In Chile, most protected areas are located in the southern Andes, in mountainous landscapes at mid or high altitudes. Despite the increasing proportion of protected areas, few have detailed inventories of their biodiversity. This information is essential to define threats and develop long-term integrated conservation programs to face the effects of global change. Consequently, the objectives of this study were to (1) describe the richness, conservation status, and species composition of the vascular flora found in Bosque Pehuén Park; and (2) analyze the relationships among altitude, species richness, and growth forms. Bosque Pehuén is one of the largest privately protected areas located within the Araucarias Biosphere Reserve, in southern Chile (39°S). The park is dominated by secondary forests that grew after intensive exploitation in the 1970s, with some remnant old-growth forests. Fifteen regularly distributed plots, 150 m in radius, were sampled. At each plot, all vascular plant species were recorded; 101 species were found, of which 79% are endemic, 10% are introduced, and 13% are currently listed in IUCN conservation categories. The highest richness was concentrated within the plots associated with riparian zones. The total richness tended to decrease with altitude. Epiphytes and climbers were only recorded at lower altitudes, making them the growth forms most influenced by altitude. The background information reported here is essential for effective park management and conservation of the vascular flora species found within this Andean montane forest.
