Invasive Plants

Invasive plants threaten our parks, beaches, shorelines, and green spaces, and Seattle Parks needs your help in the fight! These aggressive invaders crowd out native plants, damage the habitat our native wildlife needs to survive, and reduce the enjoyment of public spaces. Together we can control these invaders and preserve our City’s natural treasures.

Loosestrife Out! Project

Garden Loosestrife Purple Loosestrife and Garden Loosestrife are threatening to dominate shorelines and damp areas of Lake Washington and several parks.

Seattle Parks and Recreation received a grant from Washington State Department of Ecology to battle these aggressive weeds.

These plants aggressively establish colonies in wetland areas and pose a serious threat to the health and integrity of shoreline plant communities and ecosystems that support salmon and other animal, bird and fish species.

Once established, these weeds don't pull out easily and the shoreline and flooded sites make diggin or any other mechanical methods impossible with existing resources. There are no boilogical controls currently available for Garden Loosestrife.

Therefore, the most effective way of managing and eradicating this infestation is the use of an approved aquatic herbicide formulation in a spot application.
