Tennessee’s forest health management program seeks to minimize resource losses from forest insects, disease, vertebrate pests, or other sources impacting growth such as flooding and air pollution. It monitors and evaluates pest occurrences, promotes healthy forests through education and technical assistance and implements integrated pest management strategies on state forests, nurseries, and orchards.

Hemlock die-off having major ecological impact in Smokies
(July 11, 2016) - Forests throughout the Great Smoky Mountains National Park are undergoing a major ecological shift due to the widespread deaths of hemlock trees caused by an unwelcome insect. Forestry experts tell the Knoxville News Sentinel that hemlocks that for years were in a state of decline are now dead and toppling to the ground, creating a void that could affect everything from stream temperatures to forest composition. The die-off has been linked to the hemlock woolly adelgid, an invasive species that was discovered in the park in 2002.

Tennessee State Parks Asks Public Not to Move Firewood
(May 18, 2016) - Tennessee State Parks, in partnership with the Department of Agriculture Division of Forestry and The Nature Conservancy, is advising the public of a new policy regarding bringing firewood into parks. Beginning June 1, Tennessee State Parks will advise visitors to use certified heat-treated wood. The new policy aims to prevent or slow the introduction of exotic insects or diseases into parks that could otherwise threaten the health of our trees and forests. Visitors who want to have a campfire can bring certified heat-treated firewood into a park or use dead and down wood from an area adjacent to the fire. Manufactured fire logs will also be acceptable. Many parks, in conjunction with approved vendors, will have certified heat-treated firewood available for sale. “Transportation of firewood is a primary pathway for the introduction of harmful pests and pathogens to Tennessee’s forests and woodlands,” said Jere Jeter, Tennessee State Forester with the Department of Agriculture. “We are pleased that State Parks has taken this important step to reduce the risks of new infestations and assist us with the protection of Tennessee’s trees.”

Asian beetle invasion threatens Chattanooga area ash trees with destruction (Times Free Press)
(April 4, 2016) - Jimmy Voyles has a $5,000 problem everyone with an ash tree in their yard needs to know about — because it soon will be their problem, too. On April Fool’s Day afternoon, several blocks from Amnicola Highway in East Chattanooga, the trees in Voyles’ yard were all starting to bud bright green — except for four large ash trees. Broken branches lay on the ground beneath them, and on one, the bark had peeled away to reveal a strange pattern resembling a New York subway system map, with a network of tunnels making S-curves down the side of the tree.

Bradford pear trees create landscape issues for East Tennessee (WBIR)
(April 4, 2016) Bradford pear trees are one of the first trees to bloom in the spring in East Tennessee, but tree experts are warning that they are causing problems for the area. Kasey Krouse, the urban forester for the City of Knoxville, said he has been trying to educate the public on the potential ramifications this tree can cause for the government... "It was a hot tree to plant at the point in time, and it wasn't until 15-20 years later, just in the recent history, that we started seeing the real problems associated with the pear tree," Krouse said... Krouse now fears that the trees, if left uncontrolled, will push out other native vegetation.

(Oct. 23, 2015) - Private landowners near Stinging Forks Falls State Natural Area in Rhea County are joining forces with the Tennessee Hemlock Conservation Partnership to show area landowners how to save their majestic, but threatened hemlock trees. A free workshop to be held Saturday, Nov. 14, will help private landowners learn about the threat of hemlock woolly adelgid (HWA) and gain skills needed to safely treat and preserve their own hemlocks. “The hemlock woolly adelgid has the potential to kill our hemlocks, changing the natural landscape my family and I have known for the last 20 years,” said Chris Anderson, who manages 232 acres on his family’s certified forestry tree farm, CRC Stewardship Ridge, between Stinging Fork Falls and Piney Falls state natural areas and bordering the Cumberland Trail.
