This paper by Bob Mizon looks at best practice relating to external lighting – Different types of lighting through the years, terminology guide, threats to the environment from blue-rich white lighting, putting light where it is needed, part-night switch-offs and common misconceptions met when discussing quality lighting and good practice…
Benefits of dark night skies
- People: Our sleep can be disrupted by too much light at night. At worst, it can lead to more serious health issues
- Wildlife: Many birds and animals are affected by stray light at night, affecting their breeding cycles and feeding habits. Controlling stray light helps bats, birds, moths and other nocturnal creatures to go about their business and thrive
- Enjoyment and education: There is increasing interest, wonder and amazement at the incredible array of stars above us. Stargazing is a fabulous educational activity for all
- Money: Substantial savings can be made by Local Authorities, businesses and individuals from turning off or dimming down unnecessary lighting
- Saving energy: There is no point shining light into the sky. Energy wastage can be considerably reduced by ensuring light is directed only where it is needed
- Rural tourism: Other areas designated for their dark skies have seen greater visitor numbers, even in winter, leading to increased business for B&Bs, retailers, and others catering for visitors
- National Landscape: 50% of the National Landscape is above us! Dark night skies are definitely outstanding, natural and beautiful, and should be conserved and enhanced along with the rest of the National Landscape
International Dark Sky Reserve
Cranborne Chase National Landscape became the 14th Reserve across the globe in October 2019, and joins an exclusive club of International Union for the Conservation of Nature (IUCN) Protected Areas to gain international recognition for its dark skies.
“Some people are lucky enough to recognise ‘the Plough’, but for others, seeing stars and their constellations is often impossible because of light pollution. Here in Cranborne Chase we can see the Milky Way and the Andromeda galaxy, if the clouds allow!” Linda Nunn, Director of Cranborne Chase National Landscape
The Reserve designation can only be given by the IDA to those areas that enjoy exceptional starry skies and have pledged to protect and improve them for future generations.
To achieve International Dark-Sky Reserve status, Cranborne Chase National Landscape was put through a series of stringent checks by the IDA.
Linda Nunn, continued: “We have taken meter readings of the darkness of the night sky for several years and we are hugely grateful to the Wessex Astronomical Society for their support. We must also thank Bob Mizon as we could not have achieved this without his help, or the support of the local authorities and parish councils and we look forward to working with them as we continue to improve our dark skies.
“Although huge amounts of work have already been done to achieve this status, we must continually improve our dark skies. Dark sky friendly schemes with schools, business, parishes and landowners are being developed and Wiltshire Council, which administers two-thirds of the area, has already agreed to upgrade its street lighting. This will make a significant contribution and will help us continually improve our dark sky quality. This is a requirement of the International Dark-Sky Association (IDA) to ensure we maintain our exclusive status.”

Work has included auditing external light fittings within the National Landscape, consulting with the local planning authorities, and working with local communities and parishes to achieve non-polluting good lighting and providing training on reducing light pollution for everyone.
