On September 19th, the Missouri Department of Conservation, St. Louis County Parks and Recreation, Great Rivers Greenway, and community partners invite you to take part in a BioBlitz. Help us we record as many species as possible within 24 hours (from birds and bugs to plants and pollinators) in a single area along the Mississippi Greenway/Cliff Cave Park area.

What is a BioBlitz?

A Bioblitz is when teams of scientists, students, and community members work together to identify and record as many living species (plants, trees, liches, mosses, bugs, bees, lizards etc.) as possible within a specific area over a specific time frame. It’s a fun and engaging way to learn about local biodiversity and contribute to scientific research. This not only helps community members grow their appreciation for nature in their own  “backyard,” but can also help drive conservation and land management decisions, understanding of local diversity, and possibly even discover a new species!

To identify these species, you’ll use an app called iNaturalist. Never used it before? Don’t worry, we made a how to guide you can check out here!

Two Ways to Participate

  1. Participate by collecting data on iNaturalist anytime on your own on September 19 (no registration required!).
