APHIS Adds Del Norte County in California to Phytophthora ramorum Quarantine Area (May 21, 2021)

USDA. Animal and Plant Health Inspection Service.

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is expanding the Phytophthora ramorum (P. ramorum) quarantine area in Del Norte County, California. APHIS is taking this action in response to the confirmation of P. ramorum in the county on September 19, 2020. The California Department of Food and Agriculture has established an intrastate quarantine for the areas in Del Norte County that mirrors the federal regulatory requirements as specified in 7 CFR 301.92.

P. ramorum is the pathogen that causes sudden oak death, ramorum leaf blight, or ramorum dieback. Sudden oak death was first reported in 1995 on tan oak in Mill Valley, Marin County, California. Through ongoing surveys, APHIS continues to define the extent of the pathogen's distribution in the United States and uses quarantine areas and public outreach to limit its artificial spread beyond infected areas. Details on APHIS-designated P. ramorum quarantine and regulated areas and the conditions to move regulated articles are in 7 CFR 301.92 and at the APHIS website.

APHIS Expands the European Cherry Fruit Fly (Rhagoletis cerasi) Quarantine to include all of Monroe and Wayne Counties, New York (May 28, 2021)

USDA. Animal and Plant Health Inspection Service.

Effective May 11, 2021, the Animal and Plant Health Inspection Service (APHIS) and the New York State Department of Agriculture and Markets (NYS AGM) expanded the European cherry fruit fly (ECFF) quarantine to include all of Monroe County and Wayne County and a small portion of northwestern Ontario County, New York. With this expansion, the ECFF quarantine now includes all of Erie, Monroe, Niagara, Orleans, and Wayne Counties. This action is necessary to prevent the spread of ECFF to non-infested areas of the United States, while maintaining commercial cherry production and marketing within the state. The APHIS website reflects the expansion of this quarantine and contains a description of all the current federal fruit fly quarantine areas.

APHIS Updates the Golden Nematode (Globodera rostochiensis) Regulated Area in Suffolk and Nassau Counties in New York (Aug 24, 2021)

USDA. Animal and Plant Health Inspection Service.

Effective immediately, the Animal and Plant Health Inspection Service (APHIS) is removing 45,562.067 acres from the golden nematode (GN) regulated area in Suffolk County, New York and refining the global positioning system (GPS) points for the descriptions of the regulated area in the town of Oyster Bay in Nassau County, New York. APHIS is removing these areas based on survey results and other criteria in the "Canada and United States Guidelines on Surveillance and Phytosanitary Actions for the Potato Cyst Nematodes, Globodera rostochiensis and Globodera pallida”.

Since 2010, APHIS, working closely with the New York State Department of Agriculture and Markets (NYS AGM), has removed 1,186,693.79 acres from the GN-regulated area in New York. APHIS and NYS AGM have an active control and mitigation program in place to prevent GN from spreading from the remaining 101,955.27 acres, including 5,945 GN-infested acres in eight New York counties. The specific GN-regulated areas are on the APHIS website.

Boating - Permits & Inspections
DOI. NPS. Yellowstone National Park.
If you plan to use your own boat or angler float tube, you’ll need a permit and a free Yellowstone aquatic invasive species inspection. You can speed up the inspection process by arriving with a boat that is clean, drained, and dry. Watercraft that arrive dirty or with standing water will be subject to decontamination. Watercraft that cannot be properly decontaminated will be prohibited from launching.
European Grapevine Moth Cooperative Eradication Program: A Model for Fighting Future Invasive Species Threats (Nov 2, 2016)
USDA. Blog.
Key partners and contributors in Napa County, California, recently celebrated and recognized the critical safeguarding accomplishment achieved together, of eradicating the invasive European grapevine moth (EGVM) from the U.S. The keys to success were early detection, our rapid response, and a strong collaboration between federal, state and local officials, growers, university scientists and extension services. Such partnerships remain critical to our ability to safeguard agriculture and facilitate safe trade.
