Join Marin County Parks and One Tam at the scenic 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 Marin's biodiversity. No smartphone? No problem! No experience or special equipment are necessary, just bring your enthusiasm for science and nature. We will be exploring grasslands to look for rare species and weeds alike! menos ↑
