Abstract: Our purpose was to determine whether dispersal of juvenile elk from natal summer ranges (herd segments) contributed to limitation of population size and thereby reduced the need for hunting in Grand Teton National Park. Our results suggested that dispersal out of the Jackson elk herd was not a population-regulating influence and dispersal out of Grand Teton National Park was not a limiting influence on growth of elk numbers in the park. We concluded that at current elk densities, which are artificially maintained by winter feeding, hunting remains a necessary control on elk numbers in Grand Teton National Park.
