About the ESA
The Cheeseman Environmental Study Area is located next to the Kirsch Center for Environmental Studies on the southeast corner of the De Anza campus. It's a lush natural garden containing some 400 species of plants representing 12 California natural communities. In addition to the native plant communities, there is a xeric native plant display at the entrance.
California's Biological Richness
California is a naturalist's paradise. Our state has hundreds of habitat types and plant communities, with more than 5,000 species of native plants. You can experience many of these special wonders with a walk through our 1.5 acre garden.
At least a third of California's native species are found naturally nowhere else on Earth. California's plants support nearly 1,000 vertebrate animals-fish, amphibians, reptiles, birds and mammals. Among animals as a whole, including insects and other invertebrates, at least 50% of the species and subspecies are found only within our state. In short, we are very fortunate to live in such a biologically vibrant place!
