Koford Cynomys ludovicianus September 18, 1955 Nr. Ft. Collins, Colo. now, Sha 95% of green veg. (few other weeds); dry barley had heads sweeten, but oat heads apparently eaten. Some oats (raw seedstalks) green leaves, not low, spreading. Some shallow diggings. Sha still green, often looks dense stand, but no fresh cuttings found. Many green leave oats still within; Polyg. avic. grass (all green), green Sha, anying Convolvulus, 5' burnow. Tracer, Chenop. will., Sal. pistig. in stubble. In a low pile of boulders, two burnows started are 10" deep going between two boulders 3"-4" apart (boulders 10-12" diam., 1 hoy- per-thick). Several burnows new since last rain. Pasa not not cut, no fruits eaten. Out green oats at mouth some burn- ows; eaten to node. Culms of oats raw (pulled by C.L.?). Polyg. avic. may have had leaves eaten, so some missing (plot in flann). In old stubble area many Mbs. have new constructing, so still much activity. One strip of Sha (+ dry barley + green oats) 100' wide separator opening around two groups of burnows (veg. 1½-2' tall). // She area of milo planting to W., some fresh cut near base, apparently grain not test- net of er from fallen stalks. Some erect stalks brown now. Much Aman. lilit. grows same area. // She unfallowed zone, much Sha 1' tall had been cut (now dry) at C.L. side of dense stand Sha. Half of green shoots, including flower heads, of Chenop. thamn. bunch had been cut, so most bunch <1' tall (recent cutting). // At N. side milo field too, many green stalks cut at height 3"-8". Some Cuph. marginata also cut this site, about same no. burnows used in milo area here as before. Possibly some shooting C.L. here lately, car trocks, targets. // Visited Dec. 3 horse pasture.
