  • Balancing Act: A Policy Success Story in the Great Lakes

    • Feb 23, 2024
    • Michigan State University. Michigan Sea Grant.

    • The Great Lakes remain one of the most heavily invaded freshwater systems in the world. Ballast water from cargo ships crossing the ocean inadvertently brought in many aquatic invasive species (AIS), accounting for the introduction of 40% of all nonindigenous aquatic species in the Great Lakes. However, collaborative efforts have led to pioneering research and policy changes that have reduced this threat.

  • Minnesota DNR Classifies 13 Invasive Plants, Animals as Prohibited

    • Feb 20, 2024
    • Minnesota Department of Natural Resources.

    • The Minnesota Department of Natural Resources has classified 13 high-risk invasive aquatic plants, fish and invertebrates as prohibited invasive species. The DNR classifies invasive species as prohibited to prevent their introduction and spread in Minnesota and to protect the state’s environment, economy, natural resources and outdoor recreation. It is unlawful to possess, import, purchase, transport or introduce prohibited invasive species, except under a DNR-issued permit for disposal, decontamination, control, research or education.

      The prohibition on 12 of the 13 species is effective immediately, with publication of the new listings in today’s State Register. Jumping worms will be prohibited invasive species effective July 1, 2024, to provide additional time for outreach to businesses and others who may be impacted by the rule change. A complete list is available on the DNR invasive species laws website.

  • USGS to Deploy Bait Stations for Invasive Grass Carp in Upper Mississippi River

    • Feb 15, 2024
    • DOI. United States Geological Survey.

    • From March to May 2024, scientists from the USGS will install baiting platforms for invasive grass carp and equipment for monitoring fish movement in pool 19 of the Upper Mississippi River. Pool 19 contains 30,466 acres of aquatic habitat, extending 46.3 miles from Lock & Dam 19 located near Keokuk, Iowa upstream to Lock & Dam 18 located near Burlington, Iowa.

      Project completion is expected by December 2024, with results being publicly available in 2025. This project is supported through the U.S. Geological Survey Ecosystems Mission Area, Biological Threats Research Program, and the Great Lakes Restoration Initiative.

  • Vector-Borne Diseases (VBD) National Strategy to Protect People

    • Feb 2024
    • DHHS. CDC. Division of Vector-Borne Diseases (DVBD).

    • The U.S. Department of Health and Human Services released the National Public Health Strategy to Prevent and Control Vector-Borne Diseases in People (VBD National Strategy). As directed by the 2019 Kay Hagan Tick Act—named after the U.S. Senator who died due to complications from a tickborne illness—HHS led a four-year process with civilian agencies and defense departments to deliver this strategy. Co-led by the HHS Office of the Assistant Secretary for Health and the Centers for Disease Control and Prevention, the strategy identifies and describes federal priorities to detect, prevent, respond to, and control diseases and conditions caused by vectors in the United States. This VBD National Strategy represents the largest formal federal coordination effort focused on vector-borne disease prevention and control with contributions by over 50 representatives across 17 federal agencies.

  • Balancing Act: Unveiling Public Perspectives on Taming Invasive Aquatic Plants

    • 2023
    • Agricultural & Applied Economics Association. Choices Magazine.

    • Aquatic invasive species threaten U.S. freshwater bodies throughout the country. One of the most prevalent and prevailing of these is hydrilla (Hydrilla verticillate), which spans from Florida all the way up to Maine, and as far west as California. The state of Florida alone spent $125 million from 2008 – 2015 to manage aquatic invasive species, $66 million of which went toward managing hydrilla. The Florida Fish and Wildlife Conservation Commission (FWC) is estimated to spend $15 million annually on managing hydrilla. This submerged weed is primarily managed through cost effective, safe aquatic herbicides and more costly mechanical harvesting. Due to the prevalence of hydrilla, understanding stakeholder perceptions regarding its management is critical to its successful control. 

      This infographic displays Florida’s stakeholder perceptions around aquatic herbicide and mechanical harvesting usage, which can be utilized as a model for other states as well. Data analysis of 3,000 survey responses concluded that a majority of stakeholders are concerned about both the use of aquatic herbicides and mechanical harvesting.

  • Federal Agencies Commit to Continue a Crucial Collaborative Bat Monitoring Program

    • Feb 9, 2024
    • DOI. United States Geological Survey.

    • 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

      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.

  • High-Impact Invasive Plants Expanding into Mid-Atlantic States

    • Jan 19, 2024
    • University of Massachusetts Amherst. Northeast Climate Adaptation Science Center.

    • With climate change, many invasive plants are projected to shift their ranges, creating hotspots of future invasions across the U.S. Knowing the identities of new invasive plants headed to a nearby state creates an opportunity for proactive prevention and management. Unfortunately, monitoring for and managing all range-shifting invasive plants is untenable. To help prioritize range-shifting species, Northeast Climate Adaptation Science Center researchers performed impact assessments on 104 plants projected to expand into one or more mid-Atlantic states by 2040 with climate change. Their study was recently published (Oct 6, 2023) in Invasive Plant Science and Management "High-impact invasive plants expanding into mid-Atlantic states: identifying priority range-shifting species for monitoring in light of climate change."
