Abstract :

This paper presents data from a fifteen-year (1998-2012) monitoring of migratory wintering waterfowl and waderand#39;s fauna species diversity in Arjan International Wetland. During a 15 periods from 1998 to 2012, a total of 309674 wetland birds composed of 71 species from16 families and 6 orders of the birdandrsquo;s fauna of Iran were observed during the course of this study. The most common species counted was the common teal (Anas crecca) with a total of 51248 individuals. The results indicated that among families of migratory wintering waterfowl and waders in Arjan international wetland the largest family was Anatidae with 80.496 percent abundance and the lowest was Ciconidae with 0.018 percent. In these periods of studying, year of 1999 with 77580 individuals has the highest population numbers and year of 2011 with 1002 individuals has the lowest. The highest and lowest species richness was recorded in years of 2004 and 2011 with 38 and 6 species, respectively. The results show that waterfowl fauna with 81.03 percent and waderand#39;s fauna with 18.97 percent has the highest and lowest abundances in this period, respectively. According to the results of species diversity and evenness the year of 2004 has the highest biodiversity of migratory wintering waterfowl and waderand#39;s fauna in Arjan International Wetland and the year of 2010 has the lowest biodiversity (P andlt; 0.05).
