Gary Amos attended the inaugural ‘Starlit Skies’ Alliance in Bath on behalf of WHRF. This was attended by many groups interested, (for a number of reasons), in reducing nightime light pollution. A naturalist advised that owls, (of which there are three species in Wookey Hole), affected by light pollution, are unable to hunt as they lose their night vision. Gary, like many astronomers would like streetlights and domestic security lights switched off for at least part of the night to make watching the night sky easier. If light pollution of any type is causing you a problem Gary suggests an informal approach first: many people simply do not realise the implication of bright lights at night, but if that fails you can approach Mendip District Council for help and advice. In the meantime, keep lighting to a minimum to help owls!
