Wildlife Interpretations

Landscape:

The MLRA 58C landscape is characterized by moderately dissected rolling plains with areas of local Badlands, buttes, and isolated hills. MLRA 58C 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 natural mixed-grass prairie vegetation with prairie rose, leadplant, and patches of western snowberry interspersed throughout the area. Green ash, chokecherry, and buffaloberry occur in draws and narrow valleys, creating woody riparian corridors. Complex/intermingled ecological sites create diverse grass- and shrubland habitats interspersed with varying densities linear, slope, depressional, and in-stream wetlands associated with headwater streams and tributaries to the Missouri River. These habitats provide critical life-cycle components for many wildlife species.

Historic Communities/Conditions within MLRA 58C:

The northern mixed-grass prairie was a disturbance-driven ecosystem with fire, herbivory, and climate functioning as the primary ecological drivers (either singly or often in combination). Many species of grassland birds, small mammals, insects, reptiles, amphibians, and large herds of Audubon bighorn sheep, roaming bison, elk, and pronghorn were historically among the inhabitants adapted to this semi-arid region. Bighorn sheep have been re-introduced. Roaming herbivores, as well as several small mammal and insect species, were the primary consumers linking the grassland resources to large predators (such as the wolf, mountain lion, and grizzly bear) and smaller carnivores (such as the coyote, bobcat, red fox, and raptors). The black-tailed prairie dog was once abundant and provided ecological services by manipulating the plant and soil community providing habitat for the black-footed ferret, burrowing owl, ferruginous hawk, mountain plover, swift fox, small mammals, and amphibians and reptiles. Extirpated species include free-ranging American bison, Canada lynx, common raven, grizzly bear, gray wolf, black-footed ferret, mountain plover, and peregrine falcon (breeding). Extinct from the region is the Rocky Mountain locust.

Present Communities/Conditions within MLRA 58C:

Following European influence, domestic livestock grazing, elimination of fire, energy development, and other anthropogenic factors influenced plant community composition and abundance. Transportation corridors, energy development, and Rocky Mountain juniper and ponderosa pine encroachment are the main factors contributing to habitat fragmentation, reducing habitat quality for area-sensitive species. 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 further impacting plant and animal communities. The loss of the bison, reduction of black-tailed prairie dogs, 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, lacking diverse species composition and stature.

Extensive fragmentation by annual cropping has not occurred within the MLRA. Limited fragmentation from annual cropping or tame hay production has occurred within the Little Missouri River flood plain and the higher, flat plateaus. Fragmentation east and west of MLRA 58C has funneled many species into this area in search of expansive grasslands.

Some wildlife species in this area are: mule deer, white-tailed deer, elk, bighorn sheep, pronghorn, mountain lion, coyote, red fox, bobcat, prairie rattlesnake, American badger, raccoon, North American porcupine, beaver, striped skunk, American mink, white-tailed jackrabbit, black-tailed prairie dog, Eastern and Merriam’s wild turkey, golden eagle, ferruginous hawks, sharp-tailed grouse, greater sage-grouse, black-billed magpie, and numerous species of grassland-nesting birds and pollinating insects. The highest diversity of bats in North Dakota also occurs in this MLRA, where eleven species have been documented.

Presence of wildlife species is often determined by ecological site characteristics including grass and forb species, hydrology, aspect, and other associated ecological sites. Home ranges for most species are larger than one ecological site or are dependent on 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 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 and their young.

Species unique to the MLRA:

Mountain Lions: Mountain lions were relatively common in the Badlands but disappeared from the state by the early 20th Century. Sightings resumed in the 1950’s and have subsequently increased since that time. The species has recently taken up permanent residency within the region. Mountain lions occur in of the Little Missouri Badlands and woody habitat in MLRA 58C. Rugged terrain and forest provide excellent stalking cover to hunt large mammals and other prey. Mountain lions make use of caves for escape and loafing cover.

Bighorn sheep: Bighorn sheep make use of the rugged terrain, rocky outcrops, and high plateaus of MLRA 58C along the Little Missouri River. North Dakota bighorn sheep populations are almost exclusively within MLRA 58C. Bighorn sheep were once extirpated from North Dakota but were successfully reintroduced in the mid-twentieth century. They now occur in several distinct populations within MLRA 58C. Rocky Mountain juniper encroachment degrades the limited habitat for bighorn sheep. Managers should consider bighorn sheep association with domestic sheep, since transfer of pneumonia and other diseases is known to occur.

Golden eagle: The badlands within MLRA 58C are key areas for Golden eagle nesting. Adjacent grasslands, shrublands, and black-tailed prairie dog towns are used for hunting.

Bats: MLRA 58C provides life requisites for several bat species, in part due to presence of riparian forest, wooded draws, caves, and rocky outcrops. Hibernacula of six bat species have been found in MRLA 58C; however, additional work is needed to further understand utilization of hibernacula by bats during the winter months in North Dakota.

Short-horned lizard and sagebrush lizard: This MLRA provides preferred habitat for these two species. The short-horned lizard prefers semi-arid, shortgrass prairie in rough terrain, and is uncommon to locally abundant in MLRA 58C. The rare sagebrush lizard prefers sagebrush and rocky areas provided by this MLRA and adjacent MLRA 58D.

Greater sage-grouse and Brewer’s sparrow: The extreme southwest extension of MLRA 58C have ecological sites capable of producing sufficient big sage canopy cover to provide greater sage-grouse life requisites. MLRA 58C and 58D are the only MLRAs in North Dakota that support Wyoming big sage brush (big sage) production. Research data indicates greater sage-grouse prefer big sagebrush canopy cover for nesting at ≥8% with an average height of around 16 inches. The species prefers winter cover canopy that averages 15% with an average height of around 8 inches. Soil site potential, management, climate, and other factors all play a role in the amount, if any, of big sagebrush on an ecological site. Changes in big sage canopy cover occur slowly (30-50 years) unless the site is impacted by fire or cultivation. Big sage recovery after a burn can take 30 to 100 years. Greater sage- grouse and Brewer’s sparrow habitat and populations are reduced or eliminated when big sagebrush canopy is reduced to less than 8% for greater sage-grouse and 10% cover for Brewer’s sparrow. As conifer encroachment increases, greater sage-grouse lekking activity decreases. Once conifer encroachment exceeds 4% canopy cover, no leks remain.

Grassland Management for Wildlife in the MLRA

Management activities within the community phase pathways impact wildlife. Community phase, transitional, and restoration pathways are keys to long-term management within each State and between States. Significant inputs must occur to cross the threshold between States (e.g., State 3.0 to 2.0) requiring substantial economic inputs and management (mechanical, reseeding, prescribed fire, woody vegetation removal, grazing intensity, etc.). 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 effects of management on the habitat in comparison to potential short-term negative effects to individuals.

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/Limy Residual), can be located adjacent to ecological sites that support medium to tall shrubs (Loamy Overflow). Conversely, ecological sites that are dominated by short to mid statured grasses (Claypan) can be adjacent to sites with bare soil only supporting minor amounts of short grasses and forbs (Thin Claypan).

Management of these complex ecological sites can provide a heterogeneous or a homogenous landscape. Grassland bird use declines as the plant community transitions to a homogenous state. Managers need to recognize ecological sites and the complexes they occur in to properly manage the landscape. A management regime for one ecological site may negatively impact an adjacent site (e.g., alteration of a grazing regime within a Flat Bottom Wooded Draw 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 capabilities of the site to provide sustainable habitat. Managers also need to consider habitat provided by adjacent/intermingled ecological sites for species with home ranges or life requisites that cannot be provided by one ecological site.

With populations of many grassland-nesting birds in decline, it is important to maintain these ecological sites in a 1.0 Reference State or the 2.0 Native/Invaded. Plant communities, optimal for a guild of grassland species, serve as a population source where the birth rate exceeds mortality. Species may use marginal plant communities; however, these sites may function as a population sink where mortality exceeds the birth rate.

Understanding preferred vegetative stature and sensitivity to woody encroachment is necessary to manage for the specific grassland species. Various grass heights may be used for breeding, nesting, foraging, or winter habitat. While most species use varying heights, many have a preferred vegetative stature height. Please reference the provisional ESD on the North Dakota eFOTG (linked below) for a chart that provides preferred vegetative stature heights and sensitivity to woody vegetation encroachment.

Shallow Sandy Wildlife Habitat Interpretation:

Shallow Sandy ecological sites are droughty sites identified by the presence of coarse or moderately coarse soil textures (fine sandy loamy or coarser) and a shallow depth (10 to 20 inches) to weathered bedrock or hard sandstone bedrock. Shallow Sandy sites support drought-tolerant species but are still productive compared to Sandy sites due to the increase in tall warm-season grasses like prairie sandreed. Shallow Sandy sites support diverse stands of tall- mid- and short warm- and cool-season grasses. Associated ecological sites include Sands, Sandy, Very Shallow, Limy Sands, Steep-Sided Wooded Draw, and Badland. This complex of ecological sites provides habitat for many edge- sensitive grassland bird species.

Shallow Sandy habitat features and components commonly support grassland-nesting birds (notably sharp-tailed grouse nesting, brood cover, and lekking sites) depending upon its plant community state. Insects rely on associated forbs and grasses for survival, serve as food sources for birds and their young and as forage for small and large herbivores.

Shallow Sandy ecological sites generally do not support big sagebrush. Vigor of cool and warm season grasses outcompete big sagebrush. Fire intensity and frequency on this site makes it inappropriate to manage Shallow Sandy sites for big sagebrush.
Shallow Sandy ecological sites may be found in five plant community states (1.0 Reference State, 2.0 Native/Invaded State, 3.0 Invaded State, 4.0 Invaded Conifer State, and 5.0 Go-Back State) within a local landscape. Multiple plant community phases exist within States 1.0 and 2.0. Today, these states occur primarily in response to grazing and drought. Secondary influences include anthropogenic disturbances, black-tailed prairie dogs, and fire.

Because there is no known restoration pathway from State 2.0 to State 1.0, it is important to intensively manage using tools in the community phase pathways of State 1.0 and State 2.0 to prevent further plant community degradation along the T1A Transitional Pathways to Native/Invaded State 2.0. Native wildlife generally benefits from the heterogeneous grasslands, in stature and plant composition, found in States 1.0 and 2.0 which include diverse grass and forb species with varying stature and density. As plant communities degrade and transition to States 3.0 and 4.0, short warm- season grasses, exotic grasses, and Rocky Mountain juniper and/or creeping juniper increase while native grasses and forbs are reduced. This transition results in reduced stature or an increase in woody vegetation.

Success along Restoration Pathway 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 ecological sites within the species’ mobility limits. 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 more easily locate and utilize isolated, restored plant communities.

Plant community phase in the State 3.0 shows increased homogeneity of exotic cool-season grasses with a further reduction in native forbs. Reduced forb diversity limits insect populations, negatively affecting foraging opportunities for grassland-nesting birds. A homogenous grassland landscape does not provide quality escape or winter cover. As a result, many species are not able to meet life requisites within State 3.0. Increased exotic-grass litter can limit access to bare ground by nesting insects.

Shallow Sandy sites can have pockets of (or become dominated by) creeping juniper, Rocky Mountain juniper, and Ponderosa pine. When in high enough density this will impact woody intolerant grassland nesting birds. Ponderosa pine and Rocky Mountain juniper density can create a closed canopy forest.

Management along community phase, transition, or restoration pathways should focus on 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 Prairie Sandreed-Needle and Thread/Sedges:
This plant community offers excellent wildlife habitat; every effort should be made to maintain this ecological site within this community phase. This phase retains high functionality through continued maintenance, 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. These services include putting plant material and dung in contact with mineral soil to be used by low trophic level consumers (such as invertebrate shredders, predators, herbivores, dung beetles and fungal-feeders).

Dakota skippers may prefer this site when host plants, such as little bluestem, are present. Regal fritillary habitat is limited due to Nuttall's violet and prairie violets being uncommon. Monarch butterfly may use flowering forbs on this site; however, few milkweed species are found on this site to support breeding. Bumblebees and other native bees utilize forbs and bare ground for nesting amongst bunchgrasses. Prescribed grazing with adequate recovery periods, as well as prescribed fire to maintain the 1.1 Phase, has little effect on nests of ground-dwelling insects.

Birds: This plant community provides quality nesting, foraging, and escape habitats favored by mid- to tall- grass nesting birds. Several species of grassland birds which prefer mid- to tall-grass stature will use this site. In years with reduced precipitation or drought, nesting recruitment may be compromised. This plant community provides suitable areas for sharp-tailed grouse nesting and brood-rearing habitat. Diverse prey populations provide good hunting opportunities for grassland raptors. Silver sagebrush is incidental to the site and will not provide the necessary life requisites for the Brewer’s sparrow.

Mammals: The diversity of grasses and forbs provide high nutrition levels for small and large herbivores including voles, mice, rodents, jackrabbits, pronghorn, and deer (white-tailed and mule). Short- to moderately-statured grasses provide suitable food and thermal, protective, and escape cover for small herbivores. The composition of mid- to tallgrasses may limit use by the hispid pocket mouse.

Amphibians and Reptiles: This ecological site and associated plant communities provide habitat for smooth green snakes. This ecological site can provide habitat for the northern leopard frog and Great Plains toad dependent on distance to wetland or Riparian Complex ecological sites. Plain’s spadefoot utilizes small ephemeral ponds or associated stream for breeding as well as other habitats offered within this Shallow Sandy ecological site. Vegetation may be too tall and dense for short-horned lizard and sagebrush lizard. Shallow Sandy soils are not conducive to sagebrush lizard.

Fish and Mussels: This ecological site is not directly associated with streams, rivers, or water bodies. Associated ecological sites can receive run-on hydrology from Sallow Sandy sites. Management on these interconnected sites will have limited, secondary effects on aquatic species.

Community Phase 1.2 Needle and Thread–Blue Grama/Sedges:
Long-term drought, with or without heavy continuous grazing and/or annual continuous early spring seasonal grazing, increases the percentage of short cool-season and short warm-season grasses and sedges in this plant community. This plant community becomes dominated by shorter grasses, changing the stature of plant community from mid- to tall plant species to mid- to short-grass species.

Invertebrates: Provides similar life requisites as Community Phase 1.1; however, heavy, continuous grazing or early spring seasonal grazing may negatively impact ground-nesting sites for bumblebees, other native bees, and other ground-nesting insects due to reduction of forbs and timing of forb flowering.

Birds: This plant community provides nesting, foraging, and escape habitats favored by short- to mid- grass nesting birds. A shift to shorter herbaceous plant stature along Community Phase Pathway 1.1A begins to benefit McCown’s longspur, chestnut-collared longspur, horned lark, and burrowing owl. Species preferring midgrass stature will be generally successful with normal to above normal precipitation and a change in management along the 1.2A Community Phase Pathway. In years with reduced precipitation or heavy grazing, nesting recruitment may be compromised for midgrass nesting species. This plant community provides areas suitable for sharp-tailed grouse leks. Limited cover and diverse prey populations provide good hunting opportunity for grassland raptors.

Mammals: Shorter statured grasses reduce thermal, shelter, and escape cover for larger ungulates. Amphibians and Reptiles: Provides similar life requisites as Community Phase 1.1.

Fish and Mussels: Provides similar secondary resources benefits as Community Phase 1.1.

Community Phase 1.3 Little Bluestem-Needle and Thread/Sedges:
Physical soil surface movement associated with the formation of “steps” (minor slumping) through water erosion and deposition in community phase pathway 1.1B cause increased calcium carbonates at the surface giving little bluestem a competitive advantage. This plant community occurs in a mosaic with community phase 1.1 creating a patchwork landscape. Little bluestem dependent species, such as Dakota skipper, can utilize this habitat.

Invertebrates: Provides similar life requisites as Community Phase 1.1; however, the increase in the host plant little bluestem has the potential for increased use by the Dakota skipper.

Birds: Dominated by bunch grasses with short statured sedges, this plant community provides nesting cover for grassland nesting birds that prefer mid- to short- statured nesting cover.

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 secondary resources benefits as Community Phase 1.1.

Community Phase 1.4 Annual Forbs/Bare Ground/Blue Grama/Fetid Marigold (Prairie Dog Town):
This plant community phase is characterized by grazing tolerant sedges, annual forbs, and a higher percentage of bare ground due to the increase in annul forbs. Continued heavy grazing, short-term prairie dog occupation, or a combination of these disturbances will cause a shift to increased annual forbs with a reduction in perennial grasses. Perennial forbs stature and abundance are being replaced by short- statured annual forbs. Bare ground increases and litter amounts and infiltration rates decline; soil surface temperatures increase. Scruffy in appearance, this plant community is resilient, retaining sufficient grazing sensitive native species to return to 1.2 community phase via community phase pathway 1.4A.

Invertebrates: A switch to annual forbs from perennial forbs may have a significant impact to invertebrates, due to the loss of season-long nectar producing plants for pollinators. Annual forbs’ bloom periods are dependent upon climatic conditions, especially precipitation events, and may not provide season-long nectar production. Season-long nectar sources may be found on adjacent plant communities or ecological sites for mobile species. Increased bare ground provides increased nesting sites for bumblebees and other ground nesting insects.

Birds: This short-structured phase, driven by short-term prairie dog occupation, is favored by burrowing owls, chestnut-collared longspur, and McCown’s longspur. Prairie dog towns provide abundant prey populations for grassland raptors. The lack of grass and forb structure limits use by many bird species. Long-term prairie dog occupation following transitional phase pathway T1B leads to the 2.0 State with no known return pathway due to the presence of exotic cool-season grasses. Managing this phase along community phase pathway 1.4A can be an economical and successful method to restore habitat for many grassland nesting birds.

Mammals: Suitable food, thermal, shelter, and escape cover (reduction in litter) for most mammals becomes limited. The loss of diversity of grasses and forbs reduces nutrition levels for small and large herbivores including rodents, white-tailed jackrabbits, and deer. Grazers, such as pronghorn and bison, use prairie dog towns for foraging and loafing. Long-term prairie dog occupation following community phase pathway T1B leads to the 2.0 State with no known return pathway due to the presence of exotic, cool-season grasses. Managing this phase along community phase pathway 1.4A can be an economical and successful method to restore habitat.

Amphibians/Reptiles: Prairie dog towns provide habitat for both amphibians and reptiles. Tiger salamanders, prairie rattlesnakes, plains hog-nosed snake, and other snake species will use the burrow systems of prairie dogs for shelter and denning.

Fish and Mussels: Provides similar secondary resources benefits as Community Phase 1.1.

2.0 Native Invaded State

Community Phase 2.1 Prairie Sandreed-Needle and Thread/Sedges:
This plant community develops through Transition Pathway T1A due to changes in management (chronic season-long or heavy late season grazing or complete rest) and the presence of exotic, cool-season grasses. The threshold between States 1.0 and 2.0 is crossed when Kentucky bluegrass, crested wheatgrass, or other exotic species become established. This plant community phase has a very similar appearance and function to the Reference State of Community 1.1, except it has a minor amount of cool-season exotic grasses and forbs. This phase functions at a high level for native wildlife; therefore, managers should consider the 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 secondary resources benefits as Community Phase 1.1.

Community Phase 2.2 Needle and Thread-Blue Grama/Sedges:
Continuous, heavy season-long grazing or heavy seasonal grazing (with or without drought) along Community Phase Pathway 2.1A, leads to shorter-statured grasses (such as needle and thread, blue grama, and sedges). Dominated by shorter- stature grasses and a loss of nitrogen-fixing or leguminous native forbs, the diversity of this plant community is reduced. Both tap-rooted and fibrous-rooted perennial forbs increase in this phase but remain a minor component. Prescribed grazing (with adequate recovery periods) and return to average precipitation along Community Phase Pathway 2.2A is an efficient, effective method to regain the cool- season grass and forb diversity components in Community Phase 2.1.

Invertebrates: The loss of native forbs and increase in sod-forming grasses limit foraging and nesting sites for all pollinators. Continuous, heavy season-long grazing or heavy seasonal grazing may reduce ground- nesting site availability. Homogeneity of forb species may limit season-long nectar availability.

Birds: Continuous, heavy season-long grazing or heavy seasonal grazing will reduce nesting sites, forage (invertebrates), and cover. A reduced forb component may limit foraging opportunities. Stature is generally short, serving both mid- and shortgrass-nesting birds. Shortgrass-nesting birds favor this phase. Species preferring midgrass stature will be generally successful with normal to above normal precipitation and a change in management along the 2.2A Community Phase Pathway. In years with reduced precipitation or heavy grazing during the nesting season, nesting recruitment may be compromised for species that prefer midgrass nesting. This plant community provides areas suitable for sharp-tailed grouse lek site development. Limited stature and diverse prey populations provide good hunting opportunity for grassland raptors.

Mammals: Suitable food and thermal, protective, and escape cover (reduction in litter) for most mammals becomes limited. The loss of diversity of grasses and forbs reduces nutrition levels for small and large herbivores including voles, mice, rodents, jack rabbits, pronghorn, and deer.

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

Fish and Mussels: Provides similar secondary resources benefits as Community Phase 1.1.

Community Phase 2.3 Little Bluestem-Needle and Thread/Sedges:
Physical soil surface movement associated with the formation of “steps” (minor slumping) through water erosion and deposition in community phase pathway 1.1B cause increased calcium carbonates at the surface giving little bluestem a competitive advantage. This plant community occurs in a mosaic with Community Phase 1.1 creating a patchwork landscape. Little bluestem dependent species, such as Dakota skipper, can utilize this habitat.

Insects: Provides similar life requisites as Community Phase 1.3.

Birds: Provides similar life requisites as Community Phase 1.3.

Mammals: Provides similar life requisites as Community Phase 2.2.

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

Fish and Mussels: Provides similar secondary resources benefits as Community Phase 1.1.

Community Phase 2.4 Annual Forbs/Bare Ground/Blue Grama/Fetid Marigold (Prairie Dog Town:
This plant community is a result of ecological services provided by long-term black-tailed prairie dog occupation coupled with the introduction of exotic cool-season grasses and annual forbs along Community Phase Pathway 2.2C. Removal of black-tailed prairie dogs (via Community Phase Pathway 2.4A) can move this community back to Phase 2.2, but this may require significant management and economic inputs. Black- tailed prairie dogs provide primary ecological services to transition to and maintain Plant Community Phase 2.4.

Invertebrates: The loss of native forb diversity limits use by all pollinators. However, invasive forbs will provide limited seasonal use, dependent upon bloom period. Bare ground, burrows, and short plant stature provide nest sites for bumblebees and other ground-nesting insects. Burrowing owls place dung around their burrow entrance to attract dung beetles and other insects as a food source.

Birds: Burrowing owl and McCown’s longspur rely on the stature and composition this plant community provides. Presence of black-tailed prairie dogs provided diverse prey populations for grassland raptors, including burrowing owls, prairie falcons, and ferruginous hawks. Burrowing owls nest in abandoned prairie dog burrows.

Mammals: Suitable food, thermal, protective, and escape cover (reduction in litter) for most mammals becomes limited. The loss of grass and forb diversity reduces nutrition levels for small and large herbivores including voles, mice, rodents, white-tailed jackrabbits, cottontail rabbits, and deer. Except for black-tailed prairie dogs, this plant community provides little habitat for mid- or small herbivores. Nonetheless, black-tailed prairie dog towns provide important habitat for many mammal species, including small rodents. Grazers, such as pronghorn and bison, use prairie dog towns for foraging and loafing.

Amphibians and Reptiles: Prairie dog towns provide habitat for both amphibians and reptiles. Tiger salamanders, prairie rattlesnakes, plains hog-nosed snake, and other snake species will use the burrow systems of prairie dogs for shelter and denning.

Fish and Mussels: Provides similar secondary resources benefits as Community Phase 1.1.

3.0 Invaded State

Community Phase 3.1 Exotic Cool-Season Grasses/Forbs/Shrubs:
Community Phase Pathway T2A is characterized by complete rest or low intensity (<20% utilization) grazing 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 Kentucky bluegrass and crested wheatgrass. Restoration Pathway R3A requires remnant amounts of native grasses (i.e., prairie sandreed, blue grama, needlegrasses, little bluestem) and forbs (e.g., white sagebrush, silverleaf Indian breadroot, and upright prairie coneflower) with 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. Long-term lack of fire will help this Plant Community Phase transition to 4.1.

Insects: Exotic grasses result from non-use or low intensity (<20% utilization) grazing and 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.

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, limits use by many grassland-nesting birds. Litter accumulations reduce use by chestnut- collared and McCown’s longspurs. Burrowing owls may use the site if sufficient burrows of black-tailed prairie dogs or other burrowing mammals exist. Sharp-tailed grouse leks can be found on this exotic cool-season plant-dominated community; however, winter cover must be provided by adjacent ecological sites or plant communities.

Mammals: Black-tailed prairie dog expansion is possible in this plant community phase except where creeping juniper or soapweed yucca are dominant. This community phase provides foraging habitat for pronghorn and deer. Litter accumulation and shrub cover favors thermal, protective, and escape cover for small rodents. However, reduced availability of native grass seed may reduce food availability for species such as the hispid pocket mouse.

Amphibians and Reptiles: Provides similar secondary resources benefits as Community Phase 1.1.

Fish and Mussels: Provides similar secondary resources benefits as Community Phase 1.1.

4.0 Invaded Conifer State

Community Phase 4.1 Juniper and/or Ponderosa Pine/Shrubs:
Transitional Pathway T2B is characterized long-term lack of fire allowing creeping juniper to dominate. Domination by creeping juniper, Rocky Mountain juniper, or ponderosa pine causes a reduction in forbs, as well as warm- and cool-season native and exotic grasses. Prescribed burning along Restoration Pathway R4A or R4B requires remnant amounts of native warm-season grasses (e.g., blue grama), cool-season grasses (e.g., needlegrasses, western wheatgrass, and prairie Junegrass), and forbs (e.g., silverleaf Indian breadroot, and upright prairie coneflower) to move this plant community to 2.0 or 3.0 States. These remnant populations can only be expressed through frequent prescribed burns and high levels of prescribed grazing management targeting the exotic cool-season grasses. Intensified management along the R4A Pathway will have significant short-term negative impacts on wildlife habitat; however, this is necessary to restore long-term native habitat functions.

Invertebrates: Juniper or ponderosa pine dominance limits use by beneficial insects provided in States 1.0 and 2.0. Creeping juniper does not provide a pollen or nectar source and limits establishment of other flowering forbs or shrubs. The lack of nectar-producing plants limits forage opportunities for bumblebees, regal fritillary, monarch butterfly, and other pollinating species.

Birds: Long-term very light grazing and lack of fire (via Transitional PathwaysT2B and T3A) transitions this ecological site from a grassland dominated site to a juniper and/or ponderosa pine dominated ecological site favoring woodland nesting birds. As canopy cover and/or percent woody cover increase, grassland nesting birds tolerant to woody cover increase, as well as woodland edge bird species. Once juniper or ponderosa pine dominate the site, grassland nesting birds become absent and woodland obligate species flourish dependent on patch size. The woodland patch size is determined by the degree of juniper and pine domination of the site as well as on adjoining ecological sites. In most cases the transition to juniper and pine dominance occurs on adjoining ecological sites prone to the same T2B and T3A pathways as this Shallow Sandy ecological site. Juniper berries provide a food source for many bird species including sharptailed grouse.

Mammals: Conifers provide limited loose bark needed for bat roosting. Small herbivores that can use or tolerate woodland edge (such as least chipmunks, American porcupine, and cotton-tail rabbit) will benefit from this plant community phase. Ponderosa pine provide security and thermal cover used by elk and deer for foraging, loafing, and rearing young-of-the-year. Elk utilize Community Phase 4.1 as a source of cover during daylight hours - only emerging early/late in the day to forage in adjacent grasslands, then returning to the relative security provided by this plant community to ruminate and loaf during daylight hours.

Amphibians/Reptiles: Community Phase 4.1 will not support most of the amphibians and reptiles expected to be present in State 1.0, 2.0 and 3.0.

Fish and Mussels: Provides similar secondary resources benefits as Community Phase 1.1.

5.0 Go-Back State

Community Phase 5.1 Annual/Pioneer Perennial: 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 the presence of insects. Tall stature provided by some weeds, such as marsh elder and ragweed, offer thermal cover and seeds throughout winter.

Successful restoration of native species along Restoration Pathway R5A results in a native grass and forb community in State 2.0, Native/Invaded. Failed restoration to native species through Restoration Pathway R5B results in Invaded State 3.0. Wildlife species response will be dependent upon plant community composition, vegetative stature, patch size, and management activities (such as prescribed grazing, burning, interseeding, haying, or noxious weed control).

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 management on adjacent sites. “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:
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 forage production on this site. This site is dominated by soils in hydrologic group D. Infiltration is typically moderately rapid to rapid; runoff potential for this site varies from low to high depending on 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 example of an exception would be where shortgrasses form a strong sod and dominate the site. Dominance by blue grama, Kentucky bluegrass, and/or smooth bromegrass will result in reduced infiltration and increased runoff. 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

The largest acreage of public land available for recreation in the MLRA is owned and managed by the United States Forest Service (USFS) within the Little Missouri National Grasslands in North Dakota (525,211 acres). These areas are available for hunting, fishing, hiking, camping, horse and bike riding, nature viewing, etc. In addition, the Bureau of Land Management (BLM) manages 30,895 acres in North Dakota and Montana with the same recreational opportunities as the USFS lands. North Dakota and Montana Department of Trust Lands (80,220 acres) provide hunting, bird watching, hiking, and other outdoor recreation opportunities. North Dakota Wildlife Management Areas (3,447 acres) of land managed by the states for wildlife habitat in MLRA 58C.

MLRA 58C is home to the North and South Units of Theodore Roosevelt National Park. The Park encompasses approximately 70,000 acres and welcomes approximately 900,000 visitors annually. 29,920 acres of the park is designated Wilderness Area. The south unit of the park has a 48-mile scenic drive while the north unit has a 28-mile scenic drive. The Badland and associated ecological sites provide the main scenery attraction.

Bird watching: Public and private grasslands within MLRA 58C provide essential habitat for prairie-dependent bird species (such as Sprague's pipits, western meadowlark, and Baird's sparrow) along with some of the larger, showy members of the upland prairie including marbled godwits, upland sandpipers, and willets. The abundance of publicly owned lands (such as Theodore Roosevelt National Park, USFS, North Dakota Department of Trust Lands, BLM, etc.) provide excellent birding opportunities. MLRA 58C is in the Central Flyway.

Hunting/Fishing: MLRA 58C is a fall destination for upland game bird hunters, especially sharp-tailed grouse. This MLRA also provides excellent white-tailed deer, mule deer, pronghorn, elk, coyote, and mountain lion hunting opportunities along with the only bighorn sheep hunting units in the North Dakota. The North Dakota Game and Fish Department manages three man-made fishing lakes within the MLRA. Available species include rainbow and brown trout, bluegill, and largemouth and smallmouth bass.

Camping: Many camping opportunities exist in the MLRA. Modern and primitive camping is available at the Theodore Roosevelt National Park, Sully’s Creek State Park, Little Missouri State Park, Buffalo Gap Campground, BLM land, and the Dakota Prairie National Grasslands. The Sully’s Creek and Little Missouri State Parks are designated horse parks.

Hiking/Biking: Over 150 miles of the May-Daah-Hey Trail provide some of the best single-track trails in the world for biking, hiking, or horseback riding. The International Mountain Biking Association (IMBA) has designated the hiking, biking, and horseback riding trail as EPIC - meaning it’s one of the top mountain biking trails in the United States. The trail has nine fenced campgrounds, each accessible by gravel surfaced roads; they include camping spurs, potable water, hitching rails, picnic tables, fire rings, and accessible toilets. They are spaced about every 20 miles along the trail. The North and South Units of the Theodore Roosevelt National Park provide 38.9 and 49.6 miles, respectively, of hiking trails for walkers, bikers, or horseback riders. The Little Missouri State Park has 45 miles of trails that run through the North Dakota Badlands.

Canoeing: Traversing 274 miles through MLRA 58C, the Little Missouri River provides early spring canoeing and kayaking. The Little Missouri River is the only designated State Scenic River in the MLRA. The river passes through Sully Creek State Park, the Little Missouri National Grassland, and Theodore Roosevelt National Park.
