The seed regions are created for main commercial tree species and the rules for transfer among these regions are described. The geobiocoenological landscape differentiation and differences among tree species populations were used as main approaches. The same principle is used for Boswellia seed regions differentiation on Socotra island. Eight species of Boswellia genus were determined on the island, all species being endemic. The differentiation is based on Boswellia populations field survey. All populations were described in morphological signs. The vegetation zones and geomorphological differentiation were also taken into account. The result is a map of seed regions for every Boswellia species on Socotra island presented in the article. Key words: Boswellia, Socotra, Seed regions, Biodiversity, INTRODUCTION The vegetation of Socotra island is no doubt one of the most interesting and specific ones in the world (Brown & Mies, 2012; Cheung & Devantier, 2006). Due to an extreme heterogeneity of Socotra vegetation, it is considered, without any exaggeration and from many points of view, to be islands on an island; classical taxonomic approaches deal with a variety of problems, especially with the study of lower taxons and populations (Batelka, 2013).
