Look for fresh trails in the grass, burrows, droppings, and evidence of feeding in the garden and surrounding area. You’ll normally find them in areas with dense vegetation. Due to digging, Meadow voles contribute to aeration of the soil. Once vole numbers begin to increase rapidly, the damage they do to ornamental and garden plants and to trees can be quite severe. Native to both Newfoundland and Labrador. Vole damage to tree trunks normally occurs from a few inches aboveground to a few inches below ground. Meadow voles (particularly females) establish relatively fixed home ranges over areas of 0.1 to 1.0 acres. Most scientists believe that the evolutionary reason for the mating differences between voles is that species like the woodland and prairie vole needs to be monogamous in order to protect the litter from predators. Litter size ranges from 3 to 6 young. O’Brien, J. M. 1994. Predators such as hawks and owls should be encouraged. However, in most cases predators can’t keep vole populations below damaging levels. rodents as prey. Microtus pennsylvanicus. I had come across vole signs before: twisting trails in melted snow and white skulls with yellow incisors revealed in owl pellets. Vole species form the subfamily Arvicolinae with the lemmings and the muskrats. Unfortunately, we cannot provide individual solutions to specific pest problems. Six species of voles from the genus Microtus occur in California. Cartilage, and how decomposers and detritivores, which are decomposers, producers, consumers and... 20 years of experimental warming decreased the water content of dung and hence the survival of beetles... Group of detritivores who consume dead organisms for food and replenishes the contains. Voles usually damage plants at or just beneath the soil surface, making adequate coverage difficult or impossible. Most problems around homes and gardens occur during outbreaks of vole populations. It also digs burrows, where it stores food for Meadow voles tend to be active at night during the summer and in the daytime during the winter. The vole is a good swimmer and makes burrows just under the surface of the ground. Leaving wide field margins beside hedgerows provides cover and food which will encourage and maintain populations. Active during the winter, they can strip the bark of trees in yards, particularly fruit trees. For noncommercial purposes only, any Web site may link directly to this page. Coop. They have a compact, heavy body, short legs, a short-furred tail, small eyes, and partially hidden ears. Common Name: Meadow Vole, (Information for this species page was gathered in part by Ms. Melissa Alo for an assignment in Biology 220W, Spring 2006). Meadow voles were not studied beyond 14 days because the colony stopped reproducing before tests at the later ages had been conducted. Three species of voles occur in the state: woodland vole (Microtus pinetorum), meadow vole (Microtus pennsylvanicus), and prairie vole (Microtus ochrogaster) (Figure 1). Monitoring was done on 13 litters of pine voles and 10 litters of meadow voles, with a total of 37 tests on individual pine vole pups and 21 on individual meadow vole pups. Division of Agriculture and Natural Resources Some accident, some run-in with a predator left it with half a tail. Where snow cover is present, damage to trees can extend a foot or more up the trunk. You also can try a dog, but not all dogs find searching for voles an exciting pastime. Description. Solicitors in Ilford, Essex. Voles are active day and night, year-round. Habitat. The California vole, M. californicus, is the most widespread vole in the state, found in the Owens and Central valleys and nearly the entire length of the coastal range. They are the staple foods of weasels, marten, foxes, coyotes, all owls, most hawks, inland breeding gulls, jaegers, and occasionally great blue herons, domestic cats, … Reproduction Cats are a natural predator for voles, and the rodents stay clear of any property that has cats nearby. Commercial repellents are available for protecting plants from voles, but their effectiveness is questionable and their use often isn’t practical. Females mate as early as one month old, and some voles give birth to more than 17 litters in one year. The reproduction cycle of voles is so fast it sounds unbelievable. Hawks, owls, herons, crows, and blue jays along with skunks, weasels, cats, raccoons, and shrews all hunt and eat meadow voles. With an average litter size of four to six pups, every four weeks between March and December, voles fuel the New England food web. Voles are mostly herbivorous, feeding on a variety of grasses, herbaceous plants, bulbs, and tubers. Fence Around Your Vegetable Garden To accomplish this, the first 20 tags (Group 1) recovered were compared with the second (Group 2). 21385. Meadow voles, belonging to the genus Microtus, are colored brown or gray and are mainly found in habitats with grass. Feeding upon grass, they recycle the nutrients, found in the grass, through defecation. Females can have five to ten litters per year. When voles aren’t numerous or when the population is concentrated in a small area, trapping can be effective. Wildlife Pest Control around Gardens and Homes. Their ears are furred and project slightly above the fur on the head. Although the field vole is numerous, it is still important to consider conservation methods and maintain biodiversity within habitats because field voles are so important to owls and other predators. Vole scat : A vole tunnel from a vole's eye view. PDF reader. Anticoagulant baits are available at some county agriculture commissioners’ offices as well as at retail stores. A plastic cylinder protects the trunk of this young tree from vole damage. Meadow voles have a very wide range of predators. You can protect young trees, vines, and ornamentals from girdling by using cylinders made from hardware cloth, sheet metal, or heavy plastic that surround the trunk. You also can try a dog, but not all dogs find searching for voles an exciting pastime. Predators. See our Home page, or in the U.S., contact your local Cooperative Extension office for assistance. Voles. Because populations won’t increase indefinitely, one alternative is to do nothing, and let nature limit the voles. Diet Meadow voles eat 60 percent of their body weight each day. Be alert for the presence of voles. Voles have a slightly heavier build, however, especially in the autumn and winter months while mice are leaner and more “athletic”. Voles are poor climbers and usually don’t enter homes or other buildings. The Regents of the University of California. In addition, a wide variety of snakes (including black snakes and hognose snakes), snapping turtles, bullfrogs, and even largemouth bass eat this incredibly abundant prey species. An important food source for predators from fishers and bobcats to coyotes and even blue jays, meadow voles have an almost year-round ability to reproduce. Also make sure they are wide enough to allow for tree growth and, in areas with snow, are tall enough to extend above snow level. Meadow voles only live for 1 to 1½ years in the wild and hardly any longer in captivity. These voles also accelerate the dispersal of vital mycorrhizal fungi, and, thus, influence the survival and growth rates of many important species of trees. Voles can breed any time of year, but the peak breeding period is spring. Continue to trap in one location until you stop catching voles then move the trap to a new location 15 to 20 feet away. Koivula and Korpimäki concluded that odor from vole scent posed a greater risk to voles than did ultraviolet visibility by avian predators. If you remove this protection, their numbers will decline. They are protected this way from predators from above, like hawks. Produced by University of California Statewide IPM Program. Prairie voles are monogamous—both males and females have a single mate—and males often display parental care and protect their mates. Males, though, especially as they search for mates, tend to move quite freely from territory to territory. In addition, a wide variety of snakes (including black snakes and hognose snakes), snapping turtles, bullfrogs, and even largemouth bass eat this incredibly abundant prey species. The prairie vole’s tail is slightly less than twice the length of the hind foot. When fully grown they can measure 5 to 8 inches long, including the tail. Voles look so much like mice that the average homeowner can be excused for mistaking the two. Baltimore: Johns Hopkins Univ. Long grass on roadside verges is also important. These field mice are larger than house mice with broad heads and short tails. 1994. They range in length from 128–195 mm including the tail, and average 44 grams in weight. Meadow voles play an important role in the local ecosystem. A. Chapman and G. A. Feldhamer, eds. 2019 Aerial predators apparently cue in on vole activity by the visual presence of this scent. Occurs sparingly in mature forests in Newfoundland. Neb. Last winter with its lingering snow cover was ideal for voles to live and feed under the snow with little predator impact. Oakland: Univ. Animalia: pictures (7319) Animalia: specimens (3017) Animalia: sounds (165) Animalia: maps (42) Class Mammalia mammals. The montane vole, M. montanus, inhabits northeastern California and the eastern Sierra slope. Support or brace these devices, so they can’t be pushed over or pressed against the trunk. Voles are mouselike rodents somewhat similar in appearance to pocket gophers. Predators Owls, hawks, snakes, weasels and red foxes feed on voles, who hide from predators in burrows and tunnels. Size: Weighing on average 1.5 oz (48 g) the Meadow Vole is a small rodent that is around 5 to 7 inches long (128 to 195 mm) with a tail that is over 40% of their body size. They are very similar, and methods for controlling them are mostly the same. Bury the bottom of the protective device below the soil surface to prevent voles from digging beneath it. Mammalia: information (1) Females mate as early as one month old, and some voles give birth to more than 17 litters in one year. But this was the first time I’d seen a living vole. The size of the burrow system and foraging area varies with habitat quality, food supply, and population levels, but in most cases it is no more than a few hundred square feet. And finally, these voles are key prey species for a number of predators, … These movements enable dense, clumped populations to disperse evenly, generates an intense natural selection matrix via intraspecific competition for food and other resources, and also assists in the efficient mixing of genetic types (i.e. (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){(i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)})(window,document,'script','//www.google-analytics.com/analytics.js','ga');ga('create', 'UA-46953310-1', 'auto');ga('require', 'displayfeatures');ga('send', 'pageview'); In some areas their numbers are cyclical, reaching peak numbers every 3 to 6 years before dropping back to low levels. But this was the first time I’d seen a living vole. Two species are responsible for the majority of damage. Voles mainly eat stems and blades of lawn grass—so it’s usually vole tunnels that you’ll see near the surface of the yard. Voles cause damage by feeding on a wide range of garden plants including artichoke, beet, Brussels sprouts, cabbage, carrot, cauliflower, celery, lettuce, spinach, sweet potato, tomato, and turnip. Use a sufficient number of traps to control the population. Their greatest benefit to Alaskans is as the prey base for a vast number of predators which Alaskans enjoy viewing, trapping and using. Their presence and activities greatly influence the rate and direction of subsequent successional stages. As with all animals, natural constraints limit vole numbers. They must eat their body weight in food every day in order to survive. Sometimes they make baseball size nests of interwoven strands of dry grass to store food, and someti… When voles are numerous or when damage occurs over large areas, toxic baits can be the quickest and most practical means of control. It has been observed that the meadow vole females to not like to let their young breed although they are mature enough to. Staff-only pages Authors: T. P. Salmon, UC Cooperative Extension, San Diego Co.; and W. P. Gorenzel, UC Cooperative Extension, San Diego Co. The tail is only as long as its hind legs. Commercial pest control operators can use the fumigant aluminum phosphide under very limited conditions. Predators such as coyotes, foxes, badgers, weasels, owls, and hawks feed on meadow voles; however, predation is rarely, if ever, a major factor in controlling a rapidly increasing vole population. Meadow voles will eat flesh and are cannibalistic, especially on new born young. If the damage is below ground, you will need to remove soil from the base of the tree to see it. Meadow voles will eat flesh and are cannibalistic, especially on new born young. And finally, these voles are key prey species for a number of predators… Many other protective measures can be taken. Meadow voles eat many different types of foods. You can reduce the area from which voles can invade gardens or landscaped areas by regularly mowing, spraying with herbicides, grazing, or tilling grassy areas along ditch banks, right-of-ways, or field edges adjacent to gardens. Life History Growth and Reproduction Breeding starts during late winter and continues until August. Voles. The meadow vole (M. pennsylvanicus) is found only in our northern counties. Negative impacts of this behavior may include an increased risk of predation, but the “wandering” voles have been shown to have an overall higher rate of both survival and reproduction. If voles are finding your vegetable garden to be a 24/7 buffet, then you need to stop them in their tracks. Overall body length varies from 3 to 5½ inches for the woodland vole, to about 4½ to 7 inches for meadow and prairie voles. You can cut out both ends of individual milk cartons, tin cans, or plastic soda bottles and fit them over small plants. Generally, spot treating—placing bait in a specific place, such as a runway—is the preferred method of baiting, but in areas of heavy ground cover or if the area you are treating is quite large, broadcasting might be a better option if the label allows it. Because the pest must feed on anticoagulant baits during a period of 5 days, the bait must be available until the vole population is under control. The California Fish and Game Code classifies voles as nongame mammals, meaning if voles are injuring or threatening growing crops or other property, the owner or tenant of the property has permission to control them at any time and in any legal manner. Hawks, owls, herons, crows, and blue jays along with skunks, weasels, cats, raccoons, and shrews all hunt and eat meadow voles. A 4-foot-diameter circle around the base of young trees or vines that is free of vegetation or a buffer strip 4 feet or more along a row of trees can reduce problems, because voles prefer not to feed in the open. Their most common predators include owls, hawks, red foxes Vulpes vulpes , coyotes Canis latrans , bobcats Lynx rufus , and snakes. Find meadow vole information at Encyclopedia of Life; meadow vole. There are a wide variety of vole species, but the majority of species are between three and nine inches long when fully grown. Both the Microtus and red-backed voles form the base of the food chain for many animals in Alaska. Cultural practices can significantly affect meadow vole numbers.
