Species composition of the six vegetation units (I-VI) identified after the application of TWINSPAN to the vegetation data of 41 stands along the down-stream part of Wadi Gaza. The cover levels are coded as follows: 1, ≤ 10%; 2, 10-20%; 3, 20-30%; 4, 30-40%; 5, 40-50%; 6, 50-60%; 7, 60-70%; 8, 70-80%; 9, ≥ 90%. Vegetation units are: I: Arthrocnemum macrostachyum, II.

Centaurea ammocyanus - Atractylis carduus. life forms, except for the therophytes where the biregionals were highly represented (fig. 2). The Mediterranean components were the highest among the monoregionals (about 25 %) in most life forms, while the Mediterranean- Irano-Turanian were the highest among the biregionals (50 %) (table 1). Fig. 3. Relation between the six vegetation units resulting from DCA application. The eigen values for DCA of axis 1 was 0.763 and for axis 2 was 0.581. Vegetation units are: VGI: Arthrocnemum macrostachyum; VGII: Mesembryanthemum crystallinum; VGIII: Tamarix nilotica – Arundo donax; VGIV: Tamarix nilotica; VGV: Alhagi graecorum - Xanthium spinosum; VGVI: Centaurea ammocyanus.- Atractylis carduus. 2 11 00 00000 11111111 1111111111111 00000000000 3 11 00000 11111111 0000000000000 11111111111 4 01111 00000111 0000111111111 0111111111 5 00001 000000001 000000111 6 00000001 011111 TWINSPAN divided the set of 41 stands into six vegetation units at level 3. They are named after the characteristic species (which had highest values of presence percentage and/or cover percentage) as follows: Arthrocnemum macrostachyum (I), Mesembryanthemum crystallinum (II), Tamarix nilotica – Arundo donax (III), ecologia mediterranea, tome 29, fascicule 2, 2003
