About the event

Join the bat roost counts on Saturday and contribute to new urban biodiversity research with the Natural History Museum of L.A. County and HFAC educators! 

Your participation will help scientists understand urban bat populations, locations, how they react to human disturbances like noise and light pollution, and prepare conservationists to respond to the spreading threat of white nose syndrome in case it reaches Southern California. You’ll be part of a team of community scientists doing field research, counting bats as they depart from a freeway bridge spanning the San Gabriel River. This information will help understand a little-studied part of bat research: bats in the city.  Join the Bat Roost Counts and get a close-up look at nature in L.A.!
