Abstract

To investigate the changing trend of diversity indicators of aquatic and waterfowl overwintering birds in Choghakhor Wetland, the half-winter data are done by Environmental Protection Department of Chaharmahal and Bakhtiari province in 1995, 2000,2005,2010, and 2015 and are investigated. Shannon-Weiner, Simpson, Margalef species richness, and Simpson uniformity indicators for aquatic and waterfowl species in Choghakhor wetland have been investigated during studied years. The maximum and minimum values of the Shannon Diversity Index were obtained 4.61(2005) and 4.39 (2010), respectively. According to the Simpson Diversity Index, the maximum values were obtained in years1995, 2000, and 2005 (0.96) and the minimum values were obtained in year2010 and 2015 (0.95). In terms of Margalef species richness, the maximum and minimum species richness were determined in 2005(2.86) and 2015(2.23), respectively. Based on Simpson's uniformity index, the maximum and minimum uniformity in Choghakhor Wetland were determined in995, 2005 (0.89), and 2010 (0.86). The numbers of aquatic species were more than other species. Also, the aquatic birds were more than other species. It seems that the Chaghkhor wetland had better ability to provide nutrition resources for aquatic species and this problem has been highlighted by observing more aquatic birds than species.
