Review of science-based assessments of species vulnerability
... Overall species vulnerability is based on a score against 21 criteria divided into two categories: (1) response to climate change and (2) species-specific sensitivity. First, species response to climate change is assessed by using a numerical score that represents a documented change in (1) distribu ...
