what are the different ways woodland is sustained part 1
trees are cleared in strips or patches- trees find it easier to grow here, not in a clearing. harvested by coppicing - cutting down trees in a way that lets them grow back.

what are the different ways woodland is sustained part 2
Native tree species tend to be planted rather than non-native, which is better for biodiversity because their presence should help the other tress grow in the area as they have established long-interactions.

planted trees are attached to posts for support, and grown in plstic tubes to stop them being eaten. trees arent planted closely together so they have enough room to grow rather than compete.
