Have fun and help protect Portland’s treasured parks and natural areas

(Portland, OR) –

Portland Parks & Recreation’s No Ivy League invites you to volunteer for our 19th annual No Ivy Day events citywide on October 29, 2022. When left unchecked,  ivy vines can grow to the size of large tree branches (see below photo!), harming native trees and reducing biodiversity in our valued Northwest ecosystems.  

Portland Parks & Recreation coordinator Mary Verrilli poses with a giant log of ivy at Lower Macleay Park on a sunny day. She's wearing a purple stocking cap and purple sweatshirt. The log is thicker than her leg and almost up to her shoulders from the ground up.

You can help! Come show your support by joining a volunteer event at one of our sites throughout the region. Since 2011, PP&R volunteer efforts have removed nearly a quarter million square feet of  ivy from Portland’s parks and natural areas. We’ve also seen hawks, salamanders, hummingbirds, and other amazing wildlife. Volunteers have worked with staff to remove many bags full of trash from our treasured green spaces and to plant new, beneficial, native vegetation.

Save the date for No Ivy Day - October 29, 2022
