One important outcome of our long-term study of pollinator dynamics in the San Bernardino Valley is to establish a baseline set of data from a semi-natural area where human impact is now minimal.

Along with a number of colleagues, a standardized protocol for pollinator monitoring was developed in hopes that data collected on pollinator populations in the future will be comparable across studies. This protocol can be found at (
