Costruction of biomass tables of scotchpine (Pinus sylvestris L.) in Amasya Forest Regional headquarter (A case study of Kunduz planing unit)

The purpose of this study is to investigate the biomass of scotchpine stands as single tree in Amasya Forest Regional Headquarter. A total of 32 sample areas was choosen and 50 sample trees choosen, one tree from each sample area was examined. Choosen of the sample treess , was taken care of different diameter breast height and tree height classes, live, robust hill, one body and healthy.Sample trees were cut down from 30 cm heigth, the body were measured from the top to the bottom,1.3m,3.3 m form of 2 m diameter sections. Sample disck with 5 cm thickness were taken from the middle of all stem sections. Gren mass of the baranches; live and dead, were taken and recorded. Sample oe stem discks, samples of live branches, samples of twigs and leaves were collected. All samples were brought to the laboratory for later measurements.Contructing single entry tree biomass tables, total nine equations are examined according to 2 performance criteria standart error of the estimate and R square. Comparisons are made to determine which equations provides the best overall fit to a set of validation data for Pinus sylvestris L. The results indicate that the best model chosen from the equations can be used for Vezirköprü region at 0.05 significant level.Single entry stem and all tree biomass, branch and needles biomass and bark biomass table are constructed as explicted form using the regression equations , , respectively.Determined using the equations above ground biomass in the amount of samples were. İn the Single tree, were determined stem biomass varied from 11.48 to 1581.92 kg, branch biomass varied from 2.34 to 347.53, needle biomass varied from 2.81 to 197.08 kg , all tree biomass varied from 12.66 to 1788.05 kg. In hectar, were determined stem biomass varied from 42 to 267 tones, branch biomass varied from 4 to 175 tones, needle biomass varied from 4.4 to 65 tones, all tree biomass varied from 51 to 287 tones.
