OFFENSES

Purple loosestrife quickly crowds out most native vegetation in marsh, sedge meadow, wet prairie, and bog communities, creating a monoculture that provides little food or shelter for native wildlife.

MANAGEMENT TECHNIQUES

Chemical control: For large infestation sites, glyphosate herbicides are sprayed directly onto the invasive plants.


Biological control: The plant's natural enemy, Galerucella beetles, are introduced into the area to prevent population explosions of purple loosestrife.
