| Whole-tree (WTH) and tree-length harvested (TLH) stands were evaluated 18 years following treatment. Biomass equations were developed for 12 species on the research site. Biomass was estimated using developed equations and stem inventory data. Stem density estimates were 4,813 stems/ha for WTH and 4,816 stems/ha for TLH. Quaking aspen stem density was higher (P = .019) on TLH than WTH. American beech (P = .031) and birch (P = .095) stem densities were higher on WTH than TLH. Differences between treatments in species biomass were found for American beech ( P = .098), gray birch (P = .043), and quaking aspen (P = .043). Nutrient concentrations and content of aboveground tree biomass were determined by species and component. Foliage calcium content was higher (P = .084) for TLH than WTH. Total potassium content was higher (P = .091) for TLH than WTH. Results suggest no apparent differences between WTH and TLH on the stem density, species composition, biomass, nutrient concentration and contents of stands in this study. |
