Join us for a very special outing to the Channel Islands!

With an area of 84 square miles, Santa Rosa is the second-largest of the eight California Channel Islands. The island’s flora is comprised of just under 400 native taxa and about 100 non-native taxa. At least 37 of the native taxa are restricted to two or more of the California Islands. Six taxa are now found only on Santa Rosa Island, including a manzanita (Arctostaphylos confertiflora), two live-forevers (Dudleya blochmaniae subsp.insularis andDudleya gnoma), a gilia (Gilia tenuiflora subsp.hoffmannii),a paintbrush (Castilleja mollis), and a pine (Pinus torreyana insularis).

This three-day trip will familiarize participants with Santa Rosa Island’s diverse flora, especially the endemic taxa. We will be exploring the island’s pristine beaches and coastal terraces on foot and will have a chance to learn about the history of land use and botanical exploration, the island’s major plant associations, and recognition of common plants. Hiking will be moderate to moderately strenuous, so participants should be in good physical condition. We will be staying at the very comfortable Cal State Channel Islands field station at the historic Vail Ranch.
