Tree Guidelines for Inland Empire Communities

Abstract

Communities in the Inland Empire region of California contain over 8 million people, or about 25% of the state’s population. The region’s inhabitants derive great benefit from trees because compared to coastal areas, the summers are hotter and air pollution levels are higher. The region’s climate is still mild enough to grow a diverse mix of trees. The Inland Empire’s climate is influenced by the ocean less than 15% of the time and extends from Ojai east to Simi Valley, Glendale, Alhambra and Riverside, as well as south to Escondido.
