Reheats damaged part of wood? (3,4)

I believe the answer is:

ash tree

'part of wood?' is the definition.
(a single tree in a forest or wood)

'reheats damaged' is the wordplay.
'damaged' indicates an anagram.
'reheats' is an anagram of 'ASH TREE'.

(Another definition for ash tree that I've seen is " A big plant".)

I've seen this clue in The Guardian.
