Six thousand trees have been cut down at a beauty spot on the outskirts of Darwen, Lancashire, after a health and safety survey.
A 12-hectare site beside the A666 near the Green Arms Road junction has been cleared in the last month by United Utilities.
And police and councillors said the felling programme would have the benefit of discouraging strangers from meeting up for sex at the known 'dogging' hotspot.
Sergeant Mark Wilson of Darwen Neighbourhood Policing team, said the tree felling would help reduce incidents of 'dogging'.
He said: “It’s an on-going problem and very worrying for members of the public.
“It’s far too early to tell if cutting the trees back has had any impact on the dogging situation, but we’ll be paying regular attention to the area.”
