Description
Summary:	We assessed the expected historical and current speciesrichness of shrubs and trees in the Department of Antioquia,northwest region of Colombia. We used the Fisher´s alpha valueassociated with the pooled dataset of identified species in 16 1-haplots that were used to extrapolate the scaled species richness ofthe Antioquia Province under three different scenarios: 1) the entireregion before deforestation began, assuming an original forestcover of around 92% of the entire province (excluding paramos,rivers, and lakes). 2) The forest cover in 2010. 3) The expected forestcover in 2100 assuming the observed deforestation rate between2000 and 2010 as a constant. We found that, despite relativelylow local and global losses of species, global extinctions in termsof number of species could be dramatically high due to the highendemism and deforestation rates.
