Koford 209 Cynomys ludovicianus September 29, 1955 Devil's Tower NE Wyo. W. edge colony Cynomys minor near toward pinyon. When Aristida green + not dense, many plants out to 1" in lean, probably by C.L. I saw an eating seeds from the arms. One rod. had Salsola 2' tall growing on ball of it. She now fell in flatter tough + probably not eaten by C.L., much (saw uncut leaves). / In NW corner of main flat, nr. road, 24 in 1 A. This a weedy area (much Sphaerula) bordering drop 15' to bottom on W. Many bones gone on arm + storm apparently cut, probably much eaten now. / Diggings common on edge mound + on roadbank at many sites, but generally much less than at TRNMP. / I saw some eat dry Polygonum curvularis, cutting at base, picking up, eating from base + also eating leaves (green) without cutting. / Apparently no weedy area sought or preferred to point of eliminating them. Dego. pap. common in only a few sites, soil yards across on this term. Where 24 C.L. in 1 A., dropping average 12/sq. ft. for many sq. yds. / Roadside Melilotus in ditch on bank. I saw 3 C.L. eating leaves. Other dug dam + streets. Plants spreading + about 4-6" tall now. / To N. of road on 5% slope, shrub scrape, prominent red-brown. Fairly quickly replaced by thick Aristida; no intermediate veget. stage. Aristida here due C.L. activity? Population generally low in thick Aristida area - perhaps 4/A - but 10/A when thin + green + some Cynomys mixed; near road (damp slope). (Corn apparently found in whirling under dampa.) Beld pitcher moderately cut by C.L. near Aristida dominant areas. Aristida changes to Assat about 10% slope; with players from Assat (soil texture differs?).
