Caucasus Nature Fund
Formed by the isthmus between the Black and Caspian Seas, the Caucasus ecoregion is a biological crossroads, where plant and animal species from Europe, Central Asia, the Middle East, and North Africa mingle with endemic species found nowhere else on earth. About the size of France, the hotspot spans 500,000 square kilometers including Armenia, Azerbaijan and Georgia, as well as small portions of Russia, Iran and Turkey. Amazingly, this relatively small area holds 9 climate zones from semi-desert to high altitude tundra, from alpine meadow to deep forest. Here you can find over 6,400 plant species, 348 birds, 131 mammals, 86 reptiles, 17 amphibians and 127 freshwater fishes.
