Douglas-fir (Pseudotsuga menziesii) is a commercially important conifer in British Columbia and it is one of the province?s most genetically diverse tree species (3, 26), spanning climatic conditions ranging from semi-arid habitats where it is a climax species occurring in uneven aged stands to wet interior rainforests where it is a long-lived seral component in more even-aged stands with a mixture of other species. Characterizing changes in tree population sensitivity to climate variation across the range of conditions where Douglas fir occurs in B.C. will help to predict their future competitive abilities, productivities, and local abundances. Their sensitivities will likely vary among populations adapted to different climates, and population responses may be particularly pronounced at their climatic limits in B.C.?s northern interior (13).
