Section 10 - Invasives and Pest Management

California Department of Food and Agriculture’s Plant Health and Pest Prevention Services (PHPPS)

The California Department of Food and Agriculture’s Plant Health and Pest Prevention Services (PHPPS) mission is to provide leadership of pest prevention and management programs that effectively protects California’s agriculture, horticulture, natural resources, and urban environments from invasive plant pests. In California, a series of federal and state plant quarantine laws and regulations are enforced to restrict the entry and movement of commodities capable of harboring targeted plant pests and to enable our eradication and control efforts. This approach of prohibiting or restricting the movement of plants, plant products or other commodities, capable of harboring exotic plant pests, is done in the interest of food security. In this case, the public insurance of a safe and secure food and fiber supply is based on the premise that it is more economically and environmentally sound to prevent the entry and establishment of dangerous plant pests than to live with them.

California Invasive Plant Council (Cal-IPC)

Cal-IPC's mission is to protect California wildlands from invasive plants through restoration, research and education. We work closely with agencies, industry and other nonprofit organizations to support research, restoration work, and public education.

Ecology and Society: Assessment and Management of Invasive Alien Predators

Although invasive alien species have been identified as the second greatest threat to biodiversity after habitat loss, characterizing and quantifying their impacts on native species and habitats remains a fundamental problem in conservation biology. Here, I review the techniques that are currently used to assess the impact of invasive alien species on biodiversity, highlighting both their uses in invasive species ecology and their limitations in establishing a causal relationship. Adopting a hypothesis-driven experimental approach to impact assessment, and to eradication efforts through adaptive management, would benefit our ecological understanding of invasive species without delaying critical management action that could reduce the spread of invasive species populations

ENVIRONMENTAL ASSESSMENT FOR THE RESTORATION OF SAN NICOLAS ISLAND’S SEABIRDS

and protect other native fauna, including federally and state listed threatened species, from population decline and potential extirpation or extinction. The U.S. Fish and Wildlife Service (USFWS) and Navy propose to restore and protect these species and injury to cats and foxes. Furthermore, a trap monitoring system would minimize the time animals are held in traps prior to release (foxes) or euthanasia (cats). The USFWS and Navy propose to use padded leg-hold live trapping as the primary eradication method. Hunting with and without specialized dogs would be used strategically as a supplemental method. their habitat by eradicating feral cats from the island. The most common techniques used globally for eradicating feral cats from islands are trapping, hunting, and poisoning. The presence of the San Nicolas island fox, however, restricts the available techniques in this case, making poisoning infeasible. The Proposed Action is to use a combination of trapping and hunting through integrated adaptive management to eradicate feral cats from San Nicolas Island. A field study on San Nicolas Island conducted in 2006 demonstrated that padded leg-hold live traps can be used to trap feral cats effectively with minimal
