May 18, 1955 Wind Gve Nat'l Park S.Dak.
Talked with James Cole, Biologist, NPS about prairie dogs here,
He said now few in Shirt-tail Canyon at sets when King studied &
little grass. He said he saw 1 young out. At Nalbesh town, he
said also few dogs, 4 grass coming back in town. He told me
that one at Theodore Roosevelt park he saw a lodge & a coyote
hunting prairie dogs together, as if to guard 2 holes of a burrow.
He is not at all sure that livin + antelope from C.L. towns because
of food (or?) there, or least King has suggested.
May 19, 1955 Visited several prairie dog towns in park with Cole.
At Shirttail colony, found old marks put out by King. Area he
studied stood out as bare ground away surrounding greenery, &
this seemed to be only about 2 dogs / A thru. Cole said that in
1947 there was more an area where King worked. Cole had also thought
there would be no expansion upslope to W., when much Aristida, but
such expansion had occurred. Cole correlated that oldest part town
at W. end, upstream. We saw 8 T. Antilocapra on a well-wooded
section of the town. One abandoned burrow had conspicuous growth
of Bromus on a 5' around mound. A slope to N. of stream had
burrows on rather steep ground; inhabited looking holes to 22%.
slope, & older, not recently used, to 31%. One pocket inside lay
now recently (due rain?). Many showed evidence scratching
south toward burrow as if to build up mound. Very pronounced abundance fuls on heavily used part of colony. A go
stand grass on part of bottom where Cole said once almost
bare of grass, on a rather old part of colony. || At Nalbesh Dam
colony, almost no dogs & good stand of grass for 100 yards
beyond the display sign, where ground is flattest. Out here I saw
