Project #003 - Girdling Trees to Create Wildlife Snags

This conservation project requires services for removing bark and cambium from 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 tree and create a wildlife snag in the short term and DWD within ten years.

Trees to be girdled are in partially harvested forests.  This project work will be done within the boundaries of units 8, 10, 11, and 12 of the Spoon Thin Stewardship Project.  The boundaries of these units will be designated with blue timber harvest signs, orange tree tags and white paint.

The Contractor shall furnish materials, labor, supervision, transportation, and all supplies not provided by the Government, which are required to complete the project.  The Government shall provide unit maps, blank tree registers, and aluminum signs.  The Contractor will fill out tree registers and map girdled trees on unit maps prior to final inspection. 

Target Tree Details

*Due to safety issues or natural variation in stand sizes, there may be instances where girdling would need to occur above or below this range.  Trees chosen for girdling should be representative of the largest DBH’s of the stand, excluding residual old-growth.
