Oregon Spotted Frog

Amphibian Monitoring Program

Citizen scientists have joined the zoo and Washington Department of Fish & Wildlife to document native frog populations living in our local parks. The more we learn, the better we can protect the vanishing wetlands of Washington.

Get involved!

Otter Spotter Community Science Initiative

Sentinels of Ecological Health

River otters are found in water systems all over Washington state and we need your help to spot them! If you observe a river otter, please report your sightings to help us capture data on otter range and behavior.

City Nature Challenge

April 27 - 30, 2018


Join Us in a Fun Nature Observation Competition!

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


Download the App


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

To 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 2018 City Nature Challenge: Seattle Metropolitan Area iNaturalist project
  3. Take photos of wild plants, animals and fungi in the Seattle metro area
    • Only species in the wild count for this competition! Cultivated plants in a garden or non-native animals at the zoo won’t be counted as observations for City Nature Challenge.
  4. Upload your photos to iNaturalist – from your mobile device or via your computer
  5. Learn more as the iNaturalist community helps identify your observations

To help identify observations:

  1. Download the free iNaturalist app to your Android or iPhone
  2. Join the 2018 City Nature Challenge: Seattle 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


Check your local library branch, nature center, park, zoo or aquarium to learn of events you can join during the City Nature Challenge weekend to log observations with others! Here are a few options to get you started:
