Protecting Native Habitats

The principles of Geotourism seek to protect and enhance destination appeal, which sometimes seem to be contrary goals. As more people explore the region, the waterways and forest lands face the risk of infestation from nonnative plants or species that can be introduced by boaters and hikers from their tents, shoes, and gear that may be carrying seeds or other organisms. Well-meaning businesses, homeowners, and agencies also contribute by planting nonnative ornamentals that can choke out the native species which serve as important habitat for wildlife.

Sometimes these nonnative plantings date back hundreds of years. It is not uncommon while hiking backcountry trails to see flowering bulbs or Yucca plants signifying the location of pioneer homesteads. European settlers often brought plantings from their homelands to the frontier. While these plants add to the heritage interpretation of the land, other plants such as honeysuckle, privet, and stiltgrass spread rapidly and can overtake native tree survival; a potential threat to the future of the forests.

Recreational boating and fishing are also impacted by the spread nonnative species. The Tennessee River system has experienced areas clogged with hydrilla or infested with zebra mussels. Most recently, portions of the Tennessee River have been invaded by several species of carp including the infamous “jumping” Asian Carp. The pressure to keep these invaders from crowding out spawning areas and food sources is an ongoing battle being managed by private and public agencies.

The appeal of the Tennessee River Valley is the incredible beauty, recreation, and heritage of the region. Managing the ecosystem is an ongoing effort. We applaud the work of the businesses and public agencies that educate visitors about simple ways to protect the watershed from spreading invasives.
