We got some nice feedback on our mention of Mariposa Trails in our last post, and so it is only fair to highlight another great group that is doing wonderful work in the Sierra--this one just a bit north of Mariposa.
CSERC is the Central Sierra Environmental Resource Center--a science-based group that works with a wide range of stakeholder groups to chart a reasonable and healthy path forward for the Sierra that we love so much. They do research, advocacy, education, and yes, trail/restoration work in the Sierra around Yosemite and the Stanislaus National Forest. The photo above is from one of their wildlife cams...
Here's a link to their website.
Check it out. Surely you can find something there that you want to do, or want to support.
