Site characteristics

Arly National Park is a national park located in Tapoa Province, southeastern Burkina Faso. It adjoins Benin's Pendjari National Park in the south and the Singou Reserve in the west. The park is 760 km2 large and has a wide variety of habitats, ranging from the gallery forests of the Arly and Pendjari rivers to savanna woodland and sandstone hills of the Gobnangou chain. It is home to around 200 African elephants (Loxodonta africana), 200 hippopotamus (Hippopotamus amphibius) and 100 lions (Panthera leo). There are also buffaloes, baboons (Papio sp.), green monkeys (Chlorocebus sabaeus), warthogs, and various antelopes, such as the western hartebeest (Alcelaphus buselaphus) and roan antelope (Hippotragus equinus). There are also bushbucks (Tragelaphus scriptus), duikers and waterbuck (Kobus ellipsiprymnus, Manson & Knight 2006).
