Abstract
Mangrove forests are important in Iran. The results of this research could be an important basis for the understanding of the situation facing the mangrove forest and improve the management and conservation of mangrove forests. In this study, Promethee II, a multiple criteria decision making method, was used to identify and rank the causes of deforestation. Ranking of natural causes of mangrove forest deforestation showed, Pests weight as the most important factor is 0/17 and after that the storm and acid rain weights are next in rank, 0.20 and 0.095 respectively. The results showed that the weight of the human causes of deforestation is more than five times of the weight of the natural causes of deforestation. In the case of human causes of deforestation weight of the oil pollution as the most important factor is 0.226. And after that the industrial and municipal waste, the development of ports and docks, no environmental assessment of projects, poor performance in the field of promotion, lopping for fodder, aquaculture and fuel weights are next in rank,0.19, 0.182, 0.136, 0.128, 0.082, 0.043 and 0.041 respectively. The results showed that the main deforestation causes of mangrove forests in Iran are oil and industrial pollution and urban waste. Since mangrove forests are located in the massive oil and gas reserves and projects, the extraction, conversion and transport of resources and urban development without considering environmental assessments have an adverse effect on the mangrove ecosystems.
