Theoretical Models for Regeneration of Medicinal Plants and Their Application in Sustainable Wild-Habiodiversity hotspots on earth, selected because of their high plant diversity and endemism. These ecosystems represent 20 percent of the world ’s flora in only 5 percent of the earth’s surface (.). The risk to their flora from an increase in population density is another reason for their selection as hotspots (.).
