West Multnomah County is fortunate to have a large amount of lush native forest land.  These forests support a wide array of wildlife, keep our streams flowing strong and cool, and store carbon to improve air quality.  Thinning a crowded forest will improve the health of the stand and the habitat.  A District conservationist can help you design a stewardship plan to restore forest health and offer free technical advice on how to control invasive weeds such as English ivy, scot’s broom, and Armenian blackberry, which can displace trees and native plants. You may also be interested in technical advice on making your home and woods “fire-safe,” enhancing wildlife habitat, maintaining forest roads and stream crossings, and increasing your land’s profitability.  If you want to create or improve streamside areas in your woods, visit the Healthy Streams page.

Our focus in the woods fall into these categories:

Tree thinning & health

Invasive Weeds

Fire-Safe your home

Wildlife Habitat
