Minnesota Department of Natural Resources.

The Minnesota Department of Natural Resources is conducting an immediate response to the capture of 51 invasive carp on the Mississippi River. The invasive carp were caught by two commercial fishing operators near La Crosse and Trempealeau, Wisconsin, during routine spring netting last weekend. In response to this discovery, the DNR is working with the U.S. Fish and Wildlife Service, the U.S. Geological Survey, the Wisconsin DNR and commercial fishing operators to conduct large-scale netting, studies of the captured carp and increased monitoring. "The location where these fish were caught is commonly netted because of concentrations of commercially valuable fish," said DNR invasive carp field lead Ben Larson. "This is the largest congregation of invasive carp we've seen this far upstream." Invasive carp have been progressing upstream since escaping into the Mississippi River in Arkansas in the 1970s. These large fish compete with native species and pose a threat to rivers and lakes.

Invasive carp captures must be reported to the DNR immediately. Call 651-587-2781 or email invasivecarp.dnr@state.mn.us. Take a photo and transport the carp to the nearest DNR fisheries office or make arrangements for it to be picked up by a DNR official. More information about invasive carp is available on the Minnesota DNR website.

New Prevention Topics

USDA. NAL. National Invasive Species Information Center.

Watercraft Inspection and Decontamination Programs - Many Western states instituted watercraft inspection and decontamination programs after the discovery of invasive mussels in Lake Mead in 2007. This section provides resources on mandated watercraft inspection and decontamination programs, as well as some non-mandated but state-funded watercraft inspection efforts.

Aquatic Invasive Species Decals - Some U.S. states require that boaters purchase an aquatic invasive species decal (sometimes called a stamp, sticker, or permit) before operating watercraft in that state. Many of these regulations were instituted as a response to the spread of zebra and quagga mussels into the Western U.S. Fees from the purchase of these decals are typically used to fund local aquatic invasive species outreach and prevention activities.

Great Lakes Commission.
Aquatic invasive species inflict millions of dollars of ecological and economic damage to the Great Lakes, with impacts on coastal industries, water quality, native fish and wildlife and human health. Recently, Blue Accounting, in partnership with state and federal agencies, launched a new suite of web-based resources and tools to support early detection of aquatic invasive species in the Great Lakes. The earlier new aquatic invasive species are detected, the easier and less expensive it is to avoid potentially devastating consequences of a large invasion. The new tools released by the Blue Accounting initiative help target efforts to focus on high-risk species and locations across the 11,000 miles of shoreline and 94,000 miles of surface area that make up the Great Lakes basin.

Pennsylvania Department of Agriculture.

Pennsylvania Agriculture Secretary Russell Redding today announced that twelve counties have been added to Pennsylvania's Spotted Lanternfly quarantine zone ahead of the 2020 spring hatch. With this addition, the quarantine (PDF | 506 KB) for this invasive pest is now at 26 counties. The new dozen counties are not completely infested, but rather have a few municipalities with a known infestation (PDF | 803 KB) which led to a quarantine being placed on the entire county out of an abundance of caution. Allegheny, Beaver, Blair, Columbia, Cumberland, Huntingdon, Juniata, Luzerne, Mifflin, Northumberland, Perry, and York have been added to the quarantine for 2020.

Pennsylvania Department of Conservation and Natural Resources.
Pennsylvania Department of Conservation and Natural Resources Secretary Cindy Adams Dunn announced that the department is launching an effort at nine state parks this summer to help prevent the spread of aquatic invasive species, and get boaters involved in invasive species detection. "Boats, motors, and trailers have ideal hiding spots where species may attach, and be transported to new locations," Dunn said. "Boaters must be involved in helping us protect state park waters from invaders, to benefit our environment and avoid very costly measures to treat lakes once these non-native species take hold." Starting this week, DCNR staff will be doing voluntary boat and trailer checks at boat launches on park lakes, handing out informational brochures and demonstrating how to do an inspection.

Great Lakes Fishery Commission.

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.

PennsylvaniSea Grant College Program.

Aquatic invasive species (AIS) pose a significant threat to Pennsylvania’s economy, freshwater resources, and native aquatic species. Pennsylvania Sea Grant announces 'there’s an app for that' with the launch of "PA AIS," a new, easy-to-use smart phone application. The "PA AIS" app is now available in the Apple App Store, with an Android version anticipated. The "PA AIS" app can be used in airplane mode or in areas outside of coverage, making it ideal for use in the field. Users can identify AIS and submit a report to the state AIS coordinator, including the location, severity, and photos of the suspected infestation. Illustrations help users learn more about each species to ensure accurate identification in the field. Prevention tips help educate freshwater enthusiasts such as anglers and boaters about the steps they can take to properly clean gear and ensure that AIS are not transported from one water body to another.

University of Massachusetts Amherst.

The U.S. Department of the Interior has renewed its support for the Northeast Climate Adaptation Science Center (NE CASC) at the University of Massachusetts Amherst with a five-year, $4.5 million commitment as the host campus for its six-member consortium of universities, says center co-director professor Richard Palmer. Scientists affiliated with the center provide federal, state and other agencies with region-specific results of targeted research on the effects of climate change on ecosystems, wildlife, water and other resources. The new agreement continues Interior’s original seven-year, $11 million grant to the NE CASC at UMass Amherst that began in 2011. One of the web-based tools created by the NE CASC is the Regional Invasive Species and Climate Change (RISCC) Management project, which helps invasive species managers through working groups, information-sharing and targeted research.

USDA. National Institute of Food and Agriculture; University of New Hampshire.
Researchers at the University of New Hampshire have found a dramatic decline of 14 wild bee species that are, among other things, important across the Northeast for the pollination of major local crops like apples, blueberries and cranberries.

“We know that wild bees are greatly at risk and not doing well worldwide,” said Sandra Rehan, assistant professor of biological sciences. “This status assessment of wild bees shines a light on the exact species in decline, beside the well-documented bumble bees. Because these species are major players in crop pollination, it raises concerns about compromising the production of key crops and the food supply in general.”

USDA. Animal and Plant Health Inspection Service.

The U.S. Department of Agriculture's Animal and Plant Health Inspection Service (APHIS) is working with the Texas Department of Agriculture (TDA) to combat the Mexican fruit fly (Anastrepha ludens) in Cameron and Willacy Counties in Texas. Following the detection of this pest in Cameron and Willacy Counties in January 2020, APHIS put quarantines in place to contain this fruit fly and is conducting surveys to find and treat infestations. Mexican fruit fly is one of the world's most destructive invasive pests, attacking more than 40 different kinds of fruits and vegetables. This invasive fruit fly does not harm humans or animals but it poses a serious threat to the Texas citrus industry.

APHIS needs the public's help to limit this invasive fruit fly's spread. We are asking residents living or working within Mexican fruit fly quarantine areas to cooperate with survey teams and give them access to your property. Surveyors will have official credentials identifying them as U.S. Department of Agriculture or TDA employees. With the residents' permission, they will inspect fruit trees on residential properties in quarantine zones and hang traps. If APHIS or TDA detect Mexican fruit flies, they will work with residents and business owners to eradicate the pest from infested properties.

If you live in the Lower Rio Grande Valley and think you might have Mexican fruit flies on your property, please call APHIS at 956-421-4041. With your help, we can protect local agriculture and stop the spread of this destructive pest.

Texas Parks and Wildlife Department.

For the first time, Texas Parks and Wildlife Department (TPWD) biologists have confirmed the disease white-nose syndrome (WNS) in a Texas bat. Up until this point, while the fungus that causes the disease was previously detected in Texas in 2017, there were no signs of the disease it can cause. WNS has killed millions of hibernating bats in the eastern parts of the United States, raising national concern. WNS is a fungal disease only known to occur in bats and is not a risk to people. However, bats are wild animals and should not be handled by untrained individuals. The public is encouraged to report dead or sick bats to TPWD at nathan.fuller@tpwd.texas.gov for possible testing.
