    Description

    Five economically important Appalachian hardwood species were selected from five ecoregions in West Virginia. A nonlinear extra sum of squares procedure was employed to test whether the height-diameter relationships, based on measurements from the 2000 inventory from West Virginia, were significantly different at the ecoregion level. For all species examined, the null hypothesis was rejected indicating that at least one of the ecoregion specific parameters was not equal to zero. In addition, 56 percent of the paired ecoregion tests indicated significant height differences. Across all species and ecoregion combinations, average height error ranged from ?3.6 to 7.6 ft for the statewide model.
