What is the absolute necessity for Xerus locations regarding habitat structure?

Suitable substrate for burrowing

A fundamental and unifying factor across the habitats of all *Xerus* ground squirrels, regardless of their specific genus location (East, West, or South), is the absolute necessity of a suitable substrate for constructing elaborate burrow systems. These intricate tunnel networks are vital, serving multiple critical functions: providing protection against various predators, offering essential refuge from adverse weather conditions such as extreme heat or unexpected cold, and acting as larders for food storage. Even if climatic conditions are favorable or forage is abundant, the physical properties of the ground—its ability to be excavated and maintain structural integrity—will ultimately determine whether a colony can successfully establish and sustain itself long-term.
