Upcoming Events

Botanical Hotspots of Northern California

Northern California is among the most diverse floras of the world and much of that diversity is found in well defined hotspots. In May and July Glenn Keator offers this series of free presentations from 10 AM to 12 PM at the Botanic Garden Visitor Center.

May 31 SNOW MOUNTAIN WILDERNESS The Snow Mountain Wilderness straddles the summit of the North Coast Range within Colusa, Glenn and Lake counties. The central feature of this wilderness is the large broad topped Snow Mountain, which drains water toward the Sacramento River on the east and the Eel River Basin on the west. The deep canyons skirting the Wilderness compress ecological life zones creating a unique biological sky-island.

July 12 THE SMITH RIVER WATERSHED California’s most northern undammed river feeds into wetlands and sea promontories and extends into deep forested canyons with peaks rising to 5,000 feet and is home to many special endemics.

July 19 COOK AND GREEN PASS Just short of the Oregon border, 5000-foot Cook and Green Pass has an unparalleled diversity combining lowland species with high and subalpine species in a series of forests, meadows, and rock outcrops.

July 26 MT. EDDY This, the highest point in the Klamath Mountains at 9,000 feet is an entirely serpentine area featuring several gem like lakes, large meadows, a range of interesting conifers, and true alpine habitat. It is also home to vast populations of the curious insectivorous cobra plant, Darlingtonia californica.
