Identificación de árboles nativos de importancia para la avifauna local y su potencial uso en paisajes ganaderos de Limón Indanza

Abstract

Native trees provide essential habitats for diverse species of flora and fauna; therefore, this study analyzes the interaction between native trees and local avifauna in Limón Indanza canton, Ecuador, with the objective of identifying tree species⁷ of ecological importance and evaluating their potential in cattle ranching landscapes. Surveys were applied to ranchers and local experts to gather information on the most recognized bird and tree species, as well as their ecological interactions. The results show significant local knowledge, although limited in terms of distinguishing between native and exotic species. Key species such as Inga edulis, Psidium guajava and Vismia tomentosa were identified, highlighted by their high frequency of interaction with frugivorous and nectarivorous birds. As for birds, the study population identified 22 species, with Rupicola peruvianus being the most recognized, followed by Penelope montagnii. In addition, a morphological characterization and a viability test of the seeds of these species was carried out, where Psidium guajava presented greater viability followed by Inga edulis, confirming its potential for restoration programs and silvopastoral systems.
