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 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.

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.
