 Distribution maps should be very cautiously looked at. They do not provide with precise location but only give an idea of species global distribution. Distribution areas are geopolitical; as a consequence the whole of a country is selected if a species is only located in one single place. For more precise distribution areas please go to IUCN site (see link above).
