Índices de biodiversidad florística en 15 fincas en el municipio de La Playa de Belén, Norte de Santander

Abstract

Introduction: Floristic biodiversity is part of the biological wealth of a geographic area.

Objective: Evaluate the floristic biodiversity indices of 15 properties located in the municipality of La Playa de Belén, Norte de Santander through the following variables: richness, diversity, abundance and diversity.

Method: The present study was developed in 15 farms in the municipality of La Playa de Belén in the Norte de Santander department, where three agroecological models were established and the floristic biodiversity indices of abundance, equity, richness, diversity and dominance were assessed.

Results:  54 species belonging to 42 genera and 32 botanical families were found, where the Faboceae and Melastomataceae stand out. The global biodiversity indices of the municipality were: abundance 523, Shannon - Wiener equity 3.47, Specific Wealth 22, Margalef Species Diversity 3.35 and Simpson Dominance 0.040.

Conclusions: The studied areas present 54 species that are distributed in 22 families, which are divided into thickets, shrubs and trees, present in the pre-montane dry forest, which over the years has been divided and limited to small groves, where they predominate low and medium height woody species, as well as species introduced by farmers for their benefit; the bushes are limited to a small number of the species found, but they come to occupy large areas thanks to the ease of their dispersal.
