Grand Teton National Park Report
Accumulation of data on the distribution, density, movements, activity patterns, and behavior of river otters, primarily on the Snake River, is the goal of this study. Such information has intrinsic value and also should be useful to the National Park Service in enhancing the welfare of this interesting member of the park's fauna.
