Retreat - Noxious Weed Information

What are noxious weeds? Why should we care?

Noxious Weed Definition: reprinted with permission from CWMA.

Noxious weeds are plants that are not native to our area. Most have come from Europe or Asia either accidentally or as ornamentals that have escaped. These plants have an advantage because the insects, diseases, and animals that would normally control them are not found here. Because these plants have developed specialized mechanisms to survive, they are able to spread at an alarming rate.
