Hints: African Kalahari savanna ridge scattering excavate Damara mole-rats

It’s the wettest of all African deserts, the great Kalahari.
The sands of the Kalahari cover more of southern Africa than any other desert. But the higher rainfall here gives it a very distinctive appearance. More like a savanna, its sandy ridges carpeted with grasses and a scattering of trees. In the wet season, the Kalahari sands are loosened by the rain, making them easier to excavate.
Damara mole-rats who spend their lives underground are now at their most active, hunting for roots and bulbs. But digging takes one thousand times more energy than traveling on the surface. And even in this greenist African deserts, the bulbs can be widely spread.
