Abstract: Phytosocio logical analysis carried out in 53 stands, created in habitat of wintering Houbara in Balochistan, suggests presence of at least 90 species, appearing in different combinations in 21 communities distributed under different conditions of soil, temperature and altitudes. The constancy of appearance of most of the species is low (> 20% only for Rhazya stricta, Anabasis sp., Pennisetum dichotomum, Calligonum comosum and Haloxylon ammodendron). There is a good degree of intra-stand homogeneity and most of the stands have < I I species. Shrubs constitute the only regular layer, herbs appearing during some part of the year and no regular tree layer. Vegetation appears in patches. Vegetative cover ranges between 0.87 and 34.17 % but generally it ranges between I and 15%. Most of the species are vigorous, reproducing sexually and/or a sexually and exhibit different degree of xerophytic characters. The phenological cycle exhibited by different species can be explained on temperature and precipitation pattern.
