The green crab is an invasive marine species spreading throughout the coastal waters of the United States. Efforts between NOAA Fisheries and Metlakatla Indian Community have been leading the way on monitoring to detect this species’ presence in Alaskan waters. The green crab has been found in U.S. waters since the 1800s, but this is the first confirmed presence in Alaska. They are a serious threat for Alaska’s tidal habitats.

If you see an invasive green crab on Annette Islands Reserve, call (907) 886-FISH to make a report. If you encounter a potential green crab elsewhere in Alaska, take photographs from multiple angles and send them to Tammy Davis. Then submit a report to the Alaska Invasive Species Reporter, or call the Invasive Species Hotline: (877) INVASIV.

The United States Department of Agriculture (USDA) proclaims April 2024 as Invasive Plant Pest and Disease Awareness Month. During this month, we are encouraging everyone—whether you’re a gardener or a camper, a bug enthusiast or a student, a traveler, or an online shopper—to learn about the danger of invasive plant pests and what you can do to help. During the month, we are sharing information on curbing the spread of these pests to foster a healthier environment and protect our food supply.

Introduced on December 15, 2022 (117th Congress; 2021-2022), by Rep. Katie Porter [D-CA-45], this bill would create a coordinated domestic wildlife disease surveillance framework for State, Tribal, and local governments to monitor and respond to wildlife disease outbreaks to prevent pandemics, and for other purposes.

Provides situation summaries by type (wild birds, poultry, humans) and location.

The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) invites stakeholders to tap into their creativity and submit innovative proposals for fiscal year (FY) 2025 Plant Protection Act Section 7721 (PPA 7721) funding. APHIS is funding projects that protect American agriculture and natural resources this summer, and it’s time to apply! Applicants can submit suggestions for Plant Pest and Disease Management and Disaster Prevention Program funding from June 5 through July 31, 2024.

The Asian tiger mosquito can carry dread diseases like Zika, and yellow and dengue fever. After it vanished from Palmyra Atoll, an island in the tropical Pacific, USGS researchers and partners set out to find out why.

As communities continue to recover from widespread destruction caused by recent hurricanes Helene and Milton, floodwaters from these storms may have accelerated the spread of invasive wildlife and plant species into new areas.

This collection of publications in NAL's Digital Repository provides access to and addresses a number of topics concerning the gypsy and the related brown-tail moths, from biological control methods to tree banding to quarantine practices. The bulk of the documents were published from 1891 to 1923 by various agencies in the area of the initial infestation, including the State Board of Agriculture for Massachusetts, New York, and Rhode Island, but also include some more modern USDA publications.

Seeds that float in the air can hitchhike in unusual places – like the air-intake grille of a refrigerated shipping container. A team of researchers from the USDA Forest Service, Arkansas State University, and other organizations recently conducted a study that involved vacuuming seeds from air-intake grilles over two seasons at the Port of Savannah, Georgia. The viability of such seeds is of significant interest to federal regulatory and enforcement agencies, and the project required a shared stewardship approach. Their findings were recently published in the journal Scientific Reports.

Seeds from 30 plant taxa were collected from the air-intake grilles, including seeds of wild sugarcane (Saccharum spontaneum), a grass on the USDA's Federal Noxious Weed List. (scroll to view list on Federal Noxious Weeds Program). Federal noxious weeds pose immediate, significant threats to agriculture, nursery, and forestry industries. Although a lovely grass and useful in its native range, wild sugarcane has the potential to join cogongrass, stiltgrass, and other nonnative species that have become extremely widespread in the U.S.

In 2016 NASS began to collect data on honey bee health and pollination costs. Provides reliable, up-to-date statistics help track honey bee mortality.

Rodrigo Krugner, an entomologist with the Agricultural Research Service (ARS) in Parlier, California, has found an innovative way to control insect pests in California vineyards: tapping into the vibrational signals they use as mating calls.

Krugner’s efforts have mainly focused on glassy-winged sharpshooters, which spread a bacterium that causes Pierce’s disease in vineyards and costs the California grape industry an estimated $104 million a year. Growers use chemical sprays to control the pests, but insecticides also kill beneficial insects, leave residues, and become less effective as the insects develop resistance.

Changing climate conditions have bearing on every aspect of biological invasions, in some cases worsening existing problems. Climate change is creating new pathways for invasive species to be introduced, such as shipping routes that open up as sea ice retreats. Warmer temperatures can allow existing invasive species to expand their range into habitat that is currently too cool. Similarly, impacts to native species and people may change if new conditions affect invasive species abundance. Climate change may make existing invasive species control tools less effective, such as aquatic barriers that require minimum water flows.

In addition to intergovernmental efforts and research to detect and monitor aquatic nuisance species (ANS), the EPA addresses ANS using numerous regulatory tools.

The EPA's National Pollutant Discharge Elimination System (NPDES) Vessel General Permit (VGP) and Small Vessel General Permit (sVGP) regulate discharges incidental to the normal operation of commercial vessels, including ballast water and hull fouling, which are both pathways for introductions of aquatic nuisance species. The EPA and the Department of Defense are jointly developing the Uniform National Discharge Standards for vessels of the Armed Forces which will also regulate ballast water and hull fouling to help control the introduction of aquatic nuisance species.
