Event Overview

Calling all nature lovers and community scientists across the commonwealth!

From April 25 - 28, 2025, join Virginians and others around the world for the 2025 City Nature Challenge! Don’t let the word “city” fool you—observations can be made anywhere, including your own backyard.

Explore the opportunities below to learn how you can get involved. Hone your iNaturalist skills or enjoy a guided hike led by TNC staff and volunteer naturalists. Help add to our knowledge of the biodiversity in our urban spaces.

We will be updating this page throughout the month of April with local events in your community. Stay tuned!

Participating in the City Nature Challenge is easy:

From April 25-28, 2025, find wildlife or plants in your community—or even in your own backyard.
Take a picture!
Join a project near you, and share your observations through iNaturalist, an app that allows community members to record what they see in nature and interact with other nature enthusiasts.

*No iNaturalist project nearby? No problem! It's not necessary to contribute to a project to enjoy using the app. Making and identifying observations are by far the most important part of iNaturalist.

Explore Your World

There are many ways to look for nature in your home or backyard.

Discover the plants that are growing on their own and the insects and pollinators that live in and around our homes and yards. You never know what you might find!

HOW TO FIND INSECTS

Insects are probably some of the easiest organisms to find in and around our homes, since they’re abundant and incredibly diverse! But where should you look to find them? What can you use to catch them?

These sites provide some guidance on how to find and temporarily hold insects. Be sure to release them after you've posted your observation on iNaturalist!

MOTH LIGHTING

Setting up a light and a sheet to attract moths is a simple and easy way to bring more nature into your backyard. Photographing moths on the sheet is easy, and you’ll definitely attract other flying insects as well!

Science Friday has a great set of instructions for observing moths, and the Devon Wildlife Trust's video shows how to build your own moth light to attract a wider variety of moths. (Note: In the video, "torch" is British for flashlight.)
