Poaching has traditionally been defined as the illegal hunting, killing, or capturing of wild animals, usually associated with land use rights.Until the 20th century, mostly impoverished peasants poached for subsistence purposes, thus supplementing meager diets.By contrast, stealing domestic animals (as in cattle raiding, for example) classifies as theft, not as poaching.Since the 1980s, the term "poaching" has also referred to the illegal harvesting of wild plant species.In 1998 environmental scientists from the University of Massachusetts Amherst proposed the concept of poaching as an environmental crime, defining any activity as illegal that contravenes the laws and regulations established to protect renewable natural resources including the illegal harvest of wildlife with the intention of possessing, transporting, consuming or selling it and using its body parts.
