California Citrus Pest and Disease Prevention Program Continued for Another Four Years (Jul 30, 2013)
California Department of Food and Agriculture.
The California Department of Food and Agriculture has extended the California Citrus Pest and Disease Prevention Program for an additional four years. The extension came after several public hearings and a comment period that indicated overwhelming support for continuing the program among stakeholders. The program was created by legislation in 2009, establishing a mechanism for citrus producers to assess themselves to provide support for ongoing efforts to protect against citrus threats such as the Asian citrus psyllid. The psyllid is a pest that spreads the bacteria causing huanglongbing (HLB), or citrus greening, a fatal disease of citrus trees for which there is no cure.

UC Davis Scientists Assemble 5 Acres of Mats for Tahoe Asian Clam Project (Oct 16, 2012)
University of California - Davis.
Rubber barriers bound for the lakebed of Lake Tahoe's Emerald Bay are being assembled at the University of California, Davis, as part of the biggest Asian clam control project in the lake's history. The Asian clam control project is scheduled to begin on October 15 (weather permitting) and deployment of the bottom barriers will take from four to six weeks to complete. The barriers will be left in place for approximately one year in order to achieve clam mortality. Crews will return for three weeks in September-October of 2013 (after Labor Day) to remove the barriers. Work will primarily occur in early mornings to minimize interference with recreational boating; however, boaters entering Emerald Bay may be asked by on-site coordinators to delay their entrance into the bay for a short while to ensure diver safety. Work will only occur during the week, with no work occurring on the weekends or holidays, and has been scheduled not to interfere with the summer boating season. Boaters planning to visit Emerald Bay during these periods are asked to take extra precautions to avoid disrupting the control project or endangering the divers.

Citrus Disease Huanglongbing Detected in Hacienda Heights Area of Los Angeles County (Mar 30, 2012)
Citrus Research Board. Citrus Pest & Disease Prevention Program.
APHIS has confirmed the presence of citrus greening, also referred to as Huanglongbing, in an Asian citrus psyllid (ACP) sample and plant tissue samples collected from a lemon/pummelo tree in a residential neighborhood in Hacienda Heights, Los Angeles County, California. This is the first confirmation of the disease in California. APHIS is working closely with the California Department of Food and Agriculture (CDFA), County Agricultural Commissioners, and the California citrus industry to plan and implement communication, response, and regulatory activities in the affected area. CDFA collected the samples during ongoing citrus surveys conducted as part of the cooperative Citrus Health Response Program.
Note: CDFA has set up a hot line for residents who suspect they may have infected trees - (800) 491-1899.

CalWeedMapper
California Invasive Plant Council.
CalWeedMapper is a new Web site for mapping invasive plant spread and planning regional management. Users generate a report for their region that synthesizes information into three types of strategic opportunities: surveillance, eradication and containment. Land managers can use these reports to prioritize their invasive plant management, to coordinate at the landscape level (county or larger) and to justify funding requests. For some species, CalWeedMapper also provides maps of suitable range that show where a plant might be able to grow in the future. The system was developed by the California Invasive Plant Council  and is designed to stay current by allowing users to edit data. 

USDA Announces Additional Funding to Combat European Grapevine Moth in California (PDF | 39 KB) (Feb 24, 2012)
USDA. Animal and Plant Health Inspection Service.
USDA's Animal and Plant Health Inspection Service has announced the availability of $8 million in emergency funding to prevent the spread of European Grapevine Moth (EGVM) in California. The destructive moth was found in the Napa Valley of California in Oct 2009, which was the first occurrence of this moth in the U.S. and North America. EGVM is a serious pest of grape, feeding on the flowers and bunches. See European Grapevine Moth information from the California Department of Food and Agriculture for more information.
