year. Intensive rain from typhoons often leads to disastrous mudslides. Records Climate change Flora and fauna Before extensive human settlement, the vegetation on Taiwan ranged from tropical rainforest in the lowlands through temperate forests, boreal forest and alpine plants with increasing altitude. Most of the plains and low-lying hills of the west and north of the island have been cleared for agricultural use since the arrival of the Chinese immigrants during the 17th and 18th century. However the mountain forests are very diverse, with several endemic species such as Formosan cypress (Chamaecyparis formosensis) and Taiwan fir (Abies kawakamii), while the camphor laurel (Cinnamomum camphora) was once also widespread at lower altitudes. Taiwan is a center of bird endemism (see List of endemic birds of Taiwan). Prior to the country's industrialization, the mountainous areas held several endemic animal species and subspecies, such as the Swinhoe's pheasant (Lophura swinhoii), Taiwan blue magpie (Urocissa caerulea), the Formosan sika deer (Cervus nippon taiwanensis or Cervus nippon taiouanus) and the Formosan landlocked salmon (Oncorhynchus masou formosanus). A few of these are now extinct, and many others have been designated endangered species. Taiwan has 65 species of fireflies, the third highest density after Jamaica and Costa Rica. Fireflies are protected and their numbers are increasing but in the long term they are threatened by climate change. Taiwan had relatively few carnivores, 11 species in total, of which the Formosan clouded leopard is likely extinct and the otter restricted to Kinmen island. The largest carnivore is the Formosan black bear (Selanarctos thibetanus formosanus), a rare and endangered species. Nine national parks in Taiwan showcase the diverse terrain, flora and fauna of the archipelago. Kenting National Park on the southern tip of Taiwan contains uplifted coral reefs, moist tropical forest and marine ecosystems. Yushan National Park has alpine terrain, mountain ecology, forest types that vary with altitude, and remains of ancient road. Yangmingshan National Park has volcanic geology, hot springs, waterfalls, and forest. Taroko National Park has marble canyon, cliff, and fold mountains. Shei-Pa National Park has alpine ecosystems, geological terrain, and valley streams. Kinmen National Park has lakes, wetlands, coastal topography, flora and fauna-shaped island. Dongsha Atoll National Park has the Pratas reef atolls for integrity, a unique marine ecology, biodiversity, and is a key habitat for the marine resources of the South China Sea and Taiwan Strait. Natural resources Natural resources on the islands include small
