Join us for City Nature Challenge 2021!

Woodland Park Zoo and Point Defiance Zoo & Aquarium 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 2021 – 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 30 – Monday, May 3, 2021

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!

Find out more on the Seattle-Tacoma Metropolitan City Nature Challenge 2021 iNaturalist project page.

The 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 30 – May 3, 2021
Take and upload pictures of wild plants and animals.


April 30 – May 9, 2021
Help identify what was found.

Please keep an eye on your local and federal health recommendations to help you decide how you want to participate. 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 2021 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 2021 City Nature Challenge: Seattle-Tacoma Metropolitan Area iNaturalist project
    3. Identify observations to species level. Try searching iNaturalist for observations without identifications or for observations that still need to get down to species
