The species of Sphaerocoma aucheri Boiss. It is one of the important desert species in the coastal sand dunes of Hormozgan province, which plays a significant role in soil conservation in the region. The present study was conducted to investigate the biological changes of this species in the longitudinal profile of the distance from the sea on the sandy beaches of Bandar Charak county. First, representative areas were selected and then 4 transects were placed perpendicular to each other in each representative area. In each transect, 4 m2 plots were placed at 100m intervals and vegetative parameters were measured. On each transect, three soil samples were prepared from a depth of zero to 30 cm and the parameters Sp, EC, pH, T.N.V, Gyps, OC, N, Ca+Mg, Na, SAR, clay, silt and sand were measured. The results showed that the highest amount of sand was measured in the stand near the sea (87.8%), and the highest amount of clay (13.8%). According to the results, since the soil in the distribution areas of this species was all light with sandy and sandy loamy texture, and considering the measured SAR of 1.5-9.8 meq/lit and 1.597-2.192 mmos/cm, the soil in the distribution areas of the species is considered non-saline. With distance from the sea, the parameters of the percentage of coverage, height, and diameter of the plant canopy began to decrease, which is due to the decrease in the humidity of the air or humidity and the heaviness of the soil in the habitat. Given the palatable nature of this species for livestock, and its value as a natural cover as a natural mulch or living mulch, it is recommended that this plant be planted in sandy areas under wind erosion crisis in the southern part of the country.
