Summary: | 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 ,
Nectandra reticulata , Otoba parvifolia , Vochysia paraensis , Ficus
sp and Elaeagia obovata stored 51% (81 t C ha-1) of carbon total
estimated
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 , Nectandra
reticulata , Otoba parvifolia , Vochysia paraensis , Ficus sp. y
Elaeagia obovata almacenan el 51% (81 t C ha-1) del carbono total
estimado. |
