Remnant Rarity Index (RRI)

资源简介：
The Remnant Rarity Index (RRI) describes the proportion of each NVIS major vegetation group remaining in each IBRA bioregion relative to the 1750 estimates. This approach is conceptually similar to biological status of ecological vegetation communities (EVCs) in Victoria and the biodiversity status of remnant regional ecosystems in Queensland. The RRI is therefore useful as a simple proxy for conservation status for analyses that cross jurisdictional boundaries. The RRI is solely dependent upon the difference between pre-1750 and extant vegetation mapping and does not consider additional processes such as land degradation or threatening processes.
