Vegetation of Gran Canaria changed after the arrival of humans

Thanks to the analysis of fossil pollen and charcoal remains, a team of scientists has been able to reconstruct the evolution of the vegetation from Gran Canaria between 4,500 and 1,500 years ago. The study reveals that the disappearance of forests in some parts of the island is in part due to the rise in fires and the cultivation of cereals. Both factors are closely related to the arrival of the first indigenous people to the island.
