Coast Light: Actionable Science to Manage Coastal Nightscapes

Project Description
The project made the following key findings. 1. Ground-level measures of light pollution correlate with satellite data at the broad-scale, but fine-scale variation in light pollution is large. 2. The World Atlas of Artificial Night Sky Brightness is a better predictor of ground-level light exposure than other satellite-derived measurements such as upward radiance. 3. Beach-level light exposure is the first or second most important habitat factor in our models of habitat use by Western Snowy Plover and California Grunion. Western Snowy Plovers use the darkest beaches, while California Grunion use beaches with slightly brighter conditions but use declines at higher lighting levels.
