impact wildlife but are essential for maintenance of healthy grassland ecosystems. Community phase, transitional, and restoration pathways are keys to long-term management within each State and between States. Timing, intensity, and frequency of these inputs can have dramatic positive or negative effects on local wildlife species. Ranchers and other land managers must always consider the long-term beneficial management effects of grassland and woodland resources in comparison to typically short-term negative effects to the habitats of individual species.

Ecological sites occur as intermingled complexes on the landscape with gradual or sometimes abrupt transitions. Rarely do ecological sites exist in large enough acreage to manage independently. Ecological sites supporting a dominance of herbaceous vegetation (Loamy/Sandy) can be located adjacent to ecological sites that support medium to tall shrubs (Loamy Overflow or Loamy- Invaded Wooded State). Conversely, ecological sites that are dominated by short- to mid-statured grasses (Claypan) can be adjacent to sites with bare soil only supporting a minor amount of short grasses and forbs (Thin Claypan).

Management of these complex ecological sites can provide a heterogeneous or a homogenous landscape. Grassland bird use reduces as the plant community transitions to a homogenous state. Managers must recognize ecological sites and the complexes in which they occur to properly manage the landscape. A management regime for one ecological site may negatively impact an adjacent site; for example, alteration of a grazing regime within the Invaded Wooded State of a Loamy ecological site to encourage understory growth may encourage exotic, cool-season grasses to increase or dominate an adjacent ecological site.

Life requisites and habitat deficiencies are determined for targeted species. Deficiencies need to be addressed along community phase, transitional, and restoration pathways as presented in specific state-and-transition models. Ecological sites should be managed and restored within the site’s capabilities to provide sustainable habitat for targeted species or species guilds. Managers also need to consider vegetative associations provided by adjacent/intermingled ecological sites for species with home ranges or life requisites that may not be provided by one ecological site.

Grassland-nesting birds use various grass heights for breeding, nesting, foraging, or winter habitat. While most species use varying heights, many have a preferred vegetative stature height or sensitivity to woody vegetation. Understanding the sensitivity of grassland species to woody vegetation and preferred vegetative structure enables managers to determine which grassland-nesting bird species avoid grassland habitats adjacent to woody dominated plant community. The following chart provides sensitivity to woody vegetation and preferred vegetative stature heights.

Sands Wildlife Habitat Interpretation:

Sands ecological sites are very deep, coarse textured (non-gravelly), well to excessively drained soils. They are usually found on eolian sand sheets, sandy lake plains, and outwash plains but can also occur on till plains mantled with eolian sands. No significant water table or surface run-on influences vegetation production on this site. These soils are susceptible to wind erosion. Associated ecological sites include Sandy, Choppy Sands, Sandy Claypan, Subirrigated Sands, and Thin Loamy. This complex of ecological sites provides habitat for many edge-sensitive, grassland bird species preferring medium- to tall-statured vegetation.

This site is very similar to the Sandy ecological site in plant community structure and wildlife interpretations. Sands ecological sites may be found in three plant community states (1.0 Reference State, 2.0 Native/Invaded State, 3.0 Invaded State) within a local landscape. Multiple plant community phases exist within all States. Today, these states occur primarily in response to drought, fire, grazing, non-use, and other anthropogenic disturbances.

Because there is no known restoration pathway from State 2.0 to State 1.0, it is important to intensively manage using tools in State 1.0 and State 2.0 Community Phase Pathways to prevent further plant community degradation along the Transitional Pathway T2A to Community Phase 3.1. Native wildlife generally benefits from the heterogeneous grasslands found in Community Phases found in States 1.0 and 2.0 that include diverse grass and forb species of varying stature and density. As plant communities degrade within State 2.0, Kentucky bluegrass increases while native forbs are reduced. When Kentucky bluegrass exceeds 30%, the site transitions to 3.0 Invaded State. This transition results in reduced stature and increased plant community homogeneity. When adjacent and/or intermingled ecological sites undergo the same transition, the result can be an expansive, homogenous landscape.

Success along Restoration Pathways R3A from State 3.0 to State 2.0 is very difficult and is dependent upon presence of a remnant native grass population. This concept also applies to wildlife as the target species must either be present on adjacent State 1.0 or State 2.0 plant communities or on other ecological sites within the mobility limits of the species. Species with limited mobility, such as Dakota skippers, must exist near the plant community to utilize restored sites. Mobile species (such as grassland-nesting birds) can easily locate isolated, restored plant communities.

Plant Community Phases 3.1 shows dramatic increased homogeneity of exotic cool-season grasses and further reduction in native forbs. Reduced forb diversity limits insect populations, negatively affecting foraging opportunities for grassland-nesting birds. Increased exotic grass litter can limit access to bare ground by nesting insects and can limit mobility by small chicks. A homogenous grassland landscape does not provide quality escape or winter cover. As a result, many species are not able to meet life requisites, especially non-migrating bird species.

Management along community phase, transition, or restoration pathways should focus upon attainable changes. Short- and long-term monetary costs must be evaluated against short- and long- term ecological services in creating and maintaining habitat of sufficient quality to support a sustainable population density.

1.0 Reference State

Community Phase 1.1 Needlegrasses-Prairie Sandreed-Bluestems: This plant community offers quality vegetative cover for wildlife; every effort should be made to maintain this ecological site within this community phase. This phase retains high functionality through continued grassland management including prescribed grazing with adequate recovery period as well as prescribed fire. Predominance of grass species in this community favors grazers and mixed-feeders (animals selecting grasses as well as forbs and shrubs). The structural diversity provides habitat for a wide array of migratory and resident birds.

Invertebrates: Insects play a role in maintaining the forb community and provide a forage base for grassland birds, reptiles, and rodents. Ecological services, historically provided by bison, are simulated by domestic livestock. These services include putting plant material and dung in contact with mineral soil to be used by lower trophic level consumers (such as invertebrate decomposers, scavengers, shredders, predators, herbivores, dung beetles, and fungal-feeders).

Dakota skippers do not prefer this site due to unavailability of host plants (such as blacksamson echinacea, wood lily, harebell, and mountain deathcamas). Similarly, host plants for the Ottoe skipper (such as blacksamson echinacea) are absent on this ecological site. Violet species are not common on this site, not supporting the needed habitat for the regal fritillary. Monarch butterfly may use flowering forbs. The ecological site may provide habitat for the northern sandy tiger beetle which prefers dry, sandy dunes and sandy areas away from water. Bumblebees and other native bees utilize forbs as a nectar source; bare ground and nesting sites are available due to the co-dominance of bunch grasses.

Birds: This plant community provides quality nesting, foraging, and escape habitats favored by mid- to tall-grass nesting birds. Prescribed fire maintains a grass-dominated plant community providing habitat for bird species sensitive to woody vegetation. In years with reduced precipitation or drought, nesting recruitment may be compromised. This plant community is too tall and dense to provide suitable lek sites for sharp-tailed grouse but does provide nesting, brood-rearing, and escape habitat. This site provides good hunting opportunities for grassland raptors.

Mammals: The diversity of grasses and forbs provide high nutrition levels for small and large herbivores. Tall- to mid-statured vegetation provides suitable food and thermal, protective, and escape cover for small and large mammals.

Amphibians and Reptiles: This ecological site is not typically found adjacent to Wet Meadow or Shallow Marsh ecological sites. Habitat for the northern leopard frog and Canadian toad is dependent upon distance to water features such as wetlands, lakes, or streams. This site provides habitat for the northern prairie skink (secondary range in MLRA 55B) and plains hog-nosed snake.

Fish and Mussels: This ecological site is not typically adjacent to streams, rivers, or water bodies. This site receives limited run-on hydrology from adjacent ecological sites; it provides hydrology to Subirrigated Sands ecological sites. Management on Sands sites, in conjunction with neighboring run-on sites, will have an indirect effect on aquatic species in streams and/or tributaries receiving water from Sands and adjacent sites. Optimum hydrological function and nutrient cycling limit potential for sediment yield and nutrient loading to the nearby aquatic ecosystems from Community Phase 1.1.

Community Phase 1.2 Needle and Thread-Blue Grama/Sedges/Prairie Sandreed: Short- to mid- statured grasses dominate this plant community phase due to multiyear drought with or without heavy grazing (via Community Phase Pathway 1.1A). Facilitated by periods of below normal precipitation the tall, warm-season grass component has decreased with increases in shorter statured blue grama and sedges along with field sagewort, goldenrod, Cuman ragweed, common yarrow, and upright prairie coneflower.

Invertebrates: An increase in wind-pollinated field sagewort and Cuman ragweed reduces season- long pollen production. Goldenrod provide last-season pollen, while common yarrow is favored by flies and small bees. Increases in sedges and blue grama also increase bare ground availability for ground nesting bee species.

Birds: An increase in short- to mid-grass species favors grassland-nesting birds that prefer short- to mid-statured vegetation. The forb component provides pollinator habitat and a food source for grassland-nesting birds.

Mammals: Overall plant stature is reduced in this phase, reducing cover for large ungulates. This plant community phase continues to provide life requisites for small mammals.

Amphibians and Reptiles: Provides similar life requisites as Community Phase 1.1.

Fish and Mussels: Provides similar life requisites as Community Phase 1.1.

2.0 Native/Invaded State

Community Phase 2.1 Needlegrasses-Prairie Sandreed-Bluestems: This plant community develops through Transition Pathway T1A due to changes in management (reduction in fire frequency) and the presence of exotic, cool-season grasses. This historic grazing/fire sequence has largely been replaced by chronic season-long or heavy late-season grazing. Complete rest from grazing and suppression of fire can also lead to this transition. The threshold between States 1.0 and 2.0 is crossed when Kentucky bluegrass or smooth brome become established. This plant community phase has a very similar appearance and function to the Plant Community 1.1, except that it has a minor amount of cool-season exotic grasses and forbs. This phase functions at a high level for native wildlife; therefore, managers can maintain this community phase with grazing systems that allow for adequate recovery periods following grazing events and, potentially, the combination of grazing and prescribed burning which closely mimics the natural disturbance regime. Managers need to consider management within the State 2.0 Community Phase Pathways to avoid transitioning to State 3.0.

Invertebrates: Provides similar life requisites as Community Phase 1.1.

Birds: Provides similar life requisites as Community Phase 1.1.

Mammals: Provides similar life requisites as Community Phase 1.1.

Amphibians and Reptiles: Provides similar life requisites as Community Phase 1.1.

Fish and Mussels: Provides similar life requisites as Community Phase 1.1.

Community Phase 2.2 Needle and Thread-Blue Grama/Sedges/Prairie Sandreed: Multiyear drought with or without heavy continuous grazing increases grazing tolerant needle and thread while decreasing porcupine grass. Shorter, sod-forming grasses increase while bunch grasses decrease. The forb component is still diverse; however, leguminous native forbs are decreasing and less desirable, native pollinator forb species (such as common yarrow, field sagewort, and white sagebrush) and shrubs (such as prairie sagewort) are increasing. Every effort should be made by managers to avoid implementing a grazing system that may favor Kentucky bluegrass (via Community Phase Pathway 2.2B or Transitional Pathway T2A). Continuous, heavy season-long grazing or complete rest could cause this plant community to reach the 30 percent threshold of Kentucky bluegrass, crossing over to State 3.0 with little chance of restoration back to State 2.0.

Invertebrates: Provides similar life requisites as Community Phase 1.2. However, the forb community is shifting toward less desirable forb species (such as wind-pollinated field sagewort and white sagebrush) and wind-pollinated shrubs, such as prairie sagewort.

Birds: Provides similar life requisites as Community Phase 1.2.

Mammals: Provides similar life requisites as Community Phase 1.2.

Amphibians and Reptiles: Provides similar life requisites as Community Phase 1.1.

Fish and Mussels: Provides similar life requisites as Community Phase 1.1.

Community Phase 2.3 Needle and Thread/Forbs/Exotic Cool-Season Grasses: Extended periods of non-use or very light grazing, and no fire (along Community Pathway 2.1B or 2.2B) leads to community phase characterized by shorter-statured grasses, including the increase of cool-season exotic grass and the reduction of prairie sandreed. This is an “at risk” plant community with high amounts of Kentucky bluegrass out-completing native grasses. Every effort should be made by managers to avoid implementing a grazing system that may favor reaching the 30 percent threshold for Kentucky bluegrass via Transitional Pathways T2A and T2B. When this plant community transitions over to State 3.0, it has little chance of restoration back to State 2.0 by implementing a prescribed grazing system and introducing prescribed fire.

Invertebrates: An increase in exotic cool-season grasses and a reduction in forbs reduces pollen and nectar sources, limiting use by pollination insect species. White heath aster, goldenrod, and white sagebrush are the main pollinator species. Increased litter may begin to limit ground nesting insect opportunities.

Birds: Grassland-nesting birds that favor short-statured vegetative cover will use this site. However, continuous non-use and no fire increases exotic cool-season exotic grasses, reducing use by grassland nesting birds.

Mammals: As exotic cool-season grasses increase, thermal, protective or escape cover becomes limited.

Amphibians and Reptiles: Provides similar life requisites as Community Phase 1.1.

Fish and Mussels: Although, this ecological site is not typically adjacent to streams, rivers, or water bodies, runoff from Community Phase 2.3 increases due to management that increases short- statured grass and reduces bunch grasses. Management of this community phase, in conjunction with neighboring run-on sites, will have an indirect negative effect on aquatic species in streams and/or tributaries receiving water from Sands and adjacent sites.

Invaded State 3.0

Community Phase 3.1 Exotic Cool-Season Grasses/Forbs: Community Phase Pathway T2A is characterized by non-use and elimination of fire when exotic cool-season grasses are present (as in Community Phase 2.0). This plant community phase is characterized by a dominance (>30%) of exotic cool-season grasses, such as smooth brome; native grasses represent less than 40% of the plant community. Restoration Pathway R3A, through prescribed burning and high levels of grazing management, requires remnant amounts of native warm- and cool-season and forbs to be successful. The remnant native community needs frequent prescribed burns and high levels of grazing management targeting the exotic, cool-season grasses to improve competitiveness and increase vigor and density. Without intensive management, the remnant native plants will not increase adequately to transition back to State 2.0. Intensified management along the R3A Pathway will have significant short-term negative impacts on wildlife habitat; however, this is necessary to restore long-term native habitat functions.

Restoration Pathway R3A, through prescribed burning and high levels of grazing management, requires remnant amounts of native warm- and cool-season and forbs to be successful. The remnant native community needs frequent prescribed burns and high levels of grazing management targeting the exotic cool-season grasses to improve competitiveness and increase vigor and density. Without intensive management, the remnant native plants will not increase adequately to transition back to State 2.0. Intensified management along the R3A Pathway will have significant short-term negative impacts on wildlife habitat; however, this is necessary to restore long-term native habitat functions.

Invertebrates: Exotic grasses limit use by beneficial insects provided in States 1.0 and 2.0. Increased litter and lack of grazing leads to limited contact between plant material and mineral soil resulting in a cooler micro-climate, which is unfavorable to most insects. Lack of bare soil limits ground-nesting sites for native bees and other ground-nesting insects. The lack of nectar-producing plants limits forage opportunities for bumblebees, regal fritillary, monarch butterfly, and other pollinating species. This Community Phase does not provide life requisites for any species of concern within MLRA 55B.

Birds: The homogeneous community phase, dominated by exotic plant species, provides limited habitat and life requisites for most obligate grassland-nesting birds. Lack of plant diversity and stature, along with increased litter and the tendency of Kentucky bluegrass and smooth brome to lay down, limits use by many grassland-nesting birds. Sharp-tailed grouse may use this plant community for lek sites and nesting cover; however, winter cover must be provided by adjacent ecological sites or plant communities.

Mammals: Litter accumulation and exotic grass cover favors thermal, protective, and escape cover for small rodents.

Amphibians and Reptiles: Provides similar life requisites as Community Phase 1.1.

Fish and Mussels: Provides similar life requisites as Community Phase 1.1.

4.0 Go-Back State

Community Phase 4.1 Annual/Pioneer Perennial/Exotics: These plant communities are the result of severe soil disturbance (such as cropping, recreational activity, or concentrated livestock activity for a prolonged period). Following cessation of disturbances, the resulting plant community is dominated by early pioneer annual and perennial plant species. Plant species composition and production are highly variable. Weedy plants can provide pollinator habitat along with spring and summer cover for many mammals and birds and their young. Dense weed cover can keep soils moist, increasing insect presence. Tall stature provided by some weeds such as marsh elder and ragweed offer thermal cover and seeds throughout winter. The response by wildlife species will be dependent upon plant community composition, vegetative stature, patch size, and management activities (such as prescribed grazing, burning, inter-seeding, haying, or noxious weed control). Successful restoration of native species along Transition Pathway R4A can result in a native grass and forb community in State 2.0. Hydrological and nutrient cycling can be greatly reduced depending upon vegetation composition. Sites with poor species diversity and density have high potential for erosion and low nutrient cycling.

Animal Community – Grazing Interpretations
This site is well adapted to managed grazing by domestic livestock. The predominance of herbaceous plants across all plant community phases best lends these sites to grazing by cattle, but other domestic grazers with differing diet preferences may also be a consideration depending upon management objectives. Often, the current plant community does not match any particular plant community (as described in the ecological site description). Because of this, a resource inventory is necessary to document plant composition and production. Proper interpretation of this inventory data will permit the establishment of a safe, initial stocking rate for the type and class of animals and level of grazing management. More accurate stocking rate estimates should eventually be calculated using actual stocking rate information and monitoring data.

NRCS defines prescribed grazing as “managing the harvest of vegetation with grazing and/or browsing animals with the intent to achieve specific ecological, economic, and management objectives”. As used in this site description, the term ‘prescribed grazing’ is intended to include multiple grazing management systems (e.g., rotational grazing, twice-over grazing, conservation grazing, targeted grazing, etc.) provided that, whatever management system is implemented, it meets the intent of prescribed grazing definition.

The basic grazing prescription addresses balancing forage demand (quality and quantity) with available forage, varying grazing and deferment periods from year-to-year, matching recovery/deferment periods to growing conditions when pastures are grazed more than once in a growing season, implementation of a contingency (e.g., drought) plan, and a monitoring plan. When the management goal is to facilitate change from one plant community phase or state to another, then the prescription needs to be designed to shift the competitive advantage to favor the native grass and forb species.

Grazing levels are noted within the plant community narratives and pathways in reference to grazing/prescribed grazing management. “Degree of utilization” is defined as the proportion of the current years forage production that is consumed and/or destroyed by grazing animals (may refer to a single plant species or a portion or all the vegetation). “Grazing utilization” is classified as slight, moderate, full, close, and severe (see the following table for description of each grazing use category). The following utilization levels are also described in the Ranchers Guide to Grassland Management IV. Utilization levels are determined by using the landscape appearance method as outlined in the Interagency Technical Reference “Utilization Studies and Residual Measurements” 1734-3.


Utilization Level % Use Description
Slight (Light) 0-20 Appears practically undisturbed when viewed obliquely. Only choice areas and forage utilized.

Moderate 20-40 Almost all of accessible range shows grazing. Little or no use of poor forage. Little evidence of trailing to grazing.

Full 40-60 All fully accessible areas are grazed. The major sites have key forage species properly utilized (about half taken, half left). Points of concentration with overuse limited to 5 to 10 percent of accessible area.

Close (Heavy) 60-80 All accessible range plainly shows use and major sections closely cropped. Livestock forced to use less desirable forage, considering seasonal preference.

Severe > 80 Key forage species completely used. Low-value forages are dominant.

Hydrological functions

Available water is the principal factor limiting herbage production on this site. The site is dominated by soils in hydrologic group A, but some soils in group B are included. Infiltration varies from moderately rapid to rapid; runoff potential varies from negligible to low for this site depending on soil hydrologic group, surface texture, slope percent, and ground cover. In many cases, areas with greater than 75% ground cover have the greatest potential for high infiltration and lower runoff. An exception would be where short-grasses form a dense sod and dominate the site. Areas where ground cover is less than 50% have the greatest potential to have reduced infiltration and higher runoff (refer to Section 4, NRCS National Engineering Handbook for runoff quantities and hydrologic curves).

Recreational uses

Hunting and Bird Watching: National wildlife refuges, waterfowl production areas, state wildlife management areas (WMA), and North Dakota and South Dakota Department of Trust Lands provide herbaceous and woody cover for wildlife. National Wildlife Refuges and waterfowl production areas are owned and managed by the United States Fish and Wildlife Service and are available for public hunting, hiking, and bird watching. In addition, the United States Army Corps of Engineers and the United States Bureau of Reclamation manage three man-made reservoirs - Jamestown Reservoir (2,036 acres), Pipestem Reservoir (1,027 acres), and Lake Ashtabula (5,174 acres) for flood control, also providing fish habitat and adjacent uplands for wildlife cover.

Lonetree WMA is the largest state managed wildlife area covering 32,800 acres. Numerous WMAs in North Dakota and Game Production Areas in South Dakota are found within this MLRA. The largest refuges managed by the United States Fish and Wildlife service are Arrowwood National Wildlife Refuge (NWR) Complex consists of 75,000 acres and Tewaukon National NWR covers 8,363 acres.

Fishing: Approximately 100 lakes are managed for public fishing within MLRA 55B. Most of these lakes offer boat docks and ramps. These lakes contain various sport fish including walleye, northern pike, yellow perch, catfish, trout, crappie, and bluegill. Many of these lakes are known for excellent round-around walleye and yellow perch fishery.

Camping: Fort Ramson State Park, Pipestem Reservoir, Jamestown Reservoir, Spiritwood Lake, Clausen Springs, Little Yellowstone, Richmond Lake State Recreation Area, Mina Lake State Recreation Area, and other public and private campgrounds are found within the MLRA. Limited, primitive camping is available on wildlife management areas. Ft. Ransom State Park (North Dakota), located along the Sheyenne River has a designated horse park with 15 miles of trails.

Hiking/Biking/Horseback Riding: Horseback riders, hikers, and biker can enjoy over 15 miles of multi-use trails at Fort Ransom State Park. The Jamestown Reservoir (5 miles), Pipestem Reservoir (8 miles) and Arrowwood National Wildlife Refuge (9.4 miles) maintain hiking trails. The Lonetree Wildlife Management Area has a 32- mile segment of the North Country Trail. It is designed for hiking and non-motorized travel including mountain bikes or horseback riding.

Canoeing/Kayaking: The Sheyenne River offers 278 miles of canoeing/kayaking from May-July. A kayak kiosk is located at Valley City and canoe/kayak rentals are available at Fort Ransom State Park. The James River has a canoe trail starting in Grand Rapids and canoeing down to the James River Dam site in LaMoure; no rentals are available.

Auto Tour: A 63-mile scenic drive starts north of Valley City and heading south through Sheyenne River Valley. Audubon National Wildlife Refuge offers a 5.5-mile auto-tour route winding through both prairie grassland and wetland habitats of the lower portion of the James River Valley.

Site Development and Testing Plan
• Investigation is needed on the slope break of 15% between Sands and Choppy Sands. It is currently thought that the plant community and production on stable landscapes (not dunes) with slopes >15% is similar to that of dune areas. There is also uncertainty about the plant community and productivity of Serden soils (dunes) with slope <15% as compared to other soils in the Sands ecological site. The plant communities and production levels need more documentation to verify the current slope break.
-Further evaluation and refinement of the State-and-Transition model is needed to identify disturbance driven dynamics. Additional states and/or phases may be required to address grazing response.
• Further documentation may be needed for plant communities in all states. Plant data has been collected in previous range-site investigations, including clipping data; however, this data needs review. If geo-referenced sites meeting Tier 3 standards for either vegetative or soil data are not available, representative sites will be selected for further investigation.
• Site concepts will be refined as the above noted investigations are completed.
• The long-term goal is to complete an approved, correlated Ecological Site Description as defined by the National Ecological Site Handbook.

This ESD is the best available knowledge. The site concept and species composition table have been used in the field and tested for more than five years. It is expected that as additional information becomes available revisions may be required.

Inventory data references

Information presented here has been derived from NRCS and other federal/state agency clipping and inventory data. Also, field knowledge of range-trained personnel was used. All descriptions were peer reviewed and/or field-tested by various private, state and federal agency specialists.
