These qualities sometimes contribute to the conservation of these environments. Sacred forests are found the world over. They are the abodes of Gods or Ancestors to which people assign a protective role over their community or village, even over the natural world. Restrictions are imposed which favour the total or partial preservation of vegetation cover and biodiversity. In some communities, trees are spared from clearcutting for their food or medicinal resources, soil fertilisation and their role as shelter for animals. Such practices require a refined knowledge of the environment and the different tree species, and therefore a long learning period. For the Mentawai of the island of Siberut, off Sumatra, spirits inhabit the forest. Anything taken from this environment must be given back to maintain a balance.
