Coastlines in subtropical areas especially coastal habitats are subjected to oil pollution due to all kinds of oil industries and transportation accidents. Recent studies have focused on long term period times effects like biological and chemical response and reaction of ecosystems. Since mangroves are one of the main important species which have vital role in ecological process in the coastal habitats. In this research short term periods response of Avicenna marina’s pneumatophores as one of substantial parts of mangroves has been considered facing the oil slick in tidal waves in two seasons. Field experiments carried out in winter and summer regarding to wing and temperature thresholds and industrial activities. Experiments are supposed to be a kind of natural physical model of some oil spill disaster which after 24 hours the oil slick reach to the coastal habitats. Weathered oil released to designed experimental plots and sampling and laboratory analysis were carried out after treatments. Results showed that the physical adsorption in short term period in the winter is more than spring generally. Some suggestions were put forwarded following the results which can lead us to some hypothesis on short effects of oil slick in different seasons or different climate. The conclusions would be useful for coastal environment protection guards in oil spill disaster management.
