California's environment is characterized by vast extremes and great biodiversity. It ranks near the top among the 50 states in nearly every category of biodiversity. It is under extensive pressure due to global climate changes and increasing population and development.

Each resource theme is subdivided into six sections: 1) guides and bibliographies, 2) general introductions, 3) environmental history, 4) data compilations, 5) reviews and assessments, and 5) maps
