Spotlights

  • USDA. Animal and Plant Health Inspection Service.

    The United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) confirmed the presence of virulent Newcastle disease in a small flock of backyard exhibition chickens in Los Angeles County, California. It is important to note that the presence of the disease is not a food safety concern. This is the first case of virulent Newcastle disease, previously referred to as exotic Newcastle disease, in the U.S. since 2003.

  • 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.
  • Tahoe Resource Conservation District; Tahoe Regional Planning Agency; DOI. Fish and Wildlife Service.
    Watercraft are the largest vectors for spreading aquatic invasive species (AIS), such as quagga and zebra mussels into new waterways, making boat inspections a vital aspect of protecting Lake Tahoe and other nearby water bodies.
  • Whatisthisbug.org (California).

    "What is This Bug" was developed from Farm Bill monies after the need for increased citizen help was recognized in the nationwide fight against invasive species. How can you help? Report a suspected pest. Now, with smartphones and the internet, new, easier and faster ways are available for reporting a suspicious pest, such as the Report a Pest Online Form and the Report a Pest Mobile App.

  • California Department of Food and Agriculture. Citrus Pest and Disease Prevention Program.

    The Asian citrus psyllid and citrus greening (Huanglongbing) could be a death sentence for California citrus trees - but with support from California residents, we can save the citrus trees that we all know and love.
