Exclusive wallpaper for WWF members

To mark World Pantanal Day, we’re celebrating the world’s largest tropical wetland and the amazingly diverse wildlife that lives there.

At more than 42 million acres, it sprawls across three South American countries—Bolivia, Brazil and Paraguay.  It's an expansive area of natural beauty, with a mosaic of winding rivers, dense forests, and an abundance of fascinating wildlife.

This beautifully pristine wetland is a refuge for over 4700 species. With capybaras in the dense vegetation around the rivers, caimans lurking in the shallow waters of the marshes and swamps, and the elusive jaguar hunting in the forests, the Pantanal is one of the most biodiverse environments on the planet.

This fascinating biome is also a birdwatcher’s paradise - with a diverse array of species, including the world’s largest parrot, the distinctive cobalt-blue hyacinth macaw, and the vibrant red-and-green macaw.
