Índice de diversidad y dominancia del bosque seco Utmach-Chacras del cantón Arenillas para la clasificación de especies endémicas y etnobotánicas

Abstract

The Ecuadorian dry forests have a great wealth of flora and fauna, unique in the world; At the floristic level, this ecosystem has a great diversity which can only be known through floristic inventories. The following study was carried out in the Chacras’ dry forest, an area that has a high floristic potential for which it was proposed as an objective to calculate the diversity and floristic dominance through the Simpson index, in order to determine those endemic species representatives of the dry forest and at the same time what ethnobotanical uses they have, in order to classify them and then enable their registration and inventory of the most relevant species in the area. To calculate diversity and dominance, it was necessary to use random design methodologies and types of samples by transects, which allowed to obtain a greater scope of the studied area to later be quantified using the Simpson index, which resulted in a high index of diversity and dominance> 0.8, in the same way it was also recorded that 7 of all the identified species turned out to be endemic and only 1 species of the total does not conserve any ethnobotanical use. Having said this, it was concluded that in the area of study, it was possible to define both endemic and ethnobotanical species using the Simpson method as an indicator of diversity.
