Hydroelectric dams threaten Brazil’s mysterious Pantanal – one of the world’s great wetlands

The Pantanal is the world’s largest tropical wetland and covers an area slightly larger than England. It lies mostly on a huge floodplain at the foot of Brazil’s southwestern highlands, but a fraction also spills over into Bolivia and Paraguay. In the wet season, from October to April, water washes down from those highlands bringing with it nutrients and fish and leaving most of the region underwater. When the rains finish, and the ground dries up, the landscape changes once again. Seasonal variation on such a massive scale means the Pantanal contains a diverse range of plants and animals that have adapted to thrive in standing water or waterlogged soil. The region is home to more than 1,000 bird species and 300 mammals including the jaguar, capybara, giant otter and tapir.
