Join staff from Vancouver’s Water Resources Education Center to pull English ivy in Marine Park, 4501 S.E. Columbia Way, Vancouver, from 9:30 to 11:30 a.m. May 13. Volunteers will cut ivy from tree trunks, pull ivy from the soil and spread bark mulch, rain or shine. Gloves, tools and snacks will be provided. Ivy pulling will take place primarily off the main walkway, where the terrain is uneven and slightly sloped. Registration is required at cityofvancouver.us/publicworks/page/marine-park-ivy-pull.
