BTO research harnesses citizen science to make breakthroughs in bat monitoring

New BTO research shows how data collected by an army of volunteer citizen scientists have been used to map bats in unprecedented detail. The Norfolk Bat Survey began in 2013, and represents a novel way of collecting high-quality and extensive data sets on the distribution and activity of bat species.
