An application to build four 125m-high wind turbines in rural Dorset should be refused, according to a planning report.
Energy firm Infinergy wants to build the wind farm on land off Puddletown Road in East Stoke, near Wareham.
Planning consultants for Purbeck District Council have recommended councillors turn down the proposal when they meet on Tuesday 30 November.
The report expresses concern over the environmental effects of the turbines.
The proposed site, formerly Masters Pit, is close to a year-round Scout camp and is flanked by a designated Site of Special Scientific Interest, internationally important wetlands, a Special Area of Conservation and a Special Protection Area.
Planning board chairman Peter Wharf said: "The recommendation has been made after receiving expert advice and undertaking months of research.
"We have received over 700 written responses and all factors have been taken into account when preparing the recommendation."
The board is due to decide on the proposal in a special meeting at Purbeck School, Wareham, on 30 November at 1900 BST.
Seating will be limited to 400.
