Koford 171 Cynomys ludovicianus July 6, 1955. N. of Waverly, Colorado their peripheral C.L. burrows. No shallow peripheral burrow found. // Burial: expansion of colony may depend on population in relation to carrying capacity, not to on certain absolute no. of C.L. // Burrows up to 4/sq.ft. of cut down asidestalks of sq. sm., when mixed with green Salsolea, 70% ground bare. // In central area of town, a long raised patio running S. from hill, Cinetia dominant (2-4' apart, 4" tall), 90% ground bare, some sq. sm.; but for burrows a C.L. (far from lower damper drawn ?); 4 for food diggings. // Yellow flowered Eryngium, flower stalk cut or left, leaves not cut, at 3-5" above ground, all 3 main stalks cut, 4 another cut likewise, both 5' from burrows. // In NW part colony, new burrows 6" deep at base Atriplex with cut tops; Two other new near bore Quercus plants, another new 10" deep in shale slope, slobs to 3"x4"x3/6". // Streamlet that when overcart, hot, & humid, relatively few C.L. out. No carnivore sign & no rodent snaker seen. (Predator control sign on some post). Atriplex may be eaten or principally base of new growth coter, this base being about 10" above ground. // At its S. edge hill, activity on 7% slope, 4 many Atriplex cuttings. // About 3/4 for several across SW.E. slope (59%) in NE part colony, where Cinetia dominant, 6" tall, 5-10' distant, Sparse sq. sm., Sphacelung low Chrysotamnus, lettuce, 4 90% bare ground. // In general Cinetia not cut, but at 1 site north of a slump cut. Yellow Eryngium also cut. She needs much Salsolea to 8" high, but apparently not cut. // Note: Burrows seem to be often located in slopes, leading out of swales. New burrows 10" deep in this NE part. In one area 50' distant, Atriplex bunches 3 to
