One of the realities of rapid climate change is that environmental conditions are changing so fast that many species cannot migrate or adapt quickly enough to keep up with them. This problem is especially present for some of my favorite organisms: trees. Trees, of course, can only move as seeds and their generally long generation times mean that evolution moves at the pace of, well, a tree.
This problem has many ecologists and conservation biologists considering rather extreme measures: helping organisms move around to keep up with climate change. Of course, this sort of action has risks involved, so there is a robust debate going on in scientific and management circles. This post, from the Early Career Ecologists blog, does a great job of laying out the basics of assisted migration.
Trees on the move?! I know you’re thinking, “Come on, Sarah. Trees can’t move.” And, generally, you would be correct in that statement. Tree species are now, however, in a position where movement may be necessary for survival under changing climatic conditions. How trees will move is under debate within the ecological community, but why trees will move is accepted as a survival strategy related to the adaptation of species.
