The USDA Forest Service's Forest Inventory and Analysis program conducts an inventory of forests of the United States including down woody materials (DWM). In this report we provide the rationale and context for a national inventory of DWM, describe the components sampled, discuss the sampling…

A common component of fire incident reports and prescribed burn preparations is an estimate of the energy that was or will be released by the fire. Typically, this is based on the energy released by combustion of the fuel load, reduced to account for the energy that is required to evaporate…

A model for fire-induced heating in tree stems is linked to a recently reported model for tissue necrosis. The combined model produces cambial tissue necrosis predictions in a tree stem as a function of heating rate, heating time, tree species, and stem diameter. Model accuracy is evaluated by…

Measurement error in the Forest Inventory and Analysis work of the Pacific Northwest Station was estimated with a recently implemented blind plot measurement protocol. A small subset of plots was revisited by a crew having limited knowledge of the first crew's measurements. This preliminary…

In 2000, the North Central Research Station initiated the Forest Productivity Integrated Research Program (North Central Research Station 2001). This program combines the efforts of scientists from across the Station's 13 research work units to examine the current condition of the forests in the…

Temperature, light, wind, and precipitation were measured in the understory of managed and unmanaged northern hardwood forests in the Upper Peninsula of Michigan from 1995 through 2001. These measurements provide a baseline of information to compare the microclimate under managed and unmanaged…

Vegetation data from the 1997 inventory of non-Federal forests in western Oregon were examined to assess the abundance of invasive nonnative plants detected by the inventory. Inventoried plants were the more common, identifiable species; composites and graminoids were underrepresented. Nonnative…

Weight per unit area (load) estimates of Down Woody Material (DWM) are the most common requests by users of the USDA Forest Service's Forest Inventory and Analysis (FIA) program's DWM inventory. Estimating of DWM loads requires the uniform compilation of DWM transect data for the entire United…

Phenology, the study of how plant or animal developmental stages relate to the organism's surrounding climate, is a well established discipline with roots dating back more than 2000 years (Hopp and Blair, 1973). For example, correlations are often noted between budbreak or first blossom and…
