Douglas-Fir Growth Race
Douglas Fir (Pseudotsuga menziesii)
Douglas fir trees are important in the Pacific Northwest because they provide cultural, environmental and economic resources. Douglas fir trees are widespread and can be found from central British Columbia to southern Mexico, including both interior and coastal populations.
Are trees from Oregon better adapted to future climates in Washington?
Douglas fir are iconic trees of Washington, but how will they favor in future climates?
Adaptation in trees is a slow process and seeds do not move very far naturally. Assisted seed migration may be a helpful method for keeping Douglas-fir populations healthy in changing climate conditions.
The aim of this project is to provide an opportunity to learn more about climate adaptation and explore the genetic diversity of Douglas fir.
Trees from populations adapted to typical climates of Fort Lewis, Washington and the Siskiyou Mountains in Oregon were donated from the Forest Service Northwest Research Station. Together we can monitor and compare the growth of these trees in Washington.
