The Los Alerces National Park is experiencing an atypical winter. The lack of snow, unusual for this time of year in the mountainous region of Chubut, has raised alarm signals among those responsible for the protected area. Although this situation facilitates internal transit and operational tasks, it poses serious ecological challenges.
Currently, internal roads such as Provincial Route 71 and access to Puerto Limonao remain clear, allowing the arrival of tourists and normal maintenance. However, the low level of snowfall anticipates a summer with extreme drought conditions.
This scenario puts the integrity of the ecosystem at risk, as it increases the probability of forest fires. In response, park authorities have begun updating their fire management plan and have reinforced training on fire propagation factors and behavior in natural environments.

Surveillance and Limited Resources in the Face of a Critical Summer
Park technical staff participate in specialized workshops on the severity of fires and study variables such as accumulation of combustible material, soil moisture, and wind speed. Anticipation is key to reducing risks, although structural limitations persist.
Despite recent additions to the park ranger corps, the personnel deficit continues to affect operability, especially in the administrative area. The management of procedures and bureaucratic processes slows down, just as the high season begins to demand more activity.
In this context, the park aims to add firefighters and operational personnel, as has occurred in previous years. The strategy includes increased preventive presence in risk areas, satellite monitoring, and active patrols to detect fire outbreaks in time.
A Natural Sanctuary Under Environmental Pressure
The Los Alerces National Park is one of the most valuable natural reserves in Patagonia. Declared a World Heritage Site by UNESCO, it protects extensive native forests and emblematic species such as the larch, one of the longest-lived trees on the planet.
Its geography includes crystalline lakes, pristine rivers, glaciers, and mountains that are part of the Patagonian Andean ecosystem. Among its most outstanding environments are Lake Futalaufquen, the Arrayanes River, and the Torrecillas Glacier, sites that host a unique biodiversity.
The flora is dominated by species such as the Patagonian cypress, the coihue, and the arrayán. In terms of fauna, the huemul, the pudú, the puma, and more than 120 species of birds inhabit the park. The park also plays key roles as a water regulator, genetic reservoir, and carbon sink.

Guarding Biodiversity in the Face of Climate Change
The effects of climate change are already evident in this region. The decrease in snowfall alters hydrological cycles and weakens ecosystems against disturbances such as fires or invasive species. The lack of snow coverage also reduces water supply in summer.
Therefore, the conservation of Los Alerces requires comprehensive planning that considers not only immediate risks such as fire but also long-term actions. It is necessary to strengthen infrastructure, incorporate technology, and ensure trained human resources to face new environmental scenarios.
Meanwhile, the park remains a chosen destination for tourists and a vital refuge for Patagonian nature. However, its ecological balance will increasingly depend on political decisions, public investment, and environmental awareness.
