Black-tailed Prairie Dog

_Specimens examined_ (5).--Sec. 25, R. 3 E, T. 22 N, 2; 1-1/2 mi. W

Buffalo, 1; 1/2 mi. W Camp Crook, 3200 ft., 2.

The extensive flatlands of short grasses on relatively deep soils

provide ideal habitat for the black-tailed prairie dog in Harding

County. Visher (1914:89) mentioned extensive colonies along "flats" of

streams and reported one "town" west of the Little Missouri River that

covered several sections and another "on the table of the West Short

Pine Hills." Recently, emphasis on control of numbers of prairie dogs in

the area has reduced many formerly extensive colonies to small, disjunct

units. According to Robert Kriege (personal communication, 1968), a

"town" of approximately 3000 acres, about five miles east of the Little

Missouri River (in R. 2 E, T. 21 N), is the largest remaining in the

county. Thirteen other colonies then known to him ranged in approximate

size from 25 to 300 acres.

White-colored prairie dogs apparently are not uncommon in some areas of

the county and local residents reported to us a number of instances of

sighting such individuals. One "town" located 7-1/2 mi. N and 12 mi. W

Ladner, in the northwestern corner of the county, contained at least six

families of white individuals, congregated together at the edge of the

colony, in the spring of 1968. White prairie dogs also were noted by one

of our field parties in 1963 in a "town" formerly located 7-1/2 mi. W

Buffalo.
