Get Dirty for Earth Day: Noxious Weed Events This Weekend

Dig into noxious weed control at home with events and invasive plant volunteer trainings

Olympia—April 19, 2015— Earth Day is April 22, so dig in to control noxious invasive weeds this weekend or all month with events and trainings. Earth Day is a great reminder for us to remove noxious invasive weeds in our gardens and natural areas and restore our native plant and wildlife habitat. Learn how to remove noxious weeds at local events or by training to be a citizen scientist invasive species volunteer. Or tackle them on your own (with optional help from your noxious weed control board or district).

“You can celebrate Earth Day by spending a little time getting rid of your noxious weeds,” says Alison Halpern, executive secretary of the Washington State Noxious Weed Control Board. “Replace those invasive plants in your yard with native or non-invasive ornamental plants that provide food and shelter for birds, bees, butterflies, and other critters. You get to enjoy time outside, get some exercise, and feel great about helping to make your world a better place, one plant at a time.”

Noxious weeds are non-native plants that become highly destructive, or difficult to control by cultural, mechanical, or chemical methods. They reduce crop yields, destroy native plant and animal habitat, damage recreational opportunities, clog waterways, lower land values, and some can poison people and livestock.

The Washington State Noxious Weed Control Board is distributing pollinator-friendly Bee-U-tify seed packets, which contain a blend of annual and perennial native and nonnative but non-invasive plants that are great for yards and gardens.  You can do a good deed by removing the weeds, planting these seeds, and then feeding the bees. To receive a free seed packet (while supplies last) and a brochure about bee-friendly noxious weed control, email us at or contact your county weed board.

Citizen Science Early Detection Rapid Response Volunteer Training

Pacific Northwest Invasive Plant Council classes in Kelso, North Bend, Olympia, Seattle, and Vancouver through June. Volunteers learn to identify invasive plants and to conduct invasive plant surveys.

National Invasive Species Awareness Week!

playcleango_webbig Invasive species cause millions of dollars of damage every year to our agricultural, cultural, and natural areas.  They crowd out native species and are a huge detriment to biodiversity. One of the best ways to combat invasive species is to prevent their establishment in the first place.  So when you are out hiking this week in the beautiful, spring-like weather, take a few steps to do your part in preventing weeds from invading your favorite trail or park: 1) Brush your boots, bike, or gear before and after you recreate 2) Keep pets leashed and stay on the trail 3) Volunteer to help remove invasive plants in your favorite natural area 4) Report any invaders to your local Noxious Weed Program 5) Tell your friends about how to prevent invasive species!

2015 Noxious Weed List for Skamania County has been adopted!

Every year, county weed boards review the state weed list and create a county-specific list based on local conditions and priorities.  In addition to ALL Class A species and all Class B species designated for control by the state, the county weed board requires control of certain Class B and Class C species that are a local priority.

The Skamania County Weed Board adopted the 2015 weed list after a public hearing on February 4th.  Those species selected are required, by law, to be controlled.  Those not selected are still considered noxious weeds and a threat, and should be contained or controlled when possible. For more information on the state or county noxious weed lists, please call the Skamania County Noxious Weed Control Program.
