Dear Friend,

We hope our monthly newsletter finds you and your loved ones safe and healthy. We know it continues to be a difficult time for all. We hope you are taking a pause to observe the arrival of spring in your neighborhood and to feel grounded by views of Mt. Tamalpais in these uncertain times.

One Tam's land managers appreciate the community rallying to protect public safety by observing new park restrictions. We are particularly grateful to our One Tam members who continue to support us as we await the full reopening of our parklands. We couldn’t do our work without you, so thank you for being part of our community and supporting the mountain! Not a member yet? Join us.

Over the coming weeks, One Tam's five partner agencies will continue to offer innovative ways to connect with Mt. Tam and parklands across the Bay Area. For updates, stay tuned to this newsletter, visit our website and follow us on Instagram and Facebook.

What’s happening this month? Read on to learn how we’re adapting the worldwide City Nature Challenge to the virtual realm, meet our newest staff member and get tips on staying connected from home.

Stay well. 

~ Your friends at One Tam

Together Apart: City Nature Challenge 2020

City Nature Challenge is a global community science event that calls on us all to connect with nature and virtually “collect” observations of trees, plants, birds and other critters using the iNaturalist identification app. Due to COVID-19, this year’s event has transformed from a competition to a world-wide, collaborative campaign celebrating the hyper-local biodiversity in our backyards and nature’s healing powers in this difficult time. 

We invite you to join us in the spirit of being “together apart” by downloading iNaturalist on your smartphone and taking as many observations as you can from April 24 –27th. Remember to follow local public health guidelines by keeping safe social distances and see how many types of trees, plants, birds and other critters you can find near or even inside your home. Any observations from Marin County will automatically be included in One Tam’s City Nature Challenge project on iNaturalist.

Naturalist Find: Ceanothus Silk Moth


Our iNaturalist observation of the mont was taken by Michelle Karle. 

This huge moth spotted near Muir Woods by iNaturalist user Michelle Karle is remarkable for its extravagant feathery antennae, which are used for smell. Adults moths do not feed and as larvae, they feed on Ceanothus, a group of native shrubs with beautiful purple or white flowers.
