Today, Environment Minister Dustin Duncan introduced the Government of Saskatchewan’s new Aquatic Invasive Species Strategy during an address to the Saskatchewan Wildlife Federation’s (SWF) annual convention in Weyburn. The new framework is designed to help the province prevent, address and manage aquatic invasive species (AIS) threats. The ministry and the SWF are partners on the province’s AIS Task Force – which focuses on additional education and monitoring activities – along with other government agencies, conservation groups, non-government organizations and universities. "This strategy emphasizes the need for collaboration and co-ordination with provincial and federal government agencies, non-government organizations and neighbouring jurisdictions to prevent the introduction and spread of high-risk aquatic invasive species," Duncan said.

ITP is pleased to announce that Sawfly GenUS is now complete. Developed in cooperation with the Washington State Department of Agriculture, Sawfly GenUS is an interactive identification tool for all sawfly genera found in the United States and Canada. This tool is intended to help recognize exotic sawfly introductions and provide access to general information on affected plants, range, and diversity of these insects. This tool should be useful for port identifiers and screeners, provincial and state departments of agriculture, university extension professionals, and any non-expert with an interest in sawflies.

For more than 30 years, the U.S. Fish and Wildlife Service has worked with Vermont and New York to control this invasive species and protect Lake Champlain. Fortunately, sea lamprey woundings are now at an all-time low.

The U.S. Geological Survey provides natural-resource managers with scientific information, risk assessment, and tools that can help to improve surveillance, prevention, and control strategies for managing invasive carp.

The plot could have come from Hollywood — an insidious alien invader threatens to overrun the land, but intrepid scientists discover a secret weapon in the far-off, exotic land of Nepal and bring the pestilence to heel. But this is not fiction; it's true. The air potato plant (Dioscorea bulbifera) is an exotic vine from Asia that was introduced to Florida about 115 years ago to make medicine. After escaping from the lab, it multiplied and smothered native plant communities in all of Florida's 67 counties. It spread beyond to large swaths of land in the southeastern United States. All attempts to manage the air potato – mechanical, chemical, or physically gathering the bulbils — were unsuccessful; they were either too labor intensive and costly or caused collateral damage to native and endangered species. According to Min Rayamajhi, a plant pathologist at the Agricultural Research Service's (ARS) Invasive Plant Research Laboratory (IPRL) in Fort Lauderdale, FL, the vines return every season, repeating the growth cycle and expanding the invasion at a rate of about 6 inches per day. Rayamajhi and retired ARS scientist Bob Pemberton traveled to Nepal and accidentally discovered the air potato beetle.

Biologists from the U.S. Geological Survey are racing the clock to pull four species of native Hawaiian Honeycreeper forest birds back from the brink of extinction. Factors such as habitat loss, invasive species, and non-native predators have been fueling the birds' decline for centuries. However, introduced diseases, particularly avian malaria spread through mosquitos, which are not native to the Hawaiian Islands, coupled with climate change, are the greatest threat facing Hawaiian forest birds today. 

"As the climate warms and more mosquitoes move into the once malaria-free regions of the mountains, healthy birds are running out of places to escape the cycle of infection," said Eben Paxton, a research ecologist with the USGS Pacific Island Ecosystems Research Center (PIERC) in Hawai'i. Now, PIERC biologists are working with a range of partners, including other Interior Department bureaus and the Birds Not Mosquitos Coalition, to intercept the disease cycle using a novel conservation tool.

Scientists have published a series of recommendations to enable communities and managers to minimise the impact of lionfish in the Mediterranean Sea. The invasive species was first noticed off the coast of the Lebanon in 2012, with sightings since recorded as far west as Sicily, and north into the Adriatic Sea off Croatia. More entered in 2015 due to the enlargement and deepening of the Suez Canal, with their spread unimpeded due to a lack of common predators. Researchers in the UK and Cyprus have said increasing lionfish densities – combined with the species' generalist diet and consumption of ecologically and socio-economically important fish – has the potential to result in further disruption of an already stressed marine environment. They have now published a Guide to Lionfish Management in the Mediterranean [PDF, 8.0 MB], which features a series of recommendations through which they hope lionfish populations can be managed.

A map identifying the areas suitable for establishment of the spotted lanternfly (SLF) in the United States and other countries has been published in the Journal of Economic Entomology by Agricultural Research Service scientists. The SLF, originally from China, has spread to Korea and Japan, and has been found most recently in the United States in Pennsylvania, New Jersey, Virginia and Delaware. These insects are pests of many agricultural crops including almonds, apples, blueberries, cherries, peaches, grapes and hops as well as hardwoods such as oak, walnut and poplar, among others. USDA and State partners have been working to contain SLF populations since 2014. There is the potential for far reaching economic damage if the SLF becomes widely established in the United States.

New research from The University of Western Australia has shed light on why some invasive plants make a better comeback after a fire, outstripping native species in the race for resources.

The Great Lakes Fishery Commission today reported that populations of the invasive, parasitic sea lamprey remain at near-historic lows, below targets, in Lakes Michigan and Ontario, and above target, but holding steady, in Lakes Huron, Superior and Erie. Sea lamprey populations in Lake Huron are close to target levels and have been holding steady for the past five years. Abundances in Lakes Superior and Erie remain above target but have also decreased significantly since the near-record highs observed in 2017. Sea lampreys are the worst of the alien species to invade the Great Lakes. Before control, sea lampreys destroyed many times the human fish catch. Today, sea lamprey control is the foundation of the $7 billion Great Lakes fishery. The Commission and its partners are encouraged by the overall decrease in abundance of sea lampreys throughout the Great Lakes basin during 2019, but caution that environmental conditions, such as a prolonged spring and high precipitation events, contributed to the decrease.

Seed banks can provide insight into a forest’s past and give land managers valuable information to help them plan for the forest’s future. For example, knowing which species may germinate after future fires is valuable, especially when nonnative invasive species in the seed bank could proliferate quickly following disturbances.

In this study, researchers analyzed the species composition of buried seeds and extant vegetation present in areas that have faced differing fire conditions over many years on the Monongahela National Forest in West Virginia.

Spotted lanternfly is a threat to Maryland and the U.S. The Maryland Department of Agriculture issued a quarantine October 28, 2019 in an effort to contain the invasive species in Cecil and Harford counties after the spotted lanternfly was spotted in Cecil’s northeastern corner and along Harford’s northern border. 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.

Injurious wildlife provision of the Lacey Act provides effective tool to halt the introduction and spread of species that have been identified as imminent and serious threats. The U.S. Fish and Wildlife Service took action to help ensure 10 nonnative freshwater fish species and one nonnative freshwater crayfish species do not become established in the United States and damage native wildlife and habitats.

The U.S. Fish and Wildlife Service is announcing a $100,000 challenge to combat white-nose syndrome (WNS), a lethal fungus that has killed millions of bats in North America and pushed some native bat species to the brink of extinction. Funding will be awarded to individuals who identify innovative ways to permanently eradicate, weaken or disarm the disease.

There is no known cure for white-nose syndrome, but scientists worldwide are working together to study the disease and how it can be controlled. Much of this work has been conducted under the umbrella of the U.S. National Response to White-nose Syndrome, a broad, multi-agency effort led by the Service.

The deadline for individuals or teams to enter the challenge was Dec.31, 2019. Winning ideas will be the focus of future collaborations with scientists, designers and engineers to bring solutions to life. Additional information regarding rules and eligibility is available at White-nose Syndrome Challenge.

The U.S. Fish and Wildlife Service announced a proposal to list the tricolored bat as endangered under the Endangered Species Act (ESA). The species faces extinction due primarily to the range-wide impacts of white-nose syndrome, a deadly disease affecting cave-dwelling bats across the continent.

Bats are essential for healthy ecosystems and contribute at least $3 billion annually to the U.S. agriculture economy through pest control and pollination. The growing extinction crisis highlights the importance of the ESA and efforts to conserve species before declines become irreversible.

ITP is pleased to announce the release of seven new screening aids for important Coleoptera and Lepidoptera pests. These were designed specifically to be used when examining traps or through visual inspection as part of surveys conducted by state cooperators for the APHIS PPQ Cooperative Agricultural Pest Survey (CAPS) program. CAPS surveys help officials monitor and gather data about pests on high-risk hosts and commodities, including pests that may have been recently introduced to the United States. The new screening aids are for city longhorn beetle, Agrilus of concern, pinecone and bamboo longhorn beetles, tomato fruit borers, coconut rhinoceros beetles, spruce longhorn beetles, and velvet longhorn beetle. All of ITP's CAPS screening aids can be found on the ITP website and on the CAPS Resource and Collaboration site Screening Aids page.

The spongy moth, (Lymantria dispar), formerly known as the "gypsy moth," continues to spread throughout North America, threatening deciduous trees and impacting humans. This non-native, foliage-feeding insect currently occupies only about one-third of its possible host distribution in the United States. Efforts to reduce its impact and spread represent one of the largest and most successful federal and state agency integrated pest management programs against a forest pest.

This new General Technical Report (GTR), published by the Northern Research Station, synthesizes information about the Slow the Spread Program, its accomplishments, and provides a framework for future landscape-level integrated pest management.
