Současný areál výskytu mývala severního (Procyon lotor) v České republice dle odlovu (Carnivora: Procyonidae)

Abstract

Current range of Procyon lotor in the Czech Republic based on hunting statistics (Carnivora: Procyonidae). The common raccoon (Procyon lotor), introduced to Europe at the end of the first half of the 20th century, is included in the EU Black List of Invasive Alien Species. Due to its assessed high impact on the European biodiversity, research has been focused on the specific influence of its introduction and evaluating the intensity and direction of its invasion. In the Czech Republic, two separate raccoon populations are known – in northwestern Bohemia and central and southern Moravia. We used the bag records from the Annual reports on hunting grounds, game numbers and game huntings at the level of municipalities with extended competences (ORP) for the retrospective assessment of the raccoon distribution in the Czech Republic. The reports from the hunting years 2011/2012 to 2017/2018 were evaluated. In the first year (2011/2012), 234 individuals were caught in 23 ORP (out of a total of 205 ORP of the country). In the last year of the evaluation (2017/2018), 1,352 individuals were caught in 56 ORP. The highest density of the Bohemian population was recorded in the hunting year 2017/2018 (0.45 individuals per 100 hectares) in the Karlovy Vary ORP. In the Moravian population, the peak was reached in the hunting year 2013/14, when 0.59 individuals per 100 hectares were recorded in the Přelouč ORP.
