Heal the Bay BioBlitz: 2025 LA City Nature Challenge

Join Heal the Bay’s Safe, Clean Water Program (SCWP) for the 2025 LA City Nature Challenge BioBlitz, a global event that started as a friendly competition between Los Angeles and San Francisco and has since grown into a worldwide movement!

A BioBlitz is a fun, hands-on community science event where we’ll work together to document local wildlife. By snapping photos of wild plants and animals, you’ll contribute valuable data to a global biodiversity database to help scientists better understand our urban environment. No experience needed! Just bring your curiosity and a smartphone.

We’re offering two BioBlitz locations this year, and both are happening simultaneously, so please choose only one.

When: Sunday, April 27, 10 AM – 12 PM
Where: Gardena Willows Wetland Preserve (1202 W 170th Street; Gardena, CA 90247) OR Ballona Discovery Park (13110 Bluff Creek Dr; Los Angeles, CA 90094)
Cost: FREE
