Delacour's langur Established in 1962, Cuc Phuong national park is one of Vietnam’s most important protected areas. Though wildlife has suffered a precipitous decline in Vietnam in recent decades, the park’s 222 sq km of primary tropical forest remains home to an amazing variety of animal and plant life: 307 species of bird, 133 species of mammal, 122 species of reptile, 2000 plant species and counting. Even now Cuc Phuong national park has not been fully surveyed but is estimated to contain about three hundred bird species and ninety mammal species, some of which were first discovered in Cuc Phuong, such as red-bellied squirrels and a fish that lives in underground rivers. Several species of bat and monkey, including the critically endangered Delacour’s langur, inhabit the park, while bears and leopards roam its upper reaches. ..817 view More - Vietnam travel photos
