Extremely crafty journalists found in tree (7)
I believe the answer is:
cypress
'tree' is the definition.
(cypress is a kind of tree)
'extremely crafty journalists' is the wordplay.
'extremely' means to remove the middle letters (only the extremes of the word are used).
'journalists' becomes 'press' (the press can mean the newspaper industry).
'crafty' with its middle removed is 'cy'.
'cy'+'press'='CYPRESS'
'found in' is the link.
(Other definitions for cypress that I've seen before include "Evergreen, mourning symbol" , "Dark-leaved conifer" , "Tree with funereal associations" , "One living in churchyard" , "Evergreen tree" .)
