Under certain conditions they may construct burrow systems of more than 30 meters in length. Wombats dig with their front feet, thrusting the soil out with the hind feet, and use their strong incisors to cut such obstructions as roots. The burrow entrance normally is a low arch that fits the body. A grass or bark nest is located near the end of the burrow. A shallow resting place is usually excavated against a tree or log near the mouth of the burrow, as a site for sunbathing.
Paths often lead from burrows to feeding areas.
Wombats eat mainly grasses, roots, bark, and fungi. Wombats do well in captivity and often become interesting and affectionate pets. They have suffered serious reduction in numbers and range. People are their chief enemy. Colonies have been exterminated near settled areas because of damage to crops and because domestic livestock may injure a leg by breaking through into the burrows.
