Join us for City Nature Challenge 2024!

We are thrilled to help mobilize people across the Seattle-Tacoma metropolitan area (all of Snohomish, King and Pierce counties) to join the City Nature Challenge 2024 – a nature observation event using the iNaturalist app. Not familiar with the app? Not to worry, it’s super user-friendly.

City Nature Challenge

Runs from Friday, April 26 – Monday, April 29, 2024

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!


April 26 – April 29, 2024
Take and upload pictures of wild plants and animals.


April 30 – May 5, 2024
Help identify what was found.

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!


Be an Observer

  1. Download the free iNaturalist app to your Android or iPhone (lots of helpful how-to videos on the iNaturalist website)
  2. Join the 2024 City Nature Challenge: Seattle-Tacoma Metropolitan Area iNaturalist project
  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!
  4. Upload your photos to iNaturalist - from your mobile device or via your computer


Help Identify Observations

  1. Download the free iNaturalist app to your Android or iPhone
  2. Join the 2024 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.

How To Participate


The Empathy Collaborative is a three-year project working in partnership with south Seattle communities and Antioch University Seattle to co-design opportunities for youth and families. The purpose of this work is to build long term, authentic relationships by designing programming that is responsive to community interest and priorities and reduce traditional barriers to participation in empathy-based programs.

Through a collaboration with the Empathy Collaborative Project and feedback provided by south Seattle communities, the City Nature Challenge now offers supporting resources in Chinese, Russian, Somali, Spanish, and Vietnamese. This “How To Participate Handout” can be distributed digitally and or printed and displayed on signboards or at community events.
