Restore Forest Park

STATUS380 of 2,600 acres treated through support from Metro

Half of Forest Park is currently maintained in good or excellent ecological condition; about 2,600 out of 5,200 total acres. In the other half of the park, invasive plants are a primary threat. In partnership with the Forest Park Conservancy, Restore Forest Park is transforming the park’s ecological health through invasive plant removal and native plant revegetation for wildlife species.

Project Description
Invasive species removal efforts have been ongoing for years in Forest Park. While these efforts have tangible results, they have not been comprehensive for a landscape of this scale. In 2015, with strong leadership from PP&R, support from The Forest Park Conservancy and with funding from Metro, phase one of Restore Forest Park began with restoration of over 200 acres in the Balch Creek subwatershed.

Phase two of Restore Forest Park began in spring 2016 through a unique partnership with PP&R, Metro, the Bonneville Power Administration (BPA) and the Forest Park Conservancy. Efforts concentrate on restoring forested habitat and creating an oasis for pollinators (birds, bees and butterflies) under BPA’s transmission lines that run through Forest Park. This 166-acre project located in the Northern Management Unit of Forest Park will remove invasive species, improve native plant biodiversity, increase wildlife habitat, and connect existing restoration areas.

Efforts will include

  • Removal of invasive species such as blackberry and Scotch broom in BPA’s powerline corridor
  • Pollinator habitat enhancement with native shrubs, wildflowers and grasses
  • Treatment of ground cover invasives under forested canopy, predominantly ivy and clematis

Treatment Approach
In April 2016, phase two of Restore Forest Park began. In accordance with our Integrated Pest Management Policy—the City of Portland has established a treatment protocol that has perfected the herbicide combination and treatment timing so that initial treatments are extremely effective. State-licensed herbicide applicators will use selective herbicide application for this site.

This project has been made possible through funding from Metro and BPA, and in partnership with the Forest Park Conservancy.
