Invasive Species

What are Invasive Species?

Any species, including its seeds, eggs, spores, or other biological material capable of propagating that species, that is not native to that ecosystem; and whose introduction does or is likely to cause economic or environmental harm, or harm to human health.  Invasive species can come from other regions of the U.S., or even another country. They become a problem because they are beyond their natural range and there are no natural predators to control the new species population growth. Plants, animals, or even microbes can be classified as invasive species. There are many modes of transportation (wind, water, animal, or human).

The Concern:

Invasive species are being introduced and spread at an ever-increasing rate. Once established, they can permanently alter the soil structure, disrupt native plant communities, reduce dependent wildlife populations, and impact long-term forest productivity.

The Objective:

To slow the spread of existing infestations and minimize the risk of introducing new infestations of damaging invasive species into our forests.

Invasive species move much farther and faster with our help. Here is a training video that the United States Forest Service put together with the help of many partners to educate road maintenance crews.
