Tunnelling for thermal comfort

Probably the best incentive (but not the only reason) to consider our fellow mobile inhabitants of planet earth in our designs is their incredible cuteness. Unfortuneately, even the cutest of creatures, the wombat can be considered a ‘pest’ because they damage crops and fences and cattle may break their legs when they step in their burrows and because their burrows provide shelter for that other notorious crop damaging pest the rabbit. However the wombat apart from its cuteness has some interesting tunneling experience from which the astute engineer could learn. Wombat burrows are well designed and well ventilated.  “Since temperatures underground are more moderate (less variable), the burrows help keep the wombat cooler in the warm months, and warmer in the cooler months. The burrow’s design provides a stable micro-environment for the wombat by controlling the temperature, oxygen, and carbon dioxide levels.”
