Torres Paine: five thousand years of vegetation history

dominated forests up to 570 years before present, declining towards the end of the nineteenth century product of an intense fire.

New palynological reconstruction work summarizes the history of climate and vegetation of the last 5000 years near Torres del Paine (51 ° S). The registration of Moreno and colleagues realize an expansion of forests dominated by Nothofagus from 5 thousand years ago. Forests dominate the landscape until 570 years ago, at which time begins a rapid decline in the late nineteenth century product of an intense fire. The emergence of Rumex acetocella in the latter period documents the invasion of alien species introduced by European settlers. The authors associated vegetation changes, fire occurrence and dynamics of Patagonian glaciers to changes in intensity of westerly winds which are responsible for precipitation and wind speed in the southern hemisphere.
