City Nature Challenge

Runs from Friday, April 25 – Monday, April 28, 2025

Help the Seattle-Tacoma Metropolitan Area (including Everett, Seattle, Bellevue, Tacoma and any place within Snohomish, King and Pierce counties!) show the world how biodiverse our region is by making observations of local species during City Nature Challenge!

City Nature Challenge will take place in two parts

You can support this effort by being an observer, helping others identify their observations, or better yet - both!

We encourage everyone to find and document what lives in our own homes, out our windows, on our windowsills and in our backyards, if not in our broader neighborhoods and cities. This can be done by yourself or with your family. You can also participate "online only" by looking through and helping to identify other people's observations!

3. Take photos of wild plants, animals and fungi in the Seattle Metro Area
• This can be inside your house, in your backyard, out your window or in your neighborhood. Please no photos of pets or cultivated plants, but see what "wild" species you can find nearby!

Help Identify Observations

1. Download the free iNaturalist app to your Android or iPhone
2. Join the 2025 City Nature Challenge: Seattle-Tacoma Metropolitan Area iNaturalist project
3. Identify observations to species level. Add identifications to observations from this year’s City Nature Challenge, especially those that still need to get down to species. If you’re new to identifying or want to learn some ways to speed up the process, watch this short video on How to use iNaturalists’s Identify Page.
