Koford 280 Cynomys ludovicianus September 25,1955 Theo.Roosevelt N.M.P., N. Dak. Schoellom. & Plantago pennsylv.; different from surrounding area where much Bgr. Bgr generally lacking in lower Badford Creek town in area of abandoned ploughed ground, the Arm common there. September 26,1955 Soil scientist of SCS, Dickinson, told me that in this region prairie dogs mostly on Moreau clay loam. Commonly on "scotland." But on any soil that will' pack, hardly on immature soils, or park or fewer other soil washed down from bluffs. 1) At small town near S.E. Antone, pop- ulation moderate. I saw 15 in W. 1/4, in area 50x50 yds. Less elsewhere. Now seen upslope from road. At roadside slope, many shallow digging for roots. On colony grows mainly Bgr turf 1" tall. Much of it cut at base, about 50% bare ground before cut. No apparent spread of town. At E. side, old widely mound fortheast E., in short grass area, but 5 yds. Eight mid-grass (Bgr-arm) 1" tall & thick, the soil & slope same. No recent eating cottus leaves. (Ernie's shed & saddler, but mice probably ate). Bgr turf areas near colony to E., & downslope to S., but no mimivars. Slope 5-10%, to S. A group old mostly dead Artemisia tridentata shrubs at downslope edge activity; latest 4: Low silver sage stellar (0" tall) cut, probably by C. L. 1) In middle colony, some burrows downslope 10 yds. into Arm & other mid-grass 1" tall & Thick. Three templed rod trails thru, near burrows. Most of these, & some 20 yds. into mid-grass, apparently not currently used. An occasional large Aman. lit. on mound but nearly dead; a few aside, on ground near - food for C.L. Some green leaves remain on Salsify. 3. Fresh appearing dodger dug burrows in W. part colony. A few old mured burrows to W. of W. edge colony. 1) On upslope side of road 8" burrower within 20 yds. road, in one 25
