Join Don Thomas for a 3 to 4 mile hike with 500+ feet in elevation change, to search for the elusive Western leatherwood at Pulgas Ridge OSP near Edgewood Road. Western leatherwood (Dirca occidentalis) is a rare paleoendemic plant native only to the San Francisco Bay Area, ranked by CNPS as 1B.2. (Read more about CNPS rare plant ranks at www.cnps.org/rare-plants/california-rare-plant-ranks.)
Dirca is one of our earliest flowering native plants, blooming in mid-to-late winter before most other natives begin blooming in the spring. We will look for late- flowering Dirca along the Dusky Woodrat Trail. We may be able to observe other early-blooming plants, such as manzanitas and gooseberries.
