Physico-Chemical Characteristics of water and Ornithological Assessment of Lake Telamine (Algeria)

Abstract

Our study aims is to highlight the importance of lake Telamine using two parameters : the ornithological assessment for estimate avian biodiversity and the evaluation of the water quality. First, we made censuses from December 2013 to May 2014. The census data revealed the presence of 30 bird species including one near-threatened species; ferruginous duck (Aythya nyroca) and threatened species; marbled duck (Marmaronetta angustirostris). In the second time we made study of the physical and chemical quality of the water, the organic pollution index (OPI) was used to evaluate the water quality and reveal that lake Telamine is characterized by a medium level of organic pollution but the level of BOD5 and the Orthophosphate still higher, This may be due to the presence of human activities around the lake and landfill in the middle of the lake.
