Análisis de la diversidad de avifauna asociada a un sistema agroforestal de café en la microcuenca El Cristal, parroquia Malacatos, Loja

Abstract

The cultivation of shade-grown coffee is a production system of high importance for the conservation of biological diversity. The present study allowed to determine the composition of the avifauna present in the agroforestry systems of coffee and grassland of the micro watershed of the El Cristal river. Between April and May of 2017, the local bird species richness was evaluated through three methods: fog net capture, visual and audio encounter surveys. The used diversity indices suggest that the site has a high diversity according to Simpson (0.86) and average diversity according to Shannon (2.66). Of the total number of recorded species (30) six are endemic, three are migratory and neither one is threatened. Only 11 species were recorded in the pasture, whereas in the coffee plantation from the 26 recorded species, 60% were insectivores and 60% had low sensitivity. The bird species from the coffee plantation used the site as a feeding nesting zone, among other uses. Wooded coffee plantations are key elements of the landscape, maintaining relatively similar conditions to the original ecosystem.
