The University of California, Irvine's Arboretum has evolved and will see many exciting improvements during the coming months. The new role in the Ayala School of Biological Sciences and mission emphasis will be upon encouraging and assisting teaching and research. Although the facility will be closed to unscheduled public visitation, there will be an open house each quarter at which there will be public Arboretum and Marsh Tours, and during which researchers using the Arboretum will showcase their studies and research sites for the public. These events will be well publicized, posted on our website, and will be held during times of peak flowering in various of our exhibits, particularly the South African Bulb Garden and aloe exhibits.

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.
