Walnut Tree Quarantine in Morgan and Rhea Counties Due to Thousand Cankers Disease
(Nov. 6, 2013) - The Tennessee Department of Agriculture today announced the discovery of a walnut tree killing disease, Thousand Cankers Disease (TCD), in Morgan and Rhea Counties. Walnut Twig Beetles, which transmit the disease causing fungus and the disease itself, have been found in both counties. The counties are now under quarantine. Citizens in these counties cannot move walnut tree products and hardwood firewood outside the quarantined counties.
Tennessee's fragile Cumberland Plateau ecosystem threatened by human interaction, scientists say
(Oct. 8, 2013) - Just west of Chattanooga, Tennessee Department of Environment and Conservation scientists are defending towering hemlock trees in coves along the Cumberland Plateau from a tiny, fuzzy white pest dubbed the hemlock woolly adelgid. The tiny insect, a type of aphid introduced into the East Coast of the United States from Asia in 1951, has been moving slowly westward from parts of the Great Smoky and Appalachian mountains that are closer to the coast. A similar infestation began along the West Coast in 1924.
Emerald Ash Borer Findings Continue to Spread
(Jul. 31, 2013) - Emerald Ash Borer, an invasive insect that destroys ash trees, has been found in Jackson and Scott counties. The identification was made recently and has been confirmed by USDA. Both counties will now be placed under quarantine. Earlier this summer, Hamilton County was also placed under quarantine when EAB was found in trees near a rail hub in Chattanooga. “It appears the newly found infestations of Emerald Ash Borer probably originated through the movement of infested firewood used in camping,” Gray Haun, Tennessee Department of Agriculture’s Plant Certification Administrator said. “Campers need to buy firewood locally where they are camping to avoid introduction of new pests to those areas.”
Emerald Ash Borer found in Hamilton County
(Jul. 1, 2013) - Emerald Ash Borer, an invasive insect that destroys ash trees, has been found in Hamilton County. The identification was made recently and has been confirmed by USDA. The find in Hamilton County is of particular concern because it is not adjacent to the already quarantined areas in East Tennessee. At least a dozen trees adjacent to the rail lines in Chattanooga and an EAB trap located in a park near the rail hub tested positive for the insect.
Bringing back the butternut: Tenn. takes lead in saving tree species
(June 24, 2013) - Researchers believe that 80 percent to 90 percent of the South’s butternuts have been wiped out since the [butternut canker] disease arrived in this country almost 100 years ago. Today, universities and state and federal agencies across the Eastern U.S. are making a coordinated effort to save the butternut. Among the Southeastern states, Tennessee has taken a leading role in the research and development needed to produce disease-resistant, pure butternuts that can be planted in the forest and made available to private landowners.
Tennessee puts up traps to track emerald ash borer beetle
(Jun. 4, 2013) - State and federal agriculture officials are tracking how far the emerald ash borer beetle has advanced by hanging purple triangular traps in trees across Tennessee. The U.S. Department of Agriculture said Friday that the beetle has killed tens of millions of ash trees in the eastern United States and Canada. The species is not native to North America. Tennessee Department of Agriculture spokeswoman Heather Orne told The Commercial Appeal about 1,400 traps are being placed across the state. The goal is to provide a more complete national assessment and to locate new infestations for possible treatment and quarantine. “Trapping is a very important tool for us to know how extensive the infestation is and whether additional control measures are needed to slow it from spreading to other areas,” Tennessee Department of Agriculture plant certification administrator Gray Haun said.
Smokies add 2 new beetles, canopy cages in figth against hemlock adelgid
(May 20, 2013) - At the eastern end of the Great Smoky Mountains National Park, not far from Cosby, Tenn., are three 25-foot-tall hemlock trees enveloped in nylon that appear out of nowhere like circus tents in the middle of the forest. They’re called canopy cages. Six years ago the University of Tennessee and the U.S. Forest Service tested them at Blackberry Farm in Blount County, and now they’re being employed in the Smokies to help control the hemlock woolly adelgid, a tiny, nonnative insect pest that has been killing the park’s hemlocks for more than a decade. In addition to battling the infestation with soap sprays and soil-injected pesticides, the park has been releasing two species of “predator” beetles that prey on the hemlock woolly adelgid. To enhance its biological control program, the park recently added two more species of predator beetles to the mix.
Increase in bagworms threatens trees, foliage
(Apr. 19, 2013) - Years of drought conditions has caused an increase in bagworms, an insect that threatens the life of trees and foliage. At the Cedars of Lebanon State Park, it is pretty easy to find evidence of bagworms. The branches of the cedar trees are covered with bagworms, which eat the foliage and use the leaves to make their bags. "We have been getting a lot of calls about bagworms," said assistant state forester David Arnold. He says one of the main reasons for seeing an increase of bagworms in the state park is because of previous years of drought conditions.
Protecting Tennessee Trees
(March 2013) - Forests are complex ecosystems. And threats from invasive pests, drought and disease are to be expected, though not accepted without a fight. The Tennessee Department of Agriculture Division of Forestry (TDF) is at the forefront of the effort to protect the health of the state’s rural and urban forests.
