Invasive Species Alert List
Tennessee Exotic Pest Plant Council.
These are plant species for which more information is needed to determine their invasiveness in the state. Some may not yet occur in Tennessee but are found in nearby states. These species have invasive characteristics such as rapid growth and high fruit/seed production and are known to be invasive in similar habitats to those found in Tennessee or are listed as a severe threat in adjacent states or pose substantial management difficulties where they occur. Through this list, TN-EPPC hopes to gather information about their spread in the state. Contact us to Report Invasive Plant if these species are sighted.
Thousand Cankers Disease
Tennessee Department of Agriculture.
Thousand Cankers Disease (TCD) poses a serious problem to the health of the black walnut tree. Tennessee Department of Agriculture officials urge area residents and visitors to help prevent the spread of TCD:
- Don't transport firewood, even within Tennessee.
- Don't buy or move firewood from outside the state.
- Watch for signs of infestation in your walnut trees.
If you suspect your walnut tree could be infected with TCD, refer to the TCD Symptoms Checklist and online TCD Report Form to alert state plant and forestry officials, or call TDA's Consumer and Industry Services Division at 1-800-628-2631.
White-nose Syndrome in Tennessee
Tennessee Bat Working Group.
White-nose Syndrome is a mysterious disease that is killing bats across the northeast United States. WNS was first discovered in New York in the winter of 2006/2007, since then the syndrome has spread dramatically and can now be found in Tennessee. Many research projects are underway to help in the fight against WNS, from researching fungicides to modeling the spread and affects of the syndrome. If you would like to help there are many ways in which you can:
- Report any unusual bat activity (bats flying in the daytime) or unexplained bat deaths to your regional TWRA office. Or check out the Report a Bat Link on this website.
- Donate to a number of funds collecting money for WNS research (see National Speleological Society and Bat Conservation International pages below).
- Adhere to state and federal cave closure advisories.
- Encourage state and federal agencies to assist in WNS research and monitoring activities.
