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一项紧迫任务。历史变异范围(RHV)理论提供了一个有影响力但在很大程度上未经检验的框架来指导修复活动。我们将检验RHV命题，即如果改变的生态系统的结构在定居前范围内恢复，生物多样性保护就会得到加强。植物、脊椎动物和无脊椎动物之间的比较？未恢复？Callitris林地以定居后再生长为主，并？恢复？站在RHV内再生减少的位置。这将是对RHV理论的第一次测试，以涵盖当地和景观尺度上的一系列分类学和功能群。

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.
