Description:

Abstract:: This data set contains destructively sampled canopy fuel and tree biomass data from five study sites in the Interior West. We destructively measured canopy fuels in five conifer stands in conifer forest types important to land managers in the western USA, including ponderosa pine/Douglas fir in western Montana, lodgepole pine in central Montana, Douglas fir/lodgepole pine in Idaho, ponderosa pine in Arizona, and mixed conifer in the Sierra Nevadas in California. In each of these stands we established a 10 or 15 meter radius circular plot (depending on tree density), deliberately selecting plots in dense, crown-fire-prone areas, inventoried all trees within the plot including understory trees at least 0.3 meters (1 foot) tall, and then took apart the trees branch by branch to obtain biomass by size class and component (live or dead). For every branch, we measured green weight, length, and branch basal diameter. A subportion of the branches were destructively sorted by size class, so that biomass was weighed for foliage, and live and dead woody material 0-3 millimeters (mm), 3-6 (mm), 6-10 (mm), 10-25 (mm) and 25+ (mm) in diameter. A subportion of this material was oven dried to determine moisture content and correct the measurements to dry weight. These data were then used to develop regression equations to predict oven dry biomass by size class based on branch length and basal diameter. The equations were used to estimate biomass by size class for every branch in the stand. We chose dense stands that local land managers judged to be of high crown fire potential. A number of separate files are included, containing information on surface fuels, plot data, tree data and branch data.
Purpose:: We collected this data in order to develop and test indirect methods of estimating canopy fuel for use in wildland fire behavior prediction and fuel hazard mitigation.

Data_Quality_Information:

Attribute_Accuracy:

Attribute_Accuracy_Report:: Unless otherwise specified, the data were measured to the nearest unit specified. Vertical branch angle was measured to the nearest 10 degrees. Age was measured by ring counts at the stump (within 1 foot of the ground). Accuracy of the growth of the fresh weight of the branches was coarser for the larger branches than for the smaller.

Logical_Consistency_Report:

not applicable

Completeness_Report:

The first year (first 3 sites) the height at which the bole size reached a certain level was measured, but the second season (other 2 sites) they measured the diameter of the bole at every meter.

Distance, azmith, and X-Y-Z coordinates are missing for trees from study sites 1 and 2 because the data were lost.

On study site 5, trees outside the plot are included in the data because the original plan was to do a 15 meter radius plot, but it was dropped back to do a 10 meter radius plot. They were inventoried initially, but weren't destructively sampled.

Methodology:

Methodology_Type: Field
Methodology_Description:: See Field Sampling Procedures in the Methodology Citation and Study Plan (\Documents\Crown_Fuel_Measurement_Field_Procedures.pdf) enclosed in this data product.

Additional information: Large branches were systematically sampled (approximately 5-10% of branches removed from each tree). The small branches were neither systematically or randomly sampled. The selection was arbitrary in an attempt to get a representative sample of small branches.
