Ecoterrorists protecting doves' home (4)
I believe the answer is:
'doves' home' is the definition.
(I've seen this in another clue)
'ecoterrorists protecting' is the wordplay.
'protecting' indicates the answer is hidden within the clue.
'COTE' is hidden in the letters of 'ecoterrorists'.
(Other definitions for cote that I've seen before include "Shelter for pigeons" , "Home for doves" , "Small shelter, for doves say" , "Place for doves" , "Pigeon shelter" .)
