About this file

This document is an Attachment (10) detailing a Small Fuels Treatment Photo Series for the BCLH Stewardship IRSC Phase 3 project in the Willamette National Forest's Detroit Ranger District. The document provides photographic evidence of post-treatment fuel loadings with detailed quantitative measurements across three diameter classes: 0.25" to 3.0" (4.5 tons per acre), 3.1" to 9.0" (6.8 tons per acre), and 9.1" to 20" (13.2 tons per acre).

The images demonstrate fuel reduction treatments where minimum forest standards have been met, with residual down wood greater than 16" in diameter retained on-site. Each photo includes a triangular marker and accompanying data table showing the tons per acre for different wood diameter ranges. The documentation indicates that while smaller diameter fuels have been effectively reduced, some images show fuel loading in the 9.1" to 20" class exceeding minimum standards, which is noted in the accompanying text. This photo series serves as a visual guide for assessing adequate levels of fuels treatments in forest management.

ATTACHMENT 10 – SMALL FUELS TREATMENT PHOTO SERIES

Photo series examples of post-treatment fuels loadings

Page 2 of 3 Detroit Ranger District

The following photos depict post-treatment fuel loadings with tons per acre caluclated by planner transects and tallied by size class and can be used as a guide to determine adequate levels of fuels treatments.

Diameter Tons Per Acre 0.25” to 3.0” 4.5

3.1 to 9.0” 6.8

9.1 to 20” 13.2

In this photo series all minimum fuels treatment objectives have been meet and residual down wood greater than 16” in diameter has been retained on site.

Diameter Tons Per Acre

0.25 to 3.0” 0.9

3.1 to 9.0” 7.0

9.1 to 20” 25.1

In this photo the .25” to 3.0” and 3.1” to 9.0” fuels have been reduced to meet Forest Standards and Guides, but fuel loading in the 9.1” to 20” class are above the minimum standard.
