Potential of Biomass and Spatial Distribution of Forest Plantation Of Hybrid Eucalyptus

Abstract

The purpose of this research was to estimate and determine the distribution of biomass in the forest of Hybrid Eucalyptus . The allometric equation was then developed based on growth dimension, i.e. the diameter. The research was conducted at the stands in year 0.3 up to 7 and 14 Hybrid Eucalyptus, in Industrial Plantation Forest of PT.Toba Pulp Lestari (PT.TPL) in Aek Nauli District, North Sumatera. The potency of biomass were estimated from direct measurement using destructive technique. Spatial distribution of biomass using geospatial technology. Results showed that hybrid Eucalyptus had an average above-ground biomass are 24,304 tons/ha. Criteria for low biomass , medium and high in each compartmen, resppectively for 0 - 8 t / ha; 9 - 17 t / ha and 18 - 26 t / ha. Criteria for low biomass has the largest persentase is 84.5% and also has the largest area is 1,874, 3 ha. As for the medium and high biomass criteria each have a percentage 12.69% and 2.76% resppectively with an area of 281.3 ha and 61.2 ha.
