Endemic Plants are the plants that grow at The Cedars and nowhere else in the world. Roger Raiche was responsible for the discovery of several plants at The Cedars including The Cedars’ Manzanita, The Burgundy-Leaf Stream Orchid, The Cedars’ Buckwheat, The Cedars’ Oceanspray, and The Cedars’ Fairy-Lantern, Calochortus raichei, later named in Roger’s honor. These plants likely adapted from past widespread species into new species that have adapted to the conditions at The Cedars.
Disjunct and Extralimital Plants are the plants that are at their extreme limits at The Cedars, such as the south-most population of Cotton-grass and its only known station in Sonoma County. Many of these types of plants are thought to have been widespread in the past. Various effects, like changing climates, are thought to have contributed to the plants retreating to specialized habitats like The Cedars.
Additional Important Plants include the most common trees and plants seen at The Cedars, like Sargent Cypress, for which the place name of The Cedars more than likely stems. There are more
than 260 types of plants that grow at The Cedars. This book shares only a sampling of the incredible plant diversity of the 5500 acres of serpentine wilderness at The Cedars.
Ultra-Basic Springs and More Treasures The presence of ultra-basic springs (pH <11) at The Cedars indicates that the serpentinization process continues today. These waters are the subject of ongoing scienti c investigations. The larger creek and canyon ecosystems support a wide variety of life.
