Activities to prevent and control invasive plant and animal species that severely impact the lands and waters of the United States, including resources managed within the National Wildlife Refuge System, have become a priority for the U.S. Fish and Wildlife Service as we expand our efforts to conserve and protect our nation's native fish and wildlife habitats. Introductions of these non-native species often degrade wetland or upland habitats and the wildlife that depends on them by out competing and replacing native vegetation that is critical for food, breeding, or cover.

The Partners for Fish and Wildlife program is working with several partners in NH, MA and RI to restore wetland and riparian habitats that have been degraded by the introduction of non-native purple loosestrife (Lythrum salicaria), Japanese knotweed (Fallopia japonica) and common reed (Phragmites australis). On selected upland sites the Partners Program is working collaboratively with project partners to control infestations of black and pale swallow-wort (Vincetoxicum spp.), common and glossy buckthorn (Rhamnus spp.), and non-native honeysuckles (Lonicera spp).
