Polylepis woodlands are a vital resource for preserving biodiversity and hydrological functions, which will be altered by climate change and challenge the sustainability of local human communities. However, these highaltitude Andean ecosystems are becoming increasingly vulnerable due to anthropogenic pressure including fragmentation, deforestation and the increase in livestock. Predicting the distribution of native woodlands has become increasingly important to counteract the negative effects of climate change through reforestation and conservation. The objective of this study was to develop and analyze the distribution models of two species that form extensive woodlands along the Andes, namely Polylepis sericea and P. weberbaueri. This study utilized the program Maxent, climate and remotely sensed environmental layers at 1 km resolution. The predicted distribution model for P. sericea i...

El actual modelo de crecimiento económico que estimula a los países ricos en recursos a convertirse en proveedores de materias primas para un mercado global en expansión, está afectando gravemente la condición de grandes áreas naturales, tales como la cuenca occidental del Amazonas, una de las regiones con mayor biodiversidad del planeta. El proceso se acelerará a medida que esta región se vuelva más accesible con el desarrollo de la infraestructura de transporte, así como con la extracción de recursos no renovables. Disminuir estas presiones con el fin de salvaguardar la biodiversidad y los servicios ecosistémicos que presta a la humanidad requiere que los procesos de toma de decisiones se basen en datos relevantes y actualizados. En este sentido, se han aprovechado nuevos datos disponibles para varios grupos de especies, sistemas ecológicos acuáticos y terrestres...
