The original article incorrectly cites Hammer et al. 2004 in subsection ‘Land cover analysis’ of ‘Material and methods’. Where the text states ‘To account for the influence of forest disturbance and succession on range dynamics, we used a forest disturbance data set that maps all canopy disturbances that regenerated to forest in the region since 1990 [39]’.
