|Abstract: ||Techniques for studying dynamics of woody browse are largely based on destructive sampling (Telfer 1972, Pease et al. 1979, Keith et al. 1984). This is inefficient because of the high variance among samples, and thus large sample sizes are needed to produce narrow confidence intervals. This type of sampling cannot be used for a long-term study. We describe a nondestructive photographic technique that allows us to estimate growth and mortality of woody twigs browsed by snowshoe hares (Lepus americanus).|
