Terrestrial Vertebrates Terrestrial Vertebrates Introduction P redicted species distributions are based on existing range maps and other distributional data gathered from state and federal cooperators, combined with information on the habitat affinities of each species. Distribution maps for individual species are overlaid in the GIS to produce maps of species richness, which can be created for any group of species of biological or political interest.
Gap analysis uses vegetation types and terrestrial vertebrate species as indicators of biodiversity.
The Arkansas Gap Analysis project will be completed for 457 terrestrial vertebrate species.
