San Joaquin County Environmental Horticulture
Welcome!
Landscape horticulture is an integral part of San Joaquin County's heritage and culture. Our mild climate and proximity to water provide abundant choices for growing a wide variety of beautiful plants. Our location at the head of the Delta also gives us a responsibility to manage our landscapes in sustainable ways that preserve the health and beauty of our waterways and wildlife for future generations.

ANR Research Clarifies Role of Tree Species in Air Pollution
Trees and shrubs help clean the air. They absorb carbon dioxide, release oxygen and provide surfaces for the deposition of airborne particles and unhealthful gases such as ozone. Also, water evaporating from tree leaves cools the air and shade from trees cuts energy consumption, reducing the need for air-polluting energy generation. However, there is another side to the story. Some trees and shrubs emit high rates of certain volatile organic compounds (VOC), which react with nitrogen oxides (NOx) and sunlight to form ozone, a ground-level pollutant. Other plants emit very little VOC.
