2.5 Habitat for the species in the biogeographic region or marine region
2.5.1 Habitats for the species / Ideal otter biotopes have the combination of unpolluted water that abounds in aquatic prey and rich vegetation on the banks, which provides shelter. However, as long as there is a variety of hiding places scattered along the hunting grounds, home ranges can include all types of land use (even towns).

2.7.2 Favourable reference population / Much more than field 2.4.120
2.7.3 Suitable habitat for the species / 3460
2.7.4 Other relevant information / During the first half of the past century, otter was present all over the region. However, as a result of active persecution, numbers declined spectacularly. Later on, the destruction of habitats (including water pollution) caused a deathblow so that from the 1980’s the species was considered as extinct on a population level. Only some individual erratic animals have been reported since, but nowhere permanent settlement with reproduction. Beside, otters have very big home ranges, e.g. up to 20 km river length. Since the 1980’s, permanent settlement with reproduction was nowhere noticed. Only some erratic animals have been reported in some periods. Dramatic decline during first half of past century, followed by a progressive deathblow ; extinct on a population level since the 1980’s Ideal otter biotopes have the combination of unpolluted water that abounds in aquatic prey and rich vegetation on the banks, which provides shelter. However, as long as there is a variety of hiding places scattered along the hunting grounds, home ranges can include all types of land use (even towns). Food: fish communities are slowly re-establishing (NARA 2003, 2005) Minimum viable population number is about 20-30. If considering three locations, populations should totalize about 100 specimen to be favourable.
