Covering a region of 140,000 sq. km, the Pantanal is world''s largest wetland. Greece for example measures 132,000 sq. km. During the rainy season, the Paraguay River and its tributaries inundate large areas. In the dry season the region turns into a savannah shimmering with heat. Green vegetation then can be found only in lake regions and river plains.
The great variety of large species is immense and comparable to that in Africa. Among them are the Spectacled Caiman, the Yellow Anaconda, the Plains Tapir, Jaguar, Rheas, White-necked Heron, Jabiru as well as huge flocks of waders and waterfowl from North America that winter in the Pantanal wetlands.
