Although only a small part of the original forests remains, it is still one of the most diverse ecosystems on the planet, second only to the Amazon
The forest is home to around 20,000 species of plants. Some 450 tree species have been found in just one hectare.
There are also thousands of species of birds, mammals, reptiles and amphibians, including endangered jaguars
, golden lion tamarins
, woolly spider monkeys
, maned three-toed sloths
and red-tailed parrots
Conserving what's left
Very little of the Atlantic Forest remains and what does is highly fragmented.
The forests continue to be vulnerable to logging
and agricultural expansion
, particularly soy production. Habitat loss and hunting put many species in danger of extinction.
WWF is working in Brazil, Paraguay and Argentina to encourage forest conservation
and better management of protected areas
