 The baobab is a magnificant  tree indeed.  You would not want to cut one just for material for a hugel bed, but if you have access to already cut wood, I see no problem with using it...a tree that gives life while standing, can do the same once fallen.  The tree of life can give life to the foods you grow as well as spiritual life to the humans around it.  Please, tell us more about yourself, and the region where you wish to raise a permaculture food system.
