The environment of the Greenway offers a distinct and unique blend of different ecological areas, from urban- and marine-, to rural- and high-elevation environments, home to numerous plant and animal species, and offer a variety of benefits and uses. In addition to providing aesthetic, economic, recreational, and ecological benefits, these areas enhance and improve the quality of life of Greenway residents.

Greenway Trust Ecological Restoration

An ambitious environmental restoration program brings volunteers and conservation corps crews to teach participants about the importance of healthy ecosystems and to remove invasive plants such as English ivy, holly and Himalayan blackberry, plant native trees and shrubs and improve natural areas for wildlife and salmon habitat.

Native trees, grown at the Greenway tree nursery and planted in public parks and forests, improve air quality, provide shade for salmon in creeks, reduce erosion, filter pollutants and provide important wildlife habitat.

A Greenway restoration project includes several years of care for newly-planted trees to ensure their best chance of survival.
