American mink (Neovison vison) control in protected areas in Poland – monitoring of the eradication effectiveness (original) (raw)

2012

Abstract

Biological invasion is a major threat to biodiversity and ecosystem function as the negative impacts of invasive on native species can be devastating. Reducing the density of invasive species is an important goal in protected areas. Understanding the mechanisms that underlie com-pensatory responses in populations of invasive species has the potential to enhance the effectiveness of con-trol programmes. American mink ( Neovison vison ) is a semi-aquatic species, endemic to North America, which was introduced in the wild in Europe in the 1930s. In many introduced areas, the American mink has an excessive predation im-pact on waterfowl and riparian mam-mals, leading to a marked decrease in their density. The aim of this study is to analyse colonization rate of mink after eradication in the 3 National Parks of Poland: Drawa National Park (DNP) situated in western Po-land, Biebrza National Park (BNP) and Narew National Park (NNP), sit-uated in eastern Poland (Fig. 1). The American mink e...
