City Nature Challenge: Greater Portland-Vancouver Metro Area 

April 30 @ 8:00 am - May 10 @ 5:00 pm

Join us to connect with and celebrate nature in our region’s first ever City Nature Challenge–an effort to find and document plants and wildlife in cities across the globe. 

See last years video below to get a taste for what 2021 will be like.

The 2021 City Nature Challenge takes place in 2 parts. You’re welcome to participate in either activity, or both! See the video below for more info based in Portland!

Part 1.

April 30-May 3

Taking pictures of wild plants, fungus, and animals by anyone from the complete novice to the expert

Part 2.

May 4-May 9

Identification of what was found by specialists

Results will be announced on Monday May 10th.

You don’t need to be a scientist or an expert to enjoy this event! Nature is for everyone. For the City Nature Challenge, you just need to follow these three simple steps:

(1) search your favorite outdoor places for plants, animals, or any other evidence of life in your city

(2) snap some photos

(3) share your observations on iNaturalist—a web-based social network for sharing biodiversity information across the globe! Shortly afterwards, a local or online expert will review your observation and help identify the species, and you’ll contribute to an amazing worldwide effort that generates scientifically valuable data.

You can participate in the City Nature Challenge at your own pace, in a group of friends or family, in a virtual classroom or solo! Anywhere from your backyard, to a local park or natural area, as long as it is in the greater Portland and Vancouver area


1- Download the free app from the AppStore or Google Play

2- Open it and sign in

3- Start taking and uploading your photos of living things!
