Study Projects Massive Shifts Across West In Tree Ranges, Forest vs. High Desert Ecosystems

EDIT

Among the findings:

Some of the greatest shifts in tree species are expected to occur at the northern and southern extremes - British Columbia and Alberta in the north and California in the south. Large declines are expected in lodgepole pine and Engelmann spruce, and more temperate species like Douglas-fir and western hemlock expanding to help fill the void.

Wilderness areas are among those at greatest risk for change. They will probably be the first to experience major species shifts. Some of the wetter and milder parts of Western Oregon and Washington will face less overall species change than parts featuring a harsher, more limiting climate.

More than half of the evergreen species are experiencing a significant decrease in their competitiveness in six eco-regions. In conjunction with that, conditions have become more favorable for insect and disease outbreaks.

Warming will encourage growth at higher elevations and latitudes, and increased drought at lower elevations and latitudes. Fire frequency will continue to increase across the West, and any tree species lacking drought resistance will face special challenges.

would be heartbroken. He knew every last tree species in western forests by name, and all their minute identifying characteristics and growth habits, and how they fit into the ecosystem.

change it would be helpful to know about specific areas and trees. Not to mention domestic trees that provide food. We are planting apple trees, chestnut trees and black walnut trees and it would help if the forestry would be working on this also.
