There Will (Now) be Butterflies Over the White cliffs of Dover

We apparently have to thank the late Dame Vera Lynn for heading a drive for the National Trust to take over fields atop the white cliffs of Dover (https://www.theguardian.com/environment/2020/jul/04/dover-clifftops-buzzing-with-wildlife-after-national-trust-takeover). The fields (formerly marginal agricultural land) have been converted into meadows with a wide array of limestone appreciating flowers. This, in turn, has attracted masses of insects including butterflies. I can't help but feel that the country needs to do much more of this with land formerly used to grow and graze. It's all really a question of ownership.
