Abstract

Gomishan marsh is located on the east coast of the Caspian Sea, about 20000 hectares in size. It receives its water from the Caspian Sea as well as Atrak River. This study was conducted to determine DENSITY, DIVERSITY and Population Trend of Wintering Waterbirds in GOMISHAN International marsh in Golestan Province during 2007-2012. Total count method was used to determine the number of waterbirds during 30 December to 24 January each year. 400591 waterbirds of 84 species belonging to 12 families were counted in GOMISHAN marsh. The GOMISHAN marsh hosted more waterbirds than other wetlands which are due to its larger size as well as its ecological characteristics. GOMISHAN marsh plays an important role in conservation of the protected waterfowl and waders; the highest numbers of waterbirds were 115263 in 2007 and the lowest numbers of waterbirds were 58583 in 2012. The heist abundance of waterbirds belongs to Phoenicoterus ruber with 28.11% and the lowest was Treskiornitidae with one percent. The heist species richness was 4.983 in 2007 and lowest was 3.658 in 2012 (Margalef's Richness). Camargo Evenness was 0.230 in 2007 and it was decreased to 0.081 in 208.Therefore, the total number and species number of waterbirds in GOMISHAN marsh showed decreasing from 2007 to 2012.
