Remove some deciduous trees (4)

I believe the answer is:

oust

'remove' is the definition.
(I know that oust is a more specific form of the action remove)

'some deciduous trees' is the wordplay.
'some' indicates the answer is hidden within the clue (some of the parts of the word are used).
'OUST' is hidden within 'deciduous trees'.

(Other definitions for oust that I've seen before include "Overthrow" , "Remove and replace" , "Unseat" , "Remove or reject from position" , "Put out, say of office" .)

I've seen this clue in The Telegraph.
