City Nature Challenge 2018
From April 27 - 30, over 60 cities around the world are competing to see who can document the most diversity in the natural world using the iNaturalist app.
Join us at Lake Lagunitas on Saturday, April 28 from 10 a.m. - 2 p.m. for guided excursions, iNaturalist "how-to's" and independent identification sessions.
You must download the iNaturalist app, create an account, and join the San Francisco Bay Area project to participate in the challenge. For instructions on how to make observations using your iNaturalist app on your iPhone or Android phone, visit the iNaturalist website.
Documenting Changes in the Life of the Mountain
Over the past century of MMWD's stewardship, great changes have taken place in the types of plants that grow on Mt. Tamalpais and where those plants grow. We have seen species come and go and shift their locations or flowering times. In the coming century we will see even more changes.
To mark the district's centennial in 2012, we started a series of projects to create a snapshot cataloging current plant life on the watershed. We will use this snapshot to compare against past records as well as a baseline against which future change will be measured.
The multi-year effort has brought together botanical experts from around the Bay Area and more than 100 volunteer Citizen Scientists. During four bioblitz survey days, participants recorded more than 1,400 observations comprising over 500 kinds of plants, over half of the estimated 900 plant species living on the watershed. We are optimistic that 2014 will provide us with another great year of bioblitzes, but we need your help!
Stewardship has expanded beyond the weed wrench!
MMWD and the California Academy of Sciences have engaged with the public to document the plant biodiversity of Mt. Tamalpais.
We have observed or collected about two-thirds of the 935 species of plants on the watershed. Can you help us collect the rest?
Through this project, participants deepen their relationship with the mountain, develop a better understanding of how science works, and help us build a baseline inventory that informs conservation measures.
The bioblitz model is an intense search in a predetermined, discrete plot. In order to find the remaining plants, we will need to map more locations and "safari" participants will need to visit more than one location per foray. We hope you can help! We will post more information about this exciting volunteer opportunity soon. Please check back!
Rare Plant Treasure Hunts
The Rare Plant Treasure Hunt (RPTH) is a volunteer program started by the California Native Plant Society (CNPS) that was designed to get people excited about rare plant conservation as well as to gather important data on rare plants around the state. Almost half of the rare plant populations in California have not been documented in more than 20 years, and recent data is needed to ensure their long term conservation. Volunteer botanists, both amateurs and experts, search for and document historical and new rare plant populations.
MMWD and CNPS are continuing their partnership with Rare Plant Treasure Hunts on Mt. Tamalpais. Come explore parts of the mountain that you've never seen before, learn about Mt. Tamalpais' unique rare plants and improve your botanical skills. Each trip starts mid morning and lasts four to six hours. Dates and trip descriptions are available on the Rare Plant Treasure Hunt event calendar, and more information can be obtained through email.
