The range of geographical and climatic regions has led to a diverse variety of flora and fauna with in this region. These parts of area are heavily cultivated and the landscape, therefore, largely consists of terraced paddy fields and rolling hills. The area is also famous for its winter crops of oranges, which can be purchased fresh from the trees along the trails in the foothills. As you progress higher up into the hills the natural vegetation changes from the tropical species to more temperate stands of forest trees including oak, beech and rhododendron. These finally give way to coniferous forests of pine and, ultimately, juniper just below the tree line. In the rain shadow, to the north of the mountains, the landscape is quite barren being an extension south of the Tibetan plateau.
