Much of the original native forest cover was burnt off and logged, however forests have been extensively planted, predominantly with fast-growing cultivars of the Monterey Pine. Wood chips, whole logs, lumber and paper products are exported from New Zealand. Deforestation in New Zealand on public land attracted opposition with protests and environmental groups becoming very active until it ended in 2000. Logging of native forests now only occurs on private land if it is shown to be sustainable. ==History== Milling of New Zealand's extensive native forests was one of the earliest industries in the European settlement of the country. The long, straight hardwood from the kauri was ideal for ship masts and spars. As the new colony was established, timber was the most common building material, and vast areas of native forest were cleared. Rimu, tōtara, matai, and miro were the favoured timbers. The Monterey Pine, ''Pinus radiata'' was introduced to New Zealand in the 1850s.〔New Zealand Official yearbook, 1990〕 It thrived in the conditions, reaching maturity in 28 years, much faster than in its native California. It was found to grow well in the infertile acidic soil of the volcanic plateau, where attempts at agriculture had failed. Thomas William Adams experimented with ''P. radiata'' and other trees in Canterbury from the 1870s, and promoted the early forestry industry. The Government initiated planting of exotic forests in 1899 at Whakarewarewa, near Rotorua. This was to address growing timber shortages as slow-growing native forests were exhausted. In the 1930s, vast areas of land were planted in pinus ratiata by relief workers. The largest tract was the 188,000-hectare Kāingaroa forest, the largest plantation forest in the world. As the major forests matured, processing industries such as the Kinleith Mill at Tokoroa and the Tasman Mill at Kawerau were established. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Forestry in New Zealand」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
