Warning from drivers: stop growth of planes etc (11)

I believe the answer is:

forestation

'growth of planes etc' is the definition.
(plane is a type of tree)

'warning from drivers stop' is the wordplay.
'warning from drivers' becomes 'fore' (warning given by golfers 'driving' on a course).
'stop' becomes 'station' (I've seen this before).
'fore'+'station'='FORESTATION'

I've seen this clue in The Times.
