Koford 182 Cynomys ludovicianus July 15, 1955 Devil's Tower, Wyoming On dog town line, many now perennial forbs than on skirt Tail town, it seemed. Lee Allis told me that an area of mixed prairie in S. Dakota, deliberate overgrazing by cattle for many years, a resultant vegetation mostly Buckler, with some Aem. + other grasses, but no forbs. The stand of Aristida longipes now on dog town line was more than Lee had ever seen in S. Dakota. Chipp plant or wounds here: Polygonum aviculare; then over- author blitida + pasciugana, Antirrhinum artemisiifolia, Ery- trum canadense, Plantago spinulosa, Dalea heli-tenuiflora, of annual forbs; Lygodium, Melilotus, Amorpha, Dalea rigidum, Sphairaeae roscensia, of perennial forbs. Many kinds of tall plants cut: conspicuously Bromus juncea, to 1/2" stem + 3' high, which sometime grows next to wounds. Needatelle Plantago pennsii cut much same sites, & P. spinulosa. at E. and much cutting of Symphoricarpos & Artemisia can. Much Art. gnaphalodes cut several sites. One area much cutting next to a perennial of Euphorbia 12" tall, but little of that cut, (corncut juice?). Fruits of Astroglotis lusculata + others appear ently not eating the succulent, at one site at W. and 2-3 tall Heliantus felled. Shirttail C., S. Dakota July 19, 1955 I stopped an allg about 100 yds.
