Falling Trees for Down Wood
(Activity: CWD Creation)
Project #002 - Falling Trees for Down Wood
This conservation project requires services for the cutting of live trees to create Down Woody Debris (DWD) at various locations on the Clackamas River Ranger District of the Mt. Hood National Forest in Clackamas County, Oregon.
Trees to be cut are in partially harvested young plantations or in un-harvested riparian reserves. This project work will be done within the boundaries of the units of the K9 Thin timber sale or in the un-treated riparian reserves directly adjacent to the units.
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 and blank tree registers. The Contractor will fill out tree registers prior to final inspection.

*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 the best.” However, in most cases DBH range should be accurate.
