Oh what a shame! Sorry to hear that. I agree with the suggestions of prickly plants and nettles etc. But also, have a word with your Neighbourhood Policeman, it's what he/she is for. While the children are young there's a chance to influence them by the police giving a talk at their school etc, and walking around talking to parents - whereas if the damage was done by teenage louts things like that don't sway them, in fact it probably makes them worse.
And what about some Anti-climb paint? Contrary to popular opinion it is legal to use it as long as you conform to certain stipulations https://www.askthe.police.uk/content/Q726.htm , and in fact just putting the warning signs up might be enough to keep some people away.
It's sad - when I was a child I lived in the middle of nowhere, and spent my days exploring, taking risks, making camps, damming ditches and doing all sorts of stuff and no one bothered me because the area was wild. Children don't get enough 'wild' nowadays
