A 2-yr study of livestock/wildlife tracking was conducted on four streams in eastern Oregon. Binomial sampling of tracks proved to be an effective statistical method for monitoring the proportion of samples containing tracks on stream greenlines and testing the observed value against an established standard. Study results indicate that tracks are related to variables outside of the control of livestock grazing management.
