Abstract:

For many years the condition of the mountain sheep in Yellowstone National Park has not been favorable. Although the sheep have been rigidly protected, and their natural enemies have been reduced in numbers in the park, the estimates of their numbers have continuously fluctuated about 200. This static condition cannot well be due to dearth of range, for Bailey suggested that there may be range in the park for 2000 animals without encroachment on that of other game animals. With the object in view of attempting to discover the factors which are affecting the mountain sheep adversely, studies have been carried on under the direction of the Wildlife Division of the National Park Service. These studies have continued for nearly a year now, and during their prosecution a considerable amount of biological data has accrued. The purpose of this paper is to present some of these data, together with some conclusions which have been reached.
