42 u Y. M. AL-SODANY METHODS Eleven stands each of 100 x 200 m were selected along N-S transect in the study area to represent the environmental variations of five major habitats that associated with the distribution of 15 common shrubby species (table 1). These species are: 3 phanerophytes (Lycium europaeum, Phlomis floccosa and Thymelaea hirsuta) and 12 chamaephytes (Anabasis articulata, Artemisia herba-alba, Artemisia monosperma,Arthrocnemum macrostachyum Deverra tortuosa, Echiochilon fruticosum, Gymnocarpos decander, Halocnemum strobilaceum, Helianthemum lippii, Limoniastrum monopetalum and Noaea mucronata and Suaeda vera).The population structure of these species was evaluated in terms of size distribution. For achieving this, the height and mean crown diameter of each individual in the whole stand was measured (based on 2-4 diameter measurements / ind.) and its volume was calculated as a cylinder.The volume estimates were then used to classify population into 9 size classes: the first (
