Ranger in the Akagera National park. The Akagera National Park covers 1,200km² in eastern Rwanda, against the Tanzanian border. It was founded in 1934 to protect animals and vegetation in three ecoregions: savannah, mountain and swamp. The park is named for the Kagera River which flows along its eastern boundary feeding into several lakes the largest of which is Lake Ihema. The complex system of lakes and linking papyrus swamps makes up over 1/3 of the park and is the largest protected wetland in central Africa.
