News and Events
from One Tam



Dear Friend,

Like most other parts of this year, this holiday season looks a bit different – or maybe a lot different! We hope you stay in good health and find comfort, peace, and ways to safely celebrate with those near and far.

While this year has been incredibly challenging, we are proud of the ways we have adapted and remained resilient at One Tam. Our commitment to the stewardship and care of Mt. Tamalpais has deepened, as we have been reminded time and again of the importance of these public lands to our individual and collective well-being.

Read on to learn about our end-of-year matching gift campaign to raise $15,500 and updates from Bothin Marsh, the Roving Ranger, and how you can contribute to monitoring Mt. Tam’s monarch butterflies if you’re out for a hike during the holiday.

We wish you a safe and happy holiday season.

We’ve got exciting news! Thanks to the generosity of several of our One Tam Ambassadors, your gift to One Tam will be matched dollar-for-dollar up to $15,500. That means your membership gift will double in size and impact! Make a donation here. Thank you in advance!

Got an outdoor and Mt. Tam enthusiast in your life? Consider gifting an annual One Tam membership as a holiday or New Year’s gift. Read about our membership levels here and email Cailey Gibson at for more information.


Bothin Marsh Update

Over 750 people have commented on the conceptual designs for the Evolving Shorelines Project at Bothin Marsh. Thus far, we’ve heard that restoring the tidal marsh and improving the safety of the Bay Trail are the highest priorities for the One Tam community. If you aren’t familiar with the project or haven't yet given feedback on concept designs, please explore our new storymap and provide your input on the survey.


Out and About with the Roving Ranger

If you’ve been out at Lake Lagunitas or Bothin Marsh recently, you may have seen our One Tam Roving Ranger van. With new COVID safety protocols in place, our staff has been able to safely share One Tam updates with community members.

With a new shelter-in-place order now in effect, we’re currently on hiatus, but keep an eye out for the Roving Ranger when you’re at trailheads in the coming months. If you are interested in volunteering with the One Tam Roving Ranger, please email Monica Stafford at


Western Monarchs Need Your Help This Winter!

Can you imagine a winter without the wonderful western monarch? Western monarch butterflies, which visit Marin to overwinter on their incredible continental journey this time each year, have plummeted to less than 1% of their historic population. Their plight is well-known and recently acknowledged by US Fish & Wildlife Service. One Tam partners will be restoring habitat at several sites in Marin to support them.

You too can join local efforts to help them, like planting monarch-friendly plants in your home garden this winter, and participating in our "Time of Thanks” virtual community science project to document them. If you’re headed out for a holiday hike, make it extra special by snapping a picture of any monarchs you might see and uploading it to the iNaturalist project. Don’t stress about getting a perfect shot—blurry photos work perfectly well (and likely mean you didn’t get too close!) Not sure what a monarch looks like? See this page for a description. You can learn more about this special species and their condition here, or visit


iNaturalist Observation of the Month

This observation of western monarch butterfly caterpillars was contributed to our Time of Thanks virtual community science project to help document western monarch butterflies. As mentioned above, these beautiful butterflies are stopping by Marin this winter and community members have been recording their observations via iNaturalist. Although we are primarily interested in monarchs, you can also contribute observations of all butterflies and moths currently on the wing. So far, 62 observers have contributed over 130 observations of 46 species! Help us grow this project by contributing here:
