Data was acquired during aerial surveys conducted by Montana Fish, Wildlife & Parks (FWP) between 1991 and 2003. The aerial surveys were conducted annually to count and classify mule deer in the area. Data are used by Montana Fish, Wildlife & Parks in their management responsibilities to set hunting seasons, determine population trends, and identify critical habitats. Observations were recorded on data forms and locations either plotted on USFS Maps (Deerlodge National Forest) or recorded by specific location.
The data represents winter observations of mule deer. It is not intended to represent overall or annual distribution. Each individual observation represents one or more animals. Density of observations does not necessarily equal density of animals.
