California & Baja California California Islands

Plants native to islands offshore of Alta and Baja California are featured in a section adjacent to the Baja garden. Biologists have used the flora and fauna of islands to study the evolutionary process since Darwin's visit to the Galapagos Islands. Isolation, lack of competition, and the novel environments of remote islands lead to the evolution of species that are often very different from their mainland counterparts. The more extreme the spatial isolation and the older the age of the island, the greater the differentiation between continental and island floras and faunas.
