Grit City Carnivore Project
Report coyotes and raccoons.

Northwest Trek is partnering with the Schell Lab at the University of Washington, Tacoma and Point Defiance Zoo & Aquarium on a community science project – reporting sightings of carnivores like coyotes and raccoons in the greater Tacoma area.

We’re setting up cameras from Tacoma to Eatonville to record wildlife, and we need to you report what you see on the iNaturalist app so everyone can learn more about our local wildlife. Join us!
