The Japanese serow (Capricornis crispus or Naemorhedus crispus; Japanese: Nihon kamoshika (ニホンカモシカ)), is a goat-antelope found in dense woodland in Japan, primarily in northern and central Honshū.

Adult Japanese serow stand about 81 centimetres (32 in)[2] and weigh 30–45 kilograms (66–99 lb) They are mottled brown and white and black underneath. Their fur is very bushy, especially the tail. Both sexes have short 10-centimetre (3.9 in) horns, which curve backwards. Japanese serow are found in dense hillside forests where they eat leaves and acorns. They are diurnal, feeding in the mornings and evenings and resting under rock ledges for the remainder of the day. The serow are solitary, or gather in couples, sometimes with kids as well. Generally they live in small ranges, around 20,000 square metres for individuals and up to 200,000 square metres for larger groups. Ranges are marked with a substance similar to vinegar that is secreted from the serow's preorbital gland, which is just in front of the eye.

The Japanese serow was hunted to near-extinction until the Japanese government in 1955 passed laws protecting it from poachers. Populations have grown so greatly that IUCN Red List of Threatened Animals ranks it "Least Concern". Complaints of foresters and farmers led in 1979 to a repeal of the 1955 law, since whichit has had protected status in 13 designated protected areas over 23 prefectures.

Description

Japanese serows

The Japanese serow (Capricornis crispus, sometimes Naemorhedus crispus;[1] Japanese: [kamoshika] Error: {{Lang}}: text has italic markup (help))[a][3] is a small bovid[4] that stands about 81 centimetres (32 in)[2] and weighs 30–45 kilograms (66–99 lb).[4] It typically has a longer, woolier coat—about 10 centimetres (3.9 in) on the body—and shorter ears than mainland serow. It has a bushy tail and no mane. Its black-to-dark brown coat lightens in summer.[2] Both sexes have short horns,[5] and differences between the sexes are not well developed.[1] It can tolerate colder, snowier climates than mainland serows.[5]

The Japanese serow lives up to 20 years. It feeds on alder, sedge, Japanese witch-hazel (H. japonica), and cedar. It has few predators, as Japanese wolves have become extinct; bears may prey on them. They flee with a whistling snort when they detect danger.[5]

Taxonomy

There is no fossil record of the Japanese serow; its evolutionary history and relation to the Taiwan serow are speculative.[4]

Distribution, ecology, and behavior

Japanese Serow outside of Wakinosawa, Aomori

Capricornis crispus is endemic to three of the four main islands of Japan: [3] primarily northern and central Honshū, and in small areas in Shikoku and Kyūshū.[3] It lives in open grassland and forests at an elevation of about 1,000 metres (3,300 ft);[2] it prefers temperate deciduous forest, but also lives in broad-leaved or subalpine coniferous forest, alpine meadow, and coniferous plantations.[1] Popualation density is low at an average of 2.6 per square kilometre (6.7/sq mi).[1]

The diurnal Japanese serow feeds in early moring and late afteroon, primarily on fleshy or coniferous leaves, plant shoots, and acorns.[1]

The Japanese serow is socially monogamous.[6] First breeding takes place at age 2.5–3 years; breeding occurs once a year.[5] Birth takes place between June and August. In a courtship ritual resembling that of goats or gazelles, the male Japanese serow licks the female's mouth, strikes her on the hindlegs with his forelegs, and rubs her genitalia with his horns.[2] After a gestation period of about 210–220 days[7] birth takes about half an hour, as the female walks about. The single young is 30 centimetres (1 ft) tall and reaches adult height in a year.[5]

Conservation

An animal that once inhabited deep forests far from populated areas, the Japanese serow has increasingly penetrated the outskirts of villages.[8] It had been hunted to such a severe degree that in 1934 the Japanese government declared it a natural monument for its protection. Poaching continued, so in 1955 the government declared the Japanese serow a special natural monument,[3] at which point overhunting had brought its numbers to 2000–3000.[2] Populations grew as the police put an end to poaching, and post-War monoculture conifer plantations created favourable environments for the animal. By the 1980s, populations estimate had grown to up to 100,000 and serow range had reached 40,000 square kilometres (15,000 sq mi).[3]Conflicts with agriculture and forestry led to the repeal of the full protection the animal received under the 1955 designation. Thenceforth 13 designated protection areas were established over 23 prefectures. The IUCN Red List of Threatened Animals ranked the Japanese serow as "Lower Risk" in 1996.[9]

Foresters have raised concerns that the rising serow populations have interfered with post-War mountainside reforestation efforts, as the animal feeds on the saplings[10] of Japanese cypress, Japanese cedar, and Japanese red pine, species with commercial significance.[3] Mountain villagers have objected to conservationists' efforts, and damage by serows to forests has been characterized in parts of Japan in criminal or martial terms: the media have referred to the problems as [ningen to shika no sensō] Error: {{Lang}}: text has italic markup (help) ("the war between humans and deer") and [kamoshika sensō] Error: {{Lang}}: text has italic markup (help), ("serow war"). Foresters in Gifu Prefecture have justified the shooting of serows in the legs, as such shooting would not be fatal.[11] Estimating accurate population numbers has been difficult.[12] Foresters see the serow as a harmful animal, and resent government interference in controlling serow-hunting.[13] They have accused the government and wildlife experts of undercounting serows, while conservationists have counteraccused that foresters may inflate population numbers and levels of forestry damage to promote their own interests.[12]

Conservationists such as Shin Gotō believe that the increased visibility is due not to an absolute increase in populations, but to deforestation which has driven the animal further from its traditional home.[12] Serows close to populated areas may feed on farms and cypress, including saplings.[14] Clearcutting practices may also contribute the problem, as clearcut forests create areas of rapid herbaceous growth ideal for herbivores, who see population increases. The situation is temporary, though, and after regrowth of trees leads to the forest canopy closing over after 15–20 years the herbivore populations are displaced as the herbaceous growth ceases to flourish.[14]
