  • In the United States, forest administration is a constantly changing complex of policies, programs, and management regulations. Forest administration is the product of a brief but tumultuous history during which much of the forests which once covered half the land were coutover for farms, industry, and cities. In the last 15 years, forest administration has been increasingly dominated by concerns for maintaining an ecological balance. Current forest administration is deeply rooted in the American traditions of decentralized federalism and free enterprise, yet combines state socialism and private capitalism. The major elements of U.S. forest administration consist of : 1) programs and policies on taxation, professional education and research, and "cooperative forestry", 2) state controls on forest practices for privately owned lands, and of federal policies and regulations for the management of federal lands. The federal Forest Service has played a lead role in developing and implementing national forest policies and programs. Since the end of World War II, the national forests managed by the Forest Service for multiple use have provided and ever growing fraction of domestic timber needs. In the coming decades, cultural and social trends may force a change in management policy on federal land, reducing the importance of timber harvesting in relation to amenity values.

  • Korea is a small country with extremely high population density. Industrialization of the nation resulted GNP per capita of over 2,000$ in 1986 with an inevitable by-product, high level of pollution in many areas. Forest land is now acknowledged as not only a wood production site but also an origin of much more important intangible values, water and clean air, soil conservation, and recreational and scenic values. Mostly devastated forest land from Korean War has been recovered under the strong afforestation drive from the government. The first Forest Development Plan was mostly reforestation phase and the second Forest Development Plan is foundation establishment phase. The third and later Plans are to enlarge economical forest and to maintain sustatined yield phase. Forestry administration as well as forest research certainly played a great role in successful accomplishment of two Forest Development Plans. For effective planning and accomplishment of the third Forest Development Plan close cooperation among policy makers, forest managers and research workers are mostly required.

  • 생산성이 높고 가시가 없는 초피나무의 2단계 대량증식이 가능하였다. 기내 줄기의 생장에는 대체로 DKW 배지가 좋은 반등을 보였으며, 수평으로 120$^{\circ}$각도를 준 플라스틱 Petri dish에서 다경 줄기를 유도할 때에는 BAP 0.89 $\mu$M이 적당한 것으로 나타났다. 다경 줄기를 유도한 후, 수직으로 세운 Petri dish의 윗면에 5-7개의 구멍을 낸 다음, 30% 정도의 빛만 투과할 수 있는 조건의 온실에서 환경순화를 시켰다. 이들 다경 줄기의 기저부를 제거한 다음 각각의 줄기를 피트 플러그에 이식한 결과, 100%의 발근율을 얻었다. 폿트에서 약 6개월 가량 유지하였을 때에도 선발목에서와 같이 줄기에 가시가 형성되지 않았으며, 향후 생산성에 대한 검정이 이루어지면, 조직배양에 의한 실용화가 가능할 것으로 생각된다.

  • 현사시나무 4배체의 약배양에 의하여 2배체 식물을 얻을 수 있었다. 약배양에 의한 캘러스 유도에는 2,4-D가 효과적 인 것으로 나타났다. 증식된 캘러스로부터 식물체 재분화를 위해서는 16시간의 광조건하에 6-8 $\mu$M의 zeatin 처리가 가장 좋은 반응을 보였는데 이때 얻어진 줄기수는 평균 7.7개 였다. 재분화된 식물체는 MS 기본배지에서 쉽게 뿌리를 유기시킬 수 있었으며, 이들 식물체는 폿트묘로 육성하여 온실 및 포지로 이식하였다. 약배양유래의 300클론에 대한 생육상태를 조사한 결과 삽목묘에 비하여 33%는 생장이 저해됨을, 47%는 생장이 더 좋은 것으로 나타났으며, 그중 20%는 삽목묘에 비해 직경이 5배 이상되는 거대 엽을 가지고 있었다. 염색체 수는 대체로 2배체성 혹은 4배성을 띠고 있었으며, RAPD marker를 이용하여 DNA polymorphism을 본 결과 약배양 유래의 몇몇 식물체에 있어 서 밴드 형태적인 차이를 나타내는 개체를 발견할 수 있었다.

  • 이 연구의 목적은 통합적 산불관리에 있어서 협력을 형성 촉진시키는 요인을 구명하고, 이를 통해 효율적 산림관리를 위한 협력프로세스 및 협력 매뉴얼을 제시하는데 있다. 이를 위해 행정구역 단위를 초월하여 협력함으로써 큰 성과를 거둔 "동해안 산불관리센터"와 "지리산권역 산불관리센터"를 모델로 하여 각 단계별 협력요인을 추출하였다. 즉, 협력의 단계를 발의 계획 집행 이익의 공유 4단계로 나누고 통합 산림관리체계를 위한 각 단계별 협력요인을 추출하기 위해 심층면접 및 설문조사를 실시하였으며, AHP분석을 사용하여 중요도 순에 따른 핵심 4요인을 단계별로 추출하였다. 최종적으로 각 단계별 핵심 4요인을 바탕으로 산림협력 사업에 적용할 수 있는 협력 프로세스 및 매뉴얼을 개발하였다. 이는 지자체간의 협력을 통한 제반 산림관리를 성공적으로 추진하는데 있어 하나의 가이드라인이 될 수 있을 것이다.

  • The traditional village forests in Korea such as Dangsan forests and Bibo forests form unique cultural landscape and they are national cultural assets with histories of more than several hundred years. It is important to have sustainable right to enjoy cultural heritage as well as maintaining its authenticity. Cultural assets are meaningful only when they are managed to succeed to next generations. Dangsan forests and Bibo forests need to be named properly and recognized by society as a precious cultural heritage for many generations to come in order to claim the value as traditional cultural landscapes in Korea. The traditional village forest in Dangin-ri, Wando-gun was composed of a Dangsan forest and five Bibo forests. Although this traditional village forest is large in size, it was not on the report of Cultural Heritage Administration(2005) investigated for 'Village forest of island region in Jeollanam-do'. The objective of this study was to investigate the characteristics of the traditional village forest in Dangin-ri to grant correct name and to enhance its value. In this study the characteristics of a Dangsan forest and five Bibo forests were investigated from 2006 to 2013 for physical features such as size, shape, location, tree species composition, and diameter at breast height(DBH), as well as cultural aspects and tradition. Currently the naming and designation of natural monuments by the cultural heritage administration(CHA) is based on the rule enacted in 1934. Many Dangsan forests were named as evergreen forests. This type of names does not represent the meaning of traditional village forest. It was suggested that this traditional village forest is to be named as 'Dangsan Forest and Bibo Forests at Dangin-ri, Wando-gun'. This traditional village forest needs to reclaim authenticity and rebuild its original appearance by restoration of the disturbed areas, especially in Bibo forest I.

  • This article purposes to make a GIS database of South Korea rural village forest. So we first tried to collect data of their geographic coordinates or location from the many references on the rural village forest. As the result, we collected locations of the 634 forests. Boundaries of the 462 forests could be made by using their satellite imagery. Finally we implemented GIS database of the 462 traditional rural village forest in South Korea. Furthermore we surveyed 100 forests out of them. They were analyzed in the view of location, area, wood species, cultural assets and activities of inhabitants. These data can be used in the rural village planning and I look forward this database is helpful to preserve existing traditional rural village groves as a lasting legacy.
