Please remember, that foraging is not simply Botany, or plant identification, it is the act of procuring food, and thus so, simply being able to identify plants etc. its self is not foraging, I have plenty of botanist coming on foraging courses, so what are they there to learn? Knowing when to collect a plant or gather the food, which part of the plant and how to prepare it to be eaten and for the body to gain maximum efficiency from the individual food group or plant etc.
Early man first lived on the coast and successfully evolved and grew in population, due to the vast amount of food through out the changing seasons, then took the coastal plants and veg etc. back in land as we cleared a path or burnt the forests down. All in my new book, out soon, that I hope may make it onto your reading list one day?
Keep up the good work, and help spread the word on just how rich and diverse the wild world can be. See you at the Moot I hope big boy!
