THE BIZARRE BAOBAB

If you travel in the remote deserts of Australia, Africa or Madagascar, you may from time to time spot a solitary tree that looks as if it is growing upside-down, with gnarled roots sitting atop a huge, smooth, trunk.

It is well worth taking a closer look at this oddity, which is one of the oldest and strangest living things on our planet. In keeping with its unusual characteristics, it has a weird-sounding name – the baobab, which is probably derived from a native African language.

It is perhaps an exaggeration to say that baobabs are beautiful. Indeed, many people’s first reaction is to giggle at their strange shapes and proportions. With their massive trunks, crooked branches and furry fruit, baobabs have learned how to adapt to a dry and hostile environment – a capacity we may come to envy as the planet starts to heat up.

Though they rarely exceed 20 metres in height, it is not unusual for the circumference of their trunks to be as much or more: it can often take more than ten people with outstretched arms to circle one tree.

They have no branches on the lower part of their smooth, silvery trunks, making them difficult to climb. Instead a spray of twisted boughs sprouts from the top of the trunk, looking like the unkempt hair of a cartoon character.

Baobabs belong to the genus Adansonia and the family Bombacaceae. There are eight different species in the world, of which six can be found in Madagascar. Three of the most common species grow on the west coast of the island: the fony, the grandidieri, and the za. These names are derived from their physical characteristics, which are bottle shaped, flat-topped or upside-down respectively.

The fony is indeed shaped like a bottle with straight sides tapering at the top. The grandieri, which is usually larger than the fony, spreads its branches at an even height. The za, perhaps the most bizarre of all, looks to all intents and purposes like a tree that has grown upside-down with its roots wriggling about in the air.

The secret of the baobab’s success in surviving in harsh environments and the reason for its massive trunk is that it has little wood fibre but a large water storage capacity. Each tree can hold up to 300 litres of water, enabling it to live through long periods without rain. Their life-cycle is as impressive as their bulk – most live over 500 years and some specimens in Africa are believed to be up to 5000 years old.

Since most baobabs grow in isolation and are susceptible to strong winds, they have deep-penetrating roots that allow them to withstand even the wrath of cyclones. They produce leaves for only a short time during the rainy season, when they also develop huge pink or white flowers.

The trees are pollinated by bats and have a fruit as unique as the tree itself. It has a furry coating around a tough, gourd-like shell that shields a soft pulp inside called ‘monkey bread’ and seeds that are rich in citric acid and oil.

The shape of the fruit may be round or oval, giving it the appearance of a leftover decoration on an abandoned Christmas tree. Yet this fruit is so desirable that Madagascan villagers often punch holes in the tree trunk to climb up to them if the tree is too tall for the fruit to be knocked off from the ground.

As with most trees, the baobab is exploited by man. Apart from consuming its nutritious fruit, people use its leaves for medicine and its bark for cloth and rope. While the wood is too soft for building houses or furniture, it can be used to make paper.

The hollowed-out trunks of dead trees have also been used as prisons, toilets and even as tombs. In some parts of Africa, people believe that poets and musicians are possessed by the devil, and that their bodies will pollute the earth if given a normal burial. Thus they are consigned to the bowels of a baobab.
Baobab legends

The importance and uniqueness of baobabs to the communities living in barren areas has guaranteed them a major role in the world of myths and legends. Just outside Morondava, on the west coast of Madagascar, an enormous specimen called ‘the sacred baobab’ is believed to have sprouted on the exact spot where a princess died about 800 years ago. It is now surrounded by dense growth and only its crown is visible above the thicket.

A little further up the coast, two baobabs nicknamed ‘the lovers’ are entwined around each other in an embrace that has lasted over 600 years. However, the most popular place for baobab spotters is ‘Baobab Alley’, twenty bumpy kilometres north of Morondava.

Baobabs are usually solitary beings, standing tall and proud in the midst of empty spaces. Yet in Baobab Alley, they cluster together forming an avenue of towering columns that border the dirt road, their tortured and twisted tops reflected in the lily-covered pond at the roadside.

The best time to visit these gentle giants is at twilight, when their stark silhouettes form a spectacular contrast to the soft, calming colours of sunset. As the colour fades and lens covers are replaced on cameras, a small group of admirers shuffle reverently away, speaking in hushed tones about this mute yet extremely expressive form of life.

Baobab tree

The African baobab, Adansonia digitata – the classic wide-trunked tree of the African plains, with its unusual “upside down” silhouette when leafless in winter – is the most famous of this genus of eight species in the kapok family (Bombacaceae – which some scientists now consider to be part of the Malvaceae) named after the French surgeon Michel Adanson (1727-1806).

It is the only species native to Africa. It is one of the largest trees in the world, although definitely not one of the tallest, with its impressive, broad trunk that can reach over 15m in diameter. Its sheer size makes it quite conspicuous in the savannah or bushveld (dry woodland). Some of the largest trees have been estimated at over 2,000 years old by carbon-dating; circumference is not a reliable predictor of age, as the conditions it has grown under and the climatic fluctuations of the centuries greatly affect girth. Rainfall influences tree diameter, with the trunk becoming narrower in dry years. The baobab’s trunk is fibrous and saturated with water.

The massive swollen trunk consists of soft spongy wood saturated with water.  The fibrous wood cannot be used for building or firewood, but the bark can be shredded into strands to use as fiber for ropes, baskets, nets, cloth and other uses. Many living trees develop hollow trunks with age, which have been used as homes, storage units, a post office, chapels, prisons or tombs. A tree at Katimo Mulilo, Namibia was converted into a flush toilet, while another near Gravelotte in Limpopo Province, South Africa served as a bar for gold miners.

Native to semi-arid regions of sub-Saharan Africa, it grows up to 80 feet tall and up to 40 feet in diameter.in any rocky, well-drained soil. The smooth grey bark has distinct “folds” covering its immense trunk. The alternate leaves are simple on juvenile plants, but are digitately compound with 3-9 leaflets on mature plants. Young leaves are eaten like spinach or dried for later use by some indigenous peoples.

Adansonia digitata trees, the only remaining native vegetation in sisal fields between Kilifi and
Mombassa, Kenya (L); baobab in leaf (R).

Baobabs first flower when they are about 20 years old. Large, white, slightly scented flowers with purplish stamens are produced in midsummer. A. digitata is the only species in the genus with pendulous flowers. The flowers open at sunset and are pollinated by fruit bats as they feed on the sweet nectar. The flowers only bloom for a short time, dropping to the ground within hours of being pollinated.

The flowers are followed by globose fruits with a hard woody shell covered with short yellowish hair. Inside are hard, kidney-shaped seeds in a powdery, creamy white pulp (from which ‘cream of tartar’ is derived). The pith contains high levels of ascorbic acid (Vitamin C), tartaric acid and citric acid and is used in producing a refreshing lemonade-like drink that has been used to treat fevers and diarrhea. Many animals including baboons, monkeys, antelope and elephants, will feed on the fallen fruits and help disperse the seeds. The seeds may be ground to make a coffee-substitute or eaten fresh, and are often fed to cattle or goats, especially near the end of the dry season.

Ecologically, baobabs are very important in the savannah, providing food and shelter for a great variety of animals. All kinds of small birds, squirrels, rodents, lizards, snakes and tree frogs, as well as spiders, scorpions and insects live in the canopy. Red-billed buffalo weavers build their communal nests in baobabs more than any other tree. Other birds such as rollers, hornbills, parrots, kestrels and spinetails nest in holes in the trunk, while barn owls and ground hornbills take advantage of larger cavities. Large stick nests of eagles, vultures and storks are often seen on the outer branches. Elephants are one of the biggest threats to the African baobab, especially in areas with high elephant populations. The animals can easily kill small trees as they tear off pieces of stem for the moisture.

This genus of tropical trees is native to Africa, Australia and Madagascar, but baobabs have been widely planted in other tropical and warmer subtropical areas. A. digitata is native to Africa and Madagascar, while the other species except A. gibbosa are all endemic to Madagascar.

– A. gibbosa (gregorii), the Australian baobab, is small and irregularly shaped, and often has multiple trunks. It is restricted to the northwestern area of Australia.
– A. grandidieri, which occurs near Morombe and Morondava in western Madagascar, may be the best known of the Malagasy baobabs. They are very tall trees with a smooth, cylindrical trunk topped with a flat crown of horizontal branches.
– A. madagascariensis is found in dry or moist forest in the Mahajanga province and in the far north. The trunks of these small to large trees (16-65 feet tall) vary in shape from bottle-like to cylindrical.
– A. perrieri is restricted to a small area near Antsiranana (Diego Suarez) in the far north of Madagascar. It is a medium to tall tree (up to 100 feet tall) with an irregular crown and thick branches, often ascending at 45°. The flowers are white to pale yellow.

– A. rubrostipa (fony) is the smallest of the Malagasy baobabs, usually growing only 12-15 feet tall, but sometimes as much as 60 feet. The bottle-shaped trunk has a distinct constriction beneath the branches. Its flowers are bright yellow to orange yellow.
– A. suarezensis is restricted to a very small area near Antsiranana. These endangered trees grow to 80 feet tall, with a single trunk and horizontal branches in the flat-topped crown. This photogenic species has reddish bark that is particularly dramatic at sunrise. White flowers are followed by long, irregularly-shaped fruit.
– A. za is the most common species in Madagascar, growing in the south, west and northwest. The single trunk grows 15-100 feet tall, with a cylindrical or slightly tapering and swelling shape. Yellow flowers are followed by black, oblong fruit.

Although baobabs will not survive outdoors in the Midwest, they are sometimes grown as a curiosity. Many are amenable to being grown as bonsai specimens. All need well-drained soil and good sunlight, so are best grown in a greenhouse rather than as a houseplant and benefit from moving outside to enjoy thunderstorms and warm summer weather. They all have a well-developed taproot even when young which may necessitate a deeper than normal pot. They do not begin to develop their characteristic trunk shape until much older, however, so will never resemble the classic savannah tree shape when container grown, but frequent tip-pruning will encourage thickening of the trunk.

Adansonia digitata Baobab

Baobab is the common name of a genus (Adansonia) containing eight species of trees, native to Madagascar (having six species), mainland Africa and Australia (one species in each). The mainland African species also occurs on Madagascar, but it is not a native of that country.

Other common names include boab, boaboa, bottle tree, upside-down tree, and monkey bread tree. The species reach heights of 5 to 30 metres (16 to 98 ft) and trunk diameters of 7 to 11 metres (23 to 36 ft). An African Baobab specimen in Limpopo Province, South Africa, often considered the largest example alive, has a circumference of 47 metres (150 ft) and an average diameter of 15 metres (49 ft).

Some baobabs are reputed to be many thousands of years old, which is difficult to verify as the wood does not produce annual growth rings, though radiocarbon dating may be able to provide age data.

The Malagasy species are important components of the Madagascar dry deciduous forests. Within that biome, A. madagascariensis and A. rubrostipa occur specifically in the Anjajavy Forest, sometimes growing out of the tsingy limestone itself.

Beginning in 2008, there has been increasing interest for developing baobab as a nutrient-rich raw material for consumer products.
Species

* Adansonia digitata – African Baobab (western, northeastern, central & southern Africa)
* Adansonia grandidieri – Grandidier’s Baobab (Madagascar)
* Adansonia gregorii (syn. A. gibbosa) – Boab or Australian Baobab (northwest Australia)
* Adansonia madagascariensis – Madagascar Baobab (Madagascar)
* Adansonia perrieri – Perrier’s Baobab (North Madagascar)
* Adansonia rubrostipa (syn. A. fony) – Fony Baobab (Madagascar)
* Adansonia suarezensis – Suarez Baobab (Diego Suarez, Madagascar)
* Adansonia za – Za Baobab (Madagascar)

The name Adansonia honours Michel Adanson, the French naturalist and explorer who described A. digitata.
Water storage

Baobabs store water inside the swollen trunk (up to 120,000 litres (32,000 US gal)) to endure the harsh drought conditions particular to each region. All occur in seasonally arid areas, and are deciduous, shedding their leaves during the dry season.
Uses
The fruit is about 18 cm long

The leaves are commonly used as a leaf vegetable throughout the area of mainland African distribution, including Malawi, Zimbabwe, and the Sahel. They are eaten both fresh and as a dry powder. In Nigeria, the leaves are locally known as kuka, and are used to make kuka soup.

The fruit is nutritious possibly having more vitamin C than oranges and exceeding the calcium content of cow’s milk. Also known as “sour gourd” or “monkey’s bread”, the dry fruit pulp separated from seeds and fibers is eaten directly or mixed into porridge or milk. In Malawi, the fruit pulp is used to make a nutrient-rich juice.

The fruit was once used in the production of tartar sauce. In various parts of East Africa, the dry fruit pulp is covered in sugary coating (usually with red coloring) and sold in packages as a sweet and sour candy called “boonya” or “bungha”.

The seeds are mostly used as a thickener for soups, but may also be fermented into a seasoning, roasted for direct consumption, or pounded to extract vegetable oil. The tree also provides a source of fiber, dye, and fuel.

Indigenous Australians used baobabs as a source of water and food, and used leaves medicinally. They also painted and carved the outside of the fruits and wore them as ornaments. A very large, hollow baobab south of Derby, Western Australia was used in the 1890s as a prison for Aboriginal convicts on their way to Derby for sentencing. The Boab Prison Tree still stands and is now a tourist attraction.

The whole fruit of the baobab is not available in the EU as current EU legislations from 1997 dictate that foods not commonly consumed in the EU have to be formally approved before going on sale. On 15 July 2008, the EU approved parts of the fruit for use in smoothies and cereal bars. Traditional uses of the whole fruit are unlikely outside of Africa as the fruit will be processed for export as a white powder with a cheese-like texture to be used as an ingredient in products.

Culture and myths
Adansonia grandidieri, Madagascar
Adansonia digitata, Tarangire National Park in Tanzania
Baobab in Recife. Possible inspiration for Saint Exupéry

* The national tree of Madagascar.[citation needed]
* Used for bonsai (the most popular being A. digitata).
* Known colloquially as “upside-down tree”, it is cited in African lore: after creation, each of the animals was given a tree to plant and the hyena planted the baobab upside-down.
* Tabaldi is the name of the Baobab tree in Sudan and its fruit is Gongalis. Baobab’s trunk is used as a tank to store water. People in west Sudan use the hollow in the trunk to save water in the rain season. Gongalis is used to make juice or use to cure stomach and other diseases.
* Bark may have been used hundreds of years ago in Africa as a backscratcher or toothbrush.
* Having a distinctive foul smell, tree parts may have been used by primitive tribes to ward off evil spirits, making the tree known in African folklore as “God’s Thumb.”
* Rafiki, in The Lion King, makes his home in a baobab tree.
* Ernst Haeckel mentions “monkey bread-fruit trees (Adansonia)” in his The History of Creation (Chap. 29), and claims that their “individual life exceeds a period of five thousand years”.
* The owners of Sunland Farm in Limpopo, South Africa have built a pub called “The Big Baobab Pub” inside the hollow trunk of a 22 metres (72 ft) high baobab. The tree, which is 47m (155ft) in circumference, is reported to have been carbon dated at over 6,000 years old.
* Baobabs are cited in the The Little Prince as a tree that may “split” a small planet into pieces.

バオバブは、キワタ科(bombacaceae)Adansonia

学術的に見ると…バオバブは、キワタ科(bombacaceae)Adansonia 属の樹木です。アフリカ、マダガスカル、オーストラリアに約9種があり、そのうち6~7種がマダガスカルに特有の種類です。

マダガスカル最大の樹は幹が直径7m、樹高30m、樹齢500年以上に達すると推定されます。学名のAdansonia は、この木の発見者のフランス人植物学者 M.Adanson にちなんでいます。

マダガスカルってどんなところ?

アフリカ大陸の東のインド洋に浮かぶ世界第4の大きな島で、独特な動植物で知られています。ここの住民は、1500年ほど前に東南アジアから移り住んだ人々の子孫と言われており、人口約1200万人の独立国です。米を主食とし、水田のある風景は“アフリカの中のアジア”という表現がピッタリです。

バオバブの木は何かの役に立つの?

バオバブの木は、その姿が人を感動させるだけでなく、とても役に立つ木です。果実の中の甘酸っぱいパルプ質の果肉がお菓子や清涼飲料水に、堅い果実の殻は容器に利用されます。マダガスカルでは地方によって種子から油を採り、樹皮を家の屋根や壁に用いたりロープの材料や薬にします。アフリカでは葉を乾燥して粉にし、野菜のない季節の保存食品とします。変わった使い方として、生きた木の幹をくりぬいて貯水タンクにしたり(マダガスカル南東部)、自然にできた木のウロをお墓(アフリカ)や、牢屋(オーストラリア)にする例があります。

バオバブの木はなぜ絶滅の心配があるの?

バオバブはもともと森の中に生える木です。放牧地の開発などで森が焼き払われた時、火に強いバオバブの木は生き残り、草原にバオバブだけがそびえ立つ景色となります。その景色はすばらしく、感動的でさえあるのですが、このような草原では種子が稔っても若木が育つことはなくなり、老木が死に絶えると絶滅することになるのです。マダガスカルでは今、このような状況がどんどん進行しています。

どんな方法でバオバブの木を保護するの?

バオバブの木を保護するには、バオバブが生える森をそっくり保護するのが一番です。しかし、すでに森が荒れている所も多いのが現状です。そのような場所では森を復元し、そこにバオバブの苗木を植えてゆくことが望まれます。森の中なら、やがて植えたバオバブが大きくなって果実を稔らせ、その種子からまた新しい若木が育っていくことが期待できるのです。

「バオバブの木 里親」基金とは、どのような基金ですか?

マダガスカル南部で取り組んでいる活動は、失われ行く貴重な森とそこに生きる動植物を、森の恵みで生活する人たち自身の力で守ってゆくことを目指しています。この基金は、バオバブの苗木の里親となられる方々からの募金を、現地育苗センターへの整備、荒れ果てた森を元に戻すための苗木作りと植え込み、森とその資源を守るための子供たちへの教育、地元住民の生活環境の改善、自然観察ガイド養成と貴重な動植物の保護などに役立たせていただこうとする資金です。

里親にはどのような役割や特典があるのですか?

* お申し込みとご送金次第、本会本部と現地事務所に里親として登録し、本部より領収書と関係資料をお送りします。また、現地に植え込んだ苗が活着したことが確認された後に、現地から感謝状が送付されます。
* 里親に代わり、現地スタッフが種子から育てたバオバブの苗木を募金一口につき1本、現地の自然林復元予定地に植え込みます。
* 現地に行きバオバブの苗をご自分で記念植樹することもできますので、その際は本会本部にご連絡ください。旅費その他の経費はご自分の負担となります。
* 現地に設置した記念碑の芳名板に、里親のお名前を刻みます。
* 植えられた苗木の世話は、里親に代わって現地スタッフが行ないます。
* バオバブの現地産種子と「育て方の手引き」をお送りします。記念として残されるのも、播いて苗木をお育てになるのもご自由です。なお、ご自分で育てられたバオバブの苗木を国内で記念植樹ご希望の場合は、本会本部にご相談ください。

里親に期限はあるのですか?

マダガスカルの自然と「バオバブの木」を愛するかぎり、里親として資格に期限はありません。  バオバブの寿命は数百年から数千年以上と言われ、親の資格はバオバブと共に生き続けます。本会は、少なくとも活動地の森が「自然林保全モデル地区」としてマダガスカル政府の指定を受け、皆様のバオバブの木が末長く育ち続ける環境が整うまで活動を続けます。
