Koford Cynomyx ludovicianus July 20,1955 Philip, S. Dak. Life on plains (Nelroba earlier); an oldtimers much in field. He believed he had seen much destruction vegetation than accutilization by stock, (On sandhills, one big blueston bottom, little blueston slopes; now gone. : Streamside shrubbing gone.). He believed much of prairie was that stock could be moved out & in easily, as avenue during & after drought, while in early days drought caused long reduction in herds. (His parents lamented when they had to haul water 10 miles). Zimmerman regretted poisoning of coyote, from his dog. He knew of no C.L. in Washburn County. Formerly abundant; custom extended several miles. Big reduction campaign about 2 years ago.// I talked with Don Thompson (captained ferret 1953), enthusiastic prairie dog shooter. He would rather shoot C.L. than antelope. Sometimes shot close to 100 in day for sport. We & others knew of towns (such as near Cottonwood) not for district, & they would shoot there occasionally, keeping prairie dog population down but leaving sufficient for reproduction. I asked about trapping C.L., so he wanted to establish colony close to Philip, for shooting. He very wary about divulging locations towns for fear someone would poison them. Strong for prairie dog conservation; He thought reproduction splendid on site this year; 6 to 8 on a mound. In one pasture where mostly short grass but little grazing, he thought C.L. especially fat now. Wind Cave Nat'l Park, S. Dak. July 29/1955 Norbeck Dam colony. No C.L. about 80 yds. n.e.lim to W. of display sign, & about 80 % of veg. thus A.S.M. Apparently ground too wet at initial time yrs. (a snow stayed), this being flattened part colony. 100yds. E. of highway (85A) on this town, saw new burrows on slope when veg. in short but continuous Bgvs-Bda. To W. of sign, much Arm for about 150 yds., then slope steeper & Bda starts. Buffalo wallows--some have a open vegetation. C.L. burrow at edge./ Wallows open vegetation; & allow invasion
