[12], Gestation lasts 20 to 23 days. A female vole will reach sexual maturity in around thirteen days – that’s less than two weeks. [22] Meadow vole habitat devoid of tree cover and grasses dominated the herb layer. Vole runways result from the voles eating the grass blades, as well as from the constant traffic of numerous little feet beating the same path. [3] A threshold density of cover is thought to be needed for meadow vole populations to increase. Predators, particularly raptors, should be protected to keep meadow vole populations in check. … Meadow voles may damage woody vegetation by girdling when population density is high. Square habitat patches were not significantly different from rectangular patches in meadow vole density. Two species are responsible for the majority of damage. Normal population cycles do not occur when dispersal is prevented; under normal conditions, dispersers have been shown to be behaviorally, genetically, and demographically different from residents. Askham, Leonard R. (1992). Voles live on the surface of the ground, creating little round tunnels in grassy vegetation. [14], Patterns of mortality apparently vary among meadow vole populations. ), prickly pear (Opuntia spp. ); racers and voles often use the same burrows. These pests prefer to eat plants, so those that do wander indoors won't find many reasons to stay. There are 124 species, 23 of which are native to the United States. The tunnels are dug at a rate of 18 feet per hour and can add 150 feet of new tunnels in lawn each day. The meadow vole, then, is a small but significant component of our Nature Trail ecosystem. That’s why it’s important to learn how to get rid of voles. [18] Meadow voles in optimal habitats in Virginia (old fields with dense vegetation) reached densities of 983/ha (398/ac); populations declined to 67/ha (27/ac) at the lowest point in the cycle. The more meadow voles you have, the more holes you're going to have. [34], Meadow voles tend to remain in home ranges and defend at least a portion of their home ranges from conspecifics. Moisture may be a major factor in habitat use; possibly the presence of free water is a deciding factor. Edge effects in patches of this size were not found, suggesting meadow voles are edge-tolerant. In Michigan, strip clearcuts in a conifer swamp resulted in an increase in the relative abundance of meadow voles. Moreth, Louis H.; Schramm, Peter. The meadow vole is the most widely distributed vole in North America. Other winter diet components include seeds, roots, and bulbs. [18] Voles (Microtus spp.) ), yellow-bellied racer (Coluber constrictor flaviventris), gopher snake (Pituophis melanoleucas), rattlesnake (Crotalus viridis), and rubber boa (Charina bottae). In the spring and summer, they primarily consume living plants (grasses, sedges, plantain, and a wide variety of “weeds”). Unlike a mouse, this creature has a short, stubby tail less than half the length of its body, small rounded ears, and an oval-shaped head rather than a pointed snout. Rabbits dont have anything over this pesky rodent. [38] Predator numbers are positively associated with meadow vole abundance. In spite of the fact that they live in locations within close proximity to one another, they … Vole Damage. However, if they escape all predators, a vole can potentially live up to two years. In a compilation of 11 studies[5] on small mammals, meadow voles were reported in only three of 29 sites in subalpine forests of the central Rocky Mountains. Radiating out from these nests are networks of shallow burrows through which the voles run in search of food. ), have been reported in meadow vole diets. Voles Voles, also known as field mice, are small brown rodents very common in yards and fields. Voles are herbivores. "Protection with vexar cylinders from damage by meadow voles of tree and shrub seedlings in northeastern Alberta". Prairie voles are more accustomed to eating grass as this is what they are accustomed to, while meadow voles are keener on agricultural plant species. The meadow vole is a small, dark gray rodent often mistaken for a mouse when seen scurrying through a patch of dense vegetation. One subspecies, the Florida salt marsh vole (M. p. dukecampbelli), is found in Florida, and is classified as endangered. Their range extensions were likely to be related to irrigation practices. [38] Most mammalian predators take microtine prey. Predation and Disease [27] In South Dakota, meadow voles prefer grasslands to Rocky Mountain juniper (Juniperus scopulorum) woodlands. [3] Home ranges vary in size from 0.08 to 2.3 hectares (0.32-0.9 ac). Meadow voles, the most common voles in Pennsylvania, are herbivores and eat a variety of grasses, seeds, and roots. Previously it was also found in Chihuahua, Mexico, but has not been recorded since 1998. Voles are rodents of the Northern Hemisphere, inhabiting North America, Europe and Asia. Whichever vole species gets near your property, however, you’d do best to keep them away. [3][12] In summer and fall, grasses are cut into match-length sections to reach the succulent portions of the leaves and seedheads. They are constructed of woven grass; they are usually subterranean or are constructed under boards, rocks, logs, brush piles, hay bales, fenceposts, or in grassy tussocks. [40] In forest plantations in British Columbia, an apparently abundant (not measured) meadow vole population was associated with a high rate of "not sufficient regeneration"; damage to tree seedlings was attributed to meadow voles and lemmings (Synaptomys spp.). [3] Almost all species of raptors take microtine (Microtus spp.) The Microtus voles live in small colonies of a few to 300 individuals in grass meadows where they build distinctive runways which crisscross the area. Voles’ diets are exactly what makes them the annoying pests that they are. [3] The maximum lifespan in the wild is 16 months,[11] and few voles live more than two years. Their fur is generally thick and light brown to gray. Sometimes referred to as meadow mice or field mice, these little critters can do a lot of damage in your lawn and garden. The average meadow vole lifespan is less than one month because of high nestling and juvenile mortality. [46] It prefers open, nonforest habitats and colonizes such open areas created by fire or other clearing disturbances. [30] In west-central Illinois, they were the most common small mammals on Indian grass (Sorghastrum nutans)-dominated and switchgrass (Panicum virginicus)-dominated study plots. If you're trying to maintain a beautiful landscape, this type of damage can be costly to deal with. [12] Home range size depends on season, habitat, and population density: ranges are larger in summer than winter, those in marshes are larger than in meadows, and are smaller at higher population densities. Two common species of voles in North America are the prairie vole and the meadow vole. [46] In these new open areas, the vole quickly becomes a food source for predators. They are socially aggressive and agonistic; females dominate males and males fight amongst themselves. [46] The meadow vole is an important food source for many predators, and disperses mycorrhizal fungi. Voles, for the most part, stay outdoors where they like to burrow tunnels to travel through, give birth to their young, and store their food. Voles are rodents and are about the same size as moles (4 to 6 inches in body length) with relatively large black eyes, small ears, a blunt face, and prominent orange front teeth for gnawing. ), northern shrike (Larius borealis), black-billed magpie (Pica pica), common raven (Corvus corax), American crow (C. brachyrhynchos), great blue heron (Ardea herodias), and American bittern (Botaurus lentiginosus).
