Koford 174 Cynomys ludovicianus July 9, 1955. Larmer 6, Colo. when edge of crater mound broken out, scratchings to 6' extent on that side only, apparently to repair damage, + much Muhl. torn, torn up in process. Browse plants may be as important as meadow to prairie dog, think so. We visited Wellington colony. Given Kochia apparently favorite food(?) or much eat. Distibbli apparently cut in small amount, 4 on lumaw in it with trail thru about 5 yds. 5' tall rather than Distibbli. On horse pasturing, on apparently new lumaw was 35' out in Distibbli towards Typha, when Distibbli not too thick, + some sedge (Z x-set) about 1 1/2' tall near site cut, possibly by C.L. On colony Dam thought C.L. fairly surely keeping the Artriples & Chupston- ner to a few inches height (the perhaps did not originally reduce height shrubs), + keeping Kochia from growing tall (no tall old growth when broken thick). Apparently little grain now being fed left to birds on area, at some line to horse pasturing very little difference in composition, + courage vegetation on 2 sides, the much less browse in horse pasturing. Don told me that Sand Dropseed greass for grumpy birds loses all year, thus possibility for winter food. Cordia, eaten by C.L., not eaten by livestock. July 10, 1955 To Wind Cave, S. Dakota About 7 mi. N. of Red Bird, N. of Rush, wyo, saw apparent 3 in gun dutton to E. of highway 85. Arrived Shintail Canyon late after- noon. First impressions: dog towns all solid bright green with folks, no appearance lawn-like. Browse headed out now + dry appearing. On Ward 104 some other sites, Stichoced (Leyopala) dry, +
