A very rare fern, Pumice Moonwart (Botrychium Pumicola), thought to be extinct in California (a small population exists near Crater Lake in Oregon), was recently discovered near treeline in Diller Canyon, on the slopes of the Shastina side of Mt. Shasta. This location is only about 4 miles or so east (and another mile up!) from the BBCRC. Apart from lumber company land, our site is one of the closest private pieces of property to the area where the fern grows. This discovery is further evidence of the unique ecology of this area.
