Abstract: The contributions of elk (Cervus elaphus) densities, weather conditions, and supplemental feeding to birth weights, birthdates and weight gains of neonatal elk were investigated. Study was conducted during 1978-92 in the Jackson elk herd unit, which encompassed an area in the Snake River watershed of northwest Wyoming. Birth weights and neonatal growth rates are reported for 7 cohorts of elk calves. Calf survival was related to cohort birth weight. Variation in developmental traits was not related to supplemental feeding of their mothers or to elk densities, but rather to winter and spring weather conditions when calves were in utero. Investigates the early development of supplementally fed, free-ranging elk. Elk densities; Weight gains of neonatal elk; Duration of supplemental feeding; Correlation between winter survival and cohort birth weight.
