Mt. Tam

Saturday, May 5, 2018, 9am - 3pm: Slide Ranch Bioblitz - Hosted by National Park Service, One Tam, and the Mill Valley Library

Slide Ranch Bioblitz - Hosted by the National Park Service, One Tam, and the Mill Valley Library

Join the National Park Service and One Tam at scenic Slide Ranch, where Mt. Tam meets the sea, 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 Mt. Tam’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 coastal prairie, coastal scrub, and coastal bluff habitat to look for rare species and weeds alike. We will also see some coastal critters in Slide Ranch’s famous tide pools.

We will be taking observations in the field from 9 AM to noon, and then move to the Mill Valley Library, discuss identifications, and upload our observations. 

Meeting Location: We will be carpooling from the Muir Beach Parking Lot on Pacific Way, as parking at Slide Ranch will be extremely limited that day. Please meet at 8:45 AM to get into carpools. Carpools will return to the parking lot after the morning field portion (noon).

This event is best suited for ages 9 and up; those under age 16 will need a parent or guardian present. 

What to Bring:

- Closed-toed shoes are required. Bring layers in case of weather changes, a hat, and sunscreen. 

- Bring a lunch and water. Extra water and snacks will be provided. 

-A completed Volunteer Agreement Form. We will have them available on site as well. Volunteers under the age of 18 must have the parent/guardian approval section signed.

- It is recommended that you bring a smartphone with the free iNaturalist app downloaded. Pairing up is also an option, and we will have some tablets for teams to use as well.
