 en ALLOMETRIC MODELS TO ESTIMATE STOCKS CARBON IN THE LOWER MONTANE FORESTS IN SOUTH OF ECUADOR
Sivisaca, Deicy Carolina Lozano; Herrera, Byron Gonzalo Palacios & Mendoza, Zhofre Huberto Aguirre

Abstract

In Ecuador, there are montane forests of great biological importance that provide ecosystem services such as carbon storage. For this reason, we did this research for generate allometric models through by quantifying carbon in lower montane forests. We established one permanent plot of one hectare and measured all the trees with diameter at breast height (DBH1,30m) ≥ 5 cm. The variables that were used to generate the models were: DBH and total height (th). The tree biomass was 322.37 t ha-1 and the estimated total carbon was 161.07 t ha-1. In the allometric models of the arboreal stratum, the variables that were adjusted best were: DBH, DBH2 and th. The botanical family with more biomass (69.95 t ha-1) and carbon (34.98 t C ha-1) was Moraceae, which together with Lauraceae, Rubiaceae and Myristicaceae stored the 57% carbon (91.55 t C ha-1) in the lower montane forest. Of the 179 botanical species registered, Pseudolmedia laevigata check for this species in other resources , Nectandra reticulata check for this species in other resources , Otoba parvifolia check for this species in other resources , Vochysia paraensis check for this species in other resources , Ficus check for this species in other resources sp and Elaeagia obovata check for this species in other resources stored 51% (81 t C ha-1) of carbon total estimated

 es MODELOS ALOMÉTRICOS PARA ESTIMAR EL ALMACENAMIENTO DE CARBONO DE BOSQUES MONTANOS BAJOS EN EL SUR DEL ECUADOR
Sivisaca, Deicy Carolina Lozano; Herrera, Byron Gonzalo Palacios & Mendoza, Zhofre Huberto Aguirre

Resumen

En Ecuador existen bosques montanos bajos de gran importancia biológica que proveen de servicios ecosistémicos como el almacenamiento de carbono. Por esta razón, se desarrolló una investigación que permitió elaborar modelos alométricos mediante la cuantificación de carbono en el bosque montano bajo. Se estableció una parcela permanente de una hectárea y se midieron todos los árboles con diámetro a la altura del pecho (DAP1,30m) ≥ 5 cm. Las variables que se usaron para la generación de los modelos fueron DAP y altura total (ht). La biomasa arbórea fue de 322,37 t ha-1 y el carbono total estimado fue de 161,07 t ha-1. En los modelos alométricos del estrato arbóreo, las variables que mejor se ajustaron fueron DAP, DAP2 y ht. La familia botánica con mayor biomasa (69,95 t ha-1) y carbono (34,98 t C ha-1) fue Moraceae, que conjuntamente con Lauraceae, Myristicaceae y Rubiaceae almacenan el 57% de carbono (91,55 t C ha-1) del bosque montano bajo. De las 179 especies botánicas registradas, las especies Pseudolmedia laevigata check for this species in other resources , Nectandra reticulata check for this species in other resources , Otoba parvifolia check for this species in other resources , Vochysia paraensis check for this species in other resources , Ficus check for this species in other resources sp. y Elaeagia obovata check for this species in other resources almacenan el 51% (81 t C ha-1) del carbono total estimado.
