Are specific characteristics/traits being targeted?
Yes
Large trees with a total bark surface of 14.8 ± 0.3 m2 were preferred for bark extraction; Smaller trees with a total bark surface below 13.2 ± 0.4 m2 were left intact.
Purpose of Use
Basic subsistence (meeting day to day essential needs)
Additional Details (if available)
the bark is used to make ropes

Details of assessment carried out
This study showed that more than half of the Grandidier’s baobab trees in the wild have been subject to bark extraction. Since only part of the bark has been removed, the trees are still standing many years after the extraction. However, we started to observe intensive harvesting which consists in cutting down the trees to remove all the bark. If this practise continues, it will cause the de- cline of the species in the short term
On one hand, community members argue that bark removal do not harm the baobab trees while they agree that bark does not regenerate. However, in the wild, the baobabs are still standing. On the other hand, scientists advocate that bark harvesting might represent a threat to the trees as they are more exposed to ecological and climatic threats; Other studies in Africa reported that bark harvesting affects negatively the survival of baobab trees ;
In this paper, it is estimated that if this demand for bark remains constant, all baobab trees in the Menabe region would be debarked within the next 39 years. This could result in local extinction of the species in the near future, thus pointing out that as it is, the practice is unsustainable.
