Koford Journal July 29, 1955 — Rocky Mtn. Nat'l Park, Colo. ground squirrels, latemias, Peribatran ground squirrels all present in two parks at once. (PER, Weld Co., Colo.) July 21, 1955 Arrived at (PER) colony about 10 a.m. to continue mapping & observing effects of C.L. In NW portion, noted a spreading succulent, near-cactus luit apparently not cacti. Bout. grac. sudetella cut at many sites, allowing determination of limits feeding activity. In quadrats P (‘I-B’-A’), cut to about 20 yds., with 50% E. slope from recently dug burrows. Of recent burrows (May, June) N. of force, some dug no deeper, others dug much deeper than 6/26. Depths & mound sizes (steam, thielinera) noted on overlay map mode. Salsola prin- cipal forb cut, luit Chenop. at lefts, also much cut, & some Am- another retrophiline, Ag. smithii cut when told, & even juncea in wet bottoms (at edge where stand thin). About 20 stolba juncea cut / sq. yds. some sites. On flatted bottom through out colony, where Bout. grac. about 90% of vegetation, much of it cut (seed stolba). (Klipple says seedlings rare & seed crop poor, so perhaps little loss since due to C.L.). In quadrat LA, some cutting throughout patch of Salsola to about 18" tall in mod. dense stand—about 3' lattice—large plots, & Chenop. lept., Loppula, Bout. grac., & other herbs mixed. Cleome & Cirsium 2-3' tall & conspicuous became not cut (toot? stickers?) the adjacent forbs cut. One depressed burrow, showing use, located at base 3' tall cement Cleome, Guttenia & Chrysanthemum about 8" tall & meet the green. One spot (in PA') Allium dug up & root eaten. No Sycophyta or Crot- alea seen, luit Sylligogon common. I flushed 2 from 40 190
