Annual Invasive Species Survey

Become a scientist for the day at Columbia Springs during the Invasive Species Survey. Go off-trail in Columbia Springs’ 100-acre natural area while learning about invasive species and scientific survey techniques. Groups of volunteers will search the landscape for three different invasive plant species while collecting important data. No experience is necessary! You’ll help Columbia Springs staff measure the abundance of species like English ivy and your contribution will support the maintenance and management of this popular wildlife and recreation site. Training in basic survey and sampling techniques will be provided, and here’s the important thing: free snacks are provided, too!

The Invasive Plant Species Survey will be held on Saturday, Feb. 18, from 1:30 to 4:30 p.m. at Columbia Springs, 12208 S.E. Evergreen Hwy. in Vancouver. There’s no charge to participate. Dress for the weather; gloves and boots are good. Teens are welcome. For more information, call Erik Horngren at 360-882-0936, send an email to, or see the Stewardship Saturdays page on Columbia Springs’ website at
