Prior to Māori arrival, New Zealand was almost entirely forested, besides high alpine regions and those areas affected by volcanic activity. Māori began settling the country about 1000 years ago [3] and by 1840, when Europeans were a small part of the total population, the forest cover was significantly reduced from 85% down to 53%.
Forestry in New Zealand has a history starting with European settlement in the 19th century and is now an industry worth seven percent [citation needed] of annual revenue. 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.
New Zealand has thirteen national parks, forty four marine reserves and many other protected areas for the conservation of biodiversity.The introduction of many invasive species is threatening the indigenous biodiversity, since the geographical isolation of New Zealand led to the evolution of plants and animals that did not have traits to protect against predation.
Half of the area experiencing deforestation consists of new forests or forest growth. In addition to direct human-induced deforestation, growing forests have also been affected by climate change . The Kyoto Protocol includes an agreement to prevent deforestation, but does not stipulate actions to fulfil it.
New Zealand's forest ecosystems for example are being considered as the second most endangered of the world, with only 7% of the natural habitat remaining. [12] A male brown kiwi. Eighty per cent of New Zealand's biota is endemic. New Zealand's biodiversity exhibits high levels of endemism, both in its flora and fauna.
English: In this paper we afford a quantitative analysis of the sustainability of current world population growth in relation to the parallel deforestation process adopting a statistical point of view. We consider a simplified model based on a stochastic growth process driven by a continuous time random walk, which depicts the technological ...
