The Samaspur Bird Sanctuary, in the Raebareli district of Uttar Pradesh, is a perennial lowland marsh typical of the Indo-Gangetic Plains. Its six connected lakes are heavily relevant on monsoon rains. Annual counts regularly find more than 75,000 birds present, with over 250 resident and migrant species documented. The Sanctuary harbours threatened species such as the endangered Egyptian vulture (Neophron percnopterus) and Pallas’s fish eagle (Haliaeetus leucoryphus), and more than 1% of the South Asian population of the vulnerable common pochard (Aythya ferina). At least 46 freshwater fish species use the wetland, with some migrating in from nearby rivers during monsoon flood periods. The Site provides food products and agricultural fodder, as well as maintaining this biodiversity. However, invasive species threaten its ecological character, with over 40% of documented floral species being exotic. The Office of the Conservator of Forests (Wildlife) and State forest officers undertake joint management of the Sanctuary.
