In the past few years, foraging—collecting edibles in the wild—has become more popular as people have rediscovered the joy of connecting with nature and enjoying its bounty. Done properly, foraging can be a fun activity, and benefit nature too. I’m not talking about commercial foraging (which can have drawbacks), but a more fun and personal approach to the concept of eating wild food.
Personally I actually like to use the term wildcrafting, instead of foraging. The difference is subtle but important: Wildcrafting is not about taking from nature, but working with it and even helping the environment.
Wikipedia has an excellent definition for wildcrafting :
Wildcrafting is the practice of harvesting plants from their natural, or “wild” habitat, for food or medicinal purposes. It applies to uncultivated plants wherever they may be found, and is not necessarily limited to wilderness areas. Ethical considerations are often involved, such as protecting endangered species.
