For the preparation of the nationwide hunting statistics, regional data on game shootings and wild animal losses (game casualties) of individual ground game and game bird species are collected annually via the responsible federal province offices, after being transferred by the district administration authorities or federal province hunting associations. However, not all hunted wild animal species are included in the survey, but only a certain selection of species, some of which are typical for individual federal provinces. Hunting is regulated by federal province laws, which delimit the respective regional hunting year in different times (calendar year: Burgenland, Carinthia, Lower Austria, Salzburg, Vienna; 1 April–31 March: Upper Austria, Styria, Tyrol, Vorarlberg).
