Ijams BioBlitz 2024 and the City Nature Challenge

What is a BioBlitz?

A BioBlitz is an event that focuses on finding and identifying as many species as possible in a specific area over a short period of time.

What is the City Nature Challenge?

Ijams Nature Center is proud to partner with Zoo Knoxville, Discover Life in America, Sierra Club, and the City of Knoxville to coordinate a BioBlitz for the City Nature Challenge 2024. During the City Nature Challenge, cities all over the world will collaborate to observe as much wildlife as possible. Help us record observations of wild plants, animals, fungi, and more to see how much nature we can find across the planet while learning who lives nearby!
