Combustion is a chemical change, so the burning of a tree will be a chemical change.
burning of tree or wood is an irreversible chemical change
well its both because...it's a chemical change because when the tree is burning it's letting oxygen and carbon oxide in the air. It's also a physical change because if that tree is sharing roots with another tree that other tree root will become damaged and will sooner or later will be dry rotted and the tree will fall over(it can also damage the grass around it).
Cutting a tree is a physical change. To release the carbon, there has to be a chemical change. Burning or rotting will release the carbon.
