Les populations de cerfs, de chevreuils et de sangliers explosent en Europe, générant des difficultés de gestion en ville et en milieu rural. Qui commet les dégâts : l’homme qui détériore l’environnement naturel de la faune dans son intérêt économique ou bien la faune qui prélève les productions humaines pour survivre ? Selon l'auteur, l’équilibre entre les Ongulés et les milieux forestier ou agricole repose sur la connaissance du comportement des animaux et sur la régulation par la chasse, sans oublier la mortalité naturelle due à la réapparition des grands prédateurs. La solution résiderait avant tout dans la concertation entre usagers de la nature.
Public : chasseurs, forestiers, agriculteurs et passionnés qui recherchent l’équilibre entre le grand gibier et son milieu.
This book traces the history of birds right back to their reptilian origins. It underlines their homogeneity - flight, beak, skeleton and feathers are a bird's reference points - without losing sight of their diversity. Morphological and biological diversity (reproduction especially), but also adaptative. How do they withstand the cold and the predators, how do flightless birds run, how do you fly when you are a vulture? This book explores the intimacy of birds whose habits awaken the curiosity - the Grey Cuckoo, certain species of pigeon or the Hamerkop. It also discusses the relationship between humans and birds.
