Diameter Distribution, Stem Volume and Stem Quality Models for Grey Alder (Alnus Incana) in Eastern Finland [link]Paper  doi  abstract   bibtex   
Stand-level predictions of basal-area diameter distributions, height, positions of lowest dead and live branches and stem-rot are provided for grey alder in eastern Finland. The usability of models was tested by calculating the accuracy of predicted volume characteristics. The data were collected from 33 stands situated in the provinces of North Karelia and North Savo in eastern Finland. These stands were regenerated naturally, but some have been managed. One to three angle-count sample plots were placed systematically in each stand using a 1 m2 ha-1 basal-area factor. The models can be applied in two settings: tree diameters are either measured or not. The prediction of branch height characteristics, especially height to the lowest dead branch, proved problematic due to weak correlations between these characteristics and other tree dimensions. Compared to previous studies it was found that stem-rot was higher in grey alder than in spruce but lower than in white birch.
