Tree Planting

Native trees are critical to the health of our region

Trees improve air quality and reduce greenhouse gases, shade creeks and streams cooling water for threatened salmon. Trees reduce erosion and filter pollutants, improving water quality and providing important wildlife habitat.

Our nearby forests provide environmental, economic and social benefits throughout the Puget Sound region and without proper care, they may be lost to future generations.

That’s where Carter Subaru and Carter Volkswagen come in.

Planting a Forest…One Test Drive at a Time

Since 2008, in partnership with the Mountains to Sound Greenway, Carter Subaru and Volkswagen have planted nearly 200,000 native trees and shrubs in the Greenway as part of their On the Road to Carbon Neutral program.

Every time you test drive a Subaru at Carter Motors, they will plant one tree in your name in the Greenway. Buy a Subaru and they will plant three more during the Greenway’s tree planting season.

Tree Planting Season

The Greenway Trust hosts tree planting event every fall and winter. They are excellent for individuals, families, groups, and work teams. No experience required!
