Koford 178 Cynomys ludovicianus July 12, 1955 Wind Cave N.P., S. Dakota Here a several patches bare ground 5 yds. diam. where they dust (C.L. muds, & more some). Town in wide canyon bottom, sloping S. about 5%. Lygodium in flower, at downstream end, somewhat damper (?), no little C.L. activity, Some Carex penn., Bout. grac. (sedentaries), Ag. sm., & about 5% sage- sworts (at. frig. a graph.). Ag. sm. sedentales 2' high cut by C.L. Much Amaranthus (2 benign kinds; retroflexus common). Andropogon Grows on slope, not lawn flote; decrease under grazing. Upper bast- many town had herd buffalo cows (4 calves) on it, several dusting walkers Solid bright green due mainly to Hedeoma, Verbena bracteosa neeldenge, amaranths, Dyssodia. In low spot some Bout. grac. Few perennials in main part town (what set winter?). One area thick Loppula, now Drying, 6" tall, not kept down by C.L. At edges town at. frig. cut, thin on slopes 1 ft. tall & current. Less thought evidence indicated elimination at. frig. by C.L. on flat. Andropogon also started on slope where at. frig., tall & thick. Ag. sm. present but very sparse our colony. On some walkovers & bare ground C.L. muds, Portulaca (annual succulent), but not apparently eaten. Saw block widow in C.L. hole. Sylvan town. Some priv. now (at least 4) & about 6 grams, in area seen before (except not in E. patina, where no fresh cuttings at. frig.). 1/2 acre dry Loppula 6" tall. On muds. usual: Verbena bracteosa, Amaranthus retroflexus, Dyssodia papposa, Ag. sm. (18" sheizons?). Rather fresh lodger hole at S. edge town; 4-seed apparent old bolder hole in hole. On unused mounds, at. frig., 2 amar- thurs, Lyge Lygod, Plantago, Hedeoma, Verbena bract., Cuphobia. Cut at. frig. to 50' uphill of S.W edge burrows. Amaranthus retro- flexus chief plant on mounds. Parts of town had many solid Schel mounds, perhaps indicates of more recent disturbance of ground. More
