Restoration Articles

English Ivy (Hedera Helix) was brought to Oregon in the mid-1800’s as a way to remind early settlers of home. What started out as an innocent plan has come to represent one of the toughest problems Portland’s natural areas face today. It now invades more and more of our parks and will ultimately destroy our cherished tree canopy unless we remove it now. By allowing ivy to grow unchecked it will climb trees where it will mature, produce seeds, and continue the “seeds of destruction” by being transported by non-native birds.

Twenty years ago, we began partnering with a Multnomah County program called Alternative Community Service (ACS) for on-the-ground restoration efforts in the Terwilliger Parkway natural areas.
