Azerbaijan is part of the Caucasus Ecoregion, an isthmus between the Black and Caspian seas, which serves as a bridge linking Europe and Asia.
All the Caucasian offices of the WWF have a common ecoregional vision, goals, and objectives identified by the Ecoregional Conservation Plan (ECP), which is the joint work of some 150 experts from the Caucasus. In the east it is washed by the Caspian Sea, while it has long borders with the Russian Federation in the north and with the Islamic Republic of Iran in the south.
WWF ECP identifies 20 focal species for Azerbaijan (five species of sturgeon, five species of birds, and 10 mammals).
Azerbaijan uniquely includes examples of nine of the world’s key climate types, which defines this diversity of species and ecosystems.
Until this century, relative dating was the only technique for identifying the age of a truly ancient object.
By examining the object's relation to layers of deposits in the area, and by comparing the object to others found at the site, archaeologists can estimate when the object arrived at the site.
Carbon-14 has a half-life of 5,730 ± 40 years, meaning that every 5,700 years or so the object loses half its carbon-14.
