Juvenile survival and population regulation of the Jackson elk herd
Article Abstract:
The migratory Jackson Elk Herd's population has grown from some 8,000 individuals in 1984 to over 16,000 individuals in 1997, prompting concern over management policies. Some members of the herd spend summer in Grand Teton National Park (GTNP) where hunting has controlled population size. A new study investigates survival rates of juvenile elk in the GTNP which are fed in winter and compares them with those that are not fed. No significant differences are found in the processes regulating numbers of elk occupying summer ranges within or outside GTNP. It is suggested that more female harvesting and less supplemental feeding would stem the growth of the Jackson herd.

Early development of supplementally fed, free-ranging elk
Article Abstract:
A study designed to show the effect of supplementary feeding on new-born elk calves in a free-ranging herd is presented. Factors considered in the study include environmental conditions and elk density. The research shows that supplemental feeding had no obvious effect on birth weight, which varied depending upon population densities and weather conditions. Winter feeding pregnant dams may increase milk yield and produce weight gains in calves during their first week of life.
