in 2006, many, many acres of the Kaibab Forest was devastated by a lightning-strike fire. We saw lots of burnt stumps and, for some miles, the scenery was one of scorched earth. Apart that is from the regrowth of Quaking Aspens. They were obviously the first tree able to recolonise after the conflagration. It's a fascinating tree and, because I know my readers share my love of botany, here are a few facts to delight and inform you.
One aspen tree is actually only a small part of a larger organism.
A stand or group of aspen trees is considered a singular organism with
the main life force underground in the extensive root system. Before a
single aspen trunk appears above the surface, the root system may lie
dormant for many years until the conditions are just right, including
sufficient sunlight. In a single stand, each tree is a genetic replicate
of the other, hence the name a “clone” of aspens used to describe a
stand.
Older than the massive Sequoias or the biblical Bristlecone Pines, the oldest known aspen clone has lived more than 80,000 years on Utah’s Fishlake National Forest. And that's why it can survive fierce forest fires and spring back to life ahead of anything else. |
