Abstract
Se calculó la cantidad de carbono contenida en la biomasa del bosque de
terraza baja en la zona de Loreto en Requena. Se consideraron los datos
del censo forestal de especies comerciales en la parcela de tala de las
concesiones madereras (PC1) del plan operativo (PO1). Se realizaron
estimaciones indirectas de la biomasa seca utilizando la densidad básica y
el volumen comercial. Se contaron en total 927 árboles, que representaban
a cinco familias botánicas y cinco especies forestales comerciales. La
biomasa total estimada fue de 7 499 856,35 kg (14 122,43 kg/ha), mientras
que las reservas de carbono estimadas fueron de 8,47 tC/ha. Maquira
coriaceae (7,91 tC/ha) tenía la mayor reserva de carbono, seguida de
Calycophyllum spruceanum (0,39 tC/ha) y Ceiba pentandra (0,08 tC/ha).
Los almacenes de carbono más bajos se encontraron en Hura crepitans e
Iryanthera elliptica (0,06 tC/ha y 0,04 tC/ha) respectivamente. Las clases
mayores de 110 cm (1,91 tC/ha) presentaron las mayores reservas de
carbono, seguidas de las clases entre 90 y 99 cm (1,49 tC/ha) y las clases
entre 100 y 109 cm (1,41 tC/ha). Según la prueba Chi-cuadrado, el p-valor
del comparador es inferior a (0,009) el nivel de significación de 0,05. Esto
sugiere que, con un umbral de significación de α = 0,05, se acepta la
hipótesis alternativa de que existen diferencias entre las especies forestales
en el bosque de terraza baja en términos de biomasa y carbono
almacenado.
The amount of carbon contained in the biomass of the low terrace forest in the Loreto area of Requena was calculated. Data from the forest census of commercial species in the logging plot of the logging concessions (PC1) of the operational plan (PO1) were considered. Indirect estimates of dry biomass were made using basic density and commercial volume. A total of 927 trees were counted, representing five botanical families and five commercial forest species. Total estimated biomass was 7 499 856,35 kg (14 122,43 kg/ha), while estimated carbon stocks were 8,47 tC/ha. Maquira coriaceae (7,91 tC/ha) had the highest carbon stock, followed by Calycophyllum spruceanum (0,39 tC/ha) and Ceiba pentandra (0,08 tC/ha). The lowest carbon stores were found in Hura crepitans and Iryanthera elliptica (0,06 tC/ha and 0,04 tC/ha) respectively. Classes larger than 110 cm (1,91 tC/ha) had the highest carbon stocks, followed by classes between 90 and 99 cm (1,49 tC/ha) and classes between 100 and 109 cm (1,41 tC/ha). According to the Chi-square test, the p-value of the comparator is less than (0,009) the significance level of 0,05. This suggests that, with a significance threshold of α = 0,05, the alternative hypothesis that there are differences between forest species in the low terrace forest in terms of biomass and carbon stored is accepted.
