Tree of Ténéré
The Ténéré tree was a lonely acacia tree, considered to be the most isolated tree on Earth, the only one within a 400 km radius. It was an important landmark for caravans crossing the Tenere desert.
In 1973, the tree was knocked down by a Libyan truck driver, probably drunk. The dead tree was transported to the National Museum of Niger in Niamey and replaced by a simple metal sculpture representing a tree.

Well of the Ténéré tree
At the bottom of this 36 meters deep well, the water is of poor quality, but necessary for caravaneers. It is brought to the surface by muscle power or with the help of animals.

The Arbre du Ténéré from a distance! This tree was an umbrella thorn acacia (Acacia tortilis) that was considered the most isolated tree on earth - supposedly the only one within a radius of 400 kilometres, other data mention 150 km. It was probably the last surviving tree of a group of trees that grew up when the desert was less dry than at present. The tree stood alone for several decades. - Ténéré - Niger - 1966

During the winter of 1938/39, a shaft was dug near the "Arbre du Ténéré", it turned out that the tree had reached the water table at a depth of 33 to 36 metres. In 1939, the officer Michel Lesourd, stationed in French West Africa, wrote about the solitary tree: "One must have seen the tree to believe its existence. What is its secret? How can it still remain undeserted, despite the multitude of dromedaries near it? How come no camel eats its leaves and buds? Why don't the many Tuareg salt caravans cut its branches and use them as firewood for making tea? The only answer is that this tree is taboo and so respected by caravans." - Ténéré - Niger - 1966

The acacia was knocked down in 1973 by an - allegedly drunken - truck driver. The then lieutenant and later state president Ali Saibou brought the remains of the Arbre du Ténéré in a military van to Niamey to the Niger National Museum on 8 November 1973, where they have been exhibited in their own pavilion since 1977. A tree-like structure made of metal pipes was erected at the site of the acacia, and chrome-plated hubcaps were later attached to its "branches" as reflectors for the night drivers. In 1998, Katsuyuki Shinohara erected the metal sculpture "Lighthouse of the Desert", with glass elements as optical and wind harps as acoustic orientation signs. - Ténéré - Niger - 1966

At the Arbre du Ténéré there are two wells, one with bad water, possibly from a carcass that fell into it. The salt caravans use this place as a night camp. The nomads' campsite near the well is called Ad Azzaouagger. - Ténéré - Niger - 1966

The " Arbre du Ténéré " is actually the sign of a lost waterhole in a desolate desert! Or was, because this legendary tree has disappeared! It was the expected signal for all the nomads passing through, who knew that at its foot there were two wells whose water, although not very inviting, was essential for camels. For those who have understood what the desert is, this souvenir photo is not only very beautiful but also deeply moving. It conveys a religious thought that makes the numerous sun signs depicted in the Sahara's rock art easier to understand. - Ténéré - Niger - 1966

The well by the tree of Ténéré. The mediocre water is found at a depth of 36 metres and is brought up by hand by the Tuareg or Toubou men of the caravans. A few metres further on is a second well, but unusable: a camel has fallen in. – Ténéré – Niger - 1966

The adaptation to dry climates enables dromedaries to live in desert areas. They have the ability to go for long periods without water because they can store a lot of water in their bodies. The dorsal hump contains fat stores that the animal can burn to gain energy when food is scarce. Although the dromedary does not store water in its hump, it does store it in its stomach as needed. The kidneys reabsorb much of the fluid by concentrating the urine heavily. Most of the fluid is also removed from the faeces before excretion. In ten minutes, the dromedary can regain its body weight lost through sweating by absorbing water. - Ténéré - Niger - 1966

Once at the well, water must be drawn, but it is so deep down that a wooden winding roller made on the spot is needed. The hole of the pulley is drilled with the help of an iron rod made red-hot in a camel dung fire. - Ténéré - Niger - 1966

The caravan has made life possible for people in the desert thanks to the camel. In the inhuman aridity of the Ténéré, it is always surprising to find an azalaï, a salt caravan. The blocks of salt it loads have the strange shape of an automobile piston, the rod of which is a little thick ... Each block is wrapped in a mat of palm leaves, because the camels have to be unloaded every evening and reloaded every morning. - Ténéré - Niger - 1966

The Azalaï or salt caravan is the event of the year for the nomads. It always follows the same route because of the rarity of water points. The drivers believe that the trik el-meleh has existed since time immemorial ... In the past, the big caravans included up to 3000 camels. In our days, they number 500 to 1000. The stages stretch over almost 40 kilometres per day, and the load of an animal rarely weighs more than 80 to 100 kilograms. Paradoxically, the caravan leader walks the entire distance. - Ténéré - Niger - 1966
