Koford 172 Cynomys ludovicianus July 6, 1955 N. of Waverly, Colorado. 6 ft. apart, every bush had 1/2 to 2/3 of shoots cut, lying then on shrubs. Found a large jive, dead on mound. No evidence shooting or eating hay remainder, Mr. Fli Colling, Colo. July 7, 1955 at Spring Canyon Dam colony from 10-11:30 a.m. Counted 17, 6 living jivers (perhaps not all out). Two seen at 5.4 W. extreme location when seen early this year on occasion (or if recent spreading). Limits activity apparent for plants cut (Same N+S. of fence, tho no grazing to N.). Male overlay map showing limits & locations C.L. seen. Populatiori settled still. No new shallow burrows apparent (old available). At NW part, many steller Bant. grew. cut - to 8/ag. ft. - 4 lying on ground. Salsola, Carela also cut. Yellowish area on slopes around dry pond due mainly to drying Riddles (heads present, stelka 3-4" tall, now seen cut). NW section has been rehabilitated, apparently, since my tropping, SW N central part, Brown, Nordrum, does not, but apparently not strictly. There grasses in patches, not large solid stands. Saw a baldy Sylindigun with old C.L. hole at edge dry pond (a pile of Anthuin burns just outside entrance, Salsola cut adjacent). Patchers of Salsola of a few ag. ft. almost completely cut down in N central part. No evidence activity N. of # 24; fairly solid 4" Salsola that sector, S. of E-W fence, activity on slope of E. side only to about 5% grade. One seen at 5. pt. of colony limit of where any seen early this year, 4 possibly digging of burrows to S. of this [or reverse slope]. One seen also at central W. aptinity where a Sylindigun was trapped when C.L. seen. July 9, 1956. Took photos cut plants at Spring Can Dam colony.
