South Andean Huemul

Fascinating facts about the South Andean Huemul

• Only bucks grow antlers, shedding them each winter, while males have a striking black "face mask" that curves into a heart-shaped pattern around a brown forehead. This sexual dimorphism is notable among deer, aiding population counts that are crucial for a species with fewer than 1,500 individuals left.
• Adult bucks weigh about 90 kg (198 lb) and stand 90 cm tall, while does are 70-80 kg (154-176 lb) and 80 cm high. Their short, stocky build and curled coat hairs protect them from the cold Andes where they live from sea level up to 3,000 m. Such physical resilience lets them survive in the harsh, broken terrain.
• In Argentina the huemul population was estimated at just 350-600 individuals in 2005, fragmented into small groups. This dramatic decline, over 99 % loss from historic numbers, means each surviving animal represents a critical piece of the species' genetic legacy, making every conservation action, from anti-poaching patrols to habitat corridors, a race against extinction.
• A bilateral Memorandum of Understanding signed on 4 December 2010 obliges Argentina and Chile to cooperate on huemul conservation because the deer migrates across their shared border. By sharing data and coordinated action plans, the two nations aim to halt the species' slide toward extinction.
• The National Huemul Corridor project spans more than 2,700 km (1,700 mi) across Patagonia, linking 17 national parks and protecting over 11 million ha (27 million acres). By reconnecting fragmented habitats, the corridor seeks to boost the huemul's dwindling numbers, now less than 1 % of historic levels, while also restoring ecosystems for other iconic species like the Andean condor.

About the South Andean Huemul

Tucked into the glacial valleys and ancient forests of Patagonia, the South Andean huemul is a deer shaped entirely by one of the world's harshest terrains. Stocky, wary, and wrapped in dense hollow fur against the Andean cold, it lives in landscapes so remote that researchers sometimes travel for days to observe a single individual. Chile honours it on its coat of arms while simultaneously struggling to protect the last 1,500 that remain.
