What environmental factor prevents wombats from thriving in the arid center of Australia?

Answer

The environment lacks the necessary vegetation and soil structure for survival

The geographical distribution of all four wombat species is intrinsically linked to their basic ecological requirements: sufficient food sources and suitable digging substrate. The arid center of Australia fails to meet these fundamental needs. This region typically lacks the specific types of vegetation required to sustain their diet, and critically, it does not possess the soil composition necessary for them to dig and maintain the sophisticated, deep burrows they rely upon for insulation and protection. Thus, the combination of inadequate food and prohibitive soil structure dictates their absence from those areas.
