Abstract

(1) This study reports on an ecological survey of the main parts of the Eastern Desert of Egypt. This is divided on geographical (climate, lithology, latitude, etc.) bases into three regions. (2) The general attributes of desert vegetation as represented in the surveyed area are given. (3) Eighteen community types are recognized. Some are confined to one of the three regions, others are recorded in two or three regions. Widespread community types show regional variations in their floristic composition that allow for recognition of regional facies of these types. (4) Classification of vegetational units on grounds of structure and growth form of dominant species shows close relationships between these characters and the habitat complex.
