The Minnesota Department of Natural Resources has been working to slow the spread of invasive carp since the early 2000s. The Invasive Carp Action Plan was revised in 2024. The key purpose of the Action Plan is to slow the spread of invasive carp, minimize their impact, and reduce the likelihood of invasive carp reproducing in Minnesota waters.

The TWRA needs your help in collecting invasive carp. If you catch an invasive carp anywhere in Tennessee other than the Mississippi River OR If you catch any Invasive carp in East Tennessee or other water where invasive carp are not known to be established, the agency is asking that you put it on ice or freeze it and contact them immediately.

If you are unable to keep the fish, the TWRA asks you to submit photos of the fish and send the image to us. You can contact the nearest TWRA office by phone here, or by email at ans.twra@tn.gov.

The Invasive Carp Regional Coordinating Committee (ICRCC) announced the release of its 2022 Invasive Carp Action Plan, a comprehensive portfolio of 60 projects focused on Great Lakes protection. The Action Plan serves as a foundation for the work of the ICRCC partnership — a collaboration of 28 U.S. and Canadian federal, state, provincial, tribal, regional, and local agencies.

The Invasive Carp Regional Coordinating Committee (ICRCC) is pleased to announce the release of its 2023 Invasive Carp Action Plan, a comprehensive portfolio of more than 50 projects focused on Great Lakes protection. The action plan serves as a foundation for the work of the Invasive Carp Regional Coordinating Committee partnership, a collaboration of 26 U.S. and Canadian federal, state, provincial, tribal, regional and local agencies.

USGS scientists, in collaboration with partners, are conducting risk assessments and life history research to enhance the ability of agencies to manage Invasive carp to minimize their influence and spread.

Native freshwater mussels grew more slowly when invasive Asian clams (Corbicula fluminea) were abundant. The study was led by Wendell Haag, a USDA Forest Service research fisheries biologist. The study, "Abundance of an invasive bivalve, Corbicula fluminea, is negatively related to growth of freshwater mussels in the wild" was published in the journal Freshwater Biology. Mussels live out of sight – buried in the river bottom, eating algae and other small particles of organic material. Mussels are filter feeders and key members of aquatic ecosystems. Unfortunately, mussels are disappearing worldwide, and about 70 percent of the 300 mussel species native to the U.S. are in danger of extinction. Addressing mussel declines is difficult because their causes are mostly unknown.

The Arkansas Department of Agriculture is notifying the public that a new invasive grass species, Cogongrass, has been confirmed in Arkansas for the first time. For several years botanists and land managers have been on the lookout for Cogongrass (Imperata cylindrica) in southern Arkansas. This aggressive species, native to Southeast Asia, has spread rapidly across the Deep South over the past few decades. Cogongrass is considered one of the worst invasive species in the world, causing both economic and ecological damages that impact forestry, agriculture, rangeland, and natural ecosystems.

Any sightings of Cogongrass in Arkansas should be reported to Paul Shell, the Department's Plant Inspection and Quarantine Program Manager, at paul.shell@agriculture.arkansas.gov or 501-225-1598.

The Invasive Crayfish Collaborative includes representatives of Great Lakes local, state and federal natural resource agencies, universities, non-governmental organizations (NGOs), and private businesses. These experts and stakeholders are working towards the region’s collective ability to manage and control invasive crayfish.

Imagine walking through a forest, with leaves crunching beneath your feet. Underneath those crunchy leaves is a complex ecological realm. “Soil is teeming with life,” says U.S. Forest Service research ecologist Mac Callaham. “Most people don’t think about it because they don’t see the soil fauna.” Soil fauna includes centipedes, millipedes, springtails, nematodes, insect larvae, and earthworms. “Springtails are very small arthropods,” says SRS ecologist Melanie Taylor. “Earthworms are the giants of soil fauna.” Taylor, Callaham, and lead author Meixiang Gao recently published a study on non-native earthworms and the food web. The study was published in the journal Soil Biology and Biochemistry.

The USDA program to manage Lymantria dispar is a partnership with the Forest Service, APHIS, and state partners, to suppress outbreaks in the generally infested area, eradicate isolated infestations in the uninfested area, and slow the spread along the advancing front.
