Natural England has opened its National Trails consultation, which will look at the best way of managing England's extensive trails network in the future.
The consultation will seek to engage local groups and look at alternative, flexible funding structures to ensure the trails are well maintained. It will close on July 5th, so stakeholders have just eight weeks to put forward their suggestions.
Liz Newton, director for access said: "Our National Trails are world-class tourist attractions offering locals and visitors the opportunity to explore England's rich landscapes and diverse wildlife."
She added that careful consideration of how trails are maintained and improved will be needed if the network is to maintain its gold standard for public access.
National Trails are marked with an acorn symbol, which will be familiar to any outdoors enthusiasts who regularly don their walking boots
In total there are 13 routes and they cover a distance of some 3,500 km. They are currently maintained by 50 local highway authorities, but much of the responsibility could be ceded to local groups and organisations.
