Estimation of biomass amounts of commercial and non- commercial parts of Red pine, Scots pine and Black pine

This study was realised in the same areas with former studies done by Ünsal (2007) for Red Pine, Atmaca (2008) for Scots Pine and Çakıl (2008) for Black Pine. The aim of the study is to construct useful biomass models including commercial and non-commercial parts. Sample selection of study areas in order to increase the success and efficiency of the ecological, econımic and technical possibilities, taking into account the areas of earlier studies of biomass was adopted and the individuals selected diameter clases distributed. Fort this, first live, topping a solid, single bodied, healthy, breast height diameter trees, with special attention to be caple of (d1.30) were determined. In field study, single trees were sampled and trees were scattered into diameter classes. Totally 40 sample trees were determined and cut from diameter classes, 10-20 cm, 21-40 cm, 31-40 cm and >41 cm (10 trees from each class. First diameter at breast height of all sample trees were measured. After cut, heights of all trees were measured and branches were cut and divided into categories according to commercial (?4 cm) and non commercial (<4 cm) parts and weighed. (?4 cm) and non commercial (<4 cm) parts and weighed Wood with bark samples were taken from woody parts of branches. Then barks were peeled and wood and barks fresh weights determined. In addition needle samples were taken. Stems were divided into sections, weighed, bark and wood samples were taken. Barks of all sample disks and branch parts were shucked and fresh weights wooden parts and barks were measured. Additionally, fresh weights of needle were measured. All samples were dried at oven and oven-dry weights were determined in laboratory. To construct single entry biomass tables, best models were determined represent diameter-weight relationships of components. To construct double entry biomass tables, best models were determined represent diameter and tree height and weight relationships of components.Key Words: Biomass, Red pine, Scots pine, Black pine
