Koford 179 Cynomys ludovicianus July 12, 1955 Wind Cave N.P., S. Dakota then noted any other sites. Ratibida (an annual) also present. Lee said that denuded ground took 15-60 yrs. to recover native perennial vegetation, coming blocks forth on heavy soils (e.g., sun, one of first to return, formed by heavy soil). July 13, 1955 7/10 a.m., only 6 a.m., & all dogs evidently not out yet. about 14 antelope on W. side, in bottom, apparently resting there. With Lee's Alve studied range in relation C.L., in Shirttail Canyon & on line transect when John King ran one in 1948. Stalkless bull thistles do not see, indicate C.L. effect, for have not stell first year. Several mds.: annuals & rhebionous perennials. Lee says few dogs in Butte Co. when a dark alkali soil. He has hunted C.L. 20 years for sport & has never seen a fawn. In some areas sheep grazing knocks out Bout. grac., rapidly. Maybe C.L. do to, as little or none on campgrounds. Ag. sm., Bout. grac., has seed reproduced primarily. Little Stipa in dog towns, a wedge; they are green early. Hedeoma very common on town but not invidual of mds, it appears. On line transect, over 10-20' across of Buckler encountered, the king did not mention this species on his line. Amaranthus retroflexus & Lierberg brittonii grow very large & spreading on C.L. mounds, as compared to elsewhere. In one area where much Bromus japon., cut, much Ag. sm., left standing as if less cut. Even Hedeoma cut at edge one expects their stand. Ag. sm., plants especially many staked, as compared to where other areas with which Lee familiar - effect of C.L. clipping? Fairly complete klein grasses in areas apparently occupied, so year a two surprised Lee. Plantago common on Ward Bia spinulosa; the common Lappula is hispida, common Hedeoma is hispida.
