June 2018 - The US Geological Survey Western Ecological Research Center, Point Reyes National Seashore, and One Tam partners are embarking on their second year of bat surveys in Marin County. The collaborative effort aims to shed light on local bat species diversity, distribution, roosting sites, and disease.
Acoustic monitoring to help measure bat diversity is already underway and will cover 31 different sites. Starting at the end of July, bats caught on state and national park lands will be fitted with radio telemetry tags and then tracked to their roosting sites. The number of bats that then emerge from the roost in the evening will be counted, and surveys of the vegetation and other features will help reveal what kinds of roosting habitats the bats prefer.
