Ring Mountain City Nature Challenge Bioblitz

  • Ring Mountain Preserve Taylor Road Tiburon, CA, 94920 United States (map)

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 third annual City Nature Challenge, an international community science competition to see which urban area can document the most nature.
