Koford 147 Cynomys ludovicianus June 19, 1955 Wind Cave Nat'l Park, S. Dakota. mound flattish & well packed, no C.L. droppings or recent toolings from digging. This apparently den of a badger, for I saw one there 8:40 a.m. to 9:30 a.m. Of about 25 C.L. burrows within 100 yds. Badger, one may have dug badger dug recently, perhaps 4 in last year. Of 60+ burrows examined in Ward C', only about 5 seemed to have been dug out by badger, more recently. (Area X has one badger dug burrow, at least 2 such just W. of Ward A. More fresh.) // Aller - definition "evergrazing" means grazing that changes plant composition! Must separate term from overstocking overutilization. // At SW end of Ward C', much Lappula & Asa. white dogs. Uninvaded area (a few unmowed & partly grown own holes) mostly Mustard (1/2' tall, Asa. 1' tall, Lappula 1' tall, Sphaeralcea 6" tall. However, 150 yds. S W of top C' & across streambed in fall & dog area of about 1 acre (area B) in bottom, about 50 × 75 yds. size. Contains at least 3 gram + 4 junis. Non-1 old badger dug burrow, about 10 obvious by much used. To NW upslope (20%+) nearest currently used burrow 150 yds. distant (= area F). // At 2 p.m., 7 Artibesopa resting at W. end of Ward D. I heard coyote on Ward G. // Found a few stolles of dead Raven (12-18"), some of Potentilla (6"), many of Antennia fragi- side, cut on C.L. term. Also 4" tall Chenopodium (album ?) when thick on Ward B. // On both Wards A & B I found an apparent badger bored hole that had been filled up by C.L., & now tamped with more. On Ward B, 5 apparent badger - bad holes (not recently bored) in drain. 100', & at least 2 others on that ward. On Ward A near stake 1/4 c.f., an old badger bored hole had C.L. scratching around as if to fill it at entrance. June 29, 1955, At 7:25 a.m. I saw 2 badgers in Shattail Canyon lot. Tom near site where we yesterday. They walked close to C.L. burrow showing recent repair, & seemed to look toward a C.L. giving alarm chirps 50 yds.
