坦桑尼亚的东弧山脉显示出特殊的特有物种，受到高人为压力的威胁，导致自然栖息地的丧失。本文利用一种新的生境转换模型，对东方弧25年来森林和林地转换的预测因子进行了空间显式分析。结果表明，1975 - 2000年，东弧山区常绿森林面积减少了5% (210 km(2))，森林面积减少了43% （2060 km(2)）。生境转换的重要预测因子包括与自然生境边缘的距离、地形和偏远程度。在过去的100年里，这些山区的主要保护策略是建立一个保护区网络。这些措施似乎降低了栖息地丧失的速度，大多数剩余的常绿森林现在都在保护区内。然而，作为生态系统服务的重要来源，大多数miombo林地位于正式保护区之外，可能需要额外的保护策略。(C) 2013 Elsevier Ltd.版权所有。
The Eastern Arc Mountains of Tanzania show exceptional endemism that is threatened by high anthropogenic pressure leading to the loss of natural habitat. Using a novel habitat conversion model, we present a spatially explicit analysis of the predictors of forest and woodland conversion in the Eastern Arc over 25 years. Our results show that 5% (210 km(2)) of evergreen forest and 43% (2060 km(2)) of miombo woodland was lost in the Eastern Arc Mountains between 1975 and 2000. Important predictors of habitat conversion included distance to natural habitat edge, topography and measures of remoteness. The main conservation strategy in these mountains for the past 100 years has been to develop a network of protected areas. These appear to have reduced rates of habitat loss and most remaining evergreen forest is now within protected areas. However, the majority of miombo woodland, an important source of ecosystem services, lies outside formal protected areas, where additional conservation strategies may be needed.
