천연기념물의 명칭 부여 및 지정 물량을 포함한 현재의 천연기념물 관련 체계는 일제강점기에 도입된 '조선보물고적명승천연기념물보존령' (1934)을 기반으로 하고 있으며, 이에 따른 골격이 지금까지 그대로 통용되고 있다는 문제점이 지적되고 있다. 당산숲 비보숲은 우리나라 농어촌의 숲문화를 대표하는 전통문화자원이며 국가적 문화자산이다. 천연기념물을 포함한 당산숲 비보숲을 논할 때 천연기념물 등에서 사용하는 "명칭", "분류 체계" 등에 대해서 문화재청에서조차, '조선의임수(朝鮮の林藪)' (1938)라는 일제의 조사보고서에 실린 내용에 전적으로 의존하고 있다는 것이 근본적인 문제점이라고 할 수 있다. 즉, 일제가 1938년에 '완도 예송리 당산숲'을 '례송리상녹수림(禮松里常綠樹林)'이라고 이름을 붙인 후, 현재까지도 우리 농어촌의 당산숲 비보숲을 천연기념물 등으로 지정할 때, 해안가의 경우 대부분 일제가 한 방식대로 '~상록수림'이라는 명칭을 그대로 따르고 있다는 것이 대표적인 예이다. 본 논문의 목적은 천연기념물 제도의 출발점인 일제강점기의 '조선의임수(朝鮮の林藪)' 등 일본 자료에 대한 문제점을 고찰하고, '조선의임수(朝鮮の林藪)' 등의 논리를 우리의 당산숲 비보숲 등에 여과 없이 적용시키고 있는 현 상황을 개선하는 방안을 찾고자 하는 것이다. 이를 위해 천연기념물로 지정된 수림지, 노거수 중에서 당산제를 지내는 당산숲이 있는 18개소를 선정하여 조사, 분석하였다. 결과로서, 천연기념물로 지정된 많은 수림지, 노거수 중에서 그것이 당산숲, 당산나무라면 "~당산숲", "~당산숲과 비보숲", "~당산나무"라는 명칭을 일관성 있게 부여해야 할 필요가 있다는 것을 제안하고자 한다. 이러한 조치가 이루어지면 일제강점기에 도입된 천연기념물 제도의 한계를 극복하는 출발점이 시작될 수 있으며, 우리나라 전통조경 양식 및 문화경관으로서의 당산숲에 대한 위상이 제고될 수 있을 것이다.

Japan is one of the major forest-rich countries in the world with two thirds of its national territory covered with forests. The various functions of forests, including the prevention of global warming, conservation of national land, recharging of water resources, and maintenance of biotic diversity, play an important role in our safe, secure, and comfortable living. With the increasing national expectations on the role of forests to contribute to the prevention of global warming and "Accelerating forest carbon-sink measures to achieve Kyoto Protocol Commitment", it is necessary to make efforts toward a large-scale forest regeneration in order to secure an absorption of 13 million carbon tons through forest carbon sink for the achievement of the target of six percent reduction under the Kyoto Protocol. Most importantly, however, is to accelerate the measures for forests as absorption sources, including thinning and other forestry management activities. However, there is a situation, among others, where thinning is not implemented properly due to the decreased willingness of forest owners to manage forests, because of the long-term low demand for domestic lumber and lumber prices. In addition, forestry workers are aging and decreasing in number. Thus, the circumstances surrounding forestry are severe. It is necessary for the protection of our precious forests to make efforts to create and maintain forests with activities that involve citizens such as the "National Movement for Utsukushii Mori Zukuri(Fostering Beautiful Forests)".

This research was carried out to investigate soil mictoarthropods fauna in Namsan and Kwangreung which were considered to receive different degreeds of environmental pressures. In basic environmental data, Namsan where under rather accelerated acidification by air contamination and acidic rain showed low pH, tardy decomposition and turnover rate. Population density of soil microarthropods was high in Kwangreung 17,169.8/\ulcorner\ulcorner(coniferous forests), 17,892.6/$\textrm{m}^2$(deciduous forests) than in Namsan, 12,143.8/$\textrm{m}^2$ (coniferous forests), 14,216$\textrm{m}^2$(deciduous forests). Biomass of soil microarthropods was 2,020.219mg/$\textrm{m}^2$ at coniferous forests and 4,270.172mg/$\textrm{m}^2$ at deciduous forests in Namsan, and 3,287.326mg/$\textrm{m}^2$ at coniferous forests and 4326.1mg/$\textrm{m}^2$ at deciduous forests in Kwangreung. Population density constantly showed high in spring, and seasonal fluctuations were correlated with seasonal precipitation. As far as vertical distribution is concerned, population density was concentrated in litter layer as 70% while 30% are in soil layer and also decreased with increasing depth.

The study investigates herbage communities along the altitudinal gradient in northwest Himalaya and highlights the effect of trees on its understory floristic diversity and phytosociology. The study was conducted in nine forests at three elevations viz., chir pine (Pinus roxburghii), mixed and khair (Acacia catechu) forests at elevation $E_1$ (850-1150 m), chir pine, mixed and ban oak (Quercus leucotrichophora) forests at elevation $E_2$ (1151-1600 m) and ban oak, mixed and chir pine forests at elevation $E_3$ (>1600 m) in a sub-watershed located in Solan district of Himachal Pradesh, India. These were compared grasslands located adjacent to forests. In all, 20 grass, 3 sedge, 2 forb and 4 legume species were recorded in study sites. Jaccard's coefficient of herbage vegetation was highest between chir pine forests and grasslands, and lowest in khair and ban oak forests. TWINSPAN dendrogram of herbage composition exhibited three subtypes with Apluda mutica, Arundinella nepalensis and Dichanthium annulatum as indicator species. Three groups of plant communities were identified on the basis of their moisture requirement. Peak density and basal area of herbage in forests and grasslands occurred by September. Density and basal area of herbage in grasslands at different elevations ranged from 649.6 to $1347.9tillers/m^2$ and 30.0 to $65.7cm^2/m^2$, respectively, while, in forests it varied from 351.2 to $1005.3tillers/m^2$ and 14.9 to $43.9cm^2/m^2$, respectively. Density and basal area of the herbage in plant communities decreased along the elevation. Under trees in forests the density of herbage decreased up to 77% and basal area up to 62% of their respective values in grasslands.

This study aimed quantitatively to estimate the recent level of recognition of the public value of forests in Korea, to analyze the factors that affect their value, and to present implications. The average annual payment regarding the public value of forests estimated using the contingent valuation method was 234,170 won, broken down into 12 functionalities. The Tobit model was used to analyze demographic factors affecting the degree of willingness to pay, and the analysis showed that area of residence, age, marital status, occupation, household income, and visits to forest facilities all had statistically significant impacts on the degree of willingness to pay. Among these variables, living area (living in Seoul), marriage status (married), occupation (professional and office workers), and household income (more than the median income) were found to have a positive relationship with the degree of willingness to pay, while age and the number of visits to forest facilities were found to have a negative relationship. The implications are as follows: First, it is necessary to establish and implement policies to enhance positive perceptions of the various functions of forests and the legitimacy of protecting forest resources, considering that the public's valuation of various public functions provided by forests is directly related to changes in perception. Second, public evaluations of the public value of forests remain at a low level, meaning that education and promotions regarding the public value of forests need to be implemented and strengthened in the future. Finally, in order to form a consensus among people on the public functions of forests, customized promotions and educational events need to be implemented for non-Seoul residents, non-professionals, the unmarried, and for those who regularly visit forests.

Rural areas dominate country landscape, where the population is rich in traditional and natural heritage. Dangsan forests and Rural community forests (RCF) have been maintained by local residents for hundreds of years. However, many of these forests have been disturbed, and only small amount of Dangsan forests and the RCF remain due to the efforts of local residents. Recently, the remnants of Dangsan forests and RCF have been regarded as living traditional landscapes representing the cultural and rural background of Korea. But the value of Dangsan forests and the RCFs has not been recognized by many. This study aims to understand the characteristics and management status of Dangsan forests in Sungnam-ri, Wonju. Sungnam-ri has four villages, each of which is bordered by a Dangsan forest at the riparian buffer. Sungnam-ri has been selsected as a site for a rural village development project by the Ministry of Agriculture & Forestry of Korea. Sunghwanglim (the Upper Dangsan forest) is designated as Natural Monument No.93 and entrance is limited in this area. The size of Sunghwanglim is $21,133m^2$, and the major tree species are Kalopanax pictus (Dangsan tree, Divine tree), Pinus densiflora, Abies holophylla, Acer triflorum, Ulmus davidiana, Fraxinus rhynchophylla and Quercus serrata. In total, 124 trees with more than 40 cm in DBH are at this site. As for cultural activities, the Dangsan festival is held on April 8th and September 9th of the lunar calendar at shrines in the forests. Although other Dangsan forests are smaller than Sunghwanglim, they also have similar cultural activities. The landscape of the Dangsan forests have been managed for several hundred years by the local people, and they intend to continue maintaining the Dangsan forests for the purpose of festivals and other cultural activities. The findings in this study suggest that Dangsan forests have the potential for the development of rural villages and for the improvement of cultural and natural landscapes in Korea.

Feeding behavior of the Russet Sparrow Passer rutilans was studied in two different types of habitats, shelter belts and isolated forests, in south-eastern Hokkaido, Japan, during the breeding seasons of 1995 and 1996. Predominant foods were determined as Caterpillar, Coleoptera, Diptera, Ephemeropera, Odonate and some other insects. The composition of the nestiling foods were not the same by season, region, and year. Larger foods in size were used by birds in isolated forests more frequently than in shelter belts. Amount of food per feeding was significantly larger in isolated forests than in shelter belts. Although food supply were more abundant in isolated forests than in shelter belts, the feeding frequency did not significantly differ between these two habitats. The nest density was higher in isolated forests than in shelter belts. Results of this study indicate that when the feeding condition is poor, birds tend not show specific food selection behavior, the feeding range is therefore larger, and the feeding interval is longer. Contrarily, the birds show a specific food selection behavior when they are in good feeding condition, the feeding range is therefor smaller and the feeding interval decreases.

To account for the importance of variable in multi-sensor data fusion, random forests are applied to supervised land-cover classification. The random forests approach is a non-parametric ensemble classifier based on CART-like trees. Its distinguished feature is that the importance of variable can be estimated by randomly permuting the variable of interest in all the out-of-bag samples for each classifier. Supervised classification with a multi-sensor remote sensing data set including optical and polarimetric SAR data was carried out to illustrate the applicability of random forests. From the experimental result, the random forests approach could extract important variables or bands for land-cover discrimination and showed good performance, as compared with other non-parametric data fusion algorithms.
