Wild tiger seen in park (9)
I believe the answer is:
serengeti
'park' is the definition.
(Tanzanian national park)
'wild tiger seen' is the wordplay.
'wild' indicates anagramming the letters.
'tiger'+'seen'='tigerseen'
'tigerseen' with letters rearranged gives 'SERENGETI'.
'in' is the link.
(Other definitions for serengeti that I've seen before include "Green ties (anag.)" , "Wildlife-rich region of Africa" , "place to watch game" , "region in Tanzania" , "area of Tanzania" .)
