Black bear photo captured by one of Pepperwood’s motion-activated cameras

In 2012, Pepperwood established North America’s first Wildlife Picture Index (WPI) grid of motion-activated cameras. Citizen scientists help maintain 20+ cameras located around the preserve, and also play a major role in cataloging photos into a database that helps us understand our local animal populations and how they are shifting over time.

Pepperwood manages an additional grid at Audubon Canyon Ranch’s Modini Mayacamas Preserves about 8 miles north of our own preserve. We recently completed management of a WPI project on Sonoma Mountain for the Sonoma County Agricultural Preservation and Open Space District. Pepperwood also advises on additional grids in the North Bay.
