Abstract: 

The study of species diversity of vertebrates in Ardabil Province is one way to identify the strengths and weaknesses of the natural environment of the proVince for the protection and management of species and habitat. In this research project, we have collected and produced information through conducting a field operation. As a first step, Ardabil's ecosystem was classified and identified and, after scoping, the ecological factors (climate, water sources, plant cover, shelter and security) were studied. For the next step, vertebrates were identified separately, classified in terms of species, habitat and nutrition, and evaluated according to national, CITES and IUCN standards. In this way, index species' were determined and their population was measured by direct observation. The population density was estimated at the base level along with the minimum population, dispersed areas in the province were specified and their biological conditions and other species present were also identified. In most habitats, four main factors-water, food, security and shelter-are threatened by destruction, hunting and human activities. So, index species face population decrease and biological crisis and, out of a total number of 287identified vertebrates, 8 species are in danger of extinction and 62 species supported. According to international standards, 39 species are listed in a CITES appendix and 2 species are in the IUCN Redbook. Furthermore, the generation of two species of Goitered gazelle and Greal bustard in this province’s habitats has become extinct. Destruction of habitat, lack of ample security and decrease in food resources are the main factors leading to the extinction of species, and the responsibility of each of these factors has been estimated at 53% -39%, 4%, respectively. The preservation of habitat by establishing protected areas in Agdag and the preservation of species by setting up a prohibited hunting area in the Sabalan Mountain and Aras River areas are the main management policies for the conservation and protection of the animal community in Ardabil Province.
