Abstract: In this study ecological risk analysis is applied for biotope potential of Gala Lake. The suitability and sensitivity of biotope potential against the present and planning uses are determined and then data is transferred to map. Suitability and sensitivity are evaluated together and ecological risk is determined then transferred to map. The most sensitive areas as regards biotope potential are determined as "Nature Conservation Area and Sites". Ecological risk; is "high" in Hisarli Mountain and the swamp areas, "medium/low" in agricultural fields.
