Character to do duty again in wildlife sanctuary (6,7)
I believe the answer is:
nature reserve
'wildlife sanctuary' is the definition.
I don't know anything about this answer so I cannot tell whether this works.
'character to do duty again' is the wordplay.
I cannot quite understand how this works, but
'character' could be 'nature' (I've seen this before) and 'nature' is found within the answer.
'do' could be 'serve' (serving is a kind of doing) and 'serve' is found in the answer.
'again' could be 're' (prefix meaning 'again') and 're' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...
'in' is the link.
Can you help me to learn more?
(Other definitions for nature reserve that I've seen before include "Say, animal sanctuary" , "Area set aside for wildlife" , "Protected area for plants and animals" , "Place set aside for flora and fauna" , "Managed area for protected flora and fauna" .)
