Where God arranged protection for wildlife (8)
I believe the answer is:
hedgerow
'protection for wildlife' is the definition.
'where god arranged' is the wordplay.
'arranged' indicates an anagram.
'where'+'god'='wheregod'
'wheregod' anagrammed gives 'HEDGEROW'.
(Other definitions for hedgerow that I've seen before include "Greenery between fields" , "Field boundary" , "Living boundary between fields" , "Bushy boundary" , "rural boundary" .)
