By area, Termit and Tin-Toumma is one of the largest protected areas in the world: nearly a hundred thousand square kilometres of desert in south-eastern Niger, more than the whole of Hungary. By what it holds, it is one of the most fragile and important wildlife sanctuaries on the planet. It is the last viable refuge of the addax, a Saharan antelope that can survive without drinking free water. Fewer than a hundred remain in the wild anywhere in the world.
The area combines two landscapes. The Termit massif is a 180-kilometre spine of dark sandstone rising to seven hundred metres. It breaks the monotony of the desert and is where life gathers: the vegetation in its wadis supports the aoudad, the gazelles and the last Saharan cheetahs. Tin-Toumma, to the east, is the opposite: an almost unbroken plain of sand with no relief and no water. That is exactly why it became the last place where the addax could survive, far from hunters.
WARNING OF THE HIGHEST IMPORTANCE: the reserve stretches across the Zinder and Diffa regions, and Diffa is one of the most dangerous areas of Niger because of armed groups operating around Lake Chad. There is no organised tourism, no year-round passable tracks, no settlements and no phone signal. The United States keeps the country at Level 4 “Do Not Travel” and cannot provide consular services outside Niamey. This guide documents what is there and what is at stake. It does not suggest or help with a trip that is neither possible nor sensible today.
People have lived on the Termit massif since the Neolithic, when the Sahara was green and its wadis were corridors of life. Some of the oldest evidence of iron metallurgy in West Africa has been found in the area. When the desert closed in, the massif became a biological refuge: an island of relief and vegetation in the middle of nowhere, with Saharan wildlife that had already disappeared from the rest of the continent. In 1962, just after independence, Niger created a 700,000-hectare wildlife reserve there to protect endangered species. It was not enough. From the 1970s onwards, hunting (including hunting expeditions from Libya and the Gulf), drought and human pressure caused the populations of addax, dama gazelle and cheetah to collapse. After a decade of work by the Sahara Conservation Fund, the IUCN and other organisations, Niger's Council of Ministers decreed the creation of the Termit and Tin-Toumma National Nature Reserve on 6 March 2012. At about 100,000 km², it is one of the largest on the planet. The victory was short-lived. On 26 June 2019, the same Council of Ministers announced plans to remove about 45,000 km² (roughly 45 % of the area) to make way for oil exploration by the China National Petroleum Corporation. Today the NGO Noé manages the reserve on the ground, and wild addax are still counted in the dozens.

Origins, formation and what the sources say.
The Termit Massif is an anomaly in the landscape. In south-eastern Niger, between the Zinder and Diffa regions, a spine of dark sandstone 180 kilometres long and about 40 wide (around 3,500 square kilometres) rises to between 350 and 700 metres above sea level from completely flat surroundings. To the north lies the Ténéré. To the east is the Tin-Toumma desert, a featureless plain of sand and one of the emptiest places in Africa.
That difference of a few hundred metres changes everything. The high ground catches what little moisture there is and produces runoff when it rains. Rainfall is under a hundred millimetres a year, and not every year. The runoff feeds a network of wadis, dry riverbeds where acacias and scrub gather. In a hyper-arid desert, a wadi with plants is an artery: all life passes through it.
The result is a biological refuge. When the Sahara finished drying out, around the third millennium BCE, the savannah wildlife retreated south. The isolated mountains and massifs (the Aïr, the Tibesti, the Hoggar, the Termit) were left as islands where some species could hold on. Termit kept its large Saharan mammals long after they had vanished from the rest of the region.
Tin-Toumma played a different and complementary role. There is no relief there, no wadis, practically nothing. It is a desert of sand so hostile, and so useless for any human activity, that it became the last place where certain species could live without being hunted, simply because nothing else was left. The addax survived in Tin-Toumma because nobody else wanted to go there.
There is also a very old human story here. People lived on the massif from the Neolithic, when the Sahara was green. The Termit area is one of the key sites for studying the beginnings of iron metallurgy in West Africa, with dates among the earliest on the continent. Today's absolute desert was once inhabited, productive land.
Niger became independent from France in 1960. Barely two years later, in 1962, the new state created a 700,000-hectare wildlife reserve on the Termit Massif to protect the area's threatened species. It was a remarkably early decision: at the time, very few people cared about conserving Saharan wildlife.
On paper, the 1962 reserve protected a group of species that was still fairly abundant: herds of addax, dama and dorcas gazelles, Barbary sheep on the massif's escarpments, Saharan cheetahs, fennec foxes and jackals. The area still held a working Saharan ecosystem, with both herbivores and predators.
The problem is that a paper reserve protects nothing in seven hundred thousand hectares with no roads, no patrols and no budget. From the 1970s on, the populations began to collapse because of three factors working together.
The first was hunting. Motor vehicles changed the rules completely. Chase an addax or a dama gazelle with four-wheel drives and modern weapons, and an animal built to outrun predators on foot becomes defenceless prey. On top of local hunting came hunting expeditions from Libya and the Gulf states, which worked the region for decades.
The second was drought. The great Sahel droughts of the 1970s and 1980s cut the available vegetation dramatically. They also pushed nomadic herders north, so more animals competed for the same scarce resources.
The third was general human pressure: more livestock, firewood gathering, new tracks and, later, oil and gas prospecting. By the 2000s the addax was on the verge of disappearing. The Saharan cheetah had become an almost ghostly animal, known more from tracks and camera traps than from sightings.
In the early 2000s, a group of organisations began working steadily with the Nigerien authorities to secure real protection on the right scale. They included the Sahara Conservation Fund, the IUCN, the Convention on Migratory Species and several technical partners. The argument was clear: Saharan species range over enormous distances, and protecting them takes enormous areas.
The work took a decade. On 6 March 2012, the Council of Ministers of the Republic of Niger formally decreed the creation of the Termit and Tin-Toumma National Nature Reserve. It covers nearly 100,000 square kilometres (some 38,600 square miles), an area larger than Hungary and one of the largest land protected areas on the planet. The international press rightly reported it as a desert park bigger than a European country.
The protected area brings together the two complementary environments. One is the Termit Massif, with its relief, its wadis and its vegetation. The other is the Tin-Toumma plain, the absolute void where the addax survives. The reserve has recorded 130 bird species and 17 mammal species. It holds what is considered the largest remaining addax population in the world, plus critical groups of dama gazelle, dorcas gazelle, Saharan cheetah and Barbary sheep.
International recognition had come earlier. In 2006, Niger had put the area forward for the UNESCO World Heritage List for its biodiversity, in a landscape that runs from mountains and valleys to grassy plains, open desert and sand seas.
The Nigerien state took charge of management on the ground, with help from specialist organisations. The French NGO Noé took on running the reserve, supported by the Sahara Conservation Fund and the Zoological Society of London, which runs tracking and monitoring programmes in the area. The tools are the ones a roadless territory of a hundred thousand square kilometres demands: satellite GPS collars, aerial surveys and work with the Toubou, Tuareg and Arab nomadic communities who know the terrain.
The addax (Addax nasomaculatus) is probably the mammal best adapted to extreme desert on the planet. Its very pale coat reflects the sun. Its broad, flat hooves let it walk on soft sand. Its horns form an unmistakable spiral. Its body can live without drinking free water: it gets all the moisture it needs from the plants it eats, and it concentrates its urine as far as possible. It can travel huge distances in search of the grazing that sprouts after a lone shower.
That perfection has a fatal downside. The addax is slow and trusting, built to escape predators on foot in a place where nothing else survives. Against a four-wheel drive it has no chance at all. In practice, it is the easiest antelope in the world to kill.
The result is documented with brutal precision. The IUCN lists the addax as critically endangered. There are fewer than 100 in the wild, and they occupy just 0.68% of the species' historical range, reduced to a single population in the Tin-Toumma desert. In other words, every wild addax on the planet lives inside this reserve.
The surveys say even more. A thorough Sahara Conservation Fund search in 2015 failed to find a single live animal and found tracks and indirect evidence of no more than 25. An aerial survey in March 2016 spotted just three addax in the whole area. Three.
The immediate cause of that final collapse has a name. Studies and reports from conservation organisations point to the expansion of oil operations in south-eastern Niger, mainly those of the China National Petroleum Corporation. Above all, they point to poaching by military personnel hired to protect those operations. It was not the infrastructure itself: it was the weapons and vehicles that came with it.
There is still some hope. Around 1,000 addax live in ex situ populations (zoos, private reserves and breeding centres around the world). They have enough genetic diversity to support reintroduction programmes, like the ones Tunisia has run since the mid-1980s. The species is not doomed. Its original wild population is, if nothing changes.
South-eastern Niger has oil, and oil is the factor that will shape Termit's future. The China National Petroleum Corporation holds exploration rights inside the reserve and has been pushing for years to expand its operations. A decade earlier, Niger had announced a 5 billion dollar investment by the company to develop wells, a 20,000-barrel-a-day refinery and an export pipeline.
The clash came on 26 June 2019. Niger's Council of Ministers announced plans to remove about 45,000 square kilometres from the protected area, around 45% of its total surface, and open them to oil activity. International conservation organisations reacted immediately. They pointed out the contradiction of dismantling almost half of Africa's largest reserve right where the planet's last wild addax population survives.
On top of that came another problem, even harder to manage: security. The reserve stretches across the Zinder and Diffa regions. The Diffa region, around Lake Chad, is one of the most dangerous parts of Niger because of armed groups. Since the mid-2010s it has seen mass displacement and a serious humanitarian crisis. Doing conservation work in territory like that is extremely hard and dangerous.
The coup of 26 July 2023 and the military junta that followed also reshaped the country's foreign alliances and the international funding behind many programmes. The United States keeps the whole of Niger at Level 4 "Do Not Travel", an advisory renewed on 9 July 2026, citing crime, unrest, terrorism, health and kidnapping. It cannot provide consular services outside Niamey, and the authorities require a military escort for any foreigner leaving the capital.
The result is one of the most awkward paradoxes in world conservation. Africa's largest reserve took ten years of diplomatic and technical work to create. On paper, it protects an irreplaceable biological treasure. Yet it is also a place almost nobody can enter, where real patrolling is minimal, and where the extractive industry and armed groups move more freely than the rangers.
And yet they are still there. Somewhere in the hundred thousand square kilometres of Termit and Tin-Toumma there are still addax, dama gazelles and dorcas gazelles. There are Barbary sheep on the massif's black escarpments and Saharan cheetahs that almost nobody has ever seen. The wadis still give shade, the 130 bird species still use the massif as a stopover, and the Toubou and the Tuareg still cross the desert with their herds. Against all odds, Termit is still one of the last places in the world where the Sahara keeps its animals.
