π The Water Vole (Arvicola amphibius) often incorrectly called a "water rat" is the largest British vole. They're water-loving creatures, preferring slow-moving or still water bodies like rivers, streams, ditches, ponds, and canals, with soft, steep banks for digging burrows.
πΎ They like dense bankside vegetation, such as reeds and grasses, and eat a variety of plant life, including over 200 different grasses and waterside vegetation. In the winter, they eat roots, bark, berries and other foods that they store in underground caches. They can eat about 80% of their body weight each day!
πͺ΅Like mini beavers, voles manage the waterways by foraging and burrowing to increase biodiversity. Their work benefits many species of insect, birds of prey, and bats. Waterways with higher numbers of water voles have richer vegetation and plant life.
π¦¦They can have three to six litters of five young a year and the first litter can be born as early as March or April. Baby water voles are blind and hairless but grow very quickly, leaving the nest after only three weeks and able to breed after 15 weeks. Voles do not live long, most not surviving more than one winter.
βοΈ Although nearly all of our UK wildlife is in decline, water vole numbers have seen a catastrophic reduction in numbers and range over the last few decades, due to habitat loss and predation by American mink. They have also suffered losses this year due to low water levels exposing the entrance to their burrows. Once common, they are now classified as Endangered on the GB Red List and are legally protected.
