Koford Cynomys ludovicianus August 19, 1955. (CPER, weld G, G6). Continued over-grazing here reduces an desirable midgrass (Stipa com, Aem), makes Bgrs form sod instead of having bunch-groce form, then Bgrs root crown breaker down. Bde minimus at first because Bgrs favored preferred by cattle & eaten once in spring (initial period for plant). // I saw a Buteos regalis perched on fencepost near 203 mark at 9:30 a.m. One C.L. on mound 50 yds. Distant but appears not giving alarm. In census area II, counted 5 (3 farthest SE apparent jwrs.; 2 at farthest lurrar). (None at C z in B'M when I shot recently). One trapped (q 13 9) at center in N.W. corner of A'O.
