Get rid of brushwood (5)

I believe the answer is:

scrub

I believe this clue is a double definition.

'get rid of' is the first definition.
(scrub can mean to cancel or erase)

'brushwood' is the second definition.
(both can mean vegetation)

(Other definitions for scrub that I've seen before include "Brush, in two senses" , "clean-up" , "Drop" , "Cancel (colloq)" , "Rub hard with a brush" .)

I've seen this clue in The Times.
