GARCIA-QUINTANA, Yudel et al. Aerial biomass of botanical families in piedmont evergreen forest subject to intervention levels. Colomb. for. [online]. 2021, vol.24, n.1, pp.45-59.  Epub 28-Abr-2021. ISSN 0120-0739.  https://doi.org/10.14483/2256201x.15939.

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. Detrended correspondence analysis (DCA) indicated variation in the contribution of biomass for each site, having a small number of families to maintain carbon stocks. This provides relevant information that facilitates decision making for restoration in disturbed sites.
