About this file
This is an amendment to the Crest Switchback DxP Stewardship Integrated Resource Stewardship Contract (IRSC) that documents forest fuel load data collected during common stand examinations on November 7, 2022.
The amendment presents two distinct datasets for downed woody material. The Brown's Transect Compilation provides downed woody weight and volume measurements per acre categorized by size class (0-0.24 inches, 0.25-0.99 inches, 1-2.99 inches, and 3+ inches), with the 3+ inch class further subdivided into sound and rotten categories. Total measurements across all classes show 79.9 tons per acre with standard deviation of 86.5 tons per acre, and 6,985.2 cubic feet per acre with standard deviation of 7,440.3 cubic feet per acre. The FFE-FVS Initial Dead Fuel Loads table presents measurements for five fuel categories (<1 inch, 1-2.9 inches, 3-5.9 inches, 6-11.9 inches, and 12+ inches) across fields 1 through 5, with values ranging from 3.0 tons per acre for the smallest diameter class to 47.7 tons per acre for the largest diameter class. Standard deviations are provided for all measurements to indicate data variability.
