Portland Parks & Recreation’s (PP&R) No Ivy League invites volunteers for the city’s 21st annual No Ivy Day events on October 26. When left unchecked, ivy vines can grow to the size of large tree branches, harming native trees and reducing biodiversity in our valued Northwest ecosystems.
Join a volunteer event at one of the many sites across the Portland metro area to show your support. Since 2011, PP&R volunteers have removed nearly a quarter million square feet of ivy from Portland’s parks and natural areas. Along the way, they’ve spotted hawks, salamanders, hummingbirds and other amazing wildlife. Volunteers have also worked with staff to remove trash from our beloved green spaces and plant new, beneficial, native vegetation.
Events will involve hiking and working on uneven ground, so wear sturdy, closed-toed shoes, and bring a water bottle and snacks. PP&R will provide project instruction, tools, gloves, water and snacks.
