Importancia ecológica y carbono almacenado en biomasa forestal del género Inga en diferentes zonas de vida en Colombia

Abstract

Introduction: The estimation of the diversity, structure and carbon storage of forest species is important for the conservation and sustainable management of tropical forests, it allows to know the degree of vulnerability of the systems, in addition to the function that all fulfill and their possibilities of use. Objective: To estimate the diversity, forest structure and carbon storage of species of the genus Inga in forest inventories, to know the climatic conditions of adaptation and the contribution of the genus in carbon storage. Methods: structural parameters (absolute density, relative density, relative frequency, absolute frequency, relative dominance, importance value index) and diversity indices (Shannon, Pielou and Sorensen) of species of the genus Inga, recorded in forest inventories of 14 zones life of Colombia. Food models were applied in the valuation of forest biomass, the valuation of stored carbon was developed and the Holdridge complexity index was applied. Results: 57 species of the genus were found, in 70.34% of the inventoried plots, in 10 (ten) life zones, only in 4 corresponding to bms-T, Bs-MB, me-ST and Páramo, without individuals of the genus. The most common species were Inga ruiziana 86.21% in Bh-PM, Inga alba 22.86% in Bh-T, Inga sierrae 25% in Bmh-MB, Inga acrocephala 50% in Bmh-PM and Inga pezizifera 50% in Bp-PM. the Shannon-Wiener index (H '), the highest diversity of Inga spices was observed in Bh-PM (5.55), followed by Bh-T (2.95), Bmh-T (1.41), Bp-T (2.59), In the Sorensen index, Inga pezizifera obtained the highest distribution range. It was observed that carbon stored for Inga was 205.4203 C Mg ha-1 year and represented 0.4% of total carbon quantified. Conclusions: An important distribution of the genus was observed, which shows its adaptive potential in different life zones, however, 98% of the species found present a low diversity with fluctuating values between 0.07% and 7.50%.
