Show Summary Details


In 1999, a CNN story that focused on animals in Grand Teton reported that mothers and calves were thriving, but unexpectedly, the number of calves was relatively low. The recent decline dropped the Jackson Hole moose population to the bottom tenth to fifteenth percentile in North America. A second marker of fecundity was also low. Like deer, moose have the capacity to produce twins, an event which occurs only when mothers are healthy with much body fat. Alarmingly, twinning rates in Teton moose had also diminished. This chapter describes the author's efforts to gather data on calf survival with and without mothers, in order to offer information about juvenile survival that would inform hunting policies.
