Title: Will climate change affect biodiversity in pacific northwest forests

Technical Report ·
OSTI ID:6575927

Global climate change could have significant consequences for biological diversity in Pacific Northwest (PNW) forested ecosystems, particularly in areas already threatened by anthropogenic activities and the resultant habitat modification and fragmentation. The forests of the Pacific Northwest have a high biological diversity, not only in terms of tree species, but also in terms of herbs, bryophytes and hepatophytes, algae, fungi, protist, bacteria, and many groups of vertebrates and invertebrates. Global circulation and vegetation model projections of global climate change effects on PNW forests include reductions in species diversity in low elevation forests as well as elevational and latitudinal shifts in species ranges. As species are most likely to be stressed at the edges of their ranges, plant and animal species with low mobility, or those that are prevented from migrating by lack of habitat corridors, may become regionally extinct. Endangered species with limited distribution may be especially vulnerable to shifts in habitat conditions.
