The Karoo also hosted a well-preserved ecosystem hundreds of million years ago which is now represented by many fossils. The Karoo formed an almost impenetrable barrier to the interior from Cape Town, and the
Kazakh semi-desert in livestock numbers in Kazakhstan is allowing the native plants a greater opportunity to regenerate.

The climate here is semi-arid and highly continental. Precipitation averages between and annually. Mean temperatures in January range from and , while July means are between and . Annual average temperatures are around . The region's topography consists of vast, flat plains and salt flats broken by dissected plateaus (known locally as ""melkosopochniki""). As a transition
