Prairie voles are active year-round. They can damage the trunks and roots of trees by gnawing. Prairie voles are highly social. The young are born hairless and develop rapidly, acquiring a brown coat of fur by day two, crawling three days later, and eating solid food by day 12. Populations which are monogamous show relatively minor size differences between genders compared with those using polygamous systems. Copyright 1999. Prairie voles live in colonies and have been known to exhibit human-like social behavior in groups. The young are born in a ball-shaped nest of dry grass that is usually underground or in a small depression on top of the ground. Vegetation is eaten on the spot or carried below ground. They are weaned at 2-3 weeks, and are fully grown by two months. Populations of the prairie vole fluctuate from 200 per acre to practically none; their changes in density are not as regular or extreme as those exhibited by the meadow vole. It has a stocky and stubby body, short tail and legs, and its eyes and ears are small. Its total length is 5 to 7 inches (nose to tip of tail) and … You must take immediate action to prevent the loss of valuable plantings. The pelage is generally grayish-brown with black and brownish-yellow tipped longer hairs, which gives them a grizzled appearance (Mumford and Whitaker 1982; Jones and Birney 1988; Stalling 1999), although several color variations have been found (Stalling 1990, 1999). The prairie vole is a medium-sized vole with a stocky, compact body (Jones and Birney 1988). Sexes are alike. Rabbits also chew on young trees, but their gnawing begins several inches above the soil line. The damage they can do to ornamental plants, trees, and garden plants can be quite severe and take several years to replace. This is called girdling. When it is associated with the meadow vole it is generally in the drier habitats. The sides of the body are lighter and the belly is yellow to grayish white. The main runways are seldom exposed except where they cross large animal trails or sparse grass cover. Its total length is 5 to 7 inches (nose to tip of tail) and has an average weight of just under 2 ounces. Return to the Mammals of Kansas index page. It spends considerable time in well-defined runways which it makes and maintains in grass. Throughout the year it is active mainly at night, but sometimes by day as well,. Females are capable of breeding 30 days after birth, and males at 35 days, when both are approximately two-thirds the adults size. (Hazard 1982). These runways are approximately 50 mm wide; some are relatively deep and bare while others are faintly imprinted as trampled grass and debris on the ground. Fun Facts: •Like other voles, Prairie Voles are subject to cyclical population fluctuations. Reproduction: They have the same partner to help raise and care for their young. Color photo by Barbara L. Clauson. Food: Food consists of soft basal segments of grasses, some tubers and roots, seeds and , rarely, animal food. Step 2: Learn about the VOLE CONTROL Bait Station System, Step 3: Locate voles with the Apple Sign Test, Above ground foraging Prairie Vole populations can be controlled with the, Pictures from - National Museum of Natural History ©2004 Smithsonian Institution, Look for signs of stress in your ornamental plantings. Longevity of this rodent is generally less than a year, but potentially it can live three or four years. Ecology: Prairie voles build well-defined runways above and below the ground. All rights reserved. It is important to act before vole numbers get too high, especially before winter snow provides cover. Habits: The prairie vole is the most common microtine in Kansas. Vole La Lumiere are a UK based mens fashion brand. Above ground foraging Prairie Vole populations can be controlled with the Vole Control Bait Station System in the Tent Set-up Method. Description: The prairie vole is a medium-sized animal similar in appearance to a mouse. The tiny newborns are pink and hairless, but have fur within 5 days. Reproduction: The prairie vole breeds throughout the year (three or four litters) except during the hottest, driest summers, or severe winter.After a gestation period of 21 days, one to seven (usually three or four) hairless young are born with both eyes and ears closed. The gnaw marks are about 1/16 to 1/8 inch wide and 3/8 inch long found in irregular patches and at various angles. In colder weather, they tend to be more active during the day; at other times, they are mainly nocturnal. It is the most common vole of the Great Plains grasslands. Prairie voles gnaw and girdle trees and saplings at ground level as well as below ground. Size: Adults may attain the following dimensions: total length 137-180 mm; tail 24-45 mm; hind foot 17-23 mm; ear 10-15 mm; weight 49-71 grams. d. winters in the prarie voles' habitat are often harsh, with temperatures that drop well below freezing. Their eyes and ears open in about eight days, and in two or three weeks they are weaned. Vole The bank vole (Myodes glareolus) lives in woodland areas in Europe and Asia. They store food in underground chambers for later use during the winter. Physical characteristics: The Prairie voles fur is long and coarse with a mixture of grayish brown and black giving it a "peppery" appearance. If this gnawing completely surrounds the root or trunk of the tree or shrub, it will kill the plant. Reproduction: The prairie vole breeds throughout the year (three or four litters) except during the hottest, driest summers, or severe winter. The girdling may be higher in the winter months if snow cover exists. They occur at various angles and in irregular patches. If you detect tunneling, then set up a test in the area with the. Search and feel for underground tunnels around the base of the stressed shrubs that may reveal vole activity. Area of Distribution: Prairie voles live in the central grasslands of North America from central Canada to Oklahoma, east of the Rocky Mountains to West Virginia. Signs of Prairie Vole Activity: The evidence of their presence resembles both meadow and pine vole activity. When snow cover is present, voles are protected from predators and their activity can go undetected until it is too late. After a gestation period of 21 days, one to seven (usually three or four) hairless young are born with both eyes and ears closed. This vole stores greater quantities than does the meadow vole, and stored food reflects the kinds of common food available. Description: The prairie vole is a stocky, compact-bodied rodent that can be distinguished from other members of its family by: 1) small eyes and ears inconspicuous on the relatively large head, 2) grayish to blackish-brown upperparts (more grayish in central and northwestern Kansas than in eastern Kansas) with a mixture of blackish to fulvous tips on the guard hairs giving the hairs a grizzled effect, 3) paler sides, 4) ochraceous to grayish white underparts, 5) short tail dark above and light below, and usually about twice the length of the hind foot, 6) females have six nipples, 7) four islands of dentine in the upper second molar, and 8) upper incisor teeth not grooved. Status in Tennessee: There are no conservation concerns for the Prairie Vole as they may be plentiful. Voles move along runways by creeping or by darting. Prairie voles construct surface runways that are easy to recognize by the closely clipped vegetation within them. Rabbits have much larger teeth than voles and their regular gnaw marks on the trees will show this. Effective action involves using the Vole Control Bait Station System, habitat modification, and regular monitoring in the fall and spring with the Apple Sign Test to detect any resurgence from surrounding areas. The underground nest (200 x 130 x 110 mm) made of grass stems and finer lining is placed 250 mm or more deep. Weaning occurs at 2-3 weeks and they are adult size after 3 months. In winter they eat bark of woody plants. A vole colony consists of a pair of animals but more than likely will include several generations. The small burrow entrance holes lead to underground runways and nesting areas. Basic facts about Prairie Vole: lifespan, distribution and habitat map, lifestyle and social behavior, mating habits, diet and nutrition, population size and status.
