Amendments to an international treaty aimed at preventing the spread of potentially invasive species in ships' ballast water entered into force on 13 October 2019. The International Convention for the Control and Management of Ships' Ballast Water and Sediments, 2004 (the BWM Convention) was adopted by the International Maritime Organization (IMO), a specialized agency of the United Nations, to address this problem. The BWM Convention entered into force in 2017. The amendments formalise an implementation schedule to ensure ships manage their ballast water to meet a specified standard ("D-2 standard") aimed at ensuring that viable organisms are not released into new sea areas, and make mandatory the Code for Approval of Ballast Water Management Systems, which sets out how ballast water management systems used to achieve the D-2 standard have to be assessed and approved. This will help ensure that aquatic organisms and pathogens are removed or rendered harmless before the ballast water is released into a new location – and avoid the spread of invasive species as well as potentially harmful pathogens.
The AIM campaign that focuses on providing information and best practices to manage The Organisms in Trade (OIT) pathway. The OIT pathway is one of the main avenues by which non-native aquatic species become established in waterways. Many of the aquatic plants and animals available in the marketplace can negatively impact ecosystems, economies, and public health when introduced to new freshwater habitats. AIM was developed by a collaboration of researchers and outreach specialists led by Illinois-Indiana Sea Grant and the Illinois Natural History Survey.
Understanding how wild birds facilitate the maintenance, reassortment, and dispersal of influenza A viruses (IAV) is key to forecasting global disease spread. The current highly pathogenic avian influenza outbreak in North America highlights the question of how viruses are transported between continents. Recent NWHC research sheds light on this question and the potential role Iceland may play.
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.

The 2018 Vessel Incidental Discharge Act (VIDA) requires an annual report on the effectiveness of national ballast water management (BWM) requirements. This report provides analyses of (1) the patterns of ballast water (BW) delivery and management; (2) Coast Guard’s compliance and enforcement actions regarding BWM regulations; and (3) patterns of biological invasions by marine and estuarine aquatic nuisance species (ANS). It covers the two-year period from January 2020 through December 2021 to demonstrate the effectiveness of the Coast Guard’s statutorily mandated BWM regulatory program and validates that enforcement efforts continue to increase BWM and reduce the risk of introducing ANS into U.S. waters.

The aim of this report was to identify the resources, strategies, and policies necessary to create, maintain, and make accessible one or more commodity/invasive species databases that EPA and other relevant agencies can apply to trade policy decision-making in a timely and scientifically-based manner.
Discover the importance of using local firewood to avoid spreading harmful forest pests. The Don’t Move Firewood campaign is an outreach partnership managed by The Nature Conservancy. The overarching goal of the campaign is to protect trees and forests all across North America from invasive insects and diseases that can travel in or on contaminated firewood. The central tenet of the Don’t Move Firewood campaign is that everyone has a role to play in slowing the spread of invasive tree killing insects and diseases, through making better informed firewood choices. For more information on how you can do your part, please see Frequently Asked Questions.
Firewood Month Toolkit -- During Firewood Month (October), reduce firewood movement to slow the spread of forest pests and diseases via the firewood pathway.
Emerald Ash Borer Awareness Weed Toolkit -- During Emerald Ash Borer Awareness Week (May 19-26, 2024) everyone is encouraged to take a few minutes to learn about the signs and symptoms of emerald ash borer infestation on ash trees so that the infestations can be better managed by local tree professionals and foresters.
On Monday April 8, 2024, a total eclipse of the sun will be visible in a roughly 115 mile wide swath (called the path of totality) crossing North America as it passes over Mexico, the U.S., and Canada. Millions of travelers are expected to camp out over the weekend so they can be in the best viewing area on Monday to see the amazing spectacle of a complete solar eclipse. The Nature Conservancy is asking everyone that plans to use firewood for the solar eclipse celebration weekend to buy local firewood near their destination, bring packaged certified heat-treated firewood, or gather their firewood responsibly on site if permitted by the campground or landowner.
In 2010, Oregon, Washington, and Idaho launched a tri-state outreach campaign to inform the public about the dangers of moving firewood to Pacific Northwest forests. The campaign, funded by the United States Department of Agriculture, closely followed the messaging of the national Don't Move Firewood campaign, which recommends buy firewood that was cut locally, preferably within the county or region of where it will be burned. The tri-state outreach campaign, Buy It Where You Burn It, encouraged good campfire practices with branded posters, billboards, and playing cards located at rest stops and state parks.
