Provides comprehensive information on cogongrass in Georgia along with links to other southeastern state efforts on cogongrass. To date, Alabama, Florida, Georgia, Louisiana, Mississippi, South Carolina and Texas have on-going research, education and/or control programs that are supported by university, state and federal agency cooperators.

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.

Georgia Agriculture Commissioner Tyler Harper and the Georgia Department of Agriculture announced the discovery and eradication of three additional Yellow-legged hornets’ nests in the area near Savannah, Ga. In addition to these new eradications, the Department is announcing a new, biweekly newsletter, the Yellow-Legged Ledger, to provide the public with important updates on our efforts to prevent the establishment of this invasive pest.

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.

Scientists from the Connecticut Agricultural Experiment Station (CAES) are reporting that Beech Leaf Disease (BLD) has increased dramatically in both severity and distribution in 2022 compared to 2021. First detected in lower Fairfield County in 2019, BLD is now widespread on American beech (Fagus grandifolia) throughout all eight Connecticut counties, with symptoms most severe in Fairfield, New Haven, Middlesex and New London Counties. Given that BLD is now widely established throughout Connecticut, reports of BLD to CAES and DEEP are no longer requested.

In this issue, we learn about invasive species, their impacts, and what we can do to help stop their spread.

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).

National Cooperative Highway Research Program (NCHRP Synthesis 363). This synthesis reviews federal, state, and regional approaches; prevention, early detection, and rapid responses; identification of aspects of operations and risks; statewide inventories; and information management. In particular, this report synthesizes the state of the practice in developing Integrated (Roadside) Vegetation Management, along with physical, chemical, biological, and cultural control mechanisms.

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.
