Abstract
The major concern of this study is to throw light on the ecology and sustainable development of the northern delta lakes( Manzala, Burullus and Idku).sixty sites were chosen (20 sites in each lake) for studying the physicochemical characteristics of the water and sediment, aquatic vegetation, heavy metals in the aquatic plants, epiphytes on the aquatic plants, bottom fauna, fish diversity and birds diversity. On the other hand, 20 sites at islands of each lakes were selected for studying the vegetation analysis. Also 60 sites on the shores of the lakes were studied for their vegetation in different habitats. Soil seed banks were studied in three transects in lakes shores. The results elucidate the following: 1 Lake Burullus is considered as the cleanest lake in the deltaic lakes. 2 aquatic plants can be used bioremoval of heavy metals from water and so it can be used in the biocontrol of water pollution. 3 the bottom fauna can be used as habitat indicators and for monitoring the pollution in the northern lakes. 4 the epiphytic algae and fauna can used for monitoring pollution in the northern lakes. 5 45 bird species were recorded in the northern lakes and 23 fish species. 6Asustainable management plan for the northern delta lakes was constructed for conserve the biodiversity wealth of these vital lakes by using some aquatic plants for water treatment and prevent the illegal fishing , birds hunting, discharge of the polluted water into these lakes.
