The U.S. currently spends approximately $120 billion annually on the control and impacts of invasive species. Once established in natural areas, invasive plants displace native vegetation and greatly reduce wildlife diversity. In addition, invasive plants fuel wildfires, degrade grazing land, contribute to soil erosion, clog streams and rivers, increase flooding, and have negative impacts on our local water supply.

As part of the Council for Watershed Health's Strategic Plan, this section of our site is dedicated to increasing the level of awareness and cooperation with regard to these issues within the greater Los Angeles Region. The Weed Watch program highlights our current monitoring and outreach accomplishments as well as other local, regional, and statewide efforts focused on the spread, control, and education of invasive plants.
