New York Invasive Species Awareness Week.

The mission of the New York Invasive Species Awareness Week (ISAW) is to promote knowledge and understanding of invasive species and the harm they can cause by engaging citizens in a wide range of activities across the state, and empowering them to take action to help stop the spread. This annual education campaign is comprised of various outreach initiatives and events led by partner organizations statewide. Activities include interpretive hikes, invasive plant removal, and restoration projects, displays, webinars, radio and television programming, and more.

The Tennessee Department of Agriculture (TDA) is advising forest landowners to monitor their sassafras trees after detecting new cases of laurel wilt disease in Robertson and Hamblen Counties. In the last quarter of 2019, the disease was detected in trees in Montgomery, Cheatham, Dickson and Williamson Counties. "These new detections of this invasive disease show a significant geographic jump across the state," State Forester David Arnold said. "This is yet another unfortunate example of an invasive pest impacting our forests. Landowners should take caution to prevent the spread of this disease if detected on their property."

Laurel wilt is a fungal disease caused by an invasive pathogen, Raffaelea lauricola, which can affect a range of plants, including sassafras and spicebush in Tennessee. Choked of water, trees wilt and die within a few weeks or months. Currently, no treatment has been developed that can cure laurel wilt disease or protect trees from infection. The best way to prevent the spread of laurel wilt is to avoid movement of firewood or other untreated timber. Tennesseans are urged to monitor their sassafras trees for browning of leaves, leaf loss, and staining in the inner bark. If you suspect your trees might have laurel wilt disease, contact Forest Health Program Specialist Sam Gildiner at 615-837-5439 or sam.gildiner@tn.gov. TDA Division of Forestry staff will assist in identifying the disease and recommending management actions, if appropriate.

Three Tennessee counties have been quarantined for Emerald Ash Borer (EAB) after detection of the forest-devastating insect, bringing the total number of Tennessee counties under a state and federal EAB quarantine to 62. Cheatham, Giles, and Maury counties have been added to the list of areas restricted for the movement of firewood, ash nursery stock, ash timber, and other material that can spread EAB. The tree-killing beetle was recently found in these three counties through the United States Department of Agriculture’s EAB detection program.
