Woodrats typically have two pups per litter and females may have up to four litters per year if food is abundant. At one point, the Allegheny rat was hunted for food and sometimes killed due to false identification based on its resemblance to more problematic European rats. This is mostly true for Pennsylvania and Maryland. Allegheny woodrat food station With jobs assigned, the group divides to plant seedlings, and attempt to find signs the woodrat is present in the area. (3.3 – 5 cm) hind foot length; 0.9 – 1.3 lbs. At such times, home ranges may shrink to as little as 0.65 ha (1.6 acres). Latrines are large fecal piles the rats deposit on protected flat rocks. She developed a drug to be distributed through bait that the raccoons would eat, disrupting the growth and shedding of the roundworm parasite for about three weeks, effectively reducing the deposition of roundworm eggs near woodrat nesting sites, therefore reducing the threat of the parasite in woodrats. The Allegheny woodrat is at the northern extent of its range in New York State with only one possibly extant occurrence in Rockland County. https://dx.doi.org/10.2305/IUCN.UK.2008.RLTS.T14581A4446084.en, 10.1644/1545-1542(2001)082<0791:MPOTNF>2.0.CO;2, 10.1674/0003-0031(2002)147[0080:AWNMFH]2.0.CO;2, " NYS Dept. Throughout their range, they are found in mixed pine-oak forest, but they are also found in a range of other forest types, most commonly with a mix of hardwoodtr… The Allegheny woodrat (Neotoma magister) is a rodent native to cliff edges, caves and talus slopes of the Appalachian Mountains (Allegheny woodrat range map).It has been disappearing from the northern portions of its range for more than 30 years. They have large eyes, and naked ears. Plus, the items they bring from forests into caves allow insects and fish there to survive. Their most distinguishing feature is their tails: while the tails of European rats are naked with only slightly visible hairs, the tails of woodrats are completely furred with hairs about one-third of an inch long, and predominantly black above and white beneath. What We Can Do - Conserve habitat by protecting cliff lines, rock shelters, and rock ledges from extensive timber harvest. NPS photo. [15], Allegheny woodrats are mainly distributed along the Appalachian Mountains. [citation needed]. Research / Allegheny woodrat is small mammal that belongs to the group of rodents. Additional Information: Allegheny Woodrats are declining throughout their range. During the summer, males have home ranges of about 6.5 ha (16 acres), and females of about 2.5 ha (6.2 acres). Issues Being Addressed and Rationale for Allegheny Woodrat Monitoring The Allegheny woodrat, Neotoma magister, is a native small mammal of interest on Mammoth Cave National Park (MACA) and across the Eastern USA, due, in part, to recent dramatic population declines. About 50 whiskers are found on each side, consisting of a mixture of stiff black hairs and softer white ones. Linzey, A.V. The diet of Allegheny woodrats consists almost exclusively of vegetable matter that provides both food and water. Dusky-footed woodrats live in loosely-cooperative societies and have amatrilineal (mother-offspring associations; through the … This kind of classification uses a term known as a ‘Superfamily’ to refer to large groups of related animals. [8], In addition to the latrines, Alleghany woodrats of both sexes also scent mark various objects around their home ranges, using a scent gland on their undersides. They are most active during the earlier part of the night, from about a half hour after sunset, and again shortly before dawn. Number of Allegheny woodrats in the wild is rapidly declining due to habitat destruction, parasitic diseases, lack of food and climate changes. [3], Although the Allegheny woodrat is not a federally listed threatened or endangered species, it is in major decline and is state listed:[16][17]. Hard mast is an important food source, especially during winter because this species does not hibernate. The Allegheny woodrat is, throughout its range, associated with extensive rocky areas such as outcrops, cliffs, talus slopes with boulders and crevices, and caves. Allegheny woodrats are packrats and differ from common rats by having larger eyes and ears, furry tails, and longer whiskers. The first reason is a parasite, the raccoon roundworm, Baylisascaris procyonis, which is almost always fatal to woodrats. The Tennessee River is generally accepted as the southern range limit. Allegheny woodrat (Neotoma magister), a native of North America, which has been experiencing large declines due to a number of reasons. The woodrats are an important link in the ecosystem—a food to predators like owls. [8], Nocturnal, Allegheny woodrats spend their nights foraging, collecting food and nesting materials. [3][13], Allegheny woodrats become sexually mature at three to four months of age,[3] and, in the wild, have been known to live up to 58 months. Their diet mostly consists of fungus, and, at the peak of mushroom season, fungus can make up more than 12% of their diet. [20], Pennsylvania is conducting a three-year study[when?] [16] There are no recognised subspecies. [3], Allegheny woodrats prefer rocky outcrops associated with mountain ridges such as cliffs, caves, talus slopes, and even mines. They have also been known to consume bats and insects on occasion. They venture away from their protective shelters at night to feed on and gather nuts, berries, fungi, and vegetation which they sometimes caches in their dens. They have been extirpated from Connecticut, Massachusetts, New York, and parts of Pennsylvania, New Jersey, and Maryland. Plant materials are the primary component of the woodrat's diet. Voice - Sharp squeal; also makes drumming sounds with tail vibrations or thumping of hind feet when disturbed, Young - 30 – 36 days to birth (gestation period); litter of 1 – 3 pups; born in March through September; several litters each year; young born naked, helpless, and with incisor teeth already present; hair appears in five days, ears unfold in nine days, eyes open in 19 days; begin foraging on their own and eating solid foods in 24 days. [19], Indiana's Nongame and Endangered Wildlife Program currently monitors status, distribution, and population. Their food habits differ according to the species and their geographical range. (32 – 47.7 cm) total length; 5.5 – 8.3 in. Allegheny woodrat inhabits cliffs, caves and rocky outcrops. http://users.dickinson.edu/~wright/TeamWoodrat/woodratID/index.html, Carol Hanley, Ed.D.Associate Director201 Dimock BuildingLexington, KY 40546-0076859-257-3785enri@uky.edu, Students / [3], Their diets primarily consist of plant materials including buds, leaves, stems, fruits, seeds, acorns, and other nuts. August 17 update The Allegheny Woodrat continues to do well. Dens are deep in rock fissures, and nests consist of sticks and twigs lined with shredded bark. They sometimes eat bats and insects as well. They have historically been found as far north as Connecticut and possibly Massachusetts (where they are now extirpated), southeastern New York (extirpated), northern New Jersey, and northern Pennsylvania southwestward through western Maryland, Tennessee, Kentucky, West Virginia, northern and western Virginia to northeastern Alabama and northwestern North Carolina with isolated populations north of the Ohio River in southern Ohio (extirpated) and southern Indiana (reintroduced). (394 – 609 g) weight. Woodrats are about the size of a gray squirrel, can live about 3 years in the wild, and have a home range of about 100 yards (91.5m). This species is grayish brown with a white or grayish belly and has a soft coat, large, black, protuberant eyes, and large and sparsely-haired ears. Allegheny Woodrat . Food: Woodrats eat seeds, nuts, berries, and fungus. Woodrats in New Jersey eat a variety of fruits, berries, tree buds, leaves, tree stems, seeds, acorns, and some other nuts. General Information and Life History The Allegheny woodrat is a medium-sized rodent with a long, hairy tail that is found throughout a large portion of the eastern United States (Castleberry et al., 2006). In Pennsylvania, there are only a few known sites where woodrat dens persist. They scurry about in sparsely vegetated areas of boulders and crevices, making use of bare travel ways and labyrinths to travel silently and securely throughout their domain. [9], Individuals are generally aggressive towards each other, especially when competing for nest sites, and, while home ranges may overlap, each actively defends its own den. Woodrats are generally nocturnal. In biology, animals are classified according to what relates them with each other. [5] Throughout their range, they are found in mixed pine-oak forest,[6] but they are also found in a range of other forest types, most commonly with a mix of hardwood trees. The fur is long, soft, and brownish-gray or cinnamon in color, while the undersides and feet are white. This superfamily is known as ‘Muroidea’. They store their food in caches and eat about 5% of their body weight a day. They store food in caches and are known to eat about 5% percent of their body weight in a single day. Woodrats are primarily noctural, venturing out at night to collect buds, seeds, leaves, fruit, nuts, and fungi from nearby forests. This is a medium-sized rodent with a total length of 362-409 mm and a weight of 200-275 grams. They emerge at dusk to forage for food, which includes a variety of leaves, fruit, nuts, seeds, fungi and twigs. The species, first described from a specimen taken in a cave near Carlisle in 1858, has disappeared from the southeastern portion of the state and has declined in much of the rest of the state. Enjoy the videos and music you love, upload original content, and share it all with friends, family, and the world on YouTube. Description: A medium-sized rodent with long, thick fur, prominent ears, large eyes, very long, distinct whiskers, and a furry, bicolored tail that is less than half the total length of the body. Allegheny woodrats (Neotoma magister) faced this firsthand when American chestnuts were extirpated and forests transitioned to become oak-dominated about 100 years ago.These oaks sometimes fail to produce the mast that the species consumes, which may be a contributing to their range-wide decline. Finally, increased human encroachment causes fragmentation and destruction of the woodrats' habitat. The surrounding forest is usually deciduous. In the case of the Woodrat, the animal is of the same superfamily as the Norway Rat (Sewer Rat) and the Black Rat (Palm Rat). [7] Predators include owls, skunks, weasels, foxes, raccoons, bobcats, large snakes, and humans. They feed on green vegetation, acorns, fruits, nuts, fungi, ferns, seeds, berries, leaves, green briar, and hackberry. In fact, the shy, secretive Allegheny woodrat has little in common with the aggressive Norway rat, other than the fact that both are rodents. They live with their mothers in nests composed of grass, bark, and similar materials, often located in relatively inaccessible crevices or ledges. The IUCN Red List of Threatened Species 2008: e.T14581A4446084. Woodrats eat about five percent of their weight in dry matter daily. 2008. [7], New Jersey's Division of Fish and Wildlife's Endangered and Nongame Species Program supported research by Kathleen LoGiudice. Woodrats are also nicknamed "pack rats", due to their habit of collecting and caching non-food items such as bottle caps, coins, feathers, and bones. Departments & Units / Food - Seeds, nuts, berries; sometimes insects, worms, spiders, bird’s eggs, Cover - Piles of sticks are constructed containing assortment of green vegetation, sticks, and often trash, such as glass, paper, and metal scraps; may reach a height of five or more feet; cover protects from most predators except snakes and weasels that can maneuver their way inside; nest is shredded bark in a brush pile or rocky crevice, Breeding - Females breed at less than one year of age; can breed again shortly after giving birth; males can breed at about one year, Habitat - Wooded areas, especially around rock ledges, caves, cliff lines, and rock shelters, Kentucky Distribution - Known from only four counties in the state: Edmonson, Menifee, Pulaski, and Wolfe counties. partially funded by a Game Commission State Wildlife Grant and being led by Indiana University of Pennsylvania in an attempt to shed light on the daily and seasonal movements of woodrats, identify high-quality woodrat habitat, and learn whether providing food caches can boost a population. [21], Maryland's Department of Natural Resources has conducted trappings and surveys to study the woodrat's habitat. [13], Unlike most other rodents, Allegheny woodrats are not prolific breeders. They consume a wide variety of nuts and fruits,fungi, foliage and some forbs (Linsdale and Tevis 1951). It can be found in North America. They help keep the forest floor clean by gnawing on bones, perhaps to sharpen their teeth or to add calcium and other minerals to their diet. They may feed up to 2 ounces of food and require approximately 1-2 ounces of water every day. Their solitary lifestyle, forested habitat, and proclivity for collecting shiny objects (e.g. It occasionally uses abandoned buildings but generally avoids humans. It generally occurs at higher elevations (to about 1000 m) and is rarely found in lowlands or open areas. The typical diet of these creatures consists of nuts, berries, seeds, vegetation, plants, twigs, insects, small mammals, and even birds. Just below the superfamily level of biological class… Ecological Role - Allegheny woodrats have long, sensitive whiskers that help them be active at night (nocturnal). They eat a lot of mushrooms, which can make up 12% of their food. Allegheny woodrats eat mostly plants like berries, fruits, and seeds. Woodrats are frequent visitors to the cave ecosystem and are important Once believed to be a subspecies of the eastern woodrat (Neotoma floridana), extensive DNA analysis has proven it to be a distinct species. In Virginia and West Virginia, woodrats are found on ridges, but also on side slopes in caves and talus (boulders and breakdown) fields. [18] Raccoons easily adapt to environmental change, and have thrived in the traditional woodrat habitat, increasing infection by the parasite, which enters woodrats because they eat the plant and seed material in raccoon feces. Populations in Kentucky seem to be stable. Reasons for this decline are unknown, but this species is in the same genus as the “pack rats” out west, and like them, they make large stick nests in caves, crevices, and even abandoned buildings. Although some species have more specializeddiets than others (e.g., Stephen's woodrat, N. stephensifeeds almost exclusively on juniper), woodrats are, for the most part,generalist herbivores. Currently, they are investigating DNA relationships of Allegheny woodrats under a grant from the Virginia Department of Game and Inland Fisheries. Allegheny woodrat (Neotoma magister) Characteristics. Their work will include radiotelemetry, DNA profiling and mark-recapture trapping. Predators include owls, skunks, weasels, foxes, raccoons, bobcats, large snakes, and humans. The amount of mushrooms they eat changes by location. [22], Researchers at the University of Georgia have studied Allegheny woodrats in Virginia since 1990. of Environmental Conservation", "Fall movements of Allegheny woodrats in harvested and intact stands in West Virginia", "Behavior of captive Allegheny woodrats (, 10.1674/0003-0031(2002)148[0155:RJGARR]2.0.CO;2, "Longevity record for a wild Allegheny woodrat (, "A Rocky Existence: The Woodrat In Pennsylvania", https://en.wikipedia.org/w/index.php?title=Allegheny_woodrat&oldid=1012378167, Articles with dead external links from October 2018, Articles with permanently dead external links, Short description is different from Wikidata, All articles with vague or ambiguous time, Vague or ambiguous time from September 2012, Articles with unsourced statements from May 2013, Creative Commons Attribution-ShareAlike License, This page was last edited on 16 March 2021, at 01:49. The surrounding forest is usually deciduous. Neotoma magister. Unusual items that have been found in nests include bits of glass, bones, clothing, flash bulbs, paper, metal scraps, and shotgun shells. [11], They very rarely travel more than a few hundred feet from their home ranges. Fossils belonging to the species are known from mid Pleistocene deposits in Maryland and West Virginia. The Allegheny woodrat is a small rodent (about the size of a squirrel) that resides in rock outcrops, boulder fields, abandoned mine portals, talus slopes, and caves from southern New York to Tennessee (Wood 2001). The Allegheny Woodrat is a "pack rat" which are very similar in appearance to Eastern Woodrats, occur in the central part of Tennessee north of the Tennessee River.. Gestation lasts 30 to 36 days, and results in the birth of a litter of one to four young (typically two)[13][14], The young are born hairless and blind, weighing 15 to 17 g (0.53 to 0.60 oz). Digital Media Library, Office for Environmental Programs Outreach Services, College of Agriculture, Food and Environment. This includes buds, leaves, stems, fruits, seeds, acorns and other nuts. [4], They also collect and store various non-food items such as bottle caps, snail shells, coins, gun cartridges, feathers, and bones. Food is stored or "cached" in large piles called middens. They store their food in caches and eat about 5% of their body weight a day. An additional set of radiographs are scheduled for later this month. Female Allegheny woodrat (Neotoma magister) with newborn babies (photo by K. LoGiudice). [3] However, these contract dramatically in the late fall and winter, when little fresh food is available, and they rely instead on their caches to survive. Predation by great horned owls has also been cited. The name “woodrat” unfortunately causes some people to associate woodrats with the accidentally introduced Eurasian rat. It avoids people and rarely inhabits areas near the human settlements. Allegheny Woodrat or Pack Rat (Neotoma floridana) The mysterious decline of Allegheny woodrat populations throughout eastern North America has been the focus of much research in recent years. The Allegheny woodrat (Neotoma magister), is a species of "pack rat" in the genus Neotoma. The breeding season is variable across their range, but is broadly between March and October, and they average two or three litters per year. Allegheny woodrats prefer rocky outcrops associated with mountain ridges such as cliffs, caves, talus slopes, and even mines. Woodrats prefer to inhabit cliff line or boulder fields with complex, small tunnel systems. The whiskers are unusually long, typically over 5 cm (2 in) in length. A video by: Lisa Gong, Jana Suriano, and Thomas YetterThe Allegheny woodrat is an endangered rodent that lives in the northeastern United States. Seasonal Changes - Active through all seasons. Mast producing trees are important food sources. [12] The gland becomes particularly prominent around the breeding season, and is said to produce a strong odor. Another frequently cited cause is near total loss of American chestnuts caused by chestnut blight and of defoliation of oaks by an invasion of gypsy moths (lowering available supplies of acorns for woodrats). (14 – 21 cm) tail length; 1.3 – 2 in. Adults typically range from 31 to 45 cm (12 to 18 in) in total length, including a tail measuring 15 to 21 cm (5.9 to 8.3 in). The latter job is an amusing version of whack-a-mole with heads dipping into the spaces between rocks only to pop up a moment later and relocate to the next potential cache or latrine area. Status - Listed as partial status (PS) under the Federal Endangered Species Act; meaning the status applies to the species in only a portion of its range. In Virginia and West Virginia, woodrats are found on ridges, but also on side slopes in caves and talus (boulders and breakdown) fields. Increased competition for acorns with overabundant white-tailed deer, and increasing populations of black bear and turkey may also have a negative impact on woodrat survival. They do not need to drink since they get enough water from their food. Fun Facts - Woodrats do not hibernate but will stay in the nest for long periods of time. Dusky-footed woodrats are chiefly herbivorous, but will eat insects, especially mealworms and crickets if offered; they eat a variety of cuttings from branches, leaves, fruits, and nuts. Woodrats are a major part of the diet of many meat eaters. The woodrat is as rare as the Norway rat is common; the woodrat is a Predators of the woodrat include bobcats, coyotes, gray fox, hawks, snakes, weasels, and owls, such as great horned owl and barred owl. Adults Food items include various fruits, nuts, vegetation, and fungi (Balcom and Yahner 1996). All woodrats are vegetarian, and three species exhibit dietary specialization: Stephen’s woodrat (N. stephensi) subsists almost entirely on juniper sprigs, and N. albigula and N. lepida feed mostly on prickly pear, cholla cacti, and yucca plants. [3], It is the second-largest member of the native North American rats, and can weigh up to a pound, roughly the size of an eastern gray squirrel.[4]. They become fully furred at two weeks, and open their eyes at three weeks. They are comparing modern DNA to historic DNA from museum specimens as a way to characterize remnant genetic diversity in the species. Allegheny woodrats occur along mountain ridges in barren rock outcrops, caves, cliffs, and talus fields. The woodrat is also known as a packrat because it collects objects and takes them back to the nest. Individual woodrats build a nest of plant material within a rock outcrop and may surround the nest with dry leaves and twigs, possibly as an alarm system. It’s difficult for a population to persist when its main food source has disappeared. In parts of their range (New York, New Jersey, and Pennsylvania), the Allegheny woodrat population has been in decline over the past 30 years. Males weigh 357 g (12.6 oz) on average, while females are slightly smaller, weighing an average of 337 g (11.9 oz). Allegheny woodrats are primarily herbivores and eat a variety plants, berries, fruits, and seeds. [2], The Allegheny woodrat is a medium-sized rodent almost indistinguishable from the closely related eastern woodrat, although slightly larger on average, and often with longer whiskers. Predators of the woodrat include bobcats, coyotes, gray fox, hawks, snakes, weasels, and owls, such as great horned owl and barred owl. The reasons for the decline are not yet entirely understood, but are believed to involve a combination of factors. They are mainly vegetarians and feed on a wide variety of … The Allegheny woodrat (Neotoma magister) was once considered a common resident of Pennsylvania’s mountains. They are also conducting[when?] & NatureServe (Hammerson, G., Whittaker, J.C. & Norris, S.J.). field searches for new localities and research to identify the factors for decline. [7] These rats form small colonies in which their nesting areas consist of a network of underground runways and many conspicuous latrines. Description - Soft, gray fur, white belly and feet; hairy tail having two colors: gray above, white underneath; short toes and claws; large eyes & ears; long whiskers; skull has 16 teeth, Size - 12.6 – 18.8 in. Extension / This trait is responsible for the nickname "trade rat" or "pack rat". Woodrats are a major part of the diet of many meat eaters. The Division of Wildlife’s mission is to conserve and improve fish and wildlife resources and their habitats for sustainable use and appreciation by all. For example, vertebrate animals have a vertebral column, mammals produce milk to feed their young, and so on. They unknowingly provide food for other animals since their food store (cache) is vulnerable to being stolen. Philanthropy & Alumni The Allegheny woodrat is nocturnal and active year-round. [5] In some cases, researchers have found dried leaves placed around the nesting area which appear to act as alarms to warn the rats of approaching danger. Their diets primarily consist of plant materials including buds, leaves, stems, fruits, seeds, acorns, and other nuts. Their bulky nests provide shelter for many other animals such as snakes, toads, salamanders, and rabbits. If the Allegheny woodrats contract raccoon roundworm, a parasitic worm that lives in the intestine, it destroys their nervous systems. Fun Facts - Woodrats do not hibernate but will stay in the nest for long periods of time. spent shell cases and candy wrappers) further … [10] They are generally quiet animals, but have been reported to make "squeaking" and "whimpering" noises in captivity. This is mostly true for Pennsylvania and Maryland. The veterinary team will continue to monitor this young woodrat.
