Kucukcekmece, is one of the important districts to define the city of Istanbul at the international level with its historical, cultural, and natural values. In this study, the parks in Kucukcekmece District were examined in terms of ecological quality, principles, and standards. Ecological quality is a composite of the structural and functional features determining the habitat values of a landscape. An objective evaluation on the ecological quality of parks is important from the point of rehabilitation from an existing situation, and providing areas which will have high habitat value in the future. Recovery in the existing park area will generate a livable urban atmosphere. In line with this basic comprehension, the ecological quality of the parks in Istanbul's Kucukcekmece District was examined. There are four principles determining ecological quality of an area: vegetative production, water, permeability (soil), and natural vegetation cover (biological diversity). This research was done in two phases regarding the permeability and natural vegetation cover using ecological quality principles.
