Night patrols have been stepped up around woodland in Sprotbrough following reports of trees being chopped down and cut into pieces for firewood.
More than a dozen trees, some of which were 40ft high, have been felled illegally using chain saws and hand saws from the corner of Nursery Lane and Cadeby Road.
They are protected by a Tree Preservation Order, which puts people at risk of prosecution if they fell trees without permission.
A local resident said: “It’s been going on for around two weeks. They’re destroying woodland habitat and it would take 50 or 60 years for them to grow back or even longer. They have got no respect for what they’re damaging and I’m very frustrated.”
Environment spokesman Coun Christine Mills said: “We are working with the landowner to tackle this issue. In the meantime the council’s area team have added this spot to their night time patrol.”
