Nervous, caught in forest I venture (7)

I believe the answer is:

restive

'nervous' is the definition.
('restive' can be a synonym of 'nervous')

'caught in forest i venture' is the wordplay.
'caught in' indicates a hidden word.
'RESTIVE' can be found hidden inside 'forest i venture'.

(Other definitions for restive that I've seen before include "Resisting control, nervous or impatient" , "Uneasy, nervous" , "Unable to keep still" , "Impatient - jumpy" , "It veers around, resisting control" .)

I've seen this clue in The Telegraph.
