Car parks at Ashdown Forest are continuing to be vandalised according to conservators.
Volunteers said signs had been removed from 18 carparks and others had been defaced.
The vandalism is “eroding” funds aimed at maintaining the forest..
Ashdown Forest is famous as being the inspiration for the setting of AA Milne’s Winnie the Pooh books.
It is an Area of Outstanding Beauty covering 10 square miles.
The car park signs were previously targeted with graffiti not long after they were installed, following the introduction of parking charges.
