ABSTRACT
The phytosociological analysis carried in Samahni Valley and the vegetation was sampled by using quadrates of 10x2m, 5x2m and 0.5x0.5m for trees, shrubs and herbs respectively. Density, frequency and coverage of each species in the different stands were recorded. It was changed to relative scales and then added together to get the importance value for each species in each stand. Communities were named after the 3 leading dominants. The following five communities were recognized: (I) Melia-Lantana-Stellaria, (II) Morus-Dodonaea Melilotus, (III) Dodonaea-Grewia-Melia, (IV) Stellaria-Zizyphus-Dodonaea, (V) Oxalis-Pinus-Olea Communities. Index of diversity and its components decreased from low altitude to high altitude, but in Oxalis-Pinus-Olea community it was high. Soils were generally loamy, sandy loamy to clayey loamy type with pH varying from 7.0 to 7.6 organic matter 0.8 to 1.6%, Potassium 70.4 ppm to a 99.1 ppm and Phosphorous 5.46 ppm to 14.97 ppm. The communities reflect highly deteriorated condition.
