Connect with Nature on iNaturalist!

Monday, April 6 - Sunday, May 31

One of the world’s most popular nature apps, iNaturalist helps you identify the plants and animals around you. Get connected with a community of over 750,000 scientists and naturalists who can help you learn more about nature! What’s more, by recording and sharing your observations, you’ll create research quality data for scientists working to better understand and protect nature. iNaturalist is a joint initiative by the California Academy of Sciences and the National Geographic Society.

That’s the vision behind iNaturalist. So if you like recording your findings from the outdoors, or if you just like learning about life, join us!

You can even contribute while sheltering in place by exploring your neighborhood, your backyard or front yard, or even the wildlife inside your home.  Plus, you can always explore the 33 million+ observations from all over the world!
