Estimación de biomasa en plantaciones de teca (Tectona grandis) de la región Costa del Ecuador por medio de ecuaciones alométricas.

Abstract

The environmental situation of the planet is one of the most alarming problems in the current scenario due to the consequences of climate change. Based on the foregoing in this investigation, the biomass present in teak plantations was quantified using allometric equations and remote sensing technology such as the terrestrial laser scanner. The use of non-destructive methods prevented the demolition of trees and the partial destruction of the forest environment. This research is an exploratory type of a non-experimental nature, has a quantitative approach and a descriptive and correlational scope. For the biomass estimation, allometric models were constructed for the calculation of volume by means of the non-linear regression analysis, in turn the density was obtained by the natural drying of stem and branch samples extracted in the field. For the samples of the shaft, pressler bore was used. As research results a specific density value of local teak wood of 500 kgm3 was determined for a three-year plantation and a biomass distribution area with a 67 % spindle accumulation, 24 % on branches and 8 % in sheets. It is recommended in future research to conduct density studies and estimation of biomass in teak to analyze variations.
