Taï National Park in Côte d’Ivoire (Ivory Coast) is one of the last and largest remaining expanses of primary tropical rainforest in West Africa. Located in the country’s southwest, the park covers an area of approximately 3,300 square kilometres and is surrounded by a buffer zone that increases the total area under environmental protection. It has been listed as a UNESCO World Heritage Site since 1982 and was previously designated a Biosphere Reserve in 1977, owing to its ecological significance and high levels of biodiversity.
The park forms the core of the Upper Guinean rainforest ecosystem—a region that historically spanned several West African nations but has been drastically reduced by deforestation, agriculture, and urban expansion. Taï National Park features a humid tropical climate, with annual rainfall typically ranging between 1,700 and 2,000 millimetres and stable temperatures hovering between 24°C and 28°C. This climate supports dense vegetation characterised by massive, towering trees, some reaching heights of over 50 metres.
Historically, the area was designated a nature reserve in the 1930s during the French colonial period, before being officially converted into a national park in 1972 following Côte d’Ivoire’s independence. Its primary purpose was to protect the remaining tropical forest mass in the region from the encroachment of cocoa and coffee cultivation—activities that had driven the country’s economy for decades.
The forest is home to over 1,200 plant species, many of which are endemic—found nowhere else but in this specific geographic region. The vegetation is structured in multiple layers, ranging from towering trees that form the forest canopy down to shrubs, ground-level herbs, and climbing plants that rely on large trees to reach sunlight.
Regarding wildlife, the reserve serves as a vital sanctuary for numerous species of mammals, birds, reptiles, and amphibians. The park hosts 12 primate species, most notably the western chimpanzee (“Pan troglodytes verus”), a critically endangered species. Chimpanzee communities in Taï exhibit scientifically documented behaviours, such as using stone and wooden tools to crack hard-shelled nuts, as well as employing other tools to extract honey or engage in the organised hunting of smaller monkeys. Other species inhabiting the park include the red colobus monkey and De Brazza’s monkey.
The park is home to the pygmy hippopotamus (“Hexaprotodon liberiensis”), representing one of the few remaining wild populations of this creature. Compared to the common hippopotamus, this species is characterised by its smaller size, elusive nature, and solitary lifestyle.
Populations of the African forest elephant (Loxodonta cyclotis) are found in the park, although their numbers have declined sharply due to poaching. The park is also home to various antelope species, such as Jentink’s duiker and Ogilby’s duiker, as well as carnivores like the African leopard.
More than 300 bird species have been recorded in the park—including rare ones like the white-necked picathartes (or white-necked rockfowl)—alongside a wide diversity of forest insects and amphibians that rely on the park’s streams and swamps.
Taï National Park has long attracted the attention of the international scientific community, leading to the establishment of specialised research stations. Studies on chimpanzees, conducted by the Wild Chimpanzee Foundation and other global institutes, have revealed fascinating behavioural and cultural details about these animals—particularly regarding the intergenerational transmission of skills and tool use.
In addition to behavioural studies, scientific research on epidemiology and viral diseases has been conducted in the park. Tests have detected viruses such as Ebola among local mammal populations, making the park a focal point for studying zoonotic disease transmission (the spread of diseases between animals and humans) and the interplay between natural environments and public health.
Despite its legal protection, Taï National Park faces significant pressures and a range of challenges and threats. Hunting for the “bushmeat” trade is the most direct and persistent threat to the park’s mammals. Poachers target large and medium-sized mammals to supply local and regional markets.
The expansion of cocoa, coffee, and palm oil plantations along the park’s borders has encroached upon adjacent areas. Rising global demand for cocoa drives some individuals to trespass into the protected area to establish illegal farms.
Artisanal and illegal gold mining within the park and along its waterways poses a dual threat, causing soil erosion and water contamination with chemicals such as mercury. The park is surrounded by a growing population that relies on natural resources for its livelihood, creating ongoing friction between local residents and park management regarding land and resource use.
The Ivorian Office of Parks and Reserves (OIPR) manages the park in collaboration with international non-governmental organisations and scientific funding institutions. Protection efforts include deploying patrols to combat poaching and illegal mining, as well as modernising monitoring methods through technologies such as GPS, camera traps, and boundary demarcation. Modern management plans also rely on engaging local communities surrounding the park by establishing alternative development projects and encouraging regulated ecotourism, thereby providing sources of income that do not depend on depleting resources within the reserve’s boundaries. Despite these measures, a lack of financial and logistical resources remains an obstacle to consistently covering the park’s vast expanse.
