The use of camera traps to monitoring of the <i>Mustelidae</i> predators
Camera traps were installed on the banks of forest rivers, on their tributaries and streams. Odorous bait from the excrement of domestic ferrets (Mustela putorius furo) was spread out in front of the cameras. The placement of the predators is also was monitored through the collection of excrement and the subsequent analysis of mitochondrial DNA. A total of 68 rivers were examined, most of which are small, with a channel width of less than 3 meters. The cameras recorded 13 species of mammals, 31 species of birds, voles and wood mice, as well as a large snake. Most commonly encountered: American mink (Neovison vison), otter (Lutra lutra), pine marten (Martes martes) and squirrel (Sciurus vulgaris). There was a division of space between different of Mustelidae species on some rivers. It was succeeded to fix differences in activity in time between the American mink and an otter by means of cameras.
