在南部，西高止山脉的南与其他小的山脉相连，特别是泰米尔纳德邦西北部的尼尔吉里丘陵。这些小山脉和丘陵与东高止山脉相连接，起到野生动物走廊的作用，通过此走廊，大象等动物可以在西边和西边的山脉之间自由穿梭。

The Western Ghats or Sahyadri is a mountain range that runs parallel to the western coast of the Indian peninsula, located entirely in India. It is a UNESCO World Heritage Site and is one of the eight "hottest hotspots" of biological diversity in the world. It is sometimes called the Great Escarpment of India. The range runs north to south along the western edge of the Deccan Plateau, and separates the plateau from a narrow coastal plain, called Konkan, along the Arabian Sea. A total of thirty nine properties including national parks, wildlife sanctuaries and reserve forests were designated as world heritage sites - twenty in Kerala, ten in Karnataka, five in Tamil Nadu and four in Maharashtra.
