I think that part of the problem with looking at it like that is youre narrowing down the skill base that is bushcraft. For me its a huge thing that covers anyone that gets out doors, or even does stuff inside. I know people that are fantastic at fungi, trees and walking mountains, I know others that are fantastic at building shelters and skinning animals, but theyve never purified water or know where to start with foraging and cooking. These are still people that get out there and are comfortable in the outdoors.
I know a photographer thats started learning the names of the trees and how to forage, he doesnt know how to build a shelter or carve anything but hes still out there doing something to increase his knowledge. He says hes bushcrafting and I agree with him (Hes far better at plant ID than I am
). The term reflects an attitude and a journey to knowing more about the environment around you.
Its being comfortable in the Wilderness (generally speaking) I think that the first step is to be comfortable spending time in the outdoors. I know that having a deep and broad skill base helps with this but that comes further down the line. Having a desire to get out, try new things, learn and experiment, push oneself and get more from the world around them. I think that should be level 1 even if they end up in a B&B or go home of an evening.
Theres too many areas to the whole thing to narrow it down into levels, theres people that know far more than Ray about a lot of things to do with the outdoors, hes on a journey of learning just like everyone else. Im loath to do a level system.
Saying that I do understand what youre getting at, its nice to be able to measure ourselves as theres so much to take in and learn and do. Just building a successful fire is an accomplishment and a skill, building one with damp materials is more so and as for building a good fire in the pouring rain, heck, thats hard work!
I think that just getting out there is a basic accomplishment, then developing a basic skill set another, then developing further skills in areas of interest. A lot of people that get out have particular interests in certain areas, the basic skill set helps them expand these interests, it doesnt necessarily develop the basics much, although they are being used so inadvertently they will be strengthened and expended.
And then youve got the environment itself, woodlands, desert, mountains, snow, water, Summer, winter, Jungle, prairie, ocean, river etc Being able to light a fire in one place doesnt mean you can light one somewhere else, so its all based on you as an individual.
In my mind anyone that gets out and learns stuff or even sits at home making cordage and identifying plants theyve picked, or some such, does bushcraft, woodcraft, campcraft (whatever term is comfortable), they are at a basic level and it grows from there.
