Vast white salt flats crack and shimmer beneath a sun that pushes temperatures past 42 degrees Celsius. Gravel plains stretch to every horizon, interrupted only by dunes that shift with winds funneled between distant mountain walls. This is the Central Persian desert basins -- a landlocked ecoregion covering much of the Iranian Plateau, where no river reaches the sea and water that enters simply vanishes into salt. Walled in by some of Asia's great mountain ranges, these basins have been filtering life through an unforgiving sieve for millennia, and what survives here has earned its place.

In the broad interior basins, dwarf scrub of sagebrush and Astragalus clings low to the ground, minimizing exposure to desiccating winds. The more arid zones support halophytes -- salt-tolerant plants...

The Asiatic cheetah, a subspecies distinct from its African cousin, is now critically endangered -- perhaps fewer than thirty indi...

The salt flats of the Dasht-e Kavir gleam white and featureless, broken occasionally by polygonal cracking patterns that look geometric from altitude. Sand seas shift between rust and gold depend...
