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).
