Consultation on future of Surrey's commons
People who enjoy some of Surrey's most popular beauty spots are invited to have their say on their future management.
Many of the county's heathlands boast a diverse wildlife and are designated Sites of Special Scientific Interest.
But the Surrey Wildlife Trust (SWT) said several areas face a threat from invading scrub, trees and grasses.
The consultation affects Thursley, Ockley, Elstead, Royal and Bagmoor Commons, near Farnham.
An SWT spokesman said: "It is not an option to do nothing and let the Commons decline as an internationally-important wildlife site."
The consultation is being carried out by SWT in partnership with Natural England and the Ministry of Defence, which uses part of the Commons for training exercises.
