Trees Migrating North Due to Warming

National Geographic – In a paper appearing this month in the journal Forest Ecology and Management, the study authors documented the northward march of 40 major tree species over 30 eastern states based on the distribution of seedlings versus mature trees. Previous studies of plant migrations had been done using only computer simulations, or they focused on how some species are climbing up hills and mountains, said co-author Chris Oswalt, of the Forest Service’s Southern Research Station in Knoxville, Tennessee. By contrast, the new study looked at movement based on latitude, using a sampling of the forest service’s most recent ground-based data.
