Wales will this month will become the first UK nation to introduce national good practice guidance to help protect its dark skies.

‘Good Practice Guidance: Planning for the Conservation and Enhancement of Dark Skies’ will help ensure people’s well-being, while helping both stargazers and wildlife thrive in Wales for generations to come.

Endorsed by the CEO and Executive Director of DarkSky International, it is aimed to assist all involved in planning decisions – such as developers and local authorities – to focus on the right light at the right time in the right place to ensure continued spectacular star-gazing opportunities.

Avoiding light pollution – which wastes money, energy and carbon – also benefits Wales’ cultural heritage and its tourism offer, with the country already renowned for having the highest percentage of protected dark skies in the world.

Wales boasts internationally recognised Dark Sky Reserves where visitors can see up to 2,000 stars at a time, compared to less than 100 in most urban areas, where actions arising from the guidance can make a difference.

Parts of Wales have also earned prestigious designations as a Dark Sky Park, Dark Sky Sanctuary and Dark Sky Community.

CEO and Executive Director of DarkSky International, Ruskin Hartley, said: “DarkSky International congratulates Wales on its leadership in dark sky conservation, celebrating a Decade of Darkness with Eryri National Park’s 10th anniversary as an International Dark Sky Reserve.”

The guidance, produced through close partnership between Welsh Government, local authorities, Wales’ Designated Landscapes and Natural Resources Wales, launches in time with Dark Skies Week, from February 21, when people across the nation will turn their eyes to the winter constellations.

Cabinet Secretary for Economy, Energy and Planning, Rebecca Evans, said: “The night sky is one of our most precious natural treasures, and I want to ensure it’s preserved for future generations to discover and cherish.”
