Lepus coreanusKorean hare

Geographic Range

The geographic range of Lepus coreanus, also known as the Korean hare, includes the entire Korean Peninsula as well as southern Jilin Province and northeastern parts of China. (Smith and Xie, 2008)


Korean hares occupy various habitats across their geographic distribution, from plains to mountains, preferring areas where vegetation is abundant. A study conducted in Mt. Chirisan National Park, South Korea indicated that L. coreanus abundance was positively associated with the percent of shrub cover in a given landscape. Korean hares can live in a variety of areas, including cultivated lands, plains, scrublands, and forest areas. (Flux and Angermann, 1990; Lee and Rhim, 2012; Smith and Xie, 2008; Smith, A.T. and Johnston, C.H., 2008)

Physical Description

Fur color in Korean hares varies, but is generally a brownish shade. The dorsal parts of the body are usually brown or grayish brown, and the ventral area is paler or white. An adult Korean hare weighs 2.1 to 2.6 kg, and has a body length of 45 to 54 cm. The tail is short, typically 2 to 5 cm in length with a black stripe located on the upper side in the middle, and the ears are 7.6 to 8.3 cm long. They have long ears and well-furred feet to aid in their ability to travel fast and cover vast areas in a short time period. Korean hares are born fully furred and with their eyes opened. They have very big eyes which allow for greater visual acuity in dim light. Male hares are slightly smaller than female hares. (Flux and Angermann, 1990; Nowak, 1999)

There is little known about mating in Korean hares, but there are many commonalities to mating within hares. Hares use scent cues secreted from special glands located under the chin and in the groin. These scent cues are believed to play a key role in sexual communication, as well as in signaling social status. Male Korean hares become bolder during the mating season, engaging in fights with other males and pursuing females. They fight by using boxing motions with their forefeet and kicking with their hind feet. (Macdonald, 2001; Nowak, 1999)

Korean hares have a long breeding season, which peaks in spring. Up to a dozen males congregate around a female in estrus, boxing each other and chasing off other rivals. The gestation period for most Lepus species is 42 days and the average litter size increases seasonally to a peak then declines; there are normally 3 to 5 litters per year. The annual production of young per female is about 10. (Flux and Angermann, 1990; Macdonald, 2001; Nowak, 1999; Flux and Angermann, 1990; Macdonald, 2001; Nowak, 1999)

Little is known about parental investment in Korean hares. However, male hares are not generally involved in caring for young. Maternal investment is also limited in hares. They engage in a reproductive strategy known as "absentee parenting." Nursing takes place once or twice a day, usually at night, and only lasts for just a few minutes. It is thought that the lack of social contact between the mother and her young is a strategy which diminishes the chances of attracting the attention of predators. (Macdonald, 2001)

The majority of Korean hares die within the first year of life in the wild because they are subject to high predation rates. In captivity, they have been reported to live to the age of 5. (Macdonald, 2001)

Little information on the behavior of this species has been reported. They typically travel in open habitats to feed during late afternoon or evening. They are not thought to be social and there is no indication of territorial behavior, but hierarchies do exist which affects access to food. Shrubs, bushes, and rocks are used as cover to protect these hares from predators. Korean hares occupy different habitats in regions where they overlap geographically with other hares and rabbits. The ranges of hare species are not static; one species can compete with another and exclude it from its former habitat if ecological conditions change. (Flux and Angermann, 1990; Smith, A.T. and Johnston, C.H., 2008)

Home Range

Home range size of Korean hares is not reported in the literature.

Communication and Perception

Details of communication among Korean hares have not been reported. In general, hares communicate with each other by drumming their feet and through scent cues. Female hares make a shrieking sound to call to the young for feeding times. (Flux and Angermann, 1990)

Food Habits

Korean hares are likely entirely herbivorous, similar to other hares. They eat many types of grasses and shrubs and will chew bark from trees. (Flux and Angermann, 1990)

  • Plant Foods
  • leaves
  • roots and tubers
  • wood, bark, or stems
  • flowers


Korean hares use speed and agility to avoid becoming prey to predators. They also camouflage themselves by flattening out among vegetation. Gray wolves and red foxes are known predators of Korean hares. Other possible predators are large raptors and snakes. They are also well-known game animals and trapped by villagers for food. (Flux and Angermann, 1990; Macdonald, 2001; Nowak, 1999)

  • Anti-predator Adaptations
  • cryptic

Ecosystem Roles

Korean hares act as both important prey items for many species and, as herbivores, act to control plant growth and disperse seeds and nutrients. Hares can be most selective in eating grass seed-heads, but whether this curtails or increases the spread of these grasses will depend on the relative number of seeds digested and passed through the animal. In hilly country, these herbivores eat at the bottom of the valley floors and defecate while traveling back and forth from their daylight habitat several hundred meters uphill. Thus hares actively reverse the normal downhill flow of nutrients in an ecosystem. (Flux and Angermann, 1990; Nowak, 1999)

  • Ecosystem Impact
  • disperses seeds

Economic Importance for Humans: Positive

Korean hares are trapped by villagers for food and fur. (Nowak, 1999)

  • Positive Impacts
  • food
  • body parts are source of valuable material

Economic Importance for Humans: Negative

Korean hares are considered "pests" in agricultural regions because they may forage on crops. They are thought to pose a problem to barley growing near the mountains in Kyeonsnam Province and sometimes girdle fruit trees. (Flux and Angermann, 1990; Nowak, 1999)

  • Negative Impacts
  • crop pest

Conservation Status

There are no known conservation measures in place for this species. It is not known if this species is present in any protected areas. In China, this species has been regionally Red Listed as Least Concern. (Smith and Xie, 2008; Smith, A.T. and Johnston, C.H., 2008)

Other Comments

Korean hares are an example of Bergmann's Rule - where larger species within a genus occur at higher latitudes. Hare species in the far north weigh around 5 kg, most species in temperate regions average 3 kg, and species occurring near the equator are 2 kg or less. However, even within this genus there are exceptions to this rule. (Flux and Angermann, 1990)
