  • A New Decision Support Tool for Preventing the Spread of Aquatic Invasive Species

    • Mar 2024
    • USDA. FS. Northern Research Station. Rooted in Research.

    • A New Tool for Helping Managers Make Decisions about Inspections -- to help inform decision making, researchers developed AIS Explorer: Prioritization for Watercraft Inspections, a web-based decision-making support tool for optimizing watercraft inspection efficiency. The online dashboard incorporates data about which lakes are infested and how boats move among lakes in Minnesota (gathered from surveys at watercraft inspection stations), and it updates automatically as new entries are added to the Minnesota Department of Natural Resources Infested Water List.

      This decision support tool can help counties position their limited inspection resources strategically to protect the greatest number of waterbodies and safeguard the state’s ecological and economic assets.

  • Army Corps of Engineers: Better Data and Planning Needed to Combat Aquatic Invasive Species

    • Nov 6, 2023
    • United States Government Accountability Office.

    • Quagga and zebra mussels have spread rapidly across the country since they were first discovered in the late 1980s and, according to U.S. Army Corps of Engineers officials, have spread to every major river basin in the U.S. except the Columbia River Basin in the northwest. The mussels typically are spread by recreational watercraft such as boats, canoes, and Jet Skis that have been in infested waters. Once established in a water body, the mussel species are extremely difficult to eradicate because they have no natural predators in the U.S. and rapidly reproduce.

      GAO was asked to examine efforts the Corps has undertaken to prevent the spread of aquatic invasive species into the Columbia River Basin by recreational watercrafts. This report [PDF, 3.24 MB] provides information on the Corps' Watercraft Inspection and Decontamination Program and its role in helping to prevent the introduction or spread of quagga and zebra mussels—the aquatic invasive species of greatest concern to the Corps—as well as program challenges and opportunities for improvement.

  • Decontaminating Wildland Fire Equipment to Prevent the Spread of Aquatic Invasive Species (AIS): How to Guide [PDF, 1.7 MB]

    • Jun 2022
    • National Wildfire Coordinating Group.

    • This updated protocol is based on the National Wildfire Coordinating Group (NWCG)’s 2017 “Guide to Preventing Aquatic Invasive Species Transport by Wildland Fire Operations” (PMS 444). The intent of this NRCG guide is to provide a more prescriptive protocol intended for a fire management audience, and to increase compliance and consistency of best management practices related to preventing AIS. The protocol applies to both ground operations and aviation and is mandatory in the Northern Rockies region. This protocol is demonstrated via a “How to Guide,” which includes detailed instructions for ordering, set up, and assembly of AIS decontamination stations; options for products/equipment based on site specific conditions; and best management practices for drafting water, which can prevent the risk of most AIS being transported or spread via wildland fire equipment. Fire management agencies in the west are taking the threat of AIS seriously and have committed to decreasing the possible risk of introduction and spread by fire management personnel.

  • New Research Provides Guidance for Effective Public Messaging About Invasive Species Prevention

    • Aug 20, 2021
    • University of Wisconsin Sea Grant.

    • You could say that preventing the spread of aquatic invasive species (AIS) is a team sport. While it takes the professional efforts of natural resource managers, AIS specialists and others in the environmental field, it also takes the cooperation of the public. Yet for community members to take necessary actions, they must first be aware of the negative impacts AIS can have and how to stop their spread. Communicating with them about AIS in an effective way is vital.

      New research from Wisconsin Sea Grant Aquatic Invasive Species Outreach Specialist Tim Campbell, University of Wisconsin-Madison Associate Professor Bret Shaw and consultant Barry T. Radler sheds new light on such communication. The researchers analyzed which communication strategies are most effective and which may pose unintended problems. The team's findings were published online Aug. 14 in the journal Environmental Management (“Testing Emphasis Message Frames and Metaphors on Social Media to Engage Boaters to Learn about Preventing the Spread of Zebra Mussels”).

  • Protecting Agriculture on the Internet – One Click, One Post, One Sale at a Time

    • Apr 24, 2018
    • USDA. Blog.

    • A big way invasive pests can move from one location to another is through unregulated internet sales. We are seeing more and more of these sales, and it’s a real concern. Why? With normal commercial or retail sales, we can use techniques like quarantines and fumigation to make sure that purchased items are pest-free or don’t enter pest-free areas. But many times, sales on the internet do not follow these techniques, opening up the chance for invasive pests to move freely to new areas. APHIS' Smuggling, Interdiction and Trade Compliance Office looks for these types of sale offers online and stops them.

  • Commercial Boat Haulers - Call Before You Haul

    • Pacific States Marine Fisheries Commission. Western Aquatic Invasive Species Resource Center.

    • To prevent the spread of aquatic invasive species, the Pacific States Marine Fisheries Commission, U.S. Fish and Wildlife Service, Western Regional Panel on Aquatic Nuisance Species, and others are making information available to boat haulers, auctioneers, marinas, manufacturers, and brokers to make it easy to comply with state, provincial and federal laws, prevent costly delays in transporting or selling boats, and help reduce the spread of aquatic invasive species.

      In December 2021, the Pacific States Marine Fisheries Commission (PSMFC) initiated a program to prevent delays during the transport of watercraft destined for the states of Washington, Oregon, Idaho, and Montana. The program, Call Before You Haul, provides a toll-free number (1-844-311-4873) boat transporters can call prior to transporting watercraft from outside the Pacific Northwest to one of the aforementioned states. The program was piloted in 10 states.

      The Call Before You Haul 1.0 program was initiated in late 2022 prevent the introduction and establishment of quagga and zebra mussels in the Columbia River Basin states and prevent the movement of aquatic invasive species via trailered watercraft. Call Before You Haul 1.0 consisted of creating a 24-7 toll-free number for boat transporters and working directly with state agencies that permit interstate oversize/overweight loads, including watercraft, to raise boat transporter awareness about trailered watercraft as a vector for aquatic invasive species. There remains a significant number of infested watercraft coming from the Great Lakes regions of the United States and Canada to western states.

      Call Before You Haul 2.0 expanding in February 2024, is an effort to work collaboratively with Great Lakes region entities to reduce interstate transport of aquatic invasive species — for the benefit of all states and provinces.

      The EPA's National Pollutant Discharge Elimination System (NPDES) Vessel General Permit (VGP) and Small Vessel General Permit (sVGP) regulate discharges incidental to the normal operation of commercial vessels, including ballast water and hull fouling, which are both pathways for introductions of aquatic nuisance species. The EPA and the Department of Defense are jointly developing the Uniform National Discharge Standards for vessels of the Armed Forces which will also regulate ballast water and hull fouling to help control the introduction of aquatic nuisance species.

      Note: On December 4, 2018, President Trump signed into law the Frank LoBiondo Coast Guard Authorization Act of 2018, which includes as Title IX the Vessel Incident Discharge Act of 2018 (“VIDA”). The new regulations will replace the EPA’s 2013 Vessel General Permit (“VGP”). EPA first issued the Vessel General Permit (VGP) in 2008 and subsequently reissued it in 2013.
