Tennessee Department of Agriculture.

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.

These best management practices for water accesses have been developed by the Minnesota Department of Natural Resources in an effort to reduce the spread of aquatic invasive species (AIS). By following these guidelines, providers of public and private boat access facilities can create visible and functional designated areas where boaters can clean and drain boating equipment and conduct other AIS prevention activities.

An affirmation card reminds boaters and nonresident anglers of Minnesota’s aquatic invasive species laws. Watercraft owners and nonresident anglers must read and sign the affirmation during their regular license renewal, then keep it in their possession with their license. The affirmation, enacted by the Minnesota Legislature, is another positive step in the state’s proactive efforts to keep 95% of Minnesota lakes off the infested waters list.

Outreach materials are provided to help organizations and individuals promote aquatic invasive species (AIS) prevention activities in their communities. Minnesota DNR's Invasive Species Program provides printed materials and design files, as well as providing review of AIS materials created by other organizations.

Native to Asia, the Emerald Ash Borer is an exotic beetle that was unknown in North America until June 2002 when it was discovered as the cause for the decline of many ash trees in southeast Michigan and neighboring Windsor, Ontario, Canada. It has since been found in several states from the east coast spanning across the midwest and in June 2006, we discovered that it had taken up residence in Illinois.
