There are several definitions of bushcraft floating around the web, none of which I agree with. The most common is the one used on the Wikipedia page that states that bushcraft is the long-term adaptation of survival skills. I disagree. Bushcraft goes way beyond survival skills.
Bushcraft is the active component of our interaction with nature. Both art and science, bushcraft is doing, making, crafting, traveling, building and living in the natural world using simple, low-tech tools. Static knowledge, such as how to care for tools, etc., is a small percentage of the discipline. The vast majority is active, dynamic and hands-on.
