Woodland grazer (4)
I believe the answer is:
deer
'woodland grazer' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for deer that I've seen before include "Antlered mammal" , "The males have antlers" , "Red, roe or fallow" , "Hoofed mammal" , "The - Hunter, 1978 film" .)
