The hot tropical rainforests along South America's northwestern Pacific coast to where it connects with Central America is one of the most biologically diverse regions in the world. WWF is working to keep it that way.

Running along the entire Colombian Pacific coast, from southwest Panama to northwest Ecuador, the Choco-Darien region is made up of rainforests, mountains and coastal areas.

The Panamanian Darien part represents some of the richest forests of Central America, while the Colombian Choco has some of the highest numbers of endemic plants in South America.

Many unique species are also found here, including jaguars, ocelots, giant anteaters, tapirs and tamarins.

Humpback whales and marine turtles visit the coasts.

Protecting Latin America's rainforests

The major threat to these species and ecosystem is deforestation.

Road building and other development projects have seen about 1/3 of the area cleared or degraded.

WWF is working with local partners, including indigenous communities, throughout the Choco-Darien region on a number of sustainable development and conservation projects, which include supporting community-based forest management and the creation of protected areas.

Shared waters

Colombia and Panama not only share the Choco-Darien rainforests but also their coastal waters.

Each year, from June to November, humpback whales (Megaptera novaeangliae) stop near the Colombian Pacific coast to mate, give birth and feed their calves. During this period, neighbouring coastal communities offer whale-watching activities to tourists - an alternative, sustainable source of revenue.
