Spatial representation of many forest attributes across the Interior
West Region have been produced using a hierarchical modeling procedure.
These forest attributes include: forest/nonforest mask, basal area,
basal area by ponderosa pine species, biomass, crown cover, forest type/group,
growth, quadratic mean diameter, stand age, stand density index, trees
per acre, volume, and weighted stand height. The modeling procedure
was based on a nonparametric approach that attempts to extract patterns
between FIA plot data and several layers of geospatial predictor variables
- principally from MODIS imagery.
