The study area The Nile Delta is a classic delta with a triangular shape situated in North Egypt where the Nile River spreads out and drains into the Mediterranean Sea. The emerging landscape classifications are based on the use of GIS and statistics in order to map landscapes, evaluate their character and apply the framework for decision making and planning.

The bagmouls was used to identify these landscape units that should be targeted with conservation measures.

Looking at phenological stages rather than species presence and absence only, a continuous course of turnover with an increase at the end of the vegetation period could be observed. Occurrences of early species Isoetes histrix, Scirpus pseudosetaceus, Juncus hybridus, Juncus capitatus and Radiola linoides were used to select suitable sites for the study.
