What Are Invasive Plants and Why Are They a Concern?

They are non-native plants . . . They are a concern because they may . . .

When one species takes over a large area it can also alter hydrological patterns, fire regimes and soil chemistry, moisture-holding capacity, wildlife habitat, and erodibility. All told, invasive plants cause billions of dollars of damage each year and tens of millions of dollars are spent annually trying to control them. One of the more notorious examples is kudzu, a quick-growing vine that was introduced in the Southeastern US as a quick-growing groundcover for disturbed areas like highway embankments. A native of Asia, it has now spread from East Texas to New England where it has smothered 7 million acres of forest.
