Descripción
The aim of this work was to quantify the biomass of arboreal species and model the volume of Vernonanthura phosphorica (Vell.) H. in the Arboretum of the Mandonge Forest Station – Manica province. In the study, 4 transects were established and each transect had 3 square plots. The establishment of the plots allowed the identification of individuals, measurement of the diameter of breast height (DBH), total height of tree species and cut of some individuals per species. In the cut of individuals, the components of biomass were separated into stem, branches, leaves and weighed by compartment. For the modeling of the volume of Vernonanthura phosphorica (Vell.) H, the models of Husch, Schumacher-Hall, Meyer and Stoate were considered. According to
the results, the total biomass of tree species was estimated in 23.42 Kg. Among the fifteen species studied, Vernonanthura phosphorica had the highest average of total biomass 3.67 Kg. The best model for estimating the volume of Vernonanthura phosphorica (Vell.) H was the Schumacher-Hall model, as it presents good statistics in relation to the other models.
Keywords: Measurement of tree components, phytomass and volumetric potential.
