| We are a juridical non-profitable organization, managing sika deer as local natural resource in Nishiokoppe Special Hunting Area in Nishiokoppe Village, Hokkaido, Japan. We aim to reduce deer-caused agricultural and forestry damages by hunting management of deer, to enhance hunter education, and to contribute to the local economy by sustainable use of deer. We also use the non-consumptive values of wildlife by educational program about local wildlife and nature. | ![]() |
Background
Hokkaido sika deer (Cervus nippon yesoensis) have increased explosively in last two decades without important predators.
Agricultural and forestry damages caused by them amount to several billion
yens annually. Although Hokkaido government has tried to reduce deer population
under the deer management plan since 1998, sika deer are still overabundant.
Although the authorities depend on sport hunting and nuisance control kill
by general hunters for capturing deer, reduction of the number of hunters
and the aging are progressing. While sika deer potentially have consumptive
and non-consumptive values as natural resource, e.g. game, meat, skin,
and viewing, the values are not recognized sufficiently because hunting
and consumption of game meat etc. are not so popular in Japan, traditionally.
Local deer management in view of resource use and promoting hunting are
necessary for human-deer coexistence.
Nishiokoppe Spetial hunting Area
A local sika deer management has started in Nishiokoppe Village, Hokkaido.
A special hunting area (SHA) was established in the whole of the village
(308 km2) in 2004, based on
the law of wildlife and hunting. This is the only SHA in Hokkaido. Kinds of
game animals, quota, number of hunters per day, etc can be regulated uniquely
in a SHA, differing from general hunting areas. The management objectives of the
Nishiokoppe SHA (NSHA) are 1) to control the local deer population for
reduction of agricultural and forestry damages by deer, 2) to realize safe and
easy hunting for hunters and the residents, 3) to contribute to local economy
by consumption and accommodation of hunters and by employment of guides, 4) to
conserve native hunting culture and to educate hunters. The activities are 1) monitoring
deer population, 2) guided hunting, 3) hunting school for inexperienced
hunters, and 4) general education about wildlife and hunting.
Nishiokoppe Village
Nishiokoppe
Village, 44°12’-44°26’
N and 142°48’-143°04’
E, is located at eastern Hokkaido Island (Fig. 1) and occupies 308 km2.
The population of the residents is approximately 1,200 and the key industries
are dairy and forestry. The temperature annually averages 5℃
and ranges from -20 to 30℃. The maximum snow depth is less than 100 cm. The
annual precipitation is approximately 1050 mm. The elevation ranges from
60-1142 m. Forests occupy 89% of the whole village. The major vegetation is
mixed forest with evergreen conifers and deciduous broad-leaved trees. The dominant
tree species are Acer mono, Tilia japonica, Quercus crispula, and Abies
sachalinensis, with undergrowths of Sasa spp. Plantation forests composed of Abies sachalinensis and P.
glehnii are scattered. Agricultural lands occupy 5% of the whole village
and mainly include pastures.

Organization
Nishiokoppe
Wildlife Association (NWA) manages NSHA and is a juridical non-profitable
organization. NWA consists of local hunters, members of a deer farming group, a
village hotel, and others. Nishiokoppe Wildlife Steering Committee supervises
NWA and consists of the village office, a local forestry association, a local
farmers association, a local chamber of commerce and industry, a local hunting
club, a local police, a local Hokkaido forestry office, a natural environmental
clerk of sub prefecture office, and so on. Thus, local agreements are taken
into consideration.
Monitoring
Harvest data and spotlight survey data in the village by Hokkaido Government
(HG) are available for more than 10 years. HG collected harvest data by
questionnaire survey. NWA collected all harvest data directly since 2004/05.
Spotlight surveys were conducted in a day in October for 20 km by HG and
intensively in each 3 days in April and October by NWA. We survay deer
infectious disease e.g. hepatitis E with Hokkaido University.
Guided hunting
In NSHA, hunters must get the hunting permissions, which limited to at most six hunters in two groups per day, and must employ a guide per less than three hunters. The guides are local hunters that are familiar with the deer status, the topographies, and the land use of the residents in the area. A comfortable dressing and processing facility is available in the village. These contribute to security in firing, the increase of the capturing efficiencies,
and proper treatment of deer carcasses. Hunting quota per two days was two deer in the 2004/05 season, while two stags could not be shot in a day.

In the first season between October 25 in 2004 and February 28 in 2005, the entries in NSHA amounted to the total of 44 hunter-days by 13 hunters, including hunting school. Seven of the 13 hunters came from out of Hokkaido Island, mainly Kanto Region. Five of six hunters from Hokkaido Island were beginners. Thirty-eight deer, 27 stags and 11 hinds, were shot, including two by hunting school. The rates of capture success (RCS) were 91%, 67%, and 86% in rifle users, shotguns users, and the total, respectively (Table 1). CPUE were 1.48, 0.67, 0.86 in the same sequence (Table 1).
| Firearm | RCS* | CPUE** | SPUE*** |
| Rifle | 91% | 1.48 | - |
| Shotgun | 67% | 0.67 | - |
| Total | 86% | 0.86 | 16.2 |
*The rate of capture success was the percentage of whether a hunter succeeds
in capture deer in a visit in NSHA.
**Catch per unit effort (CPUE) was the number of deer harvested per hunter-day.
***Sight per unit effort (SPUE) was the number of deer sighted per hunter-day.
Hunting school
In order to educate inexperienced hunters who assume the wildlife management,
four courses of hunting school were held in 2004/05. The curriculums included
lectures of wildlife biology, wildlife management, preparation of hunting
equipments, and hunting techniques, and practices of shooting, hunting,
dressing, processing, and cooking.
The total of 37 people participated in the four courses in 2004/05, including
seven beginner hunters and five children. Two deer were captured by beginners
in the practices of actual hunting in the 3rd and 4th courses (Photo 2).
