(Na). Mineral lick sites play a critical role in the ecology and diversity of organisms that visit these sites, however, little is still understood about the dietary benefits. "The adjectives ‘mineral’ and ‘salt’ bear witness to the common proposition, in the ecological literature, that animals eat soil to satisfy a craving for nutrient minerals, resulting from inadequate forage...However, for wild animals which frequent licks, sodium (Na) is the only mineral identified so far, with strong evidence that an extra supply is indeed needed and sought in some cases." Nonetheless, many studies have identified other uses and nutritional benefits from other micronutrients that exist at these sites, including Selenium

People use salt licks to attract or maintain wildlife, whether it be for viewing, photography, farming, or hunting purposes. "It should be noted that sustaining artificial licks during hunting season is considered baiting and is illegal in many states."
