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!

Data collection and monitoring

NatureMapping is your chance to become a citizen scientist: to observe, monitor and inventory your local habitats and use that information to make real change. The data you collect can be used by scientists on state and local levels to help make decisions that create a healthy future for fish and wildlife.

NatureMapping Field Trips are free, with no experience needed. Do come dressed for the weather, and for walking in a wet environment on uneven surfaces. All field trips are 9 am to noon.

Dates coming soon!

Amphibian Egg Mass Survey
Find frog eggs

Get out and enjoy the natural world while contributing to a real conservation project! You’ll be trained with Washington Department of Fish and Wildlife protocols and learn to identify the egg masses of 8 different species of amphibians. Trained volunteers will receive access to monitoring tools, including waders, digital cameras, and GPS units to monitor for the presence of egg masses monthly from February to August.

Stay tuned for 2019 dates.

ID frog and toad calls

Quick – what frog is this? And what does it sound like? Join FrogWatch and find out.
FrogWatch USA is a national citizen science program of the Association of Zoos and Aquariums (AZA) that teaches volunteers to identify local frog and toad species by their calls during the breeding season, and how to report their findings accurately. Volunteers collect data during evenings from February through August. This data is analyzed to help develop practical strategies for frog and toad conservation.

Stay tuned for 2019 dates.
