Quagga mussels were discovered in Lake Mead in Nevada on Jan. 6, 2007, and later throughout Lake Mead’s lower basin. It was the first discovery of either of these mussels west of the Continental Divide.

The rich soils and moderate climate of Monterey County make it an ideal place for invasive weed species to colonize. Invasive weeds are usually able to out-compete local native plant species for water and space because they are more prolific, have more vigorous growth, and lack predators that would otherwise help to keep them in check.

Louanne McMartin is the Pacific Southwest Assistant Regional AIS Coordinator for the U.S. Fish and Wildlife Service’s Aquatic Invasive Species (AIS) Program.

WMAs are local stakeholder groups working on weed projects. Typically, they are organized by county, through county Agricultural Commissioners' offices.

Cal-IPC protects California’s environment and ecology from invasive plants. As a leader in land management, we coordinate regional partnerships, design science-based tools and projects to remove invasive plants, train volunteers and professional land stewards, and advocate for sound public policy and funding.

The Biological Control Program is a unit within the Integrated Pest Control Branch, and an integral part of the Department's Division of Plant Health and Pest Prevention Services.

The California Department of Food and Agriculture (CDFA) established the Beet Curly Top Virus Control Program (BCTVCP) in 1943 to manage the economic impact of beet curly top virus (BCTV) throughout the State in accordance with California Agricultural Code, section 6031-6043.

The Program is a statewide effort to detect the highly invasive weed hydrilla and mitigate its spread by quarantine and eradication methods.

One of the premier activities that the AIS coordinators have worked on with public and private entities is the 100th Meridian Initiative. The goal of the Initiative is to prevent the spread of aquatic invasive species by boats personal watercraft and other pathways.

The mission of the Invasive Species Program is to reduce the negative effects of non-native invasive species on the wildlands and waterways of California.

The University of California Statewide IPM Program (UC IPM) helps residents, growers, land managers, community leaders, and other professional pest managers prevent and solve pest problems with the least unintended impacts on people and their surroundings.

The Center for Invasive Species Research based on the University of California Riverside Campus provides a forward-looking approach to managing invasions in California by exotic pests and diseases.

RiversEdge West (formerly Tamarisk Coalition) was founded in 1999. RiversEdge West focuses on riparian forest and floodplain health in the American West to address impacts from invasive riparian (riverside) plants such as Russian olive and tamarisk, challenges associated with climate change and habitat fragmentation, and stressors that may result in diminished biodiversity and ecosystem services.

The mission of WAPMS is to serve as a chapter of the Aquatic Plant Management Society (APMS) organization, providing a forum for members in Western North America to share interdisciplinary information related to aquatic plant and algae identification, detection, management and control.

Aquatic invasive species (AIS) (sometimes called exotic, invasive, nonindigenous or non-native) are aquatic organisms that invade ecosystems beyond their natural, historic range.
