The Study of Species Diversity of Migratory Wintering Waterfowl and Waders in Boushehr Site

This research presents data from a ten-year (2002-2011) monitoring of migratory wintering waterfowl and wader's fauna species diversity in Boushehr site (wetland habitats ofBoushehr beaches). The results showed that during a 10 periods from 2002 to 2011, a total of113606 wintering birds composed of 78 species from15 families and 6 orders of the bird’s fauna of Iran were observed in the Boushehr site. The most common species counted was the Blackheaded Gull (Larus ridibundus) with a total of 57087 individuals. The results indicated that among families of migratory wintering waterfowl and waders in Boushehr site the largest family was Laridae with 59.96 percent abundance and the lowest was Pelecanidae with 0.02 percent. In these periods of studying, year of 2007 with 28043 individuals has the highest population numbers and year of 2008 with 1112 individuals has the lowest. The highest and lowest species richness recording in years of 2011 and 2008 with 56 and 23 species respectively. The results showed that in this period wader's fauna with 88.30 percent and waterfowl fauna with 11.70 percent respectively has the highest and lowest abundances. According to the results of species diversity and evenness the year of 2011 has the highest biodiversity of migratory wintering waterfowl and wader's fauna in Boushehr site and year of 2006 has the lowest biodiversity (P < 0.05).
