RSVP is required.

Join Marin County Parks and One Tam at Gary Giacomini Preserve as we try to identify and document every living species we see! Hone your naturalist skills, learn to use the iNaturalist smartphone app, and contribute valuable data about the region’s biodiversity. San Geronimo Ridge has some beautiful serpentine habitats, and you will get an opportunity to learn from local experts about the unique plants and their pollinators!

We will be taking observations in the field from 9 AM to 12:30 PM, and then return to the San Geronimo Valley Community Center to have lunch, upload observations, discuss identifications, and win prizes at a free raffle! This optional afternoon session goes until 3 PM.
