Koford Cynomyx lodovicianus July 26,1955 Wind Cave N.P., S. Dakota ripe Aristida fendlera seeds from stalks with teeth; this vigor one for 2 min. (until disturbed by me). Also it grasped green stalk allionia albida & nibbled at it, 4 ate at plant of Chenopodium leptos, not cutting it down. // Saw 2 juncs. feed just inside SW part Ward A; apparently part of 5 juncs. adjacent. // I repeated built transects of king on Ward A. These illustrate definite & substantial reduction of Bja at periphery! Dails & slopes too heterogeneous for diagrammatic variation of vegetation to show up. Too bad vegetational work was not done on more uniform sites. // Set 15 saprophots, oat lost, along S. side Ward A (line g 1h) to see if many rodents present. Probably few; I saw no sign. July 27,1955. In 200'X200' area Ward A (5E quadrant counted was Nf on King grid), counted 54 burrows. Probably prairie dog, not at all often a certain density achieved. Many of them not used now. Much lower density than Devils Tower. // Ward C', down canyon from road about 100 yds., A.saw 10-50% of veg. Bgr. lepturus 30 yds. S. of road & statin 30 yds. from edge Bja at S. end colony. (Bhr. C.L. area S. of road much Lappa. red., Sphaerula, but little Verb. br., Deps. rap., (Ned. hisp.) 30 yds S. road, 30' for E. of perch in bottom, (Ned. hisp., Sphaer. soc., Bgr. A.saw, Lap. red., Verb. br. mitten. // at one edge Bja (thick), Am., Caus., Sphaerula mainly, at another site, A.saw, Lap. red., (Ned. hisp.) Ambrosia (or Plant. pursh.). Diff. because soil variable probably. Many Plantago purshii dry plants lying on ground, roots missing; doubtless C.L. (wore), Lappula & Verberg bracteosa (green, some in flower) not cut. // at extreme S. end of C', minorita C.L., activity is Verb. br., Sph. soc., Am. Ale, 59% A.saw (no other grasses), but Pines (at supply Ca?) present & +50 200
