maturity

The stages in the life cycle of a tree. Young or juvenile trees have not yet reached 1/3 of their expected mature height. Early-mature trees are between 1/3 and 2/3 of expected mature height. Mature trees are close to their full height and crown size, these dimensions being determined by the context. Late-mature trees are still close to their full height while both crown size and main-stem diameter (which is by now large) increase slowly. Senescent trees are in a decline associated with lessening crown volume, so that the crown has large-diameter deadwood including stag-heads.
