STUDY AREACuster National Forest -Ashland District is located on the most rugged breaks and ridges between the Powder and Tongue River valleys, 5 miles east of Ashland and 42 miles west of Broadus, in Rosebud and Powder River counties. Its outline has an irregular "J" shape which curves inward along Otter Creek, extending about 41 miles north-south and up to 3 1 miles east-west ( Figure 1). The highly-dissected terrain drains in all directions, with the largest watercourses feeding into the Tongue River. Rolling uplands are broken by complex ridge systems, with particularly well-developed badlands topography at the southeast and west areas. The surface geology throughout is composed solely of the Tongue River Member of the Fort Union Formation, which consists of shallow marine sedimentary deposits from the Cretaceous and Tertiary Periods. Despite the uniform historical geology, the topography and stratigraphy are decidedly heterogeneous. The highly-dissected terrain is carved by water erosion. The horizontally-bedded outcrops include soft sandstones, silty sandstones, clayey shales and lignite. Areas with burnt lignite have baked and oxidized adjacent beds to produce brittle, erosion-resistant porcelainite (Warren 1959). Aster porteri Elyhordeum x moiitanse Elymus ambiguus Five more species collections are labeled with names that have no published synonymy in Kartesz (1994). They, too, warrant review and verification by taxonomic researchers. Anaphalis subalpina Astragalus hylophilus Lupinus pseudoparvi/Iorus Solidago concinna Tradescantia larimiensis species, collections were made and identifications finalized at the Rocky Mountain Herbarium, University of Wyoming (Laramie), or at Montana herbaria (Montana State University, andUniversity of Montana). Collections were also made of species for which the sighting represented a significant range extension based on distribution information in Dorn (1984). All specimens collected are deposited at Montana State University (MONT), with duplicates at the University of Montana (MONTU) and the U.S. Forest Service Regional Missoula Resource Center Herbarium (MRC). All vascular plants encountered at the appropriate mature phenological stage were id...
