New national planning guidance published on Sunday by communities secretary James Brokenshire orders developers to do more to protect wildlife. Ludlow Swift Group will welcome his insistence that developers install swift bricks in new homes. Pricklebums Hedgehog Rescue and the British Hedgehog Preservation Society will welcome the obligation for developers to install hedgehog highways. There is more to this guidance which strengthens requirements for developers and councils to seek a net gain in biodiversity when developments are built. This is a welcome announcement but there is wriggle room in the guidance and a lot will depend on local interpretation. Wildlife groups and communities will need to lobby Shropshire Council to ensure that its forthcoming local plan has the strongest measures possible to protect and enhance biodiversity. Those measures might include a “greening factor”.
