Report Shows Tennessee Land In Forests Stable, Yet Changing In Composition (May 27, 2009)
USDA. FS. Southern Research Station.
The amount of forest land in Tennessee remains stable, but is changing in terms of species, age and ownership according to a newly released report -- Tennesee's Forests 2004 (see section on Invasive Plant Species on page 42). Among concerns was the fact that 52 percent of all forested plots sampled from 2000 to 2004 contained at least one non-native, invasive plant species. These plants have the potential to severely disrupt the ecological characteristics of a forest, such as altering soil characteristics or outcompeting native species for water, nutrients, sunlight and even space.
