Join city staff from the Naturespaces program and volunteers from the Adopt-A-Park program from 9 to 11:30 a.m. Dec. 10 to pull invasive English ivy in Behrens Woods Urban Nature Area, 3005 S.E. Bella Vista Place, Vancouver. The focus will be removing ivy from on and around trees to minimize impacts to forest health. The event will happen rain or shine. Training, gloves, tools and snacks will be provided. Ivy pulling will take place primarily off of established trails, and the terrain will be uneven and slightly sloped. Activities will include cutting ivy off of tree trunks, bending over to pull ivy free from the soil and shoveling and spreading bark mulch. Participants will also hear more about Naturespaces and Adopt-a-Park programs and learn about native plants and birds.
