The objective of the study was to assess bird and fish species diversity, relative abundance and threats of Lake BahireGiorgis. Abundance of waterbirdand fish species composition of Lake was studied in dry and wet season in August 2017 and January 2018.Physico-chemical parameters of the Lake were identified using standard methodologies. Parameters such as electrical conductivity, PH, nitrate, Sulfite, Phosphate, TDS and Temperature values are within acceptable limits in contrast contained high amounts of alkalinity, total hardness and Turbidity. The study of fish diversity assessed through catches from four sites of the Lake. Two fish speciesOreochroisniloticus and Cyprinuscarpio were observed. The aboundance of fish is higher in wet season than dry season.Oreochroisniloticus was found dominantrepresnting13.79%andCyprinuscarpiowas the least aboundant 6.895%.Regarding birds, a total of 8 species, 8 genera, 6 families and 4 orders were identified. The most abundant and frequent species were Egyptian Goose (42.80), Yellow-billed duck (38.14),Red billed duck (12.44) whereas spotted redshank (0.78) and Rouget’s rail (0.39) were the least abundant.The largest number of bird species was recorded indry season and the lowest in wet season. The Lake is under severe pressure due to anthropogenic activities, like population pressure, habitat destruction, deforestation, agriculture, siltation, water pollution, overgrazing, bird killedwith trap and unmanaged irrigation system all contribute to the decline of the bird and fish species in lake.It can be concluded that the fish and the bird diversity and aboundance were low in the area and nothing was done on biodiversity conservation. Hence, an urgent conservation measure is recommended.
