There is a widespread perception that the Caspian is in a state of ecological decline, and that one aspect of this is a decline in biodiversity.  This is of particular concern, due to the status of the Caspian as a unique water body inhabited by a large number of endemic species.  There is also a widespread belief that the Caspian is very sensitive to the impacts of industrial activities and in particular to those associated with oil and gas production and transportation.

The Caspian Sea, world largest lake, is bordered by Republic of Azerbaijan, Islamic Republic of Iran, Kazakhstan, Russian Federation and Turkmenistan. Out of 122 fish species and subspecies living in the Caspian Sea, 40 species are believed to be commercial and presently 25 species are the main exploited fish (Ivanov, 2000). At present sturgeons, tulka and Caspian Sea seals are considered as shared commercial stocks between Caspian Sea range states.

The tourist brochure describes interesting species of flora and fauna of the Ural River Delta and the adjacent coastal zone of the Caspian Sea.

This brochure has been produced on behalf of the consortium developing the hydrocarbon deposits beneath the North East Caspian defined under the North Caspian Sea Production Sharing Agreement of 1997.

The concession area lies in a region of rich biodiversity recognized as being of international importance for its wildlife, including several species that are classified as endangered. The widely varying conditions in the North East Caspian include extreme seasonal temperature variations, long-term sea level change, short-term sea surges and retreats, high levels of turbidity and sediment movement, ice cover in winter and scouring of the seabed by moving ice.

This dynamic environment presents challenges for those who live and work in the area. It also means that the fauna and flora on land and at sea, are adapted to a significant level of environmental stress from continually changing physical conditions.
