This guide is for those living in the countryside or practicing hiking, camping or any other outdoor sport. Short, a lot of people. I buy especially for the part on serpents and have so far only had a vague look at the rest of the book but on the basis of what I have read I can deduce that this criticism can be applied to the whole book. This guide is excellent. The explanations, iconography are clear and precise. More questions now confuse a snake and viper. Moreover, the practical guide part well puts things in their place on the dangerousness of a viper bite. A guide that learns not having systematically afraid of a snake met in his garden or on a hiking trail. Insist on the fact that snakes are protected animals and their destruction is punishable by law.
