Abstract

In the interior of British Columbia, Douglas-fir litterfall is a major source of mule deer winter food. Dawson et al. (1990) found that preference for Douglas-fir foliage was correlated with tree diameter. This study set out to identify the underlying ultimate factors of selection so that wildlife managers might have a wider range of forage enhancement options on mule deer winter range. Such options include, for example, planting, thinning, or fertilizing trees to improve palatability.
