Parco Nazionale Los Alerces (sito naturale): i giganti millenari della Patagonia

Sulle Ande della Patagonia argentina, fra laghi smeraldo e montagne innevate, sopravvivono foreste antichissime dominate dall’alerce: il larice della Patagonia, un albero che può vivere oltre tremila anni ed è fra i più longevi del pianeta. Los Alerces protegge questi giganti e i paesaggi glaciali che li circondano.

At a glance

Los Alerces National Park, in the Andes of Patagonian Argentina, protects some of the last great stands of the Andean-Patagonian forest, dominated by the alerce (Fitzroya cupressoides) — a giant conifer that can live for more than three thousand years, among the longest-lived trees on Earth. Shaped by ice ages, the park is a landscape of glacial lakes, rivers, moraines and snow-capped peaks, sheltering ancient forest little changed since the retreat of the glaciers. It was inscribed by UNESCO in 2017.

Key facts

  • UNESCO: World Heritage since 2017 (Los Alerces National Park)
  • The alerce: a giant conifer that can live over 3,000 years
  • Ancient forest: some of the last great Andean-Patagonian woodland
  • Glacial landscape: lakes, rivers, moraines and peaks
  • Long-lived trees: among the oldest living things on Earth
  • Patagonian Andes: on the Chile–Argentina mountain border

History

The forests of Los Alerces are survivors: as the great glaciers of the ice ages retreated, the Andean-Patagonian forest spread back across the valleys, and in this protected corner it has remained largely intact. At its heart stand the alerces, slow-growing conifers whose largest specimens, some over 2,000 or even 3,000 years old and 60 m tall, were already ancient when much of human history unfolded.

Heavily logged elsewhere for its durable timber, the alerce found refuge here, and the park was created to protect both the trees and the glacial lakes and mountains around them. Recognised for this near-pristine forest and its venerable trees, Los Alerces was inscribed by UNESCO in 2017.

What you see

Boat trips and trails lead across and around the park’s emerald lakes — Futalaufquen, Menéndez and others — to groves of giant alerces, including the famous “Grandfather” tree, and to viewpoints of forested slopes beneath snow peaks. The clear rivers and lakes, ringed by ancient forest, are the setting throughout.

The serenity of the green lakes beneath the Andes, guarded by thousand-year-old trees, is the beauty of Los Alerces.
