4	How can landscaping contribute to air quality problems? Some trees and landscaping plants emit Volatile Organic Compounds or VOC’s. VOCs are a component chemical for the creation of ground level ozone pollution. Trees and plants that produce cones, called conifers are particularly high in VOC production. Other trees high in VOC include Live Oak and Pecan. Planting air friendly trees and plants reduce VOCs and reduce pollution. Planting native species or Smartscaping contributes to clean air by reducing the need to water. Producing water uses electricity. Reducing electricity usage is good for the air.
5	So what trees are good for the air? This presentation highlights native Texas trees that are good for Texas air. Enjoy the photos and information.
