AVIFAUNA: Not much work has been done on this Sanctuary, but Choudhary et al. (1992) have identified 83 species of birds, including many forest species. The list includes such rarities as Nordmann’s Greenshank or Spotted Greenshank Tringa guttifer but this needs confirmation. A. Mishra (pers. comm. 2001) has sighted the Near Threatened Black-necked Stork Ephippiorhynchus asiaticus. At present, it does not qualify in A4iii criteria but once it is properly protected, Udhuwa has great potential to become an important waterfowl refuge (A. Mishra pers. comm. 2001).
OTHER KEY FAUNA: There are not many large mammals of conservation concern. The lake has about 22 fish species, most of them of commercial value (Choudhary et al. 1992).
Charaching of birds and illegal fishing are the biggest challenges for the Forest Department ever since it was declared as a bird sanctuary under the Indian Wildlife (Protection) Act. The surrounding hillocks suffer a severe threat due to heavy influx of suspected illegal Bangladeshi migrants who have settled beside the lake and have added to the demand on the surrounding natural resources. Also, the area surrounding both the lakes is used for agriculture, and in summer when the water-level of Berhale recedes, the exposed land is also used for agriculture.
