Abstract

Kashmir is the northwest region of the Indian subcontinent. It is ethnically diverse Himalayan region, covering around 222,738 sq Km and famous for the beauty of its fresh water bodies which are directly linked to the livelihood requirements of the local populations apart from their ecological, biodiversity, cultural and tourism values. Apart from being the primary habitat for hundreds of species of waterfowl, fish, mammals and insects they receive a wide variety of migratory birds from Siberia, Northern Europe and Central Asia during the winter months which add to the beauty. Although there are wetlands all around the valley, some of the larger ones which have been designated as Ramsar sites in Kashmir include Hokersar, Haigam, Shallabugh, and Wular. In which Hokersar and Wular Lake is Asia's largest freshwater lake. Out of four main wetlands in the valley Hokersar wetland is the site of the current investigation. Many resident and migratory birds find it to be a good habitat. A large diversity of the area's avifauna can find ample cover, secure roosting locations, and feeding grounds in this wetland. This wetland is also an ideal breeding place for many local and seasonal bird visitors. The coordinates for the Hokersar wetland are 34 0 7' N and 74 0 39' E. With an elevation of 1584 meters above mean sea level, it is located to the north-west of Srinagar City, 16Kms from Srinagar on Srinagar Baramulla road National highway and has a sub-Mediterranean climate. Due to encroachment and siltation, the Hokersar wetland, which formerly covered a vast 13.26 sq. km, has gradually shrunk to a size of 7.5 sq. km. In Kashmir Valley, Hokersar is regarded as the migrating bird's paradise. However due to the increased rate of anthropogenic activities changes in the natural process can be seen, Hokersar wetland is degrading at an alarming rate and affecting water quality. The major threats to this wetland include pollution, land use, climate change, urbanization and encroachment. These major threats during the past few years have resulted in degradation of wetland over this region. The present study assesses the avian diversity of Hokersar bird conservation wetland Srinagar. During the present study a total 76 species of birds belonging to 14 orders and 36 families were recorded. These comprised of Summer visitors 26 species, Winter visitors 20 species, Residents 21 species and Local altitudinal migrants 9 species. Study revealed that no species restricted itself to only one particular habitat and only maximum density was found in that habitat. Anthropogenic interference in the form of illegal hunting, macrophytic harvesting, boating and severe cold climatic conditions during the winter season greatly reduced the diversity of the avifauna. Sustainable management of Hokersar wetland is crucial as this ecosystem offer an array of ecological functions. This study provides special insight about the significant changes in spatial scale.
