Koford 121 Cynomy5 ludovicianus May 21, 1955 Medora, N. Dakota Warren Whitman of Dickinson Cyp. Sto. believe range conditions this region not greatly different in past than in present. Clete. Brooks has much info on Indians, bison, bufalo, grazing, & other historical factors this area. May 22, 1955 Light rain & overcast. Visited Big Platon colony in Sec. 2. Saw at least 16 C.L. there. This mainly on long abandoned ploughed ground. Much Taraxacum on colony, & another similar plant. Some dock lights in mounds & some C.L. half block with it. Ground quite undulating, the net slope near 0%. Badger dug hole present. Bob May, ranger, says he has seen badger here in daytime on occasions. Shat Artemisia frigida present, & many 2" stolles cut, apparently lay C.L. Edge this colony 200 yds. from edge plateau, then a drop of about 200' to a town below, to S. Surrounding colony on seed stolles of Art. frig. about 1' high (looking inside colony DS apparently C.L. eat). Tufts of Stipa comata around edges (indicate little grazing). Ant mounds present. A small C.L. burrow under edge of two of these, one still with many ant mounds. Vegetation very flor- igenous. At bare edge saw C.L. mounds, shot Art. frig. theils. Two Around some mounds, Art. frig. & rose to 10' from burrow, then Bromus 6" high dominant. Some Bromus on mounds, & grow- ing much more vigorously than around. Several antilope*, sharp- tailed grouse, seen nearby. In their grass near a bord, runways of a mole. || On Knudson Creek canyon or gentle green grassy slope near bottom there are a few colonies. At one of these, local road was poisoned in 1953, & many C.L. found dead on ground. Adjacent ground has much long leafed sage. Some seen last summer in poising area, but none seen in brief visit today. (Apeiru wells in
