Drive out of wild trees (5)
I believe the answer is:
steer
'drive' is the definition.
(thesaurus)
'wild trees' is the wordplay.
'wild' is an anagram indicator.
'trees' is an anagram of 'STEER'.
'out of' is the link.
(Other definitions for steer that I've seen before include "Guide the bull" , "Guide; bullock" , "cox" , "Guide, control" , "Cattle - guide" .)
