The City Nature Challenge began as a friendly competition between two California museums in 2016 and has grown into an international celebration of biodiversity and community science.

A few years ago, we joined several local partners to host a local CNC for Alachua County and invite our community to explore and document the plants and animals nearby. Despite the pandemic, these last two years have brought many local friends and supporters outdoors because it’s a fun activity that can be safely socially distant.

The 2021 CNC in Alachua County scored well over ten thousand observations! Almost 1,900 species were spotted, from the familiar to the very unusual, including natives and non-natives for our area. You can check out the iNaturalist CNC 2021 page to look at what people were discovering last year and explore the map of where they were spotting these plants and animals.

We hope 2022 brings even more observations than previous years. Please plan on joining us in this fabulous community science project to better understand our natural world in Alachua County. While we can share great nature shots and learn about our local plants and animals, large amounts of biodiversity information can also help scientists learn more than ever before.
