The secrets of the forest
If trees have rings, it’s not because they’re tired. Let’s take a virtual walk into the forest. We will determine the age of several trees and plants (aspen, balsam fir, sequoia and bamboo) by counting their growth rings. We will also study their modes of reproduction by handling the cones of the balsam fir and discussing bamboo rhizomes. We will also experiment on the effects of bark wounds on sap flow and look at examples of tree diseases. A great workshop for allowing new knowledge to take root!
