Second, I compared home range size between source populations and dispersing groups using 2- sample r-tests. Third, I evaluated Euclidean distances between points in associated dispersing group and source populations through a multiple range permuta- tion procedures test, which evaluates whether distri- butions of distances in different groups come from a common probability distribution (Mielke et al. 1976). Fourth, I compared use-area ratios of core areas be- tween dispersing groups and associated source popu- lations to determine if differences existed in degree of concentration of core area use using a 2-sample r-test. The ratio of core to non-core use is important because core areas would be likely to include the most opti- mal habitat within a home range. Therefore I treated the concentration of use in core areas as an index of relative differences between optimal and suboptimal habitats within a home range. Use of Vegetation Commitnities and Production of Forage The types of vegetation communities present on all seasonal ranges of all populations varied, but were simplified for analysis to categories of alpine, grass- forb (meadows). Douglas Fir. Limberpine, Lodgepole Pine, sagebrush. Spruce (subalpine forest), and WTiite- bark Pine. Together, these \egetation communities cov- ered the range of elevations used by all populations in all seasons as well as broadly covering the array of vegetation communities encountered and used by Elk. Comparisons of use of \egetation communities by Elk in source populations, based on locations of animals, to availability of such communities visu
