(n.d.). What good is a water vole and why do they matter? Ludwig, D. (1984, November 14). One of the main reasons for their disappearance is habitat damage. Retrieved March 20, 2015, from, Klaus, M., Moore, R., & Vyse, E. (1999). 2 Addcomplexitytowetlandlandscapes,helpingtoconfound huntingmink,whichcaneradicatewatervolepopulationsalong … Water voles are a native species that used to been seen down our waterways very recently up until the last 30 years or so. They will avoid sites that are heavily grazed, trampled or over-shaded by dense scrub or trees, but will happily live underneath the light shade of brambles and like to eat the leaves and the berries. Our report published in 2017 revealed that between 2006-2015, water vole distribution declined dramatically. [5] Some of their primary habitats include meadows, and other open areas. Journal of Mammalogy, 69(3), 532-541. In years of that are wetter than usual it has been observed that young water voles become reproductively active sooner, and therefore can have more offspring. You just need to make sure that there is plenty of vegetation growing from the banks and emerging from the water to provide food and cover from their many predators and make sure that it is not polluted. https://www.youtube.com/watch?v=Y-fBBFsclNM. The water vole (Microtus richardsoni) is the largest North American vole. During the winter they are seen to dig tunnels through the snow, and usually do not surface above the snow once 6 cm have accumulated (approx. Water voles do not live in Ireland and are absent from most offshore islands except Anglesey, the Isle of Wight and the Sound of Jura Islands. Microtus richardsoni. Their fur is grey-brown, dark brown, or reddish-brown on the upperparts, and is grayish-white on their underside. In lowland areas, water voles occur beside: Klaus, M., Moore, R., & Vyse, E. (2001, July). Soft soils are preferred. Vole originated from the Norwegian word vollmus; voll, meaning field, and mus, meaning mouse. Retrieved March 20, 2015, from, North American Mammals: Microtus richardsoni. Males tend to be larger than females. Water voles were given full legal protection in England & Wales on the 6th April 2008 by provisions under section 9 of Schedule 5 of the Wildlife & Countryside Act 1981 (as amended). It has been found that higher precipitation levels create increased availability of usable habitat for water voles. Nowadays water voles are failing to thrive due to a desperate shortage of ideal habitat. Water voles need river banks to burrow in and they need vegetation for food and to hide from predators. Water voles were formerly widespread and common in England, Wales and Scotland, ranging from Cornwall to the extreme north-east of Scotland. Offences carry a maximum penalty of £5,000. It is easy to provide a home for water voles, so that populations can thrive or expand and move into your waterway, pond or lake. For Old World water voles, see. [4] [5] Evidence shows that although they may still be nesting with their mother, she provides very minimal parental care after weaning. The beauty of managing habitat for water voles is that they help to manage it themselves whilst also increasing biodiversity.

They are still widespread but have undergone one of the most serious declines of any mammal in Britain. If a water vole has a plentiful supply of food, its population will increase rapidly. Look out for the signs of water voles, such as burrows in the riverbank, often with a nibbled 'lawn' of grass around the entrance. Their food source varies significantly depending on geographic location. Paleontological evidence suggests that M. richardsoni diverged from a Mimomys ancestral form in Siberia approximately 1.5 million years before Arvicola evolved in Europe. Incorporate water vole conservation into relevant habitat policies and agri-environment schemes: Ensure that development schemes do not affect the integrity of water vole populations. They construct these tunnels and nests just below the roots of the vegetation (about 4–6 cm below ground) during the breeding season (June through late September). (2014, March 25). The habitat preference varies based on the species, but many avoid densely forested regions. European water voles are found in most of Europe, Russia, West Asia, and Kazakhstan. It is also possible that there were influences from Swedish vall, which translates to mean field. It is best to manage habitat by cutting alternate sides of the bank, or only one side of the bank. Far too many banks across the UK are strimmed to ground-level and over zealously tidied from spring through to autumn, leaving water voles no choice but to move on. Water Vole - Arvicola amphibius Taxon: Rodentia General fact sheet (click to download) Field sign fact sheet (click to download) Habitat: Rivers and wetland, mixed woodland. Your neighbourly help will enable them to survive, as they have now declined by 95% across the UK, partly due to habitat loss, habitat fragmentation and predation by the non-native American mink. There is no evidence that they store food for the winter. They form a polygynous social group,[9] in which females tend to stay within their territory, which does not overlap other females, and males travel between burrows to reproduce with several females. [6], Newborn voles are naked and blind, and weigh about 5 g. They are able to vocalize immediately, and within 3 days start to show fur. In Britain, water voles live in burrows excavated within the banks of rivers, ditches, ponds, and streams. The water vole lives along rivers, streams and ditches, around ponds and lakes, and in marshes, reedbeds and areas of wet moorland.
