Species Diversity of Parver Protected ‎Area in Semnan Province

Studying on the species diversity and evaluating the variation of it during different years has had very important role in identifying the changes and weak wildlife management. In this survey we did a study on species diversity and population variation of terrestrial bird of Parvar Protected Area in Semnan province during a year. Parvar Protected Area is one of the critical habitats which have the capability of promoting a higher level of Iran protected areas category as a national park. Climate variation has led to species diversity and we could identify more than one fourth of the bird species existing in the whole country. North and northwest forests of Parvar which are the borders of Iranian Hircanian forests and Irano-touranian climate in the east and southeast where have resulted in the high species richness. We identified 161 bird species belonging to 13 orders. The most known bird species are related to the summer with 2063 pieces. 47 species are native, 21 species were identified in nesting season, 18 species were identified in winter and others were passing species. Passeriformes were dominant by 68% and Falconiformes were about 13%. We could identify only one water bird, Common Teal, and two shore birds during the study period.
