The study presents the results of a field investigation of the crocodile nesting sites on Lake Nasser, observed during the breeding season 2009-2010. A relatively low number of nesting sites was found, explained by the intensity of anthropogenic activity in the area and by the low water levels of Lake Nasser. Based on analysis of satellite imaging and its correlation with the biotope data of the lake shores, a classification system of habitats and of their suitability for crocodile nesting was established. Correlated with land use information, the results can lead to the identification of potential nesting sites for the Nile crocodile, establishing a legal protection system for such habitats.
