A.6. SUMMARY OF AQUATIC INVASIVE SPECIES MANAGEMENT IN CALIFORNIA 
A.6.1. AQUATIC INVASIVE SPECIES MANAGEMENT PLAN 
California Aquatic Invasive Species (AIS) Management Plan was approved in November 2007. 
A.6.2. AQUATIC INVASIVE SPECIES PROGRAMS AND ACTIVITIES 
• Aquatic Pest Control Program, California Department of Boating and Waterways 
(CADBW). This Program focuses on control of water hyacinth, Caulerpa taxifolia, and 
Egeria densa. The CADBW also uses annual hyperspectral aerial survey to monitor 
changes in infestations over time. The CADBW uses short- and long-term methods of 
water hyacinth control, involving chemical, mechanical, and biocontrol measures. The 
department also works with the California Department of Fish and Game on Caulerpa 
eradication efforts in southern California under the direction of the Southern California 
Caulerpa Action Team. Officials are also trying to educate aquarium owners on 
Caulerpa. The Egeria densa Control Program for the Delta focuses mainly on herbicide 
control. 
• Hydrilla Eradication Program, California Department of Food and Agriculture, 
Integrated Pest Control Branch. The program conducts annual surveys and eradication 
efforts for hydrilla. Eradication consists of physical, biological, and chemical methods. 
A.6.3. CLIMATE CHANGE CONCERNS 
• Aquarium owners may serve as vectors for Caulerpa spread. 
• Increased interstate transport as a result of climate change, such as opening of previously 
frozen waterways, may enable spread of AIS. 
A.6.4. CLIMATE CHANGE ACTIONS 
• Annual hyperspectral aerial survey should be used to monitor changes in infestations over 
time. 
• Educate aquarium owners about Caulerpa. 
• Implement prevention methods including quarantine regulations, inspection programs to 
ensure compliance with quarantine regulations, and border inspection stations to screen 
incoming traffic. 
• Work to detect invasive species using insect traps, manual inspections for exotic weed 
species, and/or surveys to determine size and boundaries of population.
