Understanding the effects of climatic change on mountain forests, where snowpacks and short growing seasons limit tree establishment and growth, is a key concern for both ecologists and foresters. We quantified associations between climatic and biophysical variables and individual conifer species distributions in mountain forests
with generalized linear models. For the majority of species, a unimodal response to moisture and temperature gradients was evident, suggesting that an environmental niche can be identified. Species known to respond to limiting factors in the abiotic
environment showed the strongest associations with predictor variables.
