Models for the estimation of single tree volume in four Miombo woodland types

Single tree volume estimation models are produced for four Julbernardia-Brachystegia woodlands in Malawi. The estimation models are based on the regression of volume on one or a number of independent variables derived from diameter and height. In total, 1282 trees from 46 species were felled and ind...

Description
Summary:Single tree volume estimation models are produced for four Julbernardia-Brachystegia woodlands in Malawi. The estimation models are based on the regression of volume on one or a number of independent variables derived from diameter and height. In total, 1282 trees from 46 species were felled and individually measured. Site-specific models were produced for the dominant species and important species groups, with separate models for canopy and under-storey species groups from three sites. Compared to diameter, height was a poor predictor of volume and only derivations of diameter were used wherever possible. The models may have wider applicability, particularly in woodlands with similar structure, climatic and edaphic conditions, but should be validated since their applicability outside of the four sample sites has not yet been tested.
