City Nature Challenge 2026: Long Island
April 24 – April 27
Join the 2026 City Nature Challenge!
We are excited to announce that LIISMA is partnering with the iNaturalist ambassador program to support the first-ever City Nature Challenge (CNC) on Long Island!
What is it?
The City Nature Challenge is a global community science “bioblitz” organized by the California Academy of Sciences and the Natural History Museum of Los Angeles County. The goal is to document as many wild organisms as possible to create a massive open-access database of local biodiversity.
Event Details
Dates: April 24th – April 27th, 2026
Location: Anywhere on Long Island! (Your backyard, local parks, or nature preserves)
How to Participate: Simply take photos of wild plants, animals, and fungi and upload them to the iNaturalistapp.
Why Participate?
By joining in, you help scientists and conservationists (like us at LIISMA!) better understand our local ecosystems. Your observations help us track native species and identify the spread of harmful invasive species across the island.
