Dung beetles play a role in agriculture and tropical forests. By burying and consuming dung, they improve nutrient recycling and soil structure. Dung beetles have been further shown to improve soil conditions and plant growth on rehabilitated coal mines in South Africa. They are also important for the dispersal of seeds present in animals' dung, influencing seed burial and seedling recruitment in tropical forests. They can protect livestock, such as cattle, by removing the dung which, if left, could provide habitat for pests such as flies. Therefore, many countries have introduced the creatures for the benefit of animal husbandry. The American Institute of Biological Sciences reports that dung beetles save the United States cattle industry an estimated US$380 million annually through burying above-ground livestock feces.
