This paper deal with the Agal Vegetation of seashores of Qeshm island. the important aims of the investgation including identification of: (A)- Algal distribution B) Ecological factores like Temperatures, Humidity, Rain fall, Tidal, information time of sun shine, Nutrient elements, PH, Alkality, salinity and substratum. (C)- vegetation characteristic including: percentage of cover, species diversity, zonation, Imigration and depth effects on Algal vegetation. Environmental observatiln mapping of vegetative area drawing of selective stations profile, measurment of Environmental factores and registration of transect and quadrat information were done between 1372- 1375. Analysis of information showing Tidal regims, Temprature, Humidity and nutrietional elements are important factors which directly and Nutrietional elements are important factors which directly and idirectly effect on vegetation characteristics.
