as the Greens are reliant on local volunteers to keep going, including finding new trustees and fundraising, not all volunteer-run trusts have survived; a number have been changed by Natural England and the Charity Commission; usually the Local Authority ends up being the trustee of the Green. Whilst the object of the creation was for the Greens to last in perpetuity, with most of them given a 999 year lease, nevertheless, they are vulnerable to compulsory purchase if the local authority wants to change the use of the land.
