Israel and its surrounding region is characterized by a wide range of agro-climatic conditions, which account for the enormous diversity of biological resources that exist in this country. Located at the eastern end of the Mediterranean, Israel is the meeting point of four major phytogeographical regions: the Mediterranean, the Irano-Turanian, Saharo- Arabian and Sudanian. Its flora exemplifies the broad and in many ways unique diversity of plant species of the coastal plain, the mountains, the Negev/ Arava and the Jordan and Jezreel valleys. Danin (2004) lists 2750 species and 138 plant families in this country. About 10% of these species are related to the Old World crop plants or are being used in folk medicine or as spice plants.
