The Woodland Trust says it is facing a bill of more than £2,000 because of campers leaving litter and broken glass at a beauty spot.
Lake Wood, near Uckfield, has ancient woodland, rock outcrops and a lake providing vital homes for local wildlife.
However, the Trust says an increase in summer parties and camping at the site has meant litter and vandalism have been on the rise – with many visitors throwing rubbish over the 20ft cliff and into the lake below.
A boat has been hired previously to fish the debris from its depths.
In addition, the lake overflow pipe has suffered extensive damage, meaning water levels have dropped – a spokesperson said the resulting emergency work will potentially add yet another £1,000 onto this summer’s bill. They added that damaged safety fencing also needs to be completely replaced, totalling a further £1,500.
Campfires have caused particular alarm as they not only scorch the soil, but could catch and spread in drier weather.
David Bonsall, site manager for the Woodland Trust said: “Lake Wood is a stunning location, and is a precious habitat that we at the Trust have worked hard to safeguard and restore.
“We don’t want to see it ruined by mindless individuals. I’d urge anyone who sees damage being done to contact ourselves and local police. Any help people can offer by litter picking during their walks is very much appreciated.”
Camping, fishing and barbecues are not allowed at Lake Wood. The local police can be contacted on 101, and reports regarding the site can be sent to firstname.lastname@example.org.
Lake Wood is a 19 acre site, filled with a variety of tree, shrub and wildflower species, and features an old carriage drive and cave-like boathouse.
It is home to dormice and almost 60 species of bird, including kingfisher and heron.
