A landowner has attacked off-road motorists for causing huge environmental damage to ancient green lanes on her farm.
Georgina Britten-Long, of Witchenford, Worcestershire, said those who use off-road vehicles along green lanes were "incredibly dangerous" and had not only churned up pathways but had cut down trees to improve access.
Mrs Britten-Long, chair of the Worcestershire branch of the Country Land and Business Association (CLA), is calling on the Government to ban motorbikes and 4x4s from using green lanes.
Motor vehicles are allowed to use the tracks, if historical evidence suggests they were once a horse and cart track.
But 14 organisations, including the CLA, want to see motor vehicles banned from using the routes, claiming they are causing damage to the countryside.
The Green Lanes Protection Group has welcomed a review on the use of green lanes as part of the National Environmental and Rural Communities Bill.
The Bill seeks to clarify the basis on which motorised vehicles can have the right to drive on the routes. It is due to be reviewed by an independent committee before returning to the Commons.
However, some fear offroading groups are rushing to claim the routes as byways open to all traffic before the new legislation comes into force. This could mean that virtually every green lane will be exempt from the new protective measures.
The Ramblers Association has collated an 'at risk' register of green lanes and suggests that damage has grown significantly over the last years with the growth in ownership of off-road vehicles.
Local authorities only have limited powers to prevent motor traffic from using green lanes on the grounds of environmental impact.
The new Bill goes some way in preventing the right to drive on these ancient tracks, where it is clearly inappropriate for motorised vehicles to do so.
The groups claim motorised recreational vehicles frequently erode the paths that run through farm land and that are enjoyed by ramblers and horseriders alike.
The ruts caused by such vehicles also hinder the routes
used by farmers and land owners, they said.
Mrs Britten-Long claimed some off-road motorists had even used tools to clear pathways through her land.
"They are coming out here with saws and chopping trees down and making an appalling mess," she said.
Many green lanes were originally cattle droving lanes that weren't intended for offroading, she added.
Off-road motorists dismissed the concerns, saying green lanes were legitimate roads for them to use.
However, the Trail Riders Fellowship has advised members on how to use the ancient routes, urging them to respect fellow users.
Richard Olliffe, of British Motorcycle Federation (BMF), said: "Rights of Way are often ancient roads that are legitimately enjoyed by motorcyclists and motorists alike. The Bill appears to contain provisions that will allow a period of grace to allow Byways Open To All Traffic (BOAT) claims already registered to be processed, but let's face it, this is simply a cynical attempt to restrict access by legitimate users."
Jeff Stone, of the BMF, said farmers had, in some cases, blocked pathways in an attempt to stop off-roaders from using the routes.
He said tools had been used to clear pathways, but only where foliage was blocking the public rights of way.
David Price, assistant regional director of the CLA, said he was concerned about the use of vehicles along green lanes.
He said: "There had been a significant increase in the use of motor vehicles along green lanes and it is a cause for concern."
Jacquetta Fewster, director of campaigns at the Ramblers' Association added: "What is needed from this government is tough action now on this destruction of our natural environment."
