The Conquest of the Desert

After Argentina became independent, Patagonia was largely left alone, until it was cleared of Indian occupation in the Conquest of the Desert campaigns of the 1870s.

An attempt was then made to settle the region and to make it part of the national state. However, immigration was not massive, though people did come, for various reasons: some to exploit the economic resources and others (like the Welsh) to enjoy religious or political liberties.

The mineral wealth of the region in particular attracted immigrants from Chile, and Chileans seeking temporary work rather than a fixed domicile now constitute the largest proportion of the population. Apart from major concentrations at Comodoro Rivadavia and in the towns strung out along the upper valley of the Negro River, Patagonia’s sparse population is mostly rural.

Fantastic (and Fantastical) Flora

Patagonia’s vast landscapes vary widely from one end of the region to the other, giving birth to a variety of flora and fauna that at first glance appear to be more fantasy than reality.

Patagonian Steppe (or Desert)

With a precipitation of less than 400 mm (15.7 in) a year, the plants that exist here are limited.

They are primarily low perennial graminoid grasses, bushes and shrubs that can survive the cold winters, the dryness, and the strong winds.

The most common species here are coirón, calafate, mata negra, neneo, mata guanaco, and flowers called paramela, zapatitos de la virgen, and topa topa.

Pre-Andean Shrub and Transition Forest

Increased precipitation towards the west permits the growth of more species and the beginning of forests of scrub and southern beech forests, Nothofagus.

The Nothofagus is of the same family as the beech in the Northern Hemisphere. The southern beeches are from an ancient stock that lived when South America, Australia, New Guinea, New Caledonia, New Zealand and Antarctica were united in a vast continent called Gondwana.

This zone is also home to medium-height shrubs, generally no taller than three feet. Typical vegetation of this area includes: ñire, farolito chino, barba de viejo, pan de indio; the shrubs chaura and siete camisas; and anemonas flowers.

Magellanic Forest

With an average annual rainfall of 800 to 2,000 mm, the lenga forests (another Nothofagus), the world’s southernmost forest, grow beside the glaciers.

The development of these forested areas is limited by two things: the presence of said glacier, and increasing altitude. Over 800 m above sea level, trees become smaller, eventually disappearing once they reach the tree line at 1,200 m (glaciers are 300 m above sea level). In this area, the following would be common: lenga, guindo or coihue de magallanes trees; and the notro bush.
