What is an Invasive Species?

An invasive species is one that is not native.  Invasive species displace native plants as a result of being very aggressive, spreading rapidly, growing and dispersing easily.  This displacement alters native ecosystem processes and harms native plants and animals.  They out compete native species in areas where they have no natural predators and change the balance of the ecosystems we rely on.   

Examples of Invasive Species: Autumn Olive, Eurasian Phragmites, Black Alder, Purple Loosestrife, Canada Thistle, Black Locust, Russian Olive, multiple varieties of honeysuckle and Buckthorn just to name a few!
