Do they provide wood for making sets? (7)

I believe the answer is:

forests

I'm a little stuck... Click here to teach me more about this clue!

'do they provide wood' is the definition.
The definition suggests an adverb but the answer is not.

'for making sets?' is the wordplay.
'making' is an anagram indicator.
'sets' anagrammed gives 'ests'.
'for'+'ests'='FORESTS'

Can you help me to learn more?

(Other definitions for forests that I've seen before include "Large, densely-wooded area" , "Large woods" , "Densely wooded areas" , "Woodlands" .)

I've seen this clue in the Evening Standard.
