Presencia del oso andino Tremarctos ornatus (Carnivora: Ursidae) en el Corredor de Conservación Vilcabamba–Amboró, sureste del Perú

A comprehensive study reveals the presence of the Andean bear (Tremarctos ornatus) across multiple regions and protected areas within the Peruvian sector of the Vilcabamba-Amboro Conservation Corridor, including UNESCO's Historic Sanctuary of Machu Picchu. The research, combining in situ evaluations, interviews, literature reviews, and museum/zoo databases, identified the bear's range from tropical rainforests to highlands (400–4,170 masl) and highlighted critical areas such as Megantoni National Sanctuary, Manu, Amarakaeri, and Japu Bosque-Ukumari Llaqta Private Conservation Areas for their diverse resources. The study suggests potential connectivity between Peruvian and Bolivian bear populations due to proximity to Madidi National Park (Bolivia). However, human activities like agriculture, logging, mining, and infrastructure development pose significant threats by reducing habitat availability, impacting food, refuge, and movement corridors essential for bear population maintenance.
