Critically endangered South American forests thought to be the result of climate change were actually spread by ancient communities, archaeologists have found.

The archaeological analysis began because the experts, from the University of Exeter, University of Reading, University of São Paulo, University of New Mexico, Universidade Federal de Pelotas and Universidade do Sul de Santa Catarina, noticed that in areas of low human activity forests are limited to south-facing slopes, whereas in areas of extensive archaeology, forests cover the entire landscape.

A more rapid and extensive expansion across the whole region later happened between 1,410 and 900 years ago, when forests expanded into highland areas.
