These data sheets are an adaptation of the IUCN supported Environmental Impacts Classification of Alien Taxa (EICAT) protocol for assessment of impacts of invasive species. A text version of the protocol is available in Hawkins et al. 2015 (see readme file). The data sheets provide a standard format for reporting and summarizing invasive species impacts.

The Chesapeake Bay Nutria Eradication Project (CBNEP) announced at an event at Blackwater National Wildlife Refuge today that Maryland is now free of the exotic, invasive nutria. The U.S. Fish and Wildlife Service (USFWS), U.S. Department of Agriculture’s Wildlife Services (WS), and Maryland Department of Natural Resources (DNR) have worked more than 20 years to make this difficult task -- never accomplished before on this scale -- a success.

This updated protocol is based on the National Wildfire Coordinating Group (NWCG)’s 2017 “Guide to Preventing Aquatic Invasive Species Transport by Wildland Fire Operations” (PMS 444). The intent of this NRCG guide is to provide a more prescriptive protocol intended for a fire management audience, and to increase compliance and consistency of best management practices related to preventing AIS. The protocol applies to both ground operations and aviation and is mandatory in the Northern Rockies region. This protocol is demonstrated via a “How to Guide,” which includes detailed instructions for ordering, set up, and assembly of AIS decontamination stations; options for products/equipment based on site specific conditions; and best management practices for drafting water, which can prevent the risk of most AIS being transported or spread via wildland fire equipment. Fire management agencies in the west are taking the threat of AIS seriously and have committed to decreasing the possible risk of introduction and spread by fire management personnel.

Forests are incredibly important to pollinators. Forest pollinators can also provide substantial economic benefits to neighboring agricultural areas, as a new global review paper discusses. Forest pollinators are easy to overlook – they are often highly seasonal, especially in temperate regions, and many are active far above our heads in the forest canopy.

The aim of this report was to identify the resources, strategies, and policies necessary to create, maintain, and make accessible one or more commodity/invasive species databases that EPA and other relevant agencies can apply to trade policy decision-making in a timely and scientifically-based manner.

The Maryland Department of Agriculture has confirmed the first spotted lanternfly hatch of 2020. The first instar nymph of the season was reported by a department employee while surveying for the pest in the upper northeast corner of Cecil County near the Pennsylvania border.

See additional resources on the Maryland Department of Agriculture's site for Spotted Lanternfly for up-to-date information.

The Maryland Department of Agriculture (MDA) expanded its spotted lanternfly quarantine.  A quarantine order first issued by the state secretary of agriculture in October 2019 for Harford and Cecil counties is still in effect, but has been expanded this year to also include: Anne Arundel, Baltimore, Carroll, Frederick, Howard, Kent, Montgomery and Washington counties, as well as Baltimore City. This quarantine is effective immediately, and restricts the movement of regulated articles that might contain the spotted lanternfly in any of its life stages, including egg masses, nymphs, and adults.

See additional resources on the Maryland Department of Agriculture's site for Spotted Lanternfly for up-to-date information. For questions related to the quarantine, permitting, treatment, or to report a sighting of the spotted lanternfly, especially outside of the quarantine zone, call 410-841-5920 or email DontBug.MD@maryland.gov. If you report a spotted lanternfly via email, please provide the location of the sighting and your contact information.

Farmers in the southeastern U.S. struggle with the invasive guava root-knot nematode, a microscopic roundworm, which infects and damages a variety of crops, particularly sweetpotatoes. To combat this worm, ARS researchers at the U.S. Vegetable Laboratory in Charleston, South Carolina, have identified a sweetpotato line from the agency’s expansive germplasm collection that has shown high levels of resistance to the guava root-knot nematode as well as resistance to other crop insects.

The Georgia Department of Agriculture (GDA) announced, in coordination with USDA and the University of Georgia, confirmation of the detection of a living yellow-legged hornet (Vespa velutina) in Savannah, Georgia. This is the first detection of a live yellow-legged hornet in the open U.S., which was confirmed on Aug 9, 2023. GDA is asking the public to report any sightings of the yellow-legged hornet, a non-native hornet species, that, if allowed to establish in Georgia, could potentially threaten honey production, native pollinators, and our state’s number one industry - agriculture. See more information about the yellow-legged hornet, including how to report sightings.

Distinguishing between non-native and native buckthorn is important so that management efforts can be targeted appropriately. This article desribes and separates the two invasive buckthorns from native alderleaf buckthorn.

Invasive species are notoriously challenging to track due to their ability to rapidly spread from one habitat to another, whilst their impacts on endangered species can be even more difficult to detect. Two new studies published in the journal Current Biology have now shown that it is possible to accurately identify a variety of animal species over distances of hundreds of metres by sampling environmental DNA (eDNA), or DNA traces shed by animals into the surrounding air.

Pursuant to the John D. Dingell, Jr. Conservation, Management, and Recreation Act (Public Law 116-9), the Department of the Interior (Interior) has released the final Interior-wide invasive species strategic plan. The Act became law on March 12, 2019. Title VII Section 7001 of the Act directs relevant Secretaries to take actions concerning invasive species. This includes the development of a strategic plan (Plan) in coordination with affected eligible States, political subdivisions of eligible States, in consultation with federally recognized Indian tribes, and in accordance with the priorities of Governors of eligible States.

The Plan sets out a vision for effectively managing invasive species through collaborative conservation to protect our nation’s environment and natural and cultural resources; economy and infrastructure; and public health. It both reflects ongoing work by Interior and its partners and leverages opportunities to respond to emerging issues.  This Plan will guide Interior’s work on invasive species in the next five years.

Officials at the U.S. Department of the Interior (DOI) announced in June 2017 that DOI would coordinate with the Western Governors' Association, states, tribes, federal agencies, and other partners in a project to help strengthen existing efforts to address invasive mussels. The actions described in the 2017 report, Safeguarding the West from Invasive Species, Actions to Strengthen Federal, State, and Tribal Coordination to Address Invasive Mussels [PDF, 1.3 MB], vary from policy and program reviews to on-the-ground efforts to prevent, contain, and control invasive mussels. One recommendation in Safeguarding the West was the development of a reference manual to facilitate rapid response activities in the event of mussel introductions in the Columbia River Basin. The U.S. Fish and Wildlife Service recently finalized and released this manual, Dreissenid Mussel Rapid Response in the Columbia River Basin: Recommended Practices to Facilitate Endangered Species Act Section 7 Compliance (Oct 2019) [PDF, 4.3 MB].

On Monday April 8, 2024, a total eclipse of the sun will be visible in a roughly 115 mile wide swath (called the path of totality) crossing North America as it passes over Mexico, the U.S., and Canada. Millions of travelers are expected to camp out over the weekend so they can be in the best viewing area on Monday to see the amazing spectacle of a complete solar eclipse. The Nature Conservancy is asking everyone that plans to use firewood for the solar eclipse celebration weekend to buy local firewood near their destination, bring packaged certified heat-treated firewood, or gather their firewood responsibly on site if permitted by the campground or landowner.

Early detection and rapid response (EDRR) is a key tenet of invasive species management, where “detection” is the process of observing and documenting an invasive species, and “response” is the process of reacting to the detection once the organism has been authoritatively identified and response options have been assessed.

The NISC FY 2020 - FY 2022 Work Plans identified priority activities in the area of rapid response, including:

• Rapid Response – Tools and Lessons Learned: Support national level rapid response efforts by documenting tools and lessons learned. NISC White Paper (Oct 2022) -- Rapid Response to Invasive Species: Federal Agency Roles [PDF, 577 KB]
• Rapid Response Fund - Criteria and Considerations: Increase resource streams for rapid response to new detections of invasive species. NISC White Paper (May 2022) -- Federal Invasive Species Rapid Response Fund:  Criteria and Considerations for Establishment [PDF, 823 KB]
