Biomasa aérea de familias botánicas en un bosque siempreverde piemontano sometido a grados de intervención

Abstract

The accumulated aerial biomass was evaluated at the level of botanical families in an evergreen montane forest subject to different degrees of intervention in the upper Puyo river watershed. In five transects of 0.1 ha, species with diameter at breast height (DBH) ≥ 10 cm were recorded. Fewer families were found in sites with a high degree of disturbance. The aerial biomass varied from 161.84 to 339.70 Mg.ha-1, with greater accumulation in individuals of smaller diametric class. The families with the highest biomass importance value index were Moraceae, Arecaceae and Euphorbiaceae, recognized for their potential in terms of structure and carbon.

This provides relevant information that facilitates decision making for restoration in disturbed sites.
