Using the Species–Area Relationship to Set Baseline Targets for Conservation

摘要: This paper demonstrates how the power form of Species-Area Relationship (SAR) can be used to set conservation targets for land classes using biodiversity survey data. The log-transformation model is a straight line; therefore, if one knows average number species recorded per site and estimate true present in class, EstimateS software, it possible calculate slope curve, or z-value. z-value exponent then proportion area required represent given any class. application SAR explored phytosociological releve data from South Africa's Succulent Karoo biome. We also provide suggestions extrapolating estimated z-values other within bioregion that lack sufficient data, relationship between remotely determined landscape variables such as habitat diversity (topographic diversity) geographic location (latitude longitude). predicts most vegetation types target 10% would not conserve majority species. demonstrate all are equal plant perspective, so applying region will lead significant gaps inefficiencies reserve network based on this universal target.
