The United States Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) has analyzed the potential environmental effects of establishing an integrated management strategy to control cogongrass in Alabama, Georgia, Mississippi, and South Carolina. The draft environmental assessment is now available for comment. Cogongrass is an invasive exotic grass found on public and private property, along roadways, in forests, and on farmland. This federally regulated noxious weed grows rapidly, reducing forest productivity, harming wildlife habitat and ecosystems, and encroaching on pastures and hayfields. Because of cogongrass' impact on agriculture and forest industries, Congress has given APHIS funding to partner with Alabama, Georgia, Mississippi, and South Carolina to control the spread of this weed. APHIS is proposing is an integrated management strategy that uses preventive, cultural, mechanical, biological, and chemical methods to control cogongrass in key areas of its distribution. APHIS invites the public to review and comment on this environmental assessment by April 1, 2020.

Today, the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) and Clemson University’s Department of Plant Industry (DPI) announced their plans for combatting the Asian longhorned beetle (ALB) in Charleston County, South Carolina. In June, APHIS and DPI confirmed the beetle is infesting trees in the county. The eradication strategy in South Carolina will be like those used for other ALB infestations in the United States. It includes establishing a quarantine, removing infested trees, and potentially using, with the landowner’s permission, a combination of tree removal and chemical treatment for trees that are within a half-mile radius of an infested tree.

If you live in the regulated area (PDF | 576 KB), please help by allowing officials access to your property to inspect and remove trees. If you live in Charleston County or nearby counties, please look for ALB and examine your trees for any damage that may be caused by the beetle, such as dime-sized exit holes in tree trunks and branches. Please take pictures and, if possible, capture suspicious insects in a durable container and freeze them, which helps to preserve the insect for identification. ALB is not harmful to people or pets. Report the insect or tree damage by calling the ALB hotline at 1-866-702-9938 or online at www.AsianLonghornedBeetle.com.

Firefighting personnel can unintentionally transport invasive species on clothes, gear, and equipment from the lower 48 to Alaska. They can also unintentionally spread invasive species within Alaska, from infested areas to clean areas. Aquatic invasive species can also be spread any time water is moved from an infested area to another waterbody, when seeds, propagules, or larvae are carried in small amounts of water or trapped in the water-handling equipment. This booklet is a tool to help identify some of the invasive species of greatest concern in Alaska and also suggests BMPs that will help firefighting personnel avoid introducing or spreading them. It also identifies four invasive species that should be reported to authorities and how to report them. See also: Invasive Plants Publications for more resources.

The green crab is considered one of the most invasive species in the marine environment. It has few predators, aggressively hunts and eats its prey, destroys seagrass, and outcompetes local species for food and habitat. Green crab could potentially damage Alaska’s multi-billion dollar fisheries industries, especially for salmon, crab, and mariculture operations. Thankfully, no green crabs have yet been detected in Alaskan waters, but concerned Alaskans have been planning for the arrival of these voracious crustaceans. There are three simple steps you can take to help find, remove and report these crabs on your local beaches. Find it, Keep it, Freeze it!

A draft integrated letter report and programmatic environmental assessment has been developed to determine the economic and environmental impacts of federal participation in state-managed watercraft inspection programs along the Upper Missouri River Basin in Montana, Wyoming, North Dakota, South Dakota and Nebraska. Public comments on the draft EA will be accepted until March 2, 2021.

The existing watercraft inspection programs are managed collaboratively by the states of Montana, Wyoming, North Dakota, South Dakota and Nebraska, where watercraft transported along highways are inspected for the presence of aquatic invasive species and decontaminated when detected. If approved, federal participation in the program would be cost-shared (50 percent) with each of the states, and would employ a regional strategy to identify locations that would provide the greatest likelihood of preventing the spread of aquatic invasive species to reservoirs operated and maintained by the Corps in the Upper Missouri River Basin.

The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is announcing its plans for combatting the Asian longhorned beetle (ALB) in Massachusetts, New York, Ohio, and South Carolina in 2021. "Every year, APHIS evaluates and determines the most effective options to achieve ALB eradication," said Osama El-Lissy, APHIS' Plant Protection and Quarantine Deputy Administrator. "Complete eradication of this pest from the United States remains our goal, and our strategy this year will advance our efforts to eliminate this pest from where it is infesting trees."

In 2021, the ALB program will focus on inspecting trees in quarantined areas in Massachusetts, New York, Ohio, and South Carolina, and removing infested trees at no cost to property owners. The program will not apply insecticide treatments this year. Program officials will monitor for the beetle's presence inside and around each area, respond to calls for assistance, conduct training sessions for compliance agreement holders, and perform outreach.

The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic H7N3 avian influenza (HPAI) in a commercial turkey flock in Chesterfield County, South Carolina. This is the first confirmed case of HPAI in commercial poultry in the United States since 2017. It appears this HPAI strain mutated from a low pathogenic strain that has been found in poultry in that area recently. No human cases of this H7N3 avian influenza virus have been detected and there is no immediate public health concern. All bird owners, whether commercial producers or backyard enthusiasts, should continue to practice good biosecurity, prevent contact between their birds and wild birds, and report sick birds or unusual bird deaths to State/Federal officials, either through their state veterinarian or through USDA’s toll-free number at 1-866-536-7593. Additional information on biosecurity for can be found at www.aphis.usda.gov/animalhealth/defendtheflock.

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 Utah County, Utah. This is the first case of virulent Newcastle disease in Utah. This case is believed to be connected to the current outbreak of virulent Newcastle disease in California, as three of the birds at the premises were recently moved to Utah from Los Angeles County, California. Since May 2018, 299 cases of Newcastle disease have been confirmed in Southern California, primarily in backyard exhibition birds.

Virulent Newcastle disease is not a food safety concern. No human cases of Newcastle disease have ever occurred from eating poultry products.
