Dear Friend,

An uncommonly dry end to winter means fewer chances to enjoy the creeks and waterfalls around Mt. Tam, but it's also a reminder of the value of protecting our damp, vibrant redwood forests. 

Local fungi are typically fueled by rain around December and are maintained by continual moisture for the following months. This year things have dried out too quickly.  

“Pretty much the only place people seem to be finding mushrooms right now is in redwood forests," says Lisette Arellano, the Parks Conservancy's community science program manager for One Tam. "That just speaks to the need to protect those moist habitats for mushrooms and salamanders.”

The 2020 One Tam calendar offers a number of opportunities to learn about the challenges climate change presents for Tam and Marin, as well as ways to get involved in protecting our native plant and animals in our redwoods and beyond. Please join us on the mountain.

iNaturalist find of The Month: a glowing mushroom

Glowing Mushroom Composite

iNaturalist authority Damon Tighe captured these photos in Roy's Redwoods

This pedestrian-looking mushroom from the Gymnopilus genus, spotted in Roy's Redwoods, actually glows under UV light. Though the biological purpose of the glow is not clear, it's one more example of the facinating biodiversity of Roy's that One Tam partners are working to study and protect.

Februrary kicked off with hundreds of Bay Area residents spending a Saturday giving back to Mount Tam. The annual Hands on Tam event brought out a wide range of volunteers, including dozens of student-atheletes organized by the Marin County Bike Coalition.
