Coppicing is one of the only land based management systems where human beings are part of the system and helps to increase bio-diversity. By cutting the trees in the dormant winter season, they re-grow from the stump in spring and the coppicing process allows light to the forest floor which allows woodland flowers to grow which in turn feed caterpillars of butterflies. The wood can be used for craft work and building and can be cut again and again. When coppicing stops, the light can not reach the forest floor, the woodland flowers decrease and with them the butterflies.
