Geography
The Hokersar wetland, which is the largest bird reserve in the Kashmir Valley, is situated in the Jehlum River basin. It is the northernmost part of the Doodhganga catchment, at an altitude of above sea level. The reserve is fed by the two perennial inlet streams; Doodhganaga from the east and Sukhnag from the west. It includes a lake and a marshy area with an average depth of . In the spring, the water level rises to as much as due to runoff from

The Valley of Kashmir as a whole is strategically located south of the Pamirs and at the western extremity of the Himalayan range. The waterbirds fly to Kashmir Valley via the Central Asian Flyway. They begin to arrive in September–October and leave by May. Over 500,000 waterbirds were recorded in the Hokersar Wetland in 2000–01. There were seven globally threatened species among the 45 waterbird species and 66 wetland-associated bird species reported in the reserve.

Threats
Threats to the Hokersar wetland include human activities and encroachments. The wetland has been reduced from in 1969 to in 2008. Over time, many areas of the wetland have been converted into paddy cultivations. Discharge of the domestic waste into the wetland, primarily through the inlet streams, has led to excessive weed growth and eutrophication, both of which pose a great threat to the reserve's flora.
