Join Marin County Parks and One Tam at Ring Mountain 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 Bay Area’s biodiversity. Ring Mountain has many unique serpentine species, and you will get an opportunity to learn from local expert, Liam O’Brien, about butterflies, moths, and their host plants.

This event is part of the 3rd annual City Nature Challenge, an international citizen science event to see which city can document the most nature.

No smartphone? No problem! No experience or special equipment are necessary, just bring your enthusiasm for science and nature. We will be taking observations in the field from 9 AM to noon, and then move to a nearby wifi-enabled location to eat lunch, discuss identifications, and upload our observations. 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 GPS cameras for teams to use as well.
