Coppicing is a woodland management practice which can be dated back to Neolithic times. Trees are repeatedly felled at the base and allowed to regrow, to provide a sustainable supply of timber. They have developed root systems and can regrow quickly. This mimics their natural practice of retrenching, which they do to extend their lifespan. At the same time, greater amounts of light can reach the ground, allowing other species to grow there.
Not for the first time, I reflect that we have a great deal to learn from trees. Time to retrench.
