摘要:Using the historical range of forest conditions as a reference for managing landscapes has been proposedas a coarse-filter approach to biodiversity conservation. By emulating historical disturbance processes, it is thoughtthat forest management can produce forest composition and structure similar to the conditions that once supportedthe native biota. A recent project was designed to integrate social and ecological findings to investigate the importantrelationships between the state of ecological understanding of a region, the state of the region's biodiversity, and thestate of the region's social understanding of how it might be managed for biodiversity conservation into the future.The project relied on established concepts of the historical range of variability (HRV) and developed the concept ofthe social range of variability to help explain the interaction of social and ecological assessments, particularly theirinteraction to create future ranges of variability. The Oregon Coast Range, where a rich history of HRV research hasbeen completed starting with paleoecological reconstructions of the historical fire regime, was one of five sites inthe United States that were selected as case studies. We found land development and impending climate change tobe major hurdles impeding the use of the HRV as a management regime. We also found that the complexities anduncertainties of management preclude the use of any single tool to tackle landscape-scale challenges and suggestthat land management needs to become a continuous process of negotiation
