Pollinators are crucial to the environment and human survival due to the ecosystem services they provide. Over 80% of flowering plants require animals for their pollination, most by flying insects, whose populations are rapidly decreasing. Protocols to monitor changes in pollinator populations need to be established so we can better understand why these changes are occurring and how best to mitigate further losses. The San Diego Natural History Museum’s role in this project is to set up bee bowls deployed 6 times over 3 months at 27 sites across San Diego County. Preliminary data of pollinator diversity and composition across these sites from a coastal to inland gradient is presented. This work is part of a larger collaborative project aiming to establish a pollinator monitoring plan for San Diego County by combining and evaluating bumble bee and butterfly visual surveys (Pollard Walks), netting transects, bee bowl trapping, volunteer photographic surveys, and vegetation mapping data.
