Nowadays, due to climate change and drying of Urmia Lake, and the recession of water, a number of vegetation communities have disappeared and other communities have emerged. Alhagi pseudalhagi has also been degraded by extensive ecological, habitat, anatomical, morphological, physiological, genetic and biological properties, and has been dispersed along the border with agricultural soils, which, in the absence of management, agricultural land will be compromised. Therefore, based on climate change and the urgent need to provide part of forage from less-water efficient, not common and, salt and drought-resistant it can be stated that the most important application of Alhagi pseudalhagi is forage. . However, there is no report on the grazing of Alhagi pseudalhagi by the dominant livest of region which is native cattle and buffaloes. Hence, the best way to deal with it is to graze various livestock and targeted grazing from its breeding grounds. This method can restore the equilibrium to the ecosystem, in which a more balanced utilization of all the halophytic species of the margin of the lake can be considered.  The camel's grazing in the degraded lands will be able to control the growth of seed production and, to a large extent, the spread of pests and disease. Considering all the factors affecting the profitability of gazing camel, it can be say that the pasture cultivation is an effective remedy for deficiency of forage. In fact, their potential contribution to preventing livestock losses in the non-growing season is their most important advantage. In addition, there are other benefits such as oil production, bio-ethanol, aromatic compounds, vegetarian manna, honey production, and so on. Therefore, its cultivation in saline pastures and direct grazing of livestock from them are recommended. Hence, the creation of artificial pasture requires further research on the pattern sites and a low risk for biodiversity in rangelands.

The extensive lowland of Khuzistan in SW.Iran, with halophytes vegetation has been studied floristically. Brief information on the climate, lithology and habitat of the area are presented. The hot desert of lowland of the Persian Gulf area with complex floristic situation is described. Their phytogeographical and taxonomic relationships are discussed in detail and attempts are made to relate the distributional patterns to certain ecological factors. 22.6% of species are Irano- Turanian & Saharo - Sindian; 20% Sah-Sin & Ir.-Tur. & Mediterranean; 13.6% cosmopolitan; 11.8% SaharoSindian; 7.9% Pluriregional; 6.8% Paleotropic; 5% Ir. Tur. & Medi.; 5% Sah.-Sin. & Medi.; 3-8% Omni-Sindian and 3.5% Irano-Turanian. Further aspects pointed out are the representation of life form of families and genera and their enviroment
