Range maps
Before using species range maps for any purpose, we urge you to exercise caution and be aware of potential limitations and challenges associated with their interpretation. While we have made efforts to create the most up-to-date range maps by synthesizing diverse data sources, including historical published range maps, occurrence data from natural history specimens, field guides, peer-reviewed published research, and personal communication with experts, these data may have varying degrees of accuracy and reliability, leading to potential inaccuracies and gaps in the representation of a species' distribution. For some species, data may be scarce or biased toward easily accessible areas, resulting in incomplete representation of their true range. Taxonomic revisions can affect species identification and may not be immediately reflected in range maps, potentially leading to misinterpretation. Exercise prudence in the application of these maps and acknowledge their limitations to make informed decisions for conservation, research, species identification, and project planning.
