When you report a coyote showing signs of mange, your observation joins a map that no agency or researcher could build alone. For example, iNaturalist has documented over 200 million observations worldwide because people paid attention and contributed what they saw. That's citizen science.

MangeTracker brings people power to Marin County's coyotes.

This is the test: Can a community of neighbors document how widespread mange actually is — and begin to reveal the patterns behind it? Where does it cluster? What time of year? Is there a connection to rodenticides? No single expert can answer that. But hundreds of neighbors and animal lovers paying close attention? That's a different story.

The people who share a landscape with wildlife are its most important observers.

Project Coyote sponsors this project and shares that belief. Their work has helped shift how people across the country see coyotes — from animals to be feared to neighbors worth understanding.

The tool was designed and built by Gina Farr — a Marin wildlife educator, environmental awareness trainer, and coyote behavior expert with nearly two decades of field experience, including 17 years alongside Project Coyote.

Marin will be one of the first communities in the country to track mange in coyotes this way. We're doing it neighbor by neighbor, sighting by sighting — because every animal matters, and every person who cares is a scientist driving change from the ground up.

Let's prove what we can do.
