Fig 9. Species distribution model accuracy with and without data submission scores (AUC a and Kappa b.).

There are 20 species models from each of the 6 BCRs: 10 for species, which are hard to identify, and 10 for species that are easier to identify, as defined by differences between the highest and lowest quartiles of data submission scores (Figs 6 and 7). In most cases the inclusion individual observer data submission scores improved model accuracy.
