Moringa is one of the semi-tropical vegetation elements, distributed in the Sahara Sindian region, near the Dead Sea, Red Sea, Somalia, Saudi Arabia, Oman, UAE, Iran, and Pakistan. Moringa distribution in Iran is limited to the mountainous areas of Hormozgan and Baluchestan in Iran. Moringa is a chasmophyte species, growing well on fractured sandstone, shale, and schist. It grows in a warm and dry climate with no frozen period, a mean annual rainfall of 180-200 mm, a mean annual temperature of 26-27ºC, and a mean annual evapotranspiration of 3448 mm. The soil of habitat varies from shallow to very deep with different soil textures, a pH of 7.85 to 8.3, an electric conductivity of 1.36 to 4.5 ds/m, and no salinity limitation. This tree plays a key role in the local economy due to the various values including conservation, wildlife habitat, feed and fuel, beekeeping, nuts, edible oil, and medicinal and industrial uses. The seeds containing 53.9% oil, are traded at a price of $100/kg in the global market. The species is highly resistant to drought stress and able to adapt and expand in the Sahara Sindian region with minimal water requirements. Direct seeding and seedling methods using water storage systems like contour trenching, crop residues, and polyethylene sheets could be used for Moringa habitat restoration in the southeastern Iran.

Moringa peregrina is a tree or shrub, component of Nobo-Sindian district vegetation cover and extends from Dead seaSea and scatteresscatters in Red sea and spreads throughout northern Somalia and around the Arabian Peninsula to mouth of Persian Gulf and Iran. Its habitates in Iran are limited to Hormozgan and Sistan & Balochestan provinces onprovinces on mountainous andmountainous and foothilly foothill areas.
The habitat of Moringa M. peregrina is located in Sahara- Sindian climatic region with hot summer, moderate winter, mean rainfall of 180-200 mm, mean l temperature of 27ºC, mean evaporation of 3448 mm. Moringa often occupies Makran geological ranges and tertiary geology structural unit. Parent material consists of sandstone, shale and mudstone.
The results of soilof soil analysis showed that soil texture in most stands is sandy- loam, acidity is 7.98 and electricand electric conductivity is 1.78 des/m. The PCA results illustrated that the most important soil parameters for M. peregrina distribution were pH and sand valves respectively.
The results of stand properties showed the stands were coppice and density was weak and number of trees was 2-82/ha.
Distribution of M. peregrina around the Red sea, Golf of Adan and Oman sea on Montane region and the same bed rock are illustrated this tree as well as Acacia, Ziziphus spina-christi and Calotropis procera belongebelong to Tertiary period. In other word the presence of Moringa M. peregrina in Iran are is affected by geological revolution history¡ parent material, temperature, physiographic factors and soil properties.
