VI scores and expert assessments of 111 box gum grassy woodland sites

Dataset to support "<b>Does the NSW Vegetation Integrity assessment underestimate the conservation values of derived native grasslands?</b>".Data for 111 Critically Endangered Box-gum grassy woodlands (BGGW) and associated DNG sites. VI scores are derived using the geometric mean of Composition, Structure, and Function sub-indices (V__Geometric, the default VI metric) which is contrasted with three alternatives: (1) the arithmetic mean of Composition, Structure, and Function (VI_Arithmetic); (2) the geometric mean calculated after applying a minimum value of 10 for Function (VI_Function_min10); and (3) using a grassland vegetation class benchmark (VI_Grassland_BM).

本数据集用于支撑《新南威尔士州（New South Wales, NSW）植被完整性评估是否低估了衍生原生草原的保护价值？》相关研究。数据集包含111个极危盒树草原林地（Box-gum grassy woodlands, BGGW）及相关衍生原生草原（derived native grasslands, DNG）样地的相关数据。植被完整性（Vegetation Integrity, VI）分值通过组成、结构与功能子指数的几何平均值计算得到（即V__Geometric，默认VI评估指标），并与三种替代计算方案开展对比：（1）组成、结构与功能子指数的算术平均值（VI_Arithmetic）；（2）对功能子指数设置最小值10后再计算几何平均值（VI_Function_min10）；（3）采用草原植被类群基准值进行计算（VI_Grassland_BM）。
