The audit overseen report written independent group ecologists, Independent Group (ISRAG). comprises Dr Peter Davies (Chairman), John Harris, Terry Hillman, Associate Professor Keith Walker. It main findings SRA Report 1: A Ecological Health Basin, 2004–2007. It also outlines nature ways that environmental data used assess health. How works: The gathers quantitative information indicators throughout provide ‘windows’ particular components eco­systems, grouped following themes: fish; macroinvertebrates; hydrology. Two more themes, vegetation physical form, will be added next due 2011. Future describe trends, showing how changes one next, over longer periods time. gathered systematically using agreed protocols, with quality assurance. Within Valley there four zones, defined most cases altitude. Sampling sites located randomly within enable unbiased statistical analyses representative reporting. combined form measures ‘condition’ theme, theme condition ratings Condition assessments valley related a benchmark called ‘reference condition’. This estimates status component (for example, fish community) as it would if had not been any significant human intervention landscape. Reference representing good health, but target management. rated five-point scale moderate, poor, very poor extremely depending different their respective benchmarks. same applied
