Predicting the above-ground biomass of crimean pine (Pinus nigra) stands in Turkey

Abstract

In this study, biomass equations are presented for crimean pine (Pinus nigra Arnold) stands within the Zonguldak forest region. A total of 44 sample plots, each of 0.04 ha were chosen in order to define the biomass equations of black pine, the most common needle leaved species in Turkey A tree which is the most similar to mean tree according to basal area was cut in each sample area as a sample tree, Various models were tested, utilizing the diameter (d) and the height (h) as independent variables and the most suitable models were determined. Using these models, above-ground biomass amounts can easily be acquired for single trees and stands.
