Holes, Ramps, Debris

Home covert woods near entrance from lower end of Fen Meadow along house line in woods, looks like kids have dug massive holes, used ramps or made ramps from dirt dug and trodden path, cut down trees and left in the way and using woodland for debs etc. Whilst it’s great kids are making there own activities, the holes and ramps are dangerous for walkers and especially dogs they won’t see it - this is not the first time this has happened in this area. Urgent attention required. Thanks.
