It is BioBlitz time! Cabrillo National Monument is joining The City Nature Challenge by hosting a BioBlitz at the park!
Description: On Saturday, April 26th, Cabrillo National Monument is hosting a BioBlitz! Spend the day, during regular park hours, documenting incredible biodiversity using the iNaturalist app. iNaturalist is a platform where people share audios or photos of living organisms through submissions called observations. A BioBlitz is a fun, community-driven event focused on recording as many species as possible – including plants, animals, and fungi. This event is part of the City Nature Challenge, a global effort to promote biodiversity awareness and citizen science. It’s a friendly competition and a great way to connect with nature!
We’ll kick off the day with two educational walks at 9:30 AM and 11:30 AM. Afterwards, continue exploring and logging your discoveries on iNaturalist to help support conservation efforts.
Let’s come together, connect with nature, and make a difference! Hope to see you there!
Please register in advance to join us!
Join our iNaturalist project before you arrive, then snap, tag, and BioBlitz like a pro!
