Lake Manyara National Park

Location: Arusha Region Map

Area: 325 km²

 

Lake Manyara National Park, located in northern Tanzania’s Arusha and Manyara regions, is a 330-square-kilometer (127-square-mile) protected area established in 1960. Nestled at the base of the Great Rift Valley’s western escarpment, the park is renowned for its scenic beauty, diverse ecosystems, and iconic wildlife, including tree-climbing lions and vast flamingo flocks. Stretching along the northern shore of Lake Manyara, an alkaline soda lake, the park encompasses groundwater forests, acacia woodlands, wetlands, and hot springs, offering a compact yet rich safari experience. Located 126 km southwest of Arusha, it is a key stop on Tanzania’s northern safari circuit, often paired with visits to Ngorongoro and Serengeti.

 

Geography and Climate

Lake Manyara National Park lies at approximately 3.58°S, 35.83°E, between the alkaline Lake Manyara to the east and the Rift Valley escarpment (rising 600–1,200 meters) to the west. The park’s boundaries cover:

Lake Manyara: A shallow, 231-square-kilometer soda lake (at full extent), though two-thirds lies outside the park. Its size fluctuates seasonally, shrinking to 50–100 km² in the dry season.
Groundwater Forest: A lush, evergreen forest in the north, fed by springs from the escarpment.
Acacia Woodlands: Open savanna and scrub in central and southern areas, transitioning to grasslands near the lake.
Wetlands and Hot Springs: Marshes and geothermal springs (Maji Moto) along the lake’s edge, supporting unique microhabitats.
The park’s elevation ranges from 960 meters (lake level) to 1,600 meters (escarpment slopes), creating varied microclimates. The climate is tropical with distinct seasons:

Temperature: Averages 20–30°C, with highs of 35°C in February and lows of 15°C in July. Nights are cooler at higher elevations.
Rainfall: Annual precipitation is 650–1,200 mm, with a wet season (March–May) and short rains (November–December). The dry season (June–October) is ideal for wildlife viewing.
Humidity: High near the lake and forest (70–90%), lower in savanna areas.

 

Geology

The park’s geology is shaped by the East African Rift System:

Rift Valley Escarpment: Formed 5–7 million years ago as tectonic plates pulled apart, the western escarpment is composed of volcanic rocks (basalt, tuff) and Precambrian gneiss. Faulting created the steep, 600-meter cliffs that frame the park.
Lake Manyara: A rift basin lake, formed by tectonic subsidence, with alkaline sediments rich in sodium carbonate (natron) from volcanic ash. Its shallow depth (1–3 meters) and high salinity result from evaporation and mineral-rich inflows.
Groundwater Springs: Fed by aquifers in the porous volcanic rock of the escarpment, springs like those at Mto wa Mbu sustain the groundwater forest year-round.
Hot Springs (Maji Moto): Geothermal activity, linked to rift volcanism, produces springs with temperatures up to 60°C, notably at the southern end near Endabash.
The park’s soils are diverse: fertile loams in the forest, sandy clays in savannas, and saline mudflats around the lake.

 

Ecology

Lake Manyara National Park’s compact size hosts an astonishing variety of habitats—groundwater forest, acacia woodland, wetlands, and alkaline lake—supporting rich biodiversity.

Flora
The park’s vegetation reflects its varied topography:

Groundwater Forest: A dense, evergreen canopy in the north, dominated by Ficus (fig trees), Trichilia (mahogany), and Croton macrostachyus. Strangler figs and palms (Phoenix reclinata) create a jungle-like atmosphere, with ferns and epiphytes thriving in humid shade.
Acacia Woodlands: Central and southern areas feature Acacia tortilis, Acacia xanthophloea (fever trees), and Balanites aegyptiaca (desert date), mixed with Themeda triandra grasses. Sausage trees (Kigelia africana), with their large, pendulous fruits, are iconic.
Wetlands: Lake margins and rivers (Msasa, Endabash) support reeds (Phragmites), papyrus (Cyperus papyrus), and water lilies, creating marshy habitats.
Scrub and Grasslands: Dry, rocky slopes have Commiphora shrubs and sparse grasses, transitioning to saline-tolerant plants like Suaeda near the lake.

Fauna
The park’s wildlife is diverse, with over 400 species recorded:

Mammals:
Tree-Climbing Lions (Panthera leo): A rare behavior, possibly adapted to escape flies or gain better vantage points, makes Manyara famous. Lions are often seen lounging in acacia trees, especially in the dry season.
Elephants (Loxodonta africana): Large herds roam the forest and savanna, drawn to springs and fruiting trees.
Cape Buffalo (Syncerus caffer): Abundant in wetlands and grasslands, often in herds of 50–200.
Giraffes (Giraffa camelopardalis): Common in acacia woodlands, their long necks visible above the canopy.
Primates: Blue monkeys (Cercopithecus mitis), vervet monkeys (Chlorocebus pygerythrus), and olive baboons (Papio anubis) thrive in forests, with baboons often seen along roads.
Other Mammals: Hippos (Hippopotamus amphibius) wallow in lake shallows, while leopards (Panthera pardus), cheetahs (Acinonyx jubatus), and spotted hyenas (Crocuta crocuta) are less common. Smaller species include bushbuck (Tragelaphus scriptus), impala (Aepyceros melampus), and Kirk’s dik-dik (Madoqua kirkii).
Birds: Over 400 species, making Manyara a birding hotspot. The lake attracts lesser flamingos (Phoeniconaias minor) and greater flamingos (Phoenicopterus roseus), often numbering thousands in the wet season. Other notables include African fish eagles (Haliaeetus vocifer), silvery-cheeked hornbills (Bycanistes brevis), and pelicans (Pelecanus onocrotalus). Wetlands host migratory waders like ruffs (Calidris pugnax) and marsh sandpipers (Tringa stagnatilis), while forests harbor narina trogons (Apaloderma narina).
Reptiles and Amphibians: Nile crocodiles (Crocodylus niloticus) and monitor lizards (Varanus niloticus) inhabit lake edges, with pythons (Python sebae) in forests. Frogs, such as the Hyperolius reed frog, are common in wetlands.
Invertebrates: Butterflies like the African monarch (Danaus chrysippus) and termite mounds are abundant, with dragonflies and beetles in marshes.
The lake’s alkaline waters support phytoplankton, attracting flamingos and fish like tilapia, which sustain birds and crocodiles. The forest’s fruit trees draw primates and elephants, creating a dynamic food web.

 

Cultural and Historical Significance

The park lies within the traditional lands of the Maasai and Iraqw peoples:

Maasai: Semi-nomadic pastoralists graze cattle in areas like the Mto wa Mbu Cultural Corridor, adjacent to the park. Their red shukas and beadwork are visible in nearby markets, and cultural tours showcase their bomas (homesteads), dances, and herding practices.
Iraqw: Bantu-speaking agro-pastoralists cultivate maize, beans, and bananas near the escarpment. Their mud-and-thatch homes and irrigation systems reflect centuries of adaptation.
Historical Context: The area was a hunting ground for local tribes before colonial times. Under German East Africa (1885–1919), the region saw early conservation efforts, continued by the British after 1919. The park was gazetted in 1960 to protect its biodiversity, with expansions in 1974 to include more lakefront.
Cultural Tourism: Mto wa Mbu, a vibrant town 3 km from the park gate, is a melting pot of 120 ethnic groups, offering cultural tours, craft markets, and farm visits. The name “Mto wa Mbu” (“River of Mosquitoes”) reflects the area’s historical insect prevalence, now reduced.
The park inspired Ernest Hemingway’s Green Hills of Africa (1935), based on his 1933 safari, cementing its literary fame. Its role in Tanzania’s northern safari circuit underscores its economic and cultural importance.

Conservation Challenges

Managed by TANAPA, Lake Manyara National Park faces several threats:
Lake Shrinkage: Over-extraction of water for agriculture (e.g., rice fields in Mto wa Mbu) and reduced rainfall have shrunk the lake by up to 50% since the 1960s, threatening flamingos and fish. Dams and irrigation upstream exacerbate this.
Human-Wildlife Conflict: Elephants and baboons raid crops in Mto wa Mbu, leading to poaching or culling risks. TANAPA’s community programs, like chili-fence barriers, deter elephants.
Tourism Pressure: Overcrowding on northern routes risks soil compaction and wildlife stress. Visitor caps and night drive restrictions mitigate impacts.
Invasive Species: Non-native plants like Lantana camara invade woodlands, requiring manual removal. Introduced fish in the lake disrupt native ecosystems.
Climate Change: Warmer temperatures and erratic rains affect lake levels, forest health, and migration patterns. Flamingo breeding is particularly vulnerable.

Conservation efforts include:
Community Engagement: Tourism revenue funds schools, wells, and beekeeping in Mto wa Mbu, reducing reliance on poaching or logging.
Wildlife Monitoring: Rangers track lion and elephant populations, with GPS collars aiding research.
Reforestation: Planting native trees along the escarpment restores degraded areas.
Lake Restoration: Plans to regulate upstream water use aim to stabilize lake levels, supported by UNESCO’s Man and Biosphere program.
