Namibia's environment and tourism ministry, however, claims that there are 600 desert elephants left, and that the desert population is no different from the country's other groups of African elephants. So, no big deal.
But conservationists--and scientists--disagree, as John Platt writes at Scientific American:
Desert elephants, which can only be found in Namibia and Mali, are not a separate species or subspecies. They are, however, uniquely adapted to their arid environments. The animals have a few morphological differences from savanna elephants (Loxodonta africana), most notably their thinner bodies and wider feet. They also possess a number of unique behaviors shared by no other African elephants, such as digging wells to purify their drinking water. Tourists routinely travel to Namibia to volunteer in the elephants’ conservation.
The first of these permits was already executed, when hunters shot a "virile young male elephant" on June 21.
