Studying Some Ecological Properties of Sphaerocoma Aucheri in Hormozgan

Sphaerocoma aucheri is one of the most important genus of Hormozgan coastal regions. In this paper, at first, dispersion map was provided and then, the investigations have been done in 7 regions such as Pibeshk, Jask, Keryan, Divan, Hosseine and Chark from east to west of Hormozgan (about 700 Km from the first and the last searching site). This genus, with an extent about 23794 hectare in the coastal regions of Hormozgan with an altitude near the sea level in Qeshm island to the height of 100 meter from sea level in Chark Port, is being seen on the lands with a finetexture and on the stabilized sand hills. Based on the lands’ capability maps, this species is being seen in the lands’ units as 3.5, 8.1, 8.2 and X.2. Measuring the vegetative parameters in these regions indicate that the most percentage of coverage (vegetative coverage) in this plant and the least one are about 10.67% in Divan region and 2.05% in Hosseineh, respectively. Based on the density (number of stems/stalks in hectare), Chark with 11583 stalks is in the 1st place and Pibeshk with 2500 stalks is in the last place. And also the maximum density is about 60.39% in Divan region and the minimum one is about 13.23% in Hosseineh region.
