Koford Cynomys ludovicianus July 29, 1955 Wind Cave N.P., Hot Custer G., S.Dak. But more where C. l. thicker. (Step loops 1" - 50 loops in 60x60' area around fourth set burrow: Baa 5290, Bgr 26%, Carey 20%, forks 2%). Probably fine C.L. where much Carey in this area. || At E. side Upper Sand. town, fence posts without wire. To E., near A.Sun, 4 some burrows just not currently used. Arm goes to about 25 yds W. of fence, thinning, thin fala only. Slope of colony line about 6%, W. aspect. No Bgrs. in census plot or in most of colony. When burrow E. of fence, much A.Sun (10% of veg.) out of day (need before fala came in?). When burrow stops, Carey's Care increase, slope steepens, socha pretends, pines grow. In census plot I paced distance between absent burrows for 15 spaces; one 7 yds. At an uphill edge col- ony, inside, then A.Sun - Spa mixture, then fence line, then Bgrs - Sam. At S. end colony (slope envious down), A.Sun increases, then taller, then might with Bgrs. An area of Bgrs near bottom at S. end, but no corpses. C.L. was here. || Sylvan town had 4 buck elk feeding in center, diligently. C.L. out 20 yds. from thin, 41 mourning dove. I stayed at colony 1½ hrs. Eventually decided total pop. 9 grain + 7 pairs. (Divided 3-3-1), pairs still easily distinguished by size (= high productivity?). All C.L. in area of 2 A. in center of opening among trees. Slope 10% NE. (This area at bottom R. of aerial photo BNV 134-19, Sep. 19, 1938). ↓ N Stipa vir., Bgr, (any afr.) pines old burr area activity now → old burrows up canyon pine clump Dogs town: we allowed approach to 10 yds.; pairs to 20. (Vegigine feed late in day probably in spite of Kriggs' statements). Two wide at several places of Dip. papp, cutting off part or all plant down, holding + eating stalks leaves from base up. One ate many tips of low lawn. [lot], just holding plant + nibbling tips, not cutting off. this kind feed more pleads
