The Welsh Government has published the revised Section 7 list of species and habitats under the Environment (Wales) Act 2016, updating the statutory register of species and habitats of principal importance for maintaining and enhancing biodiversity in Wales. The refreshed list, led by Natural Resources Wales in consultation with key stakeholders, represents an expansion to 1,322 species and 69 habitats, including bird species such as Swifts, Starlings, Rooks and House Martins that have experienced significant population decline across Wales. Planning authorities are advised to have regard to the revised Section 7 list, follow a step‑wise approach to deliver net benefits for biodiversity and secure enhancement primarily on site or immediately adjacent to development, including suitable provision for nesting, such as swift bricks, where relevant.
