The density of georeferenced data varies widely among subregions - The South American subregion lags behind, but important efforts are getting underway. [...] Not having access to all biodiversity data, in addition to hindering research progress, introduces uncertainty in the results of regional and global-scale studies that rely heavily on occurrence data and lowers the quality of environmental impact studies within countries;- Where available, the information is limited to a few groups of better-known organisms and does not necessarily coincide with the spatial delineation of the World Wildlife Fund terrestrial biomes adopted by the assessment - Although many formally accredited sites are found in the Americas, these are strongly concentrated in the USA, Mexico, and Brazil;- Two major challenges for the future in the Americas are to standardize information and to make it available in a template that is usable by decision makers.
