Abstract [es]

La presencia de los seres humanos ha afectado a los bosques de Polylepis desde hace mucho tiempo en los Andes de Ecuador. El objetivo de este estudio es la examinación de la flora de plantas vasculares en los bosques dominados por Polylepis pauta. Especies conocidas de plantas vasculares fueron registradas y especies menos conocidas fueron recolectadas. Todos los datos incluyendo coordenadas y altitud fueron analizados en el Herbario QCA. Se han registrado un total de 104 especies de plantas vasculares, el número de especies recogidas varía entre 16 y 36 en cada estudio local. Principalmente especies andinas dominan los bosques de P. pauta, 75 de las cuales están restringidas a los Andes. Se encontraron un total de 20 especies endémicas del Ecuador. Los bosques de Polylepis son un tipo único de hábitat por lo que vale conservar como un único tipo de hábitat. Polylepis puede contribuir con hábitat y protección para los animales y las plantas, especialmente epífitas. Programas de reforestación con Polylepis podrían ser una buena alternativa para la zona de Oyacachi.

Abstract [en]

Human activity during several thousands of years has considerably changed the forests of Polylepis in the central Andes in Ecuador. The objective of this study was to examine the flora of vascular plants in forest fragments dominated by Polylepis pauta in the Oyacachi area in central Ecuador. Known species of vascular plants were recorded, and species not identified in the field were collected. All data, including coordinates and altitudes, were stored in the QCA Herbarium database. A total of 104 species of vascular plants were recorded. The number of species found varied from 16 to 36 between different localities. The P. Pauta forests are dominated by Andean species, 75 of the recorded species being restricted to the Andes. Of these, 20 are endemic to Ecuador. The Polylepis forest as such is worth conserving as a unique kind of habitat, and can contribute with shelter and protection for many animals and plants, especially epiphytes. Reforestation programs based on Polylepis could be a good alternative in the Oyacachi area.
