Abandon bushy area (5)
I believe the answer is:
scrub
I believe this clue is a double definition.
'abandon' is the first definition.
(thesaurus)
'bushy area' is the second definition.
(Other definitions for scrub that I've seen before include "Wash the stunted shrub?" , "Vegetation consisting of stunted trees or bushes" , "Abandon" , "Rub hard - low vegetation" , "Scour; cancel" .)
