The Exotic Plant Problem: Defending Your Lands from an Unfriendly Takeover Part II
Exotic pest plants are marching across the southern landscape and occupying our lands. These foreign invaders-often called non-native, alien, or noxious weeds-occur as trees, shrubs, vines, and grasses. Some have been introduced into this country accidentally, but most were brought here intentionally as omamentals or for livestock forage. They arrived without their natural predators of insects and diseases that tend to keep most plants in a natural balance, and they are now essentially free to spread without too much opposition, except from control and eradication measures applied by landowners and managers trying to defend their property from an unfriendly takeover.
