Sažetak
The paper presents results of measuring wood and leaf mass above the ground level of hop hornbeam shrubs (Ostrya carpinifolia Scop.). An important part of the study describes the development of models for quick and reliable estimation of biomass in forest ecosystems.The research was done and samples collected on seaside slopes of Velebit, the area of the Obrovac forestry, on experimental subplots 1 and 2, Jesenice management unit, department 41. Biomass of wood and leaves was measured separately as weight and volume. Independable estimators were the diameter of the sprout, the height of the sprout and the diameter of the crown. The weight of wood and leaves was measured in kg, volume in m3, diameter of the sprout in cm, height of the sprout and crown diameter in m. General linear modelling was used for the development of the model. The volume of wood in shrubs varied from 18.07 to 65.22 m3/ha, the volume of leaves from 5.75 to 13.70 m3/ha. The volume depends on the degradation stage of the shrub, that is the dimensions of the units composing it, their number in the area, entity and the manner of grouping, and the intrinsic value of site. The results show that wood and leaf mass in hop hornbeam shrubs are in particularly strong linear dependence on diameter of the sprout, height of the sprout and crown diameter. Linear regression coefficient between the volume, as well as the weight of the wood and the diameter of the sprout, was 0.920 at 30 cm height above the ground level, and 0.898 between the volume, as well as the weight of the leaves and the crown of the sprout.The biomass above the ground level in hop hornbeam shrubs can at best be estimated by univariate regression analysis on the basis of sprout diameter, although this regression model yields nearly equal results if based on the height of the sprout and the diameter of the crown. Multivariate regression models do not give much better results than the univariate model, especially by the diameter of the sprout as the best independable estimator, where the values are nearly equal.
