Check List is a peer-reviewed, open access, on-line journal devoted to publishing Notes on Geographic Distribution of one or a few species, and Distribution Summary of a taxonomic group. These data are essential for studies on biogeography and provide a baseline for the conservation of biodiversity as a whole. The first step to undertaking effective conservation action is to understand species’ geographic distribution. Check List was established to cater to this need by publishing papers on the geographic distribution of species and higher taxonomic groups.
