Monitoreo de plántulas emergentes del banco de semillas germinables (BSG) en áreas fragmentadas de piedemonte vecinas a Villavicencio y su relación con las características físico-químicas del suelo

Abstract

The Piedmont Plains is a strategic ecosystem that provides important ecosystem services, in Villavicencio’s located, which has an area known as the green belt of which it is part of the avant-garde forest reserve, the botanical garden of Villavicencio, Playa Rica and the sector of the residential condominium “Rincon de las Lomas”. Due to urban increase and other anthropogenic activities, it has presented fragmentation problems that compromise the composition and diversity of the seed bank (GSB), in turn, modifying the soil composition. The present study performed an ex-situ monitoring over a period of four months of emerging seedlings from the GSB in three fragmented areas with different size (Fragment N°1: 138,5 ha, fragment N°2: 23,5 ha, fragment N°3: 76,5 ha) and its relation with the physicochemical characteristics of the soil (pH, texture, color, humidity, apparent density and percentage of organic matter). To do this, analyze the 100 meter transects in each of the fragments to study. From which 84 soil samples will be collected in total for vivarium and 42 samples for analysis of physicochemical variables of the soil. A seedling count per species was performed, monitoring its growth, diversity and abundance of emerging seedlings with the physicochemical variables of the soil between the different fragments in order to determine how fragment size influences the piedmont ecosystem. The results of this study are part of the baseline generation for the establishment of ecological restoration protocols for altered areas of piedmont, including the formation of a list of plants with potential for the restoration of these sites.
