Montana Field Guide. General Description. The Western Great Plains Badlands ecological system occurs within the mixed grass and sand prairie regions of eastern and southeastern Montana, where the land lies well above or below its local base level, shaped by the carving action of streams, erosion, and erosible parent material. It is easily recognized by its rugged, eroded, and often colorful land formations, and the relative absence of vegetative cover. In those areas with vegetation, species can include scattered individuals of many dryland shrubs or herbaceous taxa, including curlycup gumweed (Grindelia squarrosa), threadleaf snakeweed (Gutierrezia sarothrae) (especially with overuse and grazing), greasewood (Sarcobatus vermiculatus), Gardner.
Patches of sagebrush (Artemisia spp.) can also occur. Precipitation ranges from 7 to 1. The sedimentary parent material of exposed rocks and the resultant eroded clay soils are derived from Cretaceous sea beds and are often fossil- rich. Dominant soil types are in the order Entisols. Based on surveys done since 2006 by the University of Hawai United States Forest Service National Lichens & Air Quality Database and Clearinghouse. These mineral soils are found primarily on uplands, slopes, and creek bottoms and are easily erodible. The growing season is short, averaging 1. Canadian border to 1. Wyoming border. Diagnostic Characteristics. Highly eroded landforms; less than 1. Similar Systems. Range. This system is scattered throughout eastern Montana where eroded landscapes limit the ability of vegetation to thrive. This system is well represented in Makoshika State Park near Glendive, in the Terry Badlands north of the Yellowstone River, and at scattered locations along tributaries of the Missouri river in the northwestern Great Plains. Soils are extremely dry and easily erodible consolidated clayey soils with bands of sandstone or isolated consolidates. In these arid to semi- arid climates, infrequent but torrential rains cause rapid erosion, leaving a highly dissected landscape with a complex dendritic drainage pattern. Vegetation. Vegetation within the Badlands region is sparse. Typically less than 2. In northeastern Montana, vegetation cover is at the higher end, but in southeastern Montana, portions of this system may have little to no vegetation. Vegetation is typically a mixture of shrub and herbaceous species. AUTHORSHIP AND CITATION: Innes, Robin J. Toxicodendron radicans, T. In: Fire Effects Information System, . Department of Agriculture.Common plant associations include greasewood (Sarcobatus vermiculatus) - Gardner. Graminoid cover is very sparse, but may include western wheatgrass (Pascopyrum smithii), bluebunch wheatgrass (Pseudoroegneria spicata), and Indian ricegrass (Achnatherum hymenoides). Common forbs include few- flowered buckwheat (Eriogonum pauciflorum), threadleaf snakweed(Gutierrezia sarothrae), Hooker. Other shrubs that may be present include Wyoming big sagebrush (Artemisia tridentata ssp. Typically soils of the badlands ecosystem are easily erodible consolidated clay or sandstone outcrops. They may also occur on shallow Entisols, with parent material and/or bedrock formation close to the surface. These highly erodible soils can also be strongly influenced by infrequent but often torrential rains. Management. Because of the erodible soils, this system is easily damaged by off- road vehicle use, which has become increasingly widespread in southeastern Montana. Hutto and Young 1.
