Abstract

Biodiversity and population changes of waterfowl and waterside birds are considered as one of the indicators of evaluating the desirability of coastal habitats. In this research, the biodiversity of Waterfowl and waterside birds in the coastal habitats of Chabahar has been investigated and evaluated in a four-year period. In the four-year census in five coastal habitats of Chabahar, which was carried out by the total counting method, 43,946 birds belonging to 6 orders, 13 families and 46 species of Waterfowl and waterside wintering birds were observed and identified Waterfowl species with 82.62% and waterside species with 17.38% of all birds were included. The Laridae family was counted with 53.18% of the most birds. And the Charadriidae family (Plovers) with 20 species had the highest species diversity among Waterfowl and waterside wintering birds. The study of bidiversity indices showed that the highest species diversity index of Shannon Weiner belonging to Govater habitat in 2018 ( ) and the lowest related to the Pasabandar habitat in 2016 ( 1/68). The highest species richness index of Margalef related to Govater habitat in 2017 the (R=5/25) and the lowest value related to the Pasabandar habitat in 2016 (R=2.43). The highest value of Pielou's evenness index related to the Govater habitats was J=0.77 in 2016 and the lowest value was J=0.56 for the Pasabandar habitat in 2018. The highest value of Simpson's dominance index related to Govater habitat (D = 0.93) in 2017 and the lowest value related to Govater habitat (D = 0.08) in 2016. The highest value of Berger-Parker index number related to Pasabandar habitat (d=0.45) in 2017 and the lowest value related to Govater habitat (d=0.17) in 2018. The highest value of Buzas-Gibson's evenness index related to the Ramin habitat ( =0.24) in 1998 And the lowest value related to the Pasabandar habitat ( in 1997. The results of biodiversity indicators show that Govater and Tis habitats have more favorable conditions for aquatic and aquatic migratory birds than other habitats (p>0.05).
