Abstract

The names given to places are a legacy of the past distribution of animal and plant species. The hypothesis tested in this work is that the density of toponyms can be used to predict the range of two large and charismatic species over time: the wolf and the brown bear in Italy. Kernel density maps of the toponyms were created and different thresholds of density were overlapped with the present and the historical ranges for both species. The density level maps were tested with the Kappa statistics against available historical ranges for both species. The pattern of the density in toponyms overlapped with the pattern of contraction and expansion reported in literature for both species over time. The minimum historical distributions of wolves and brown bears occurred at the highest densities of toponyms (95% isopleth value) and, overall, the various kernels thresholds showed an excellent agreement with the historical maps with an average Kappa of 0.84 ± 0.5.
