A Monthly Survey of Biodiversity Changes of Waterfowls and Waders in Selkeh and Siah-Keshim (Espand Class) International Wetlands

This project was conducted in Selkeh and Espand International wetlands. The study area in Selkeh and Espand are 78 and 45 ha., respectively. In Selkeh wetland, 57 speacies and in Espand 39 species were identified. The monthly average of waterfowl and wader birds were 5021 and 2695, respectively. Also, avereage density of birds in Selkeh and Espand wetlands were 64 and 60 birds per ha., respectively. During the study period common teal (Anas crecca) was the major species in both areas. The major population in Selkeh was autumn, wintering & spring migrants and for Espand it was winter migrant only. The number of species, population size, biodiversity indices of Menhinick, Simpson and Shanon Wiener diversity and evenness in Selkeh habitat were higher. However, in Espand habitat, only Marga indices were more in number compared to the other habitat.
