Regrowth is an ancient form of forest management, involving repetitive felling on the same stump (also known as regrowth stool), near ground level, and allowing shoots to regrow from that main stump.
Trees that can be cut down are very important. They are a sustainable source of material, allowing multiple products to be created repeatedly over the life of the tree. They can be grown in different stages, so different sizes are available, which also creates a wide range of ecosystems.
