People are being urged to help protect Croxley Common Moor by the group who protect and promote it as a nature reserve.
The beauty spot has lots of open space, rich and varied wildlife and the benefit of a river running alongside it.
It is also the only nature reserve in the Three Rivers District Council area to be a Site of Special Scientific Interest because of its rich variety of wild flowers.
Graham Everett is the secretary of Friends of Croxley Common Moor. He said the Moor has been a godsend during lockdown for both locals and visitors but said the downside has been greater misuse, especially litter, BBQs and fires.
He said: “Littering is of course illegal everywhere. Allowing dog fouling is specifically forbidden on Croxley Common Moor. As landowner, Three Rivers District Council has also banned fires/BBQs, motor cycling, hunting/shooting, metal detecting.
“Fires/BBQs are particularly undesirable, because of the vegetation damage and risk of further damage if a fire spreads.”
Mr Everett urged visitors to the moor who saw people doing any of these banned activities to point out that they are illegal.
He was supported by Three Rivers District Councillor Chris Lloyd who represents Croxley Green.
He said: “I have valued Croxley Common Moor since childhood, we have seen unacceptable behaviour this summer. Please help protect Croxley Common Moor by taking your litter home and by not having barbecues.
“I would like to thank the Friends of Croxley Common and many other people who have been actively picking up litter. I would encourage you to get involved in the work of the Friends of Croxley Common Moor when their working parties restart.”
