Cambodiahas a wide variety of plants and animals. There are 212 mammal species, 536 bird species, 240 reptile species, 850 freshwater fish species (Tonle Sap Lake area), and 435 marine fish species.
The country has one of the highest deforestation rates in the world. Since 1970, Cambodia's primary rainforest cover fell dramatically from over 70 percent in 1970 to just 3.1 percent in 2007. In total, Cambodia lost 25,000square kilometres (9,700sqmi) of forest between 1990 and 2005—3,340km2(1,290sqmi) of which was primary forest. As of 2007, less than 3,220km2(1,243sqmi) of primary forest remain with the result that the future sustainability of the forest reserves of Cambodia is under severe threat, with illegal loggers looking to generate revenue.
