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.

Terrestrial invasive plants are expected to shift their ranges in response to changing climate. This tool provides lists of terrestrial invasive plants expected to expand their ranges into the chosen county or state with climate change by 2040-2060. Users can filter the list to species currently observed within a chosen geographic proximity to the focal county or state.

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]

A worm is a worm is a worm, right? Except that there are more than 7,000 species of worms, and the longer you look, the more complex their world becomes. Earthworms compete. Earthworms invade. Earthworms… jump?

The Pennsylvania Fish and Boat Commission (PFBC) announced that it has conducted targeted invasive carp sampling in Presque Isle Bay, Erie County, after the U.S. Fish and Wildlife Service (USFWS) detected the presence of Silver Carp environmental DNA (eDNA). While no physical invasive carp specimens have been detected, the PFBC has requested that the USFWS collect additional water samples from Presque Isle Bay in the fall when more favorable environmental conditions are present for eDNA sampling. Members of the public can report sightings of aquatic invasive species to the PFBC using its online form.

Environmental DNA (eDNA) has gone from new science on the block to a star of the show. With just a water, soil, or snow sample, ecologist Tommy Franklin and fellow scientists at the Rocky Mountain Research Station are detecting rare aquatic and terrestrial species by identifying the genetic material they leave behind.

Scientists at the Rocky Mountain Research station recently used eDNA to preserve headwater bull trout populations in a warming climate, track white nose syndrome — a killer bat fungus, and reveal the role of human transport in the spread of invasive northern pike in the Columbia River basin. A recent article highlights eDNA research at the station and features National Genomics Center Director Mike Schwartz.

Environmental DNA is developing into a powerful tool for improving the monitoring and detection of invasive species, which may be present in low numbers and therefore difficult to find. There are a wide range of ongoing efforts by federal and non-federal groups working to improve and apply eDNA to invasive species monitoring and management.

The NISC FY2020 to FY2022 Work Plans incorporated interagency work on eDNA, including the following outputs:

• The NISC white paper has been released (May 2022): Environmental DNA as a Tool for Invasive Species Detection and Management [PDF, 295 KB]

Assays of environmental DNA — traces of genetic material found in air, soil, and water — may improve scientists’ ability to detect bat roosts and track the spread of white-nose syndrome, a disease caused by a killer fungus spread easily in the close quarters of hibernacula. In this research, scientists experienced success in detecting bats in field collected samples of environmental DNA, though the technology is still in the experimental stage.

The 20-year fight against plum pox – a serious agricultural disease capable of devastating stone fruits like peaches, apricots, cherries, and almonds – is finally over, thanks to a cooperative effort by the Agricultural Research Service and their partners.

Whether called wild pigs, feral hogs, or wild boars, these opportunistic and invasive omnivores live in groups called sounders. Removing whole sounders is the most effective management method, but requires follow-up trapping and hunting due to their incredible reproductive potential.

Next-generation laboratory gives USDA scientists the ability to expand research established at Plum Island. Scientists have been helping other countries in a united front against foreign animal diseases. These efforts also help the U.S. prepare for and prevent a potential introduction of a high-consequence livestock disease. African swine fever virus, or ASFV, is among the most concerning animal disease pathogens currently circulating the globe. While the pathogen doesn’t affect humans and has not been seen in U.S. swine, it is economically affecting the pork industry.

Scientists and staff at the Agricultural Research Service have been studying Covid-19 for over a year-and-a-half to ensure that America’s agricultural system is safe. The aim of the research was to confirm that farm animals were not susceptible to the SARS-CoV-2 virus and remove potential concerns of farm animals becoming infected and transmitting the virus to people through direct contact or through agricultural products.

The second annual National Pesticide Safety Education Month gets underway February 1st, to reinforce core principles of safe handling and use and to raise awareness of and support for the land-grant university Pesticide Safety Education Programs (PSEPs). Pesticide safety is a must, whether the applicator is an unlicensed homeowner or certified in one or more of the federal or state categories of use.

The U.S. Fish and Wildlife Service and U.S. Geological Survey have signed a memorandum of understanding formalizing their joint leadership of the North American Bat Monitoring Program (NABat), a collaborative partnership focused on advancing bat conservation across North America. As co-leads of the NABat program, the two federal agencies will work to ensure the program remains sustainable and meets the needs of partners by providing coordination, technical assistance, data products and analyses that make it easier to apply bat monitoring data more effectively in support of conservation. For more information about the North American Bat Monitoring Program and opportunities to participate, please visit https://www.nabatmonitoring.org.

NABat was born out of the urgent need to monitor bat populations following the emergence of white-nose syndrome, a disease of hibernating bat species that appeared in New York in 2007 and has since spread across the continent. White-nose syndrome is considered one of the worst wildlife diseases in modern times, resulting in the loss of millions of bats across North America.

All known feral swine have been eliminated from Colorado thanks to a near 15-year state and federal partnership comprised of the U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) Wildlife Services (WS), the USDA Forest Service (FS), Colorado Parks and Wildlife (CPW) and the Colorado Department of Agriculture (CDA). The partnership formed in the early 2000s as a task force to manage invasive feral swine, which root up crops and pastures causing billions in damage nationwide each year. Feral swine also spread disease to livestock, wildlife and humans. Ground-nesting birds and other wildlife are easy prey for feral swine. And the swine put native wildlife at risk by competing for resources and destroying habitats and ecosystems. 

You can help keep Colorado free of feral swine:

• Spread the word that in Colorado it’s illegal to possess, transport or release feral swine, wild swine species or hybrids.
• Report sightings of feral swine or transportation activities to USDA Wildlife Services at 1-866-4-USDA-WS (1-866-487-3297) or Colorado Parks and Wildlife at 303-297-1192.
• Get more information at the National Feral Swine Damage Management Program.
