Marin Wildlife Watch

Using motion-activated cameras to study mammals on Marin public lands.


New Cloud-based Platform Launches

Marin Wildlife Watch has updated its image cataloging technology. This will keep the wildlife camera images well-organized and protected for future research. This technology will pre-screen images to expedite cataloging. It also allows volunteers to catalog images remotely, from home, a library, or anywhere a computer and Internet connection are available. The first volunteer training sessions took place in winter 2024. Visit One Tam to learn more about Marin Wildlife Watch, including volunteer opportunities.

Wildlife Insights is a cloud-based service for image identification, data management, and analytics. It is a collaboration of major wildlife conservation groups, technology partners, and philanthropy partners.


Name Change

The Marin Wildlife Picture Index has been renamed Marin Wildlife Watch.

First Findings

After three years and over four million images, the Marin Wildlife Picture Index released its first findings to the County Board of Supervisors.  

Project Overview

The Marin Wildlife Picture Index is a collaborative project to help researchers learn about mammals living in Marin open spaces. A network of motion-sensor cameras placed on public lands collect images, without disrupting wildlife activity.

Cataloged images are entered in to a cloud-based database, allowing researchers to identify species, the number of individuals, and the date, time, and location of wildlife activities. This data will help establish baseline abundance of individual species and mammals in general, identify wildlife hotspots, and determine population trends to indicate the well-being of wildlife in the area. 

Wildlife Picture Index Project (WPI) technology is internationally used and recognized as a method of passively collecting reliable, accurate, and rigorous scientific data on wildlife diversity and abundance. Abundance is a metric that tells you the relative representation of animals within a given area. For this project, the relative area is where the cameras are set up in Redwood Creek Watershed and San Geronimo Valley.

This project relies on community volunteers who meet regularly to catalog images and help service nearly 200 field cameras. Over 5 million images have been gathered over consecutive years, beginning in 2014. View the calendar for upcoming volunteer opportunities.
