Grandidier’s Baobab
Grandidier’s Baobab

Common name: Grandidier’s Baobab
Scientific name: Adansonia grandidieri
Height: 30 meters
Diameter: 7.5 meters
Population: The famous “Avenue of the Baobabs” has less than 30 trees, and about 20 to 25 more are scattered in the area.
Distribution: In central western Madagascar
Issue: Slow reproduction, overexploitation for its seeds, its fruits and its oil, fire, seed predation, climate change, habitat degradation, isolation
IUCN Red List status: Endangered

Grandidier’s Baobab is listed as ‘Endangered’ on the IUCN Red List of Threatened SpeciesTM. This large and distinctive tree is found only on Madagascar, where it occurs in scattered locations in the south-west, between Lac Ihotry and Kirindy.

This species is the most heavily exploited of Madagascar’s baobabs; the fruits and seeds are collected for food and for the extraction of cooking oil, the bark is used to make ropes, and the spongy wood is dried and sold for thatch. However, the greatest threat to Grandidier’s Baobab comes from the transformation of its habitat into agricultural land, in which the species appears to regenerate poorly.

Since 2008, the Global Trees Campaign has been involved in the conservation of this species. Grandidier’s Baobab, in particular, is likely to benefit from the creation of protected areas, while formal protection will also be an important step in ensuring its survival. Further research into the extent of bark and fruit exploitation has been recommended, and community education and awareness-raising efforts have been identified as priorities for its conservation.
