Pine Hill Preserve

Pine Hill Preserve chaparral plant communityLocated in western El Dorado County, Pine Hill Preserve is home to a collection of eight rare plant species.

Four of the plant species that grow in the Pine Hill Preserve are endemic, which means they grow nowhere else in the world. One species is nearly endemic, with only a few plants found elsewhere.  This assemblage of rare plants is part of a unique community confined to soils known as the Rescue soils, named after the nearby community of Rescue, CA.

These plants grow in a roughly oval area centering on Green Valley Road and stretching from Folsom Lake in the north to Highway 50 in the south. The entire preserve encompasses 4,746 acres under Federal, State and County ownership, and 3,362 of these acres are included in an area designated for the recovery of five federally listed plants.

Pine Hill Preserve's Rare Plants

Rescue soils have unusual properties derived from the underlying gabbro rock. They are generally red, mildly acidic, rich in iron and magnesium, and often contain other heavy metals.

Seven hundred distinct plant species have been recorded in the Rescue soil areas and the adjoining serpentine and metamorphic rocks. This means that about 10% of the native plant species in California can be found in this tiny fraction of the state!
