Vydra riečna v Chránenej krajinnej oblasti Horná Orava

Urban, Peter, 1962- Vydra riečna v Chránenej krajinnej oblasti Horná Orava / Peter Urban, Šimon Kertys. -- The Eurasian otter (Lutra lutra) is a native protected mammal species in Horná Orava Protected Landscape Area (PLA) (northern Slovakia). A field survey and evaluation of the conservation status of the otter population and its habitats was made between May 2021 and November 2022 in 5 Sites of Community Importance (SCIs) in the Horná Orava PLA: Jelešňa (SKUEV0222; 65.469 ha); Jelešňa (SKUEV2222; 93.437 ha); Oravská vodná nádrž (SKUEV0304; 252.114 ha); Oravská vodná nádrž (SKUEV2304; 394.775 ha); Ústie Bielej Oravy (SKUEV0658; 66.068 ha); for the purpose of preparing management programmes for these areas. Currently, the otter permanently and year-round inhabits all larger water bodies in the Horná Orava PLA, or littoral zone of the Orava Reservoir. During the one-off otter mapping in February and May 2022, all 9 controlled quadrates of the Databank of Slovak Fauna (DSF) (ca 10 × 12 km) in the region were positive. Estimated otter population size in the Horná Orava PLA is 25 - 30 individuals. The current main pressures and threats affecting otters are traffic and road accidents, destruction and fragmentation of habitats, water pollution, the use of water resources, illegal hunting and persecution, diverse offer of suitable and available food and its seasonal changes, etc. The conservation status of the otter in the Horná Orava PLA is favourable (FV). It is also favourable in two SCIs (Jelešňa SKUEV0222 and SKUEV2222), but it is unfavourable – inadequate (U1) in 3 SCIs (Oravská vodná nádrž SKUEV0304 and SKUEV2304; Ústie Bielej Oravy SKUEV0658), due to the relatively small area of their suitable habitats for otter.
