[5] northern Scotland).[12]. It rakes its hind feet over the gland to push the secretion out and then stamps it into the ground. Water voles can mate on the land or in water and will normally produce an average of around 20 offspring per annum in captivity. The water vole is vegetarian, feeding on a wide range of plants found in and beside fresh water. Weights reported for adults are variable. It has suffered the largest decline of any British mammal in recent years. Habitat destruction used to be the major cause of extinctions, but now it is predation by non-native North American mink Neovison vison that is responsible for much of this … Vole originated from the Norwegian word vollmus; voll, meaning field, and mus, meaning mouse. Breeding females have territories of 30-150m and fiercely defend them, while males having larger home ranges of 60-300m that overlap several females. 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. (2014, March 25). To increase the population density of the water vole within the National Park. Tells of an apparently shy, easily frightened young female by a lakeside, who in the last line of the poem, it is revealed that: National Water-Vole Monitoring Programme (NWVMP), CS1 maint: multiple names: authors list (. They do not usually live in large groups. Mammalian Species, 223, 1-6. The distribution of habitats is found to be extremely variable, due to the geographical barriers of large coniferous forests, mountains, and expansive valleys without readily available waterways. Water voles are a protected species in the UK and the country’s fastest declining mammal, with the population having fallen by 95% since the 1970’s due to loss of habitat and predation by mink. They live under the snow during the winter. Throughout the story, Urk spends a lot of time talking to the water-voles on the farm. [23], A water-vole named "Ratty" is a leading character in the 1908 children's book The Wind in the Willows by Kenneth Grahame: the locality used in the book is believed to be Moor Copse in Berkshire, England, and the character's name "Ratty" has become widely associated with the species and their riverbank habitat, as well as the misconception that they are a species of rat.[24][25].

The European water vole Arvicola amphibius is of high conservation importance in the United Kingdom due to its documented decline in both distribution and abundance. [5], They are active year-round, tunneling through snow during the winter. Because of this system, males travel over a much larger home range than females, and they tend to be more aggressive than females, with aggressiveness coinciding with breeding patterns. Reportedly small Mustela weasels as well as European and introduced American mink may take the largest number of water voles of any predator due in part to aligning habitat preferences. A guide to water vole ecology and field signs Since April 6th, 2008, it has been illegal to trap, harm, kill, injure or disturb water voles Arvicola ... locate surviving populations and inform projects to restore them to their historic range. Yavuz, Güliz, Ercüment Çolak, and Teoman Kankılıç. Water Vole Conservation Handbook (2nd edition). Most water voles only live through one winter, and die at the end of the second breeding season. Brighton University have been working with Sussex Wildlife Trust and others on DNA and habitat analyses to establish new national protocols for water vole conservation. Although, gen… Water voles in some parts of England have been shown to occasionally prey on frogs and tadpoles; it has been speculated that this is to make up for a protein deficiency in the voles' diet. The aim was to test assumptions about the species’ social structure relative to other microtines. The distribution of habitats is found to be extremely variable, due to the geographical barriers of large coniferous forests, mountains, and expansive valleys without readily available waterways. The European water vole (Arvicola terrestris) is the largest of the native Eurasian voles, weighing up to 250 grams (9 ounces) and having a body up to 22 cm (9 inches) long and a tail up to 13 cm (5 inches). The revised UK Biodiversity Action Plan (BAP) targets for water vole, published in 2006 were as follows: n Target 1 Maintain the current range (730 occupied 10km squares) of water vole in UK. In the wild, on average, water voles only live about five months. In addition, water voles tend to limit the extent of their activity to a set range. Our Ecofender™ Water Vole Fence Panels have a life expectancy of up to 15 years. They are found in alpine or semi-alpine meadows near water, usually between 914-3,201 m in elevation. 5-6 young, with a minimum gestation period of 22 days. The water vole is a threatened species. Their food source varies significantly depending on geographic location. Retrieved March 21, 2015, from JSTOR. ... Stoddart DM (1969) Individual range, dispersion and dispersal in a population of water voles (Arvicola terrestris L.). Mus terrestris Linnaeus, 1758. The European water vole or northern water vole, is a semiaquatic rodent. Within the midfield ponds, water voles did not prefer any particular type of littoral vegetation and avoided open water areas within the ponds. In September 2019, the Box Moor Trust reintroducted 177 Water Voles in to the River Bulbourne in Hemel Hempstead as part of a three year plan. They breed prolifically in the summer months, though mortality during the winter is high. Water voles breed for 3 months during the summer, and young are born from June until late September. Water voles are fully protected under section 9 of the Wildlife and Countryside Act 1981 (as amended). Assuming that the minimum home range size for a water vole is 75 m , this equates to a maximum supportable population of 184 animals in the Windrush study area, or approximately nine animals per km of river. Water voles prefer lush riparian vegetation which provides important cover to conceal animals when they are above ground adjacent to the water body. [4], Water voles are usually found within 5 to 10 m from waterways. [2][3] Water voles are on the USDA Forest Service Region 2 sensitive species list because they maintain very small populations and there is high concern that their required habitat may be declining. In Britain, water voles live in burrows excavated within the banks of rivers, ditches, ponds, and streams. One aspect of water vole conservation in the UK is focused on non-linear habitats such as reed bed which support extensive networks or metapopulations. Retrieved March 20, 2015, from, North American Mammals: Microtus richardsoni. Look out for the signs of water voles, such as burrows in the riverbank, often with a nibbled 'lawn' of grass around the entrance. Areas of heavily grazed and trampled riparian habitats are generally avoided. Dominant males increased their range in the breeding season most likely to maximize (“optimize”) the number of females and consequently their reproductive success (prediction 1 … Water voles hold a special place in British hearts, however are sadly the UK’s fastest declining wild mammal and without proactive conservation measures they’ll likely be lost forever. The water vole is a UK BAP priority species, with the Environment Agency (EA) identified as the …
