Increase radio collared bison to 20

Bison live in small groups of up to 30 animals. The larger groups consist of females and their calves; males occur in smaller groups or as individuals. To count the herd, it is necessary to locate as many of the groups as possible and it is most efficient to do this by putting radio collars on females of different groups. At the present population size, at least 20 collars are required to make sure that most of the bison are located for the count. By the beginning of this plan (June 1998) there will be six to eight bison already with radio collars.
