National Invasive Species Awareness Week!



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 enjoying all Skamania County has to offer, 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!

2016 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 2016 weed list after a public hearing on February 3th.  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.
