Countryside campaigners gathered at Sheffield Town Hall to call for the campaigning spirit of the Kinder trespassers to be revived to protect national green spaces.
Kate Ashbrook, general secretary of the Open Spaces Society, spoke at the Spirit of Kinder event marking the 82nd anniversary of the famous Peak District mass trespass.
She said: “The governments in England and Wales are attacking our green spaces, making it almost impossible for local people to register them as town or village greens to secure their rights to enjoy them.
“The cuts in local authority funding and the obsession with development mean that budgets for maintaining, creating and recording public paths have been slashed.
“It’s time that the Government recognised that open country, green spaces and public paths are not a luxury but a vital need.”
