Abstract
Along the coast of Egypt there are five lagoons. These lagoons (Maryut, Idku, Brullus, Manzala and Bardawil) constitute up to 50 to 70 percent of the Egyptian coastline and therefore are of major concern for any future shoreline management program. On addition, these lagoons have great economic value since they act as harbors for fishing boats and play a significant role in the regional economy and the international picture (El-Lakany, 1997)(1).
During winter and spring, the lagoons are sanctuary for hundreds thousands of birds, profiting from the rich aquatic resources. So, these lagoons have been recognized to be important wetland areas providing passage and wintering grounds for migrating birds. The Egyptian government officially acknowledges this by listing of two lagoons, Brullus and Bardawil lagoons, under the RAMSAR convention (International Convention on Wetland, important especially for waterfowl). In addition, the delta lagoons are internationally renowned for their „ abundant bird life. About one million hectares of natural or semi-natural wetland remain in the Mediterranean region, of which at least 280,000 hectares of coastal wetland are in north Egypt and Sinai. This means that over 25 % of all Mediterranean wetland are situated in along the Mediterranean coast of Egypt (El-Lakany, 1997)(1).
