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 U.S. Geological Survey has released a comprehensive synthesis of Burmese python science, showcasing results from decades of USGS-funded research on python biology and potential control tools. The giant constrictor now represents one of the most challenging invasive species management issues worldwide.

Classical biological control, which reunites invasive insects or plants that have spread in new, invaded areas with their natural enemies, is the only means of reducing permanently and over large areas the harm such invaders cause. Short of eradication, which is rarely practical once an invader has spread widely, this method is the only solution that does not depend on endless control activities and their associated costs. The purpose of this book is to highlight the value that programs of classical insect and weed control have provided to the United States over roughly the last 40 years (1985–2022).

Ailanthus altissima (tree-of-heaven) is a rapidly growing invasive tree species introduced to the United States nearly 200 years ago. Today, this species is a common invader in many forests across the nation. Scientists with the Northern Research Station have identified a unique biological control measure for managing Ailanthus—Verticillium nonalfalfae, a native soil-borne fungus. Check out this latest issue of Rooted in Research that explores how Verticillium can reduce Ailanthus populations.
Callery pear (Pyrus calleryana) can be found across most of the eastern U.S. and in a few western states as well. The nonnative tree was brought to the U.S. in 1917 by a USDA employee searching for a blight-resistant species that could be bred with European pear to increase fruit production.
The most common Callery pear cultivar is the Bradford pear. In the last two decades, this near-ubiquitous landscaping tree has been identified as a serious invasive pest. A new publication examines herbicide treatments to control the spread of Callery pear. Lead author J.T. Vogt is a research scientist with the USDA Forest Service.
Researchers have been working on a solution to fight citrus greening disease and may have found one in the unique antibodies found in camels, llamas, and alpacas.
USDA APHIS' Plant Protection and Quarantine (PPQ) provides national leadership and coordination in crop biosecurity and emergency management. As the lead Federal agency for plant health emergencies, PPQ works cooperatively with national and international plant protection organizations; Federal, State, tribal, and local agencies; universities; industries; and private entities in developing and implementing science-based framework designed to provide optimum protection against invasive pests and diseases.

This video will help maintenance crews recognize and control noxious weeds along roadsides. Road crews that maintain any type road, from interstate highways to aggregate roads, are the frontline in preventing the spread of invasive plants.
As APHIS is an animal and plant health agency, data visualization tools are critical to their work. APHIS surveys for pests and diseases, set quarantine boundaries, and track wildlife hazards, among other tasks that require spatial awareness and dynamic engagement. This section provides plant and animal health publicly available applications (interactive story maps) which support the APHIS mission.
The Chesapeake Bay Nutria Eradication Project (CBNEP) announced at an event at Blackwater National Wildlife Refuge today that Maryland is now free of the exotic, invasive nutria. The U.S. Fish and Wildlife Service (USFWS), U.S. Department of Agriculture’s Wildlife Services (WS), and Maryland Department of Natural Resources (DNR) have worked more than 20 years to make this difficult task -- never accomplished before on this scale -- a success.
