Wildlife of Rwanda

The wildlife of Rwanda comprising its flora and fauna, in prehistoric times, consisted of montane forest in one third the territory of present-day Rwanda. However, natural vegetation is now mostly restricted to the three National Parks and four small forest reserves, with terraced agriculture dominating the rest of the country.[1][2]


Rwanda is a landlocked country in Central Africa, bordered by Burundi, Democratic Republic of the Congo, Tanzania, and Uganda. It measures 26,338 square kilometres (10,169 sq mi) in size, of which 26,668 square kilometres (10,297 sq mi) is land and 1,670 square kilometres (640 sq mi) is water. Its highest point is Volcan Karisimbi at 4,519 metres (14,826 ft), while it lowest point is the Rusizi River at 950 metres (3,120 ft). Rwanda's geography is dominated by savanna grassland with approximately 46 percent considered arable land and 9.5 percent dedicated to permanent crops. Grassy uplands and hills are predominant characteristics of the terrain, while the country's relief is described as mountainous, its altitude demonstrating a decline from the west towards the east.[3]

A unique feature in the geography and geology of Rwanda is Africa’s Great Rift Valley. As part of this rift, Albertine Rift passes through the Nyungwe forest. It is a mountainous feature that "as a whole, harbors more endemic birds, mammals, and amphibians than any other region in Africa".[4]

A rift valley is defined as: "A rift is where sections of the earth are slowly spreading apart over millions of years, creating mountains, lakes, valleys and volcanoes." Another feature is the Congo-Nile Divide. This mountain range passes through Rwanda in a north to south direction.[4]

Nyabarongo River is a major river in Rwanda, part of the upper headwaters of the Nile and accounts for nearly 66% of the water resources of the country fed by a catchment which receives an annual average rainfall of more than 2000 mm.[4]

The country has a temperate climate with rainy seasons twice per year, February to April and again November to January. Temperatures in the mountains are mild, though there is the possibility of frost and snow.[3]

Protected areas

There are only three protected areas established as national parks. The Akagera National Park covers an area of 108,500 ha, Nyungwe National Park has an area of 101,900 ha and Volcanoes National Park has an area of 16,000 ha. In addition the forest reserves are the Gishwati Forest Reserve (700 ha), Mukura Forest Reserve (1600 ha), Busaga Forest Reserve (150 ha) and Buhanga forest and gallery forest in the eastern province of about 160 ha.[2]

Nyungwe is the largest remaining tract of forest which contains 200 species of tree as well as orchids and begonias.[5] Vegetation in the Volcanoes National Park is mostly bamboo and moorland, with small areas of forest.[1] By contrast, Akagera has a savanna ecosystem in which acacia dominates the flora. There are several rare or endangered plant species in Akagera, including Markhamia lutea and Eulophia guineensis.[2]


Nymphaea thermarum is endemic to Rwanda.

The forest cover in Rwanda as of 2007 accounted for 240,746.53 ha comprising humid natural forests in 33.15% area, degraded natural forests covering 15.79%, bamboo forest of 1.82%, savanahs accounting for 1.55%, large eucalyptus plantations to the extent of 26.4%, recent plantations of eucalyptus and coppices and 5.01 percent of pinus plantations.[2] Montane forest, one of the most ancient forests dated to even before the Ice Age which has a unique richness of 200 species of trees, many flowering plants including the giant lobelia and many colourful orchids.[6] There are more than 140 species of orchids in the wildlife area of Nyungwe forest.[7]

There are four defined forest categories. These are: he Congo Nile Ridge Forest, a natural forest that encompasses the national parks and reserves; the savannah and gallery-forests; forest plantations consisting of species of Eucalyptus sp, Pinus sp, and Grevillea robusta; and agroforestry areas in farm lands and also anti-erosion measures.[2]

The world's smallest water lilly, Nymphaea thermarum, was endemic not only to Rwanda, but to the damp mud formed by the overflow of a freshwater hot spring in Mashyuza.[8] It became extinct in the wild about 2008 when local farmers began using the spring for agriculture. The farmers cut off the flow of the spring, which dried up the tiny area—just a few square meters—that was the lily's entire habitat.[8] Carlos Magdalena, at the Royal Botanic Gardens in Kew, managed to germinate some of the last 20 seeds; eight began to flourish and mature within weeks and in November 2009, the waterlilies flowered for the first time.[9]


The greatest diversity of large mammals is found in the three National Parks, which are designated conservation areas.[10] Akagera contains typical savanna animals such as giraffes and elephants,[11] while Volcanoes is home to an estimated one third of the worldwide mountain gorilla population.[12][13]

Nyungwe Forest boasts thirteen primate species including chimpanzees and Ruwenzori colobus arboreal monkeys; the Ruwenzori colobus move in groups of up to 400 individuals, the largest troop size of any primate in Africa.[14] Twenty species of mammals reported by Animal Diversity web of the Museum of Geology University of Michigan are as under.[15]

Primates are the dominant species of fauna in the Nyungwe Forest. The species reported are Ruwenzori colobus, L’Hoest’s monkeys and chimpanzees (largest concentration of 13 species).[4] An amphibian species reported is Hyperolius viridiflavus.[15]

Eastern Rwanda, by contrast, features savanna birds such as the [19] Balaeniceps rex (shoebill) and Agapornis fischeri (Fischer's lovebird) are also reported.[15]

The list of globally endangered species of avi fauna, as reported by the Avibase data of International Bird Life Organization are the following.[24]



The national parks and forest reserves are under threat due to poaching, invasive plants such as water hyacinth, unauthorized livestock grazing, illegal fishing, bush fires, mining, bamboo harvesting, encroachment of protected land for agricultural farming, firewood gathering, be keeping and herbal plant extraction. The resins for such a situation is attributed to governance issues lacking in legal acts and guidelines and also heavy anthropogenic pressure.[2]

Conservation management plans have been instituted for all protected areas which involves the community of villages living in and around the protected areas. Conservation activities have focused on increasing the forest density by planting trees in a "natural self rehabilitation and natural regeneration of primary and high value species". The planting has involved species such as carissa macrocarpa, entandrophragma (a genus of eleven species of deciduous trees) and symphonia globulifera, and erecting protective fencing on the boundary of the forest reserves using leguminous thorny plants.[2]

One of the concerted efforts initiated by the Government of Rwanda is to increase the number of protected areas and to proliferate tree plantations to increase the present forest area cover of 10% to 20% by 2020.[2]
