A land's converted to wood (6)
I believe the answer is:
sandal
'to wood' is the definition.
(I've seen this before)
'a land's converted' is the wordplay.
'converted' indicates anagramming the letters.
'a'+'lands'='alands'
'alands' anagrammed gives 'SANDAL'.
(Other definitions for sandal that I've seen before include "Item of footwear" , "One can go on foot" , "Light open-toed shoe" , "Informal shoe" , "Light open shoe" .)
