Terrain forms, bedrock and climate
The nature of the country is determined entirely by its geographical location in the western branch of the East African burial zone. The land surface is thus an elevated horst plateau on the eastern side of the Tanganyika tomb, sloping to the east and southeast from 2,000 to 1,500 m above sea level. The plateau holds, among other things. Ruvubus river basin to the east and Ruzizis to the west. According to COUNTRYAAH, the latter river forms part of Burundi’s west border with Congo (Kinshasa) and joins Lake Kivus with Lake Tanganyika. Between the two rivers runs the water divider, which separates the respective water systems of the Nile and the Congo, reaching a maximum height of 2,670 m above sea level. Most of the country has Precambrian bedrock, which is, however, geologically active, which appears in the form of mainly earthquakes.
Burundi is located in the tropical climate zone, but the temperature conditions are moderated by altitude. The average annual temperature throughout the country is 21 °C; in different areas it varies between 6 °C and 33 °C. The rainfall is on average 1,400 mm per year, but is less than 1000 mm per year in the southwest at Lake Tanganyika.
Plant-and animal life
Practically nothing remains of the lush deciduous forests and tree habitats that originally covered the land. Most of the land is currently cultivated or consists of pasture land, which is why the fauna and flora are severely depleted.
However, some minor remains of the tree saw and a more widespread man-made, more open savannah type harbor some animals, although it is mostly overworked by tambourines. These include antelopes such as impala, topi and oribi, African buffalo, jackals, hyenas, lions, leopards and occasional elephants. In rivers and at The beaches of Tanganyika Lake are found on hippos and occasional crocodiles. Due to the high age of Lake Tanganyika, a unique, rich fauna of fish and invertebrates has been developed there.
Among the birds in Burundi are vultures, fun eagles, southern cranes, egrets, pigeons, shining stars, weavers and sunbirds.
Burundi had three national parks in 2010: Kibira. chimpanzee, Ruvubu and Rusizi (managed as a nature reserve) and eight larger nature reserves. Most forests have some form of protection.
