Invasive Species - What's New on NISIC's Site

The United States Department of Agriculture's (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed highly pathogenic Eurasian H5 avian influenza (HPAI) in a wild American wigeon in Colleton County, South Carolina. Eurasian H5 HPAI has not been detected in a wild bird in the United States since 2016. There was a case of HPAI (H7N3) in one commercial meat turkey flock in South Carolina in 2020 due to a North American lineage virus. The Centers for Disease Control and Prevention considers the risk to the general public from HPAI H5 infections to be low. No human infections with Eurasian H5 viruses have occurred in the United States. As a reminder, the proper handling and cooking of poultry and eggs to an internal temperature of 165˚F kills bacteria and viruses, including HPAI.

Anyone involved with poultry production from the small backyard to the large commercial producer should review their biosecurity activities to assure the health of their birds.

The Michigan departments of Environment, Great Lakes, and Energy and Natural Resources confirmed a report of didymo, a nuisance freshwater alga, in a stretch of the Upper Manistee River in Kalkaska County. Also known as rock snot despite its coarse, woolly texture, didymo can grow into thick mats that cover the river bottom. The Manistee River finding marks the first detection of didymo blooms in the Lower Peninsula. In 2015, extensive mats of didymo were found on the Michigan side of the St. Marys River near Sault Ste. Marie in the Upper Peninsula.

If you observe didymo in the water, either as small, cotton ball-sized patches or thick blankets with rope-like strings that flow in currents, take photos, note the location and report it by using the Midwest Invasive Species Information Network, available online at MISIN.MSU.edu or as a downloadable smartphone app. The MISIN smartphone app will take a GPS location point if a report is made at the site; it also will allow you to upload photos with a report. Find more information on didymo and how to identify it at Michigan.gov/Invasives.

ARS researchers created a new tool, called Pathogen and Tree Fruit Health Map (PATHMAP), which will connect growers in different states and allow them to share important data regarding tree fruit diseases, disorders, and insect pests. This online interactive tool will enable growers to modify and adjust their pathogen and pest control programs based on real-time data, provide quick access to time-sensitive data, give them access to experts in the field, and provide access to previous years observations and track current diseases, disorders and pests.

Provides watercraft inspection and decontamination state information in the western states and Canadian provinces to prevent the spread of aquatic invasive species.

In December 2021, the Pacific States Marine Fisheries Commission (PSMFC) initiated a program to prevent delays during the transport of watercraft destined in the Pacific Northwest.

Coastal marshes that have been invaded by feral hogs recover from disturbances up to three times slower than non-invaded marshes and are far less resilient to sea-level rise, extreme drought and other impacts of climate change, a new study led by scientists at Duke University and the University of Massachusetts Boston (UMB) finds. "Under normal circumstances, marshes can handle and recover from drought or sea level rise, given time, but there is no safety net in place for hog invasions," said Brian Silliman, Rachel Carson Distinguished Professor of Marine Conservation Biology at Duke, who co-authored the study.

Pigweed is a major challenge to our farmers and growers. It is extremely resilient and resistant to many herbicides, posing a significant threat to the agriculture industry. ARS scientists in Stoneville MS, along with collaborators from Clemson University, are researching the pigweed itself to find ways to mitigate this highly adaptable weed.

In a letter [PDF, 396 KB] to the Chairs and Ranking Members of the U.S. Senate Committee on Environment and Public Works and the U.S. House Committee on Transportation and Infrastructure, the Governors of the eight Great Lakes States have called on the U.S. Congress to provide full federal funding in the 2022 Water Resources Reform and Development Act for the remaining design, construction, operation, and maintenance costs of the Brandon Road Lock and Dam project. The project is intended to prevent invasive carp from migrating up the Mississippi River and entering and colonizing in the Great Lakes.

A newly signed project is set to provide pilot projects in developing countries in order to demonstrate technical solutions for biofouling management, address the transfer of invasive aquatic species and help reduce greenhouse gas emissions from ships. Biofouling is the accumulation of aquatic organisms on wetted or immersed surfaces such as ships and other offshore structures.

The project complements the existing Global Environment Facility (GEF)/United Nations Development Programme (UNDP)/IMO GloFouling Partnerships Project, which aims to support its lead partnering and partnering countries to implement IMO's Biofouling Guidelines [PDF, 134 KB].

As part of President Biden’s whole-of-government approach to confronting the climate crisis, the U.S. Department of Agriculture (USDA) released its climate adaptation and resilience plan describing how USDA will prepare for current and future impacts of climate change. The Adaptation Plan is aligned with a renewed and broad effort across USDA to prioritize climate action and increase resilience to climate impacts among American producers, landowners, and communities. For details of the plan, see Action Plan for Climate Adaptation and Resilience (Aug 2021) [PDF, 813 KB].

The U.S. Department of Agriculture, Animal and Plant Health Inspection Service (APHIS) has prepared an environmental assessment (EA) to issue permits for the release of the insect Lophodiplosis indentata (Diptera: Cecidomyiidae) to biologically control Melaleuca quinquenervia (Myrtaceae) in the continental United States. Based on the environmental assessment and other relevant data, APHIS has reached a preliminary determination that the release of this control agent within the continental United States will not have a significant impact on the environment.

The proposed action is intended to reduce the severity of environmental damage to wetlands from the invasive Melaleuca tree in the continental United States. Melaleuca is native to Australia, New Caledonia, and Papua New Guinea and was imported into Florida in the late 19th century. It has since established in Florida’s wetlands, dramatically disrupting normal water, fire, disturbance recovery, and nutrient cycles—as well as impacting the amount of light available to other plants. APHIS is making the environmental assessment available to the public for review and comment. All comments received on or before Jan. 16, 2022 will be considered.
