摘要:AbstractKaz Mountain (Mt Ida), with an elevation of 1774 meters, is the highest landform on the Biga peninsula located in the northwest of Turkey. This mountainous area is situated on the transition zone between the Mediterranean and Black Sea climates. Thus, it has ecologically interesting features. The purpose of this study is to explain the ecogeographical features of the ecosystem of Kaz Mountain. To that end, all physical features such as geomorphological, geological, climate, soil, hydrographical, vegetation, and fauna features were examined. The data obtained was compiled and classified. Hence, ecogeographical features of the area were revealed. Some parts of Kaz mountains were previously declared a national park for the purpose of protection. However, the national park does not cover all of the mountainous mass. The population pressure on the area is constantly increasing. For this reason, national park boundaries should be expanded to protect the whole ecosystem.
