The Bumblebees of

San Francisco

Quinn S. McFrederick

My research investigates the Bombus community in San Francisco. I am looking at bumblebees in parks with the goal of detecting what types of parks are home to the highest diversity of bumblebees. In addition to sampling bumblebees in 17 city parks I am studying the floral community , the availibility of nest sites, the surrounding matrix, and the amount of different habitats in each park. This information will tell us what makes a good park for bumblebees. If you are interested in monitoring bumblebees in your backyard please e-mail me at
