Caracterización florística, estructural, diversidad, dinámica y ordenación de la vegetación en cuatro veredas de Guaduas, Cundinamarca

Abstract

The vegetation was characterized in four sidewalks of Guaduas, Cundinamarca, through a preferential sampling of twenty - five surveys of 1000 m2 of surface each. The structure, richness and diversity, dynamics, and classification and ordering of the floristic component were evaluated through the methodology proposed by Cantillo (2007) and Cantillo and Rangel (2011), where there are three phases: preparation, field and analysis of data . Six syntaxonomic units, two alliances, three associations and one community were determined. The species with higher IVI, IPF, sociological position and IVIA were Cyathea caracasana, Quercus humboldtii and Croton gossypiifolius, where the arboreal stratum is inferior to the more dominant stratum and the subarbóreo has the greatest wealth and diversity; In addition, 1684 individuals, 187 species, 117 genera and 57 families were registered, being an area with low middle heterogeneity, high diversity, equity and low dominance. The dynamics show predominance of heliophite guilds and an initial to intermediate successional state, in the process of transition to larger size classes. When ordering vegetation according to soil factors, C.E.C and CO% have the greatest influence on the plant component.
