What ever tree calendar they worked with, is now, to us, in a sense irrelevant. The idea of a tree calendar and tree lore however is still very important. The spirit of the old forest is intrinsically linked with bacteria and fungi, these lie waiting underground to nourish, support and co-create with trees. What we need to do is get out there and restore our tree coverage. Only then will the true magic of the trees and the forest become apparent. Most of us won't see this time but we must still collect, plant, nourish and care for the seed of the new forest.
