Portland Parks & Recreation invites you to take part in the 15th annual No Ivy Day

POSTED OCTOBER 24, 2018 

(Portland, OR) –

Portland Parks & Recreation (PP&R)’s No Ivy League welcomes volunteers across the region to take part in the 15th annual No Ivy Day. Volunteers will focus on removing this invasive species from Portland’s treasured parks and natural areas on Saturday, October 27, 2018.All are welcome to join in on restoration events hosted by PP&R and partners citywide, followed by a celebration thanking community members for their participation. 

“Ivy is an invasive species, killing trees and other native species. Thanks to dedicated community volunteers, we’re getting ivy out of our parks and natural areas,” says Portland Parks Commissioner Nick Fish." 

  • WHAT: No Ivy Day, a Portland-area series of volunteer events focused on removing harmful ivy and other invasive plant species from Portland’s green spaces. 
  • WHEN: Saturday, October 27, 2018, 9am-12pm. Help rid Portland parks and natural areas from a harmful invasive plant species by taking part in citywide volunteer restoration events to remove English ivy.  
  • WHERE: Citywide and across the metro Portland area including: Baltimore Woods Natural Area, Forest Park, Hoyt Arboretum, Indian Creek Natural Area, Gateway Green, Johnson Lake, Marquam Nature Park, Marshall Park, Mt. Tabor Park, Pier Park, Terwilliger Parkway, Woods Memorial Park and many more sites. More info and registration details are available here
  • Party!  Celebrate after you work, from 12:30pm-1:30pm with raffles and food at three sites:
    • Forest Park (Lower Macleay entrance at 2960 NW Upshur)
    • Terwilliger Parkway (SW Terwilliger Blvd & SW Hamilton St)
    • Mt Tabor Park (across from visitor center at picnic area A) 

“We hope our amazing volunteers show up like they have in the past, such as last year when more than 350 people of all ages took part,” says PP&R Interim Director Kia Selley. “No Ivy Day in 2017 resulted in the removal of more than three acres of ground ivy - and cleared the harmful vine from a whopping 130 trees! But I’m betting that Portlanders can exceed even those impressive totals this time.”

About invasive ivy

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. 

Portland Parks & Recreation 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 Parkway, Marquam Nature Park and Forest Park have seen vast improvements in tree health in places where ivy was recently cleared.
