Said to be placed amid wild deer (7)
I believe the answer is:
reputed
'said' is the definition.
(thesaurus)
'placed amid wild deer' is the wordplay.
'placed' becomes 'put' (I've seen this in other clues).
'amid' indicates putting letters inside.
'wild' indicates anagramming the letters.
'deer' anagrammed gives 'reed'.
'put' placed within 'reed' is 'REPUTED'.
'to be' acts as a link.
(Other definitions for reputed that I've seen before include "Generally believed (to be the case)" , "Regarded as such" , "Generally believed to exist" , "Considered" , "Erupted (anag)" .)
