Small grove (5)
I believe the answer is:
copse
'small grove' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for copse that I've seen before include "Clump of small trees for regular cropping" , "Scope for a small wood" , "A little wood" , "Stand of trees" , "Piece of managed woodland" .)
