What the ban does not excuse you from knowing
No hunting does not mean no wildlife: the canton documents living alongside wild animals rather than taking them.
The ban does not make the game disappear, and Geneva devotes most of its communication to living alongside wildlife rather than taking it. Wild boar, red deer and small carnivores live here, with the friction that implies in a peri-urban setting. For a hunter the practical consequence is simple and absolute: carrying a hunting firearm in action on Geneva territory has no legal basis. There is no zone, season or species on which a private exception opens. Management measures — on the red deer of the Versoix woods, for instance — are carried out and documented by the canton itself, which publishes its legal bases and directives for nature management.
