The Pantanal, Brazil

 

Brazil's Pantanal is the principal component of one of the world's largest freshwater wetlands systems. While the entire Pantanal region extends into the neighboring countries of Bolivia and Paraguay, approximately 80% of the area is in Brazil. Located on the country's western side near Bolivia and Paraguay, Brazil's Pantanal is an immense alluvial plain, spanning 140,000 square kilometers throughout the states of Mato Grosso and Mato Grosso do Sul. Its landscape encompasses a variety of ecological sub-regions, including river corridors, gallery forests, perennial wetlands and lakes, seasonally inundated grasslands, and terrestrial forests. Together, these natural tracts form one of the greatest and most biologically diverse ecosystems on the planet.       

 

  Each year, heavy tropical rains cause the main tributaries supplying the Pantanal's waters to overflow, flooding an area approximately the size of the state of Colorado. During the dry season, the floodwaters recede, resulting in a rich and complex mosaic of grasslands and forests, dotted with countless lagoons and marshes. This annual cycle makes the Pantanal one of the world's most productive wildlife habitats. Millions of waterfowl breed and feed along its rivers and lagoons, and dense populations of jaguars, capybaras, marsh deer, giant anteaters, tapirs, hyacinth macaws, and others thrive in its forests and grasslands. The waters themselves are home to vast numbers of caiman, giant otters, and a large, diverse group of fish species estimated to number at least 260. More than 650 species of birds have also been identified, as many species in the United States and Canada combined.
