Generation of models allometric to determine aerial biomass at the species level, by the destructive method of low intensity for the layer of forest dry Pluviestacional of Ecuador

Abstract

This research was conducted in four different sites in the Dry Forest Pluviestaconal: Mangahurco, Loja; Chacras, El Oro; Mamey, Guayas; and, Piñas del Julcuy, Manabi. A total of four clusters, each with three permanent plots of 60 x 60 m (3600 m2) , where dasometric parameters ( DAP, HT, HT, DC measurement increment borer, pylodin) installed measured, samples were collected floristic to be identified at the Herbarium Loja; ecological parameters were calculated to determine the species to be cleared using the destructive method of low intensity , once cleared was calculated and determined its form factor and biomass expansion factor. 633 individuals of 44 species and 24 families were recorded using botanical taxonomic identification specialists in Dry Forest Herbarium and Loja, 19 species for developing allometric models with the help of the program took InfoStat determining 11 models of statistical summaries highlighting the following: B=β0 +β1 *DAP+β2 *HT; B=β0 +β1 *DAP2 +β2 *HC and B=β0 +β1 *LN DAP+β2 *LN HC (B in kg, DBH in cm, HT and HC in m), considering the following parameters for validation (R2 ≥ 70, AIC, VIF ≤ 10, p-value ≤ 0.05).
