As well as providing a renewable and self-replenishing source of fast grown wood, coppicing generates biodiversity.
Coppicing, or the cutting of trees, floods the woodland floor with light. This allows an abundance of wild flowers to grow, which in turn attract insects, which attract birds, and so on. This creation of meadow land within a wood (for a short period) means there is space for wildlife to feed and breed near to their nests or shelter. As this cleared area re-grows, when the coppiced stool develops, your next harvest will open up another clearing adjacent to it, creating a chain of space for the wildlife now supported by the woodland.
