BES names several Alien Plant Invaders and asks for help controlling them

With the busy summer construction and project season many of us are spending more time landscaping and gardening. Whether you are adding landscaping to the exterior of your development project or spending some quality time with your yard or someone else’s, the Bureau of Environmental Services names several Alien Plant Invaders and asks for help in stopping their spread. Unfortunately some of these invader plants end up being sold in nurseries or garden centers. Look for these plants and read the website links beside them to find out more.

Message from BES: Invasive species affect us all. They damage our forests, streams and rivers, and property. Nationwide, damages associated with invasive species are estimated to be $120 billion each year. In Oregon, the control of invasive weeds and the cost of the damages they create amounts to about $125 million each year. We know that it costs a lot less to control new invasive plants before they become infestations, so we need everyone’s help. Find out more about the problems caused by invasive species and why Environmental Services works to stop their spread.
