Forestry effects on headwater ecosystem health: a multi-catchment experiment

澳大利亚南部的大部分集水区都有历史记录。越来越多的原生森林采伐发生在再生长区或干旱地区。虽然林农有关于在原始或湿润的集水区采伐的生态影响的经验数据，但在干旱的再生地区却很少，这妨碍了有效的管理，以尽量减少对河流生态系统健康的影响。该项目将提供河流生态系统的生态数据，以补充新南威尔士州森林从5个实验集水区收集的4年水文数据。研究结果将为该森林类型的生态可持续采伐提供更坚实的科学依据，为我国国民经济、生物多样性和环境带来源源不断的效益。

Most catchments in southern Australia have been logged historically. Increasingly, native forest harvesting occurs in regrowth or drier areas. Although foresters have empirical data on ecological effects of harvesting in pristine or wetter catchments, little exists for drier regrowth areas, hampering effective management to minimize impacts on stream ecosystem health. This project will supply ecological data on stream ecosystems to supplement 4 years of hydrological data collected by Forests NSW from 5 experimental catchments. Results will provide a firmer scientific basis for ecologically sustainable harvesting in this forest type, with flow-on benefits to our national economy, biodiversity, and environment.
