Southern Water Vole

Arvicola sapidus

Vulnerable

At high risk of extinction in the wild over the medium term.

Spotted something wrong?

The southern water vole is a semi-aquatic rodent endemic to the Iberian Peninsula and France. It digs tunnels in the banks and feeds almost entirely on plants: rushes, grasses and roots. It swims and dives well and, when surprised, throws itself into the water with a characteristic plop. Its populations are in sharp decline across its whole range because of the canalisation of rivers and irrigation channels, the loss of riverside vegetation and predation by the introduced American mink.

Fun facts

  • GeneralIt digs burrows into the banks and swims well; it is in decline as riverside habitat is lost.
  • It is endemic to the Iberian Peninsula and France and is in sharp decline throughout its range: it is one of the Spanish mammals whose position has worsened fastest in recent decades, and yet it goes almost unnoticed.
  • Its disappearance has been linked directly to the spread of American mink that escaped from fur farms, which prey on it efficiently along stretches where it used to be abundant.
