This is an excellent book. It is more about foraging in your local area then going home to prepare it, than it is a book about preparing foods in the wild (though it does have some of that). Each entry has at least one way to prepare it. Some entries have several recipes.
There are descriptions of each plant, and line drawings of them. That is helpful, but if you are not already familiar with the plants, you need to have an experienced person go with you to teach you how to identify each unfamiliar plant.
Second best, would be a good book with good quality color photos (be very careful that the book is not written by AI; those books are incredibly untrustworthy. We're talking about safety and your life here).
the first time i saw arugula on the menu in sf, for 8 dollars! no less, i was appalled--talk about a disconnect from your basic weed crop -- i have other, flashier more comprehensive guides, but i have soft spot for this guy's connection to the animal/survival aspects of the woods my copy is from '74
This is a good book, and could be useful. The draw backs are that you really need to have it with you or spend a lot of time studying it (LOL). Still should you be in a spot, out and away, this will give you an idea what you can eat from the wild without poisoning yourself, or others with you.
It would help to have photos instead of line drawings and again it will be necessary to know what's in it when you need it...but it's better to have it than not.
Superior to many books in the field. My only complaint is that it's quite old and has drawings instead of pictures which could be more useful. I also feel the author doesn't stress enough the dangers of confusing certain plants with toxic ones.
