BNG - Great Crested Newts The developers use of District Level Licensing for great crested newts acknowledges unavoidable harm to GCN habitat on site.

This undermines the overall ecological integrity of the site and reinforces that the development’s harm to biodiversity cannot be fully mitigated 24
