Abstract

Aim: The aim of the study was to analyze biotopes sensitivity in Samandağ coastal zone in Mediterranean coastal region of Turkey. The study was carried out to map the biotopes using object-oriented classification and to determine sensitivity of these biotopes using rareness and re-establishment ability.

Methodology: The study was performed with the help of remote sensing and geographic information system in three stages, i.e., obtaining data, creating map of biotopes using object-oriented classification using ALOS AVNIR imagery assisted with field verification and determination of biotope sensitivity to human disturbance. The sensitivity assessment was based on two parameters, i.e., rareness and re-establishment ability of biotopes.

Results: As a result of classification, biotope types were divided as cultural areas and semi-natural areas. Cultural areas; commercial area, settlement (garden houses, multi-story), protected area, agriculture (annual), horticulture, semi-natural areas; forest, bare rock, coastal dunes, dry streambed, river banks, meadow, shrubs, wetland meadow. The results showed that the majority of biotopes in Samandağ coastal zone were either very sensitive or sensitive to human disturbance. Agricultural activities and construction on the coastal zone have threatened the wildlife, especially species of Caretta caretta and Chelonia mydas and some of the endangered plants.

Interpretation: The wise use of coastal resources and reduction of anthropogenic pressure is possible through planning based on ecological data integrated of social and economic system. only the comprehensive plan of action could help to protect these dunes.
