When: Friday, January 5th, 2024, 1–3 pm;
Where: Mount Tam - exact meeting location will be sent in the confirmation email upon registration. Registration is required.
Join One Tam for a nature and science adventure! A bioblitz is a quick, intense survey of the species present. Hone your observation skills, learn about forests, and look for mushrooms & more! We will collect mushrooms (with our scientific collection permit) and take them to the Mill Valley Rec Center to be displayed at MycoMarin Fungus Fair on 1/6. Nature-curious folks of all ages and experience are welcome.
We will meet on Mt. Tam at the Bootjack parking lot and hike 1-3 miles on varied terrain at naturalist pace. Heavy rain and wind cancels the event.
Participants 15 & younger must be accompanied by an adult. Participants 16-17 must have an adult guardian signature ahead of time or at drop-off.
