Central Mountain Range

Central Mountain Range. It is the principal mountain range and drainage divide of Taiwan, forming the island's rugged backbone. Stretching approximately 340 kilometers from Suao in the north to Hengchun Peninsula in the south, it encompasses some of East Asia's most dramatic topography. The range's formation is a direct result of the ongoing collision between the Philippine Sea Plate and the Eurasian Plate.

Geography and Geology

The range forms a continuous spine that separates the western alluvial plains from the narrower eastern coastal regions. Its geological structure is dominated by thick sequences of Tertiary metamorphic rock, primarily slate and schist, uplifted by the intense orogeny associated with the Taiwan orogeny. Major geological features include the Lishan Fault and the Chaochou Fault, which are significant tectonic boundaries. The range's rapid uplift, among the fastest in the world, is continuously studied by institutions like the Central Weather Bureau and Academia Sinica. This tectonic activity contributes to frequent seismicity, with major events like the 1999 Jiji earthquake originating from related fault systems.

Climate and Ecology

The range creates a profound rain shadow, with the windward eastern slopes receiving copious precipitation from the East Asian Monsoon and typhoons, while the leeward west is comparatively drier. This gradient supports a stunning altitudinal zonation of ecosystems, from tropical rainforests in the southern lowlands to alpine tundra on the highest summits. The range is a critical biodiversity hotspot, hosting endemic species like the Formosan black bear, Formosan sika deer, and Taiwan blue magpie. Its forests are composed of Chamaecyparis species, Taiwan red cypress, and ancient Taiwanese hemlock stands, forming part of the broader East Asian temperate forest biome.

Human History and Settlement

Historically, the formidable terrain limited large-scale Han Chinese settlement, allowing indigenous Austronesian peoples such as the Atayal, Bunun, Paiwan, and Rukai to maintain their cultures and territories. Significant historical trails, including the Southern Cross-Island Highway and remnants of the Qing dynasty's Mudan Incident-era paths, cross the range. During the Japanese colonial period, expeditions like those led by anthropologist Torii Ryūzō and logging operations began systematic exploration. Post-retrocession, infrastructure projects like the Central Cross-Island Highway and New Central Cross-Island Highway improved access, though many areas remain remote.

Major Peaks and Landmarks

The range contains most of Taiwan's highest peaks, collectively known as the Baiyue. The supreme summit is Yushan (Jade Mountain), the highest point in East Asia outside the Himalayas and the Kunlun Mountains. Other notable peaks include Xueshan (Snow Mountain), Syangshan, Mabolashe Mountain, and the Nanhu Dashan massif. Significant landmarks encompass the dramatic Taroko Gorge, carved by the Liwu River, the high-altitude Hehuan Mountain pass, and the scenic Qilai Peaks. These features are central to activities like the annual Yushan Trail Run and are celebrated in works by artists such as Guan Liang.

Conservation and Protected Areas

Large portions are protected within Taiwan's national park system, including Yushan National Park, Taroko National Park, Shei-Pa National Park, and the Maolin National Scenic Area. Conservation efforts focus on endemic species recovery, such as programs for the Formosan landlocked salmon in Chichiawan Stream, and combating threats from illegal logging and climate change. These areas are managed by the Ministry of the Interior's Construction and Planning Agency and are integral to UNESCO's tentative list for World Heritage Site consideration. Research stations like Fushan Botanical Garden and the Yushan National Park Headquarters facilitate ongoing scientific study and environmental education.
