The extent to which climate change might diminish the efficacy of protected areas is one of the most pressing conservation questions. Many projections suggest that climate-driven species distribution shifts will leave protected areas impoverished and species inadequately protected while other evidence suggests that intact ecosystems within protected areas will be resilient to change. Here, we tackle this problem empirically. We show how recent changes in distribution of 139 Tanzanian savannah bird species are linked to climate change, protected area status and land degradation. We provide the first evidence of climate-driven range shifts for an African bird community. Our results suggest that the continued maintenance of existing protected areas is an appropriate conservation response to the challenge of climate and environmental change.
气候变化可能降低保护区效力的程度是最紧迫的保护问题之一。许多预测表明，受气候驱动的物种分布变化将使保护区内物种匮乏，保护不足，而其他证据表明，保护区内完整的生态系统将能够适应变化。在这里，我们通过实证研究来解决这个问题。我们展示了坦桑尼亚 139 种热带草原鸟类最近的分布变化如何与气候变化、保护区地位和土地退化有关。我们首次提供了非洲鸟类群落受气候驱动的分布范围变化的证据。我们的研究结果表明，继续维持现有的保护区是应对气候和环境变化挑战的适当保护对策。
