This report is dedicated to the memory of our esteemed colleague, Jim Reichel, who had initiated a biological inventory within the study area at the time of his tragic passing. The expertise and interest of U.S. Fish and Wildlife Service staff was integral to this project, which greatly benefited by the coordination and expertise of Mike Rabenberg. It also benefited from discussions and help of the entire Medicine Lake Office. The access permission and kindness of landowners and leasees contacted in this study are acknowledged with gratitude. Special thanks are also extended to all who provided information on the plant life of Sheridan County, or the county in general, including Mike Rabenberg (USFWS), Aldon Joyes, Doug Smith, Cherryl Wagner, Ted Nordhagen, Monica Friedrich (NRCS) and Terry Angvick (Extension Service).

Grank & Reasons: G3 (99-12-06). This small patch type currently has a circumscribed geographic distribution, though its description from Saskatchewan and North Dakota would not be unexpected. Habitats with the potential to support this type appear to be relatively abundant, but the type itself is comparatively uncommon. This types affinity for well-drained benches and gently inclined landforms in a primarily agricultural landscape puts it at a moderate risk for agriculture conversion. Fortunately, this landform also occurs in breakland and badland environments less desirable for agriculture, thus lessening the chances of this uncommon type being converted to agriculture. Its graminoid composition renders it only moderately attractive to cattle, and the scarcity of forbs decrease its value as sheep range. Element Distribution Range: This association is well documented from Montana and Alberta, Canada. The same or a closely analogous type occurs in Wyoming, and some permutation of the type is to be expected in northwestern North Dakota and Saskatchewan.
