Arusha National Park

Arusha National Park

Location: Arusha Region Map

Area: 137 km²

 

Arusha National Park, located in northern Tanzania near the city of Arusha, is a compact yet remarkably diverse 137-square-kilometer (53-square-mile) protected area established in 1960. Nestled between the peaks of Mount Meru and Mount Kilimanjaro, the park is often overshadowed by larger Tanzanian parks like Serengeti or Ngorongoro but offers a unique blend of lush forests, volcanic landscapes, wetlands, and rich wildlife. Its proximity to Arusha city (25 km) and Kilimanjaro International Airport (35 km) makes it an accessible gem for safaris, hiking, and cultural experiences.

 

Geography and Climate

Arusha National Park lies at coordinates approximately 3.25°S, 36.85°E, in Tanzania’s Arusha Region. It spans elevations from 1,400 to 4,566 meters (the summit of Mount Meru), creating a range of habitats within a small area. The park is divided into three distinct zones:

Mount Meru: The park’s centerpiece, a dormant stratovolcano rising to 4,566 meters, is Tanzania’s second-highest peak. Its eastern slopes and crater dominate the western half of the park.
Ngurdoto Crater: A 3-km-wide volcanic caldera in the southeast, often called “Little Ngorongoro,” with a swampy floor and forested rim, inaccessible to vehicles but viewable from lookouts.
Momella Lakes: A series of seven alkaline lakes in the northeast, fed by underground streams, surrounded by grasslands and acacia woodlands.

The park’s climate is tropical with montane influences:
Temperature: Ranges from 15–25°C at lower elevations to near-freezing at Meru’s summit. Daytime temperatures average 20–25°C, with cooler nights.
Rainfall: Annual precipitation varies from 800 mm in lowlands to 2,000 mm on Meru’s slopes. The wet season (March–May) brings heavy rains, while short rains occur in November–December. The dry season (June–October) is ideal for visiting.
Humidity: High in forested areas and around lakes, especially during rainy seasons.

 

Geology

Arusha National Park’s geology is shaped by volcanic activity:
Mount Meru: Formed 1.5 million years ago, Meru is a stratovolcano with a collapsed eastern caldera from a massive eruption 8,000 years ago, scattering ash as far as Kilimanjaro. Its slopes are composed of lava flows, pyroclastic rocks, and ash deposits. The 1910 eruption was the last significant activity, though minor seismic events occur.
Ngurdoto Crater: A smaller caldera formed by volcanic collapse, its steep walls (up to 400 meters) and swampy floor result from ancient eruptions and sediment accumulation.
Momella Lakes: These shallow, alkaline lakes occupy depressions from volcanic activity, with high soda content due to mineral-rich groundwater.
The park’s soils are fertile, supporting dense forests on Meru’s slopes and grasslands in lower areas. Basalt and tuff dominate the bedrock, with loamy soils in wetlands.

 

Ecology

Arusha National Park’s small size belies its ecological diversity, hosting montane forests, savannas, wetlands, and alpine zones.

Flora
The park’s vegetation varies by elevation:
Montane Forest: Covers Meru’s lower slopes (1,500–2,500 m), with dense stands of Podocarpus (yellowwood), Juniperus (cedar), and Hagenia abyssinica. Orchids, ferns, and epiphytes thrive in humid areas, with strangler figs creating dramatic tree formations.
Acacia Woodlands: Surround Momella Lakes and Ngurdoto Crater, dominated by Acacia tortilis and Acacia xanthophloea (fever trees), mixed with grasses like Themeda triandra.
Grasslands: Open savanna areas support grazing herbivores, with Cynodon grasses and wildflowers blooming in the wet season.
Alpine and Heath Zones: Above 2,500 m on Meru, heather (Erica arborea), tussock grasses, and giant lobelias (Lobelia deckenii) dominate, transitioning to barren volcanic rock near the summit.
Wetlands: Ngurdoto’s crater floor and lake margins feature reeds (Phragmites), sedges, and water lilies, supporting aquatic ecosystems.

Fauna
The park’s wildlife, while less dense than Serengeti, is diverse and accessible:

Mammals: Notable species include giraffes (Giraffa camelopardalis), Cape buffalo (Syncerus caffer), and blue monkeys (Cercopithecus mitis). Colobus monkeys (Colobus guereza), with striking black-and-white fur, are common in forests. Smaller mammals like bushbuck (Tragelaphus scriptus), dik-dik (Madoqua kirkii), and warthogs (Phacochoerus africanus) roam savannas. Leopards (Panthera pardus) and hyenas (Crocuta crocuta) are present but elusive. Elephants and lions are absent, making the park safer for walking safaris.
Birds: Over 400 species, including flamingos (Phoenicopterus roseus) on Momella Lakes, African fish eagles (Haliaeetus vocifer), and Narina trogons (Apaloderma narina) in forests. Ngurdoto Crater attracts waterbirds like egrets and herons, while Meru’s slopes host mountain buzzards (Buteo oreophilus).
Reptiles and Amphibians: Pythons (Python sebae), agama lizards (Agama sinaita), and chameleons inhabit forests. Frogs, such as the Hyperolius reed frog, thrive in wetlands.
Invertebrates: Butterflies like the African monarch (Danaus chrysippus) and beetles are abundant, with termite mounds dotting savannas.
The park’s lakes and wetlands are critical for migratory birds, while Meru’s forests provide refuge for primates and rare species.

 

Cultural and Historical Significance

Arusha National Park lies within the traditional lands of the Meru and Maasai peoples:

Meru People: The WaMeru, Bantu-speaking farmers, live around the park’s edges, cultivating bananas, coffee, and maize. Mount Meru is sacred, believed to be a dwelling place of ancestors. The park’s name reflects their cultural presence.
Maasai: Semi-nomadic pastoralists graze cattle near the park, occasionally entering buffer zones. Their colorful beadwork and traditions are visible in nearby villages.
Colonial History: The area was part of German East Africa until 1919, then British Tanganyika. The park was initially a game reserve in the early 20th century, named Ngurdoto Crater National Park in 1960, and renamed Arusha National Park in 1967 to reflect its broader scope and proximity to Arusha city.
Conservation Legacy: The park’s creation involved relocating some Meru communities, leading to ongoing efforts to balance conservation with local livelihoods. Eco-tourism now supports schools and clinics in nearby villages.

 

Visitor Experience

Arusha National Park is a versatile destination, offering safaris, hiking, canoeing, and cultural interactions, often as a day trip or prelude to larger Tanzanian safaris.

Conservation Challenges

Managed by Tanzania National Parks (TANAPA), Arusha National Park faces several threats:

Human-Wildlife Conflict: Nearby Meru and Maasai communities face crop damage from buffalo and monkeys, leading to poaching or retaliation. TANAPA’s community programs, like beekeeping and eco-tourism, aim to reduce conflict.
Deforestation: Historical logging on Meru’s slopes reduced forest cover, though reforestation efforts are ongoing. Illegal charcoal production persists outside park boundaries.
Tourism Pressure: Overuse of trails, especially near Momella Lakes, causes erosion. Canoeing and walking safaris are capped to minimize disturbance.
Invasive Species: Non-native plants like Lantana camara threaten grasslands. TANAPA conducts removal campaigns.
Climate Change: Altered rainfall patterns affect lake levels and forest health, while glacial retreat on Meru’s summit (though minimal) mirrors Kilimanjaro’s ice loss.
Conservation initiatives include ranger patrols, community education, and tourism revenue sharing, which funds schools and water projects. The park’s role in the Arusha Manifesto (1961), Tanzania’s foundational conservation policy, underscores its legacy.

 

Scientific and Cultural Significance
