Portland Parks & Recreation Presents No Ivy Day, 10/24/15

Community Volunteer Efforts Citywide to Remove Invasive Species

(Portland, OR) –

Portland Parks & Recreation (PP&R)’s City Nature division, the No Ivy League and volunteers across the region are proud to take part in the 12th annual No Ivy Day.  Volunteers will focus on removing this invasive species from Portland’s treasured parks and natural areas on Saturday, October 24, 2015.

“I am very grateful to our volunteers, who are helping to care for our parks and natural areas,” says Portland Parks Commissioner Amanda Fritz. “The No Ivy Day is a grassroots effort of neighbors which has visible, positive effects on our green spaces, and I look forward to this partnership continuing - even bigger and better.”

WHAT: No Ivy Day, a citywide series of work parties to remove invasive ivy from Portland parks and natural areas

WHERE: Citywide, including Forest Park, Marquam Nature Park, Terwilliger Wildlands, Woods Memorial Park, Marshall Park, Elk Rock Island, Gabriel Park, Baltimore Woods Natural Area, Hoyt Arboretum, River View Natural Area, Rosemont Bluff, Sylvania Nature Area Park, the Springwater Corridor Trail and many more. Find out more and sign up here.

WHEN: Saturday, October 24, 2015, 9am-12noon.  Help rid PP&R parks and natural areas of invasive ivy!  Take part in city-wide volunteer restoration events and have a blast with friends and neighbors.

Party!  Celebration to follow at multiple sites from 12:00-1:30 including the No Ivy League headquarters at Lower Macleay Park, NW 29th & Upshur. Come for free food and family fun!

  • Lower Macleay Park, 2960 NW Upshur
  • Marshall Park, SW 18th Drive (by the new playground)
  • Terwilliger Park, SW Terwilliger Blvd and SW Hamilton St
  • Springwater Corridor Trail at 128th

During last year’s No Ivy Day, more than 300 volunteers removed more than 65,000 square feet of ivy, blackberry and clematis, planted and mulched nearly 400 trees and shrubs and built 50 feet of trail.  The hope is to accomplish even more this year.

All volunteers are invited to take part in a celebration after the citywide work parties featuring lunch, free T-shirts while they last and a chance to meet fellow ivy pullers.

“The efforts of volunteers and the No Ivy League are essential to the health of our beautiful parks and natural areas,” says Portland Parks & Recreation Director Mike Abbaté.  “We appreciate the continued engagement of our PP&R staff and our valued community partners to remove this invasive plant“.

The non-native English ivy (Hedera hibernica and Hedera helix) is a pervasive and unwelcome guest in our parks and natural areas.  The vines overcome native plant species, and mature ivy vines may threaten trees in many of our forests.  Ivy removal work parties run from 9:00 AM to 12pm, followed by gatherings for food and celebration from 12:00-1:30 (see above).

The celebration will feature free T-shirts while they last, and a chance to meet with other volunteers.  All are welcome to show support for our native ecosystem by joining a volunteer restoration event at one of the many sites throughout the region or by registering to host your own No Ivy Day site. Please check the No Ivy Day link for more information here.

Portland Parks & Recreation City Nature experts say it is important to remove maturing ivy during the fall to reduce the amount of seed produced through the winter, slowing its spread to unaffected areas.  Portland Parks & Recreation’s Terwilliger Wildlands, Marquam Nature Park and Forest Park have seen vast improvements in tree health in places where ivy was recently cleared.
