The Framework provides broad and consistent strategic direction across all Forest Service Deputy Areas and agency programs. The Invasive Species Systems Approach (ISSA) identifies the elements and actions of the Framework that all programs and units within the National Forest System, Research and Development, and State and Private Forestry should take, as appropriate, in addressing invasive species.

What Makes Invasive Plants So Invasive?
- It's believed that birds, insects, and even humans tend to spread invasive plants by dropping wayward seeds that take root. Some invasive plants spread through extensive underground networks of root-like plant parts called rhizomes. Some plants' rhizomes are so widespread that attempting eradication by digging them up is usually fr…
Examples of Invasive Plants
- Classic cases of invasive plants forming such a monoculture can be seen in entrenched stands of Japanese knotweed and purple loosestrife, both of which have notoriously vigorous rhizomes. While Japanese knotweed and purple loosestrife have become poster children for invasive plants because they are so widespread, there are many other, lesser-known examples of rhizomatous, alien plants that form monocultures,1such as common butt…
Invasiveness Is Not Universal

Conditions vary wildly in a country as big as the U.S. An exotic plant capable of swallowing the South may be incapable of spreading very far in the North, due to the colder climate. In fact, there are many factors to keep in mind before prejudging a plant for invasiveness. Sometimes, the species plant …
