This volume is a collection of reports presented at the International NATO Advanced Research Workshop Conservation of the Biological Diversity as a Prerequisite for Sustainaible Development of the Black Sea Region. The seminar was held at Batumi - Kobuleti, Georgia, on the Black Sea during October 5 -12, 1996 with participants from the countries of the Black Sea Region -Georgia, Russia, the Ukraine, Turkey, Bulgaria, Romania, as well as Germany, Italy and the United States of America. The Black Sea Region is an essential and unique part of southern Europe because of its geographical, cultural and historical features. It is the cradle of European civilisation, together with Greece and Rome. For centuries it neighboured onto and interacted with the cultures of the northern and southern Mediterranean, the Christian and Moslim worlds, and was the route of conquerors and migrations of whole nations. Here are closely interwoven the cultures and customs of nations, economic and trade relations, the history of wars and civilised relations of neighbouring countries.
