摘要：Potapov et al. (2008) provide a useful data set that applies to understanding intactness at a global scale,and roughly, how intactness differs from one continent or country to another. However, we caution againstusing these data for applied conservation analyses at scales finer than the earth as a whole, particularly ingeographies with socioecological realities that differ markedly from those in Russia (the home region ofPotapov and most of his co-authors). This caution stems from what may be an irresolvable scale-relatedissue in using global data for country-specific analyses. A suite of assumptions that are judicious for onegeography can introduce large errors in other parts of the world with different socioecological forcesdetermining where intact landscapes remain
