Girdling Trees to Create Snags
(Activity: CWD Creation)
Project #002 - Girdling Trees to Create Wildlife Snags and Down Wood
This Stewardship Project requires services for removing bark and cambium of live trees (girdling) at various locations on the Clackamas River Ranger District of the Mt. Hood National Forest in Clackamas County, Oregon. This girdling is meant to kill the trees and create a wildlife snag in the short term and Down Woody Debris (DWD) within ten years.
Trees to be girdled are in partially harvested young plantations or in un-harvested riparian reserves. This project work will be done within the boundaries of payment units of the Hot Thin Stewardship Contract or in the un-treated riparian reserves directly adjacent to the payment units. The boundaries of these payment units will be designated with blue timber harvest signs, orange tree tags and white paint.

*Due to safety issues or natural variation in stand sizes, there may be instances where cut tree sizes would be above or below this range. Trees chosen for DWD creation should be representative of some of the larger DBH’s of the stand, but not the “biggest and best”. However, in most cases DBH range should be accurate.
