Dear Friend,

As our parks reopen and visitors return, many are seeking the restorative qualities of nature. 

During these times of pandemic, isolation, and protest, humans have an opportunity to better appreciate the life-giving resilience we share with the rest of the natural world. 

Nature's ability to recover from floods and fires is remarkable. But changing conditions brought about by climate change, rising seas, drought, and disease, are testing the resilience of Marin’s native species and unique ecosystems.

The partner agencies at One Tam are actively working to support the continued health of our forests, hillsides and coastlines as these conditions change. Some of our most important project work this year centers around forest resilience. 

You may have seen work underway on the mountain recently. One Tam Partners are using demonstration sites to test methods of improving forest health and biodiversity while reducing fuel loads which contribute to wildfires. When complete, this work will result in a Forest Health Strategy that can be used to improve resilience across Mt. Tam. Please visit our website for background and updates on this work. 

~Your friends at One Tam

  • Interested in understanding how the justice movement intersects with our public lands? Our partners at the Parks Conservancy have a list of resources to help gain understanding and combat racism in public spaces. 
  • This exceptional video series from the California State Parks and Peninsula Open Space Trust provides a valuable overview of Bay Area indigenous history prior to the arrival of Europeans. 
  • For those using art as an outlet, our friends as the River Otter Ecology Project are hosting a competition around the theme of water. Show off how the natural world has inspired you. 
  • Our park closure map has turned very green in recent weeks, meaning nearly every public park managed by our partners is at least partially open to vehicle traffic. Monitor for continued updates.

Naturalist Find: Pale Swallowtail Butterfly 


Our iNaturalist observation of the month was captured and uploaded by user Tom Brookshire

The leopard lily and pale swallowtail butterfly are signs of summer on Mt. Tam. They both sip water and nutrients from moist soil as they prepare for reproduction. Pale swallowtail butterflies gather around puddles to drink and the males exhibit a behavior called hill-topping, in which males compete for mates and territory at high points on the landscape. Leopard lilies grow from a bud up to eight feet tall and produce distinctive dark orange blossoms with brown spots that attract pollinators.
