Refining Restoration Ecology: Is Range of Historical Variability an appropriate concept to guide ecosystem management and restoration?

生态系统恢复是澳大利亚许多景观的紧迫任务。历史变异性范围（RHV）理论为指导恢复活动提供了一个有影响力但在很大程度上未经检验的框架。我们将测试RHV的命题，即如果改变的生态系统结构在预定居范围内得到恢复，生物多样性保护将得到加强。植物、脊椎动物和无脊椎动物将在未恢复的？calitris林地以聚落后再生长为主，且已恢复。站在RHV内再生减少的地方。这将是RHV理论第一次在本地和景观尺度上涵盖一系列分类和功能群的测试。

Ecosystem restoration is an urgent task in many Australian landscapes. Range of Historical Variability (RHV) theory provides an influential but largely untested framework to guide restoration activities. We will test the RHV proposition that biodiversity conservation is enhanced if the structure of altered ecosystems is restored within the pre-settlement range. Plants, vertebrates and invertebrates will be compared between ?unrestored? Callitris woodlands dominated by post-settlement regrowth, and ?restored? stands where regrowth has been reduced within the RHV. This will be the first test of RHV theory to encompass a range of taxonomic and functional groups at both local and landscape scales.
