An Ecological Threat:

Purple Loosestrife prefers moist soils and shallow waters where it competes with native wetland plants. It will adjust to varying light conditions and water levels. It has been widely planted as an ornamental where it escapes to nearby water ways. This species can spread rapidly and destroy ecosystems that are important for other plants and animals as well!

There Is a Solution:
-The Galerucella beetle is a biological control that eats Purple Loosestrife.
-Grow these beetles and release them to stop the spread of Purple Loosestrife.
-Receive equipments and instructions FREE from the County's AIS Coordinator.
-This is a great family activity that helps preserve the wetlands in Washington County.
