To examine the natural regeneration in the natural mixed-broadlived forest, flowering, fruiting, seed-fall, and seed viabilities of Acer ukurunduense Trautv. & C.A. Mey. (AU) were investigated in Mt. Jungwang, Gangwon-do, from 2009 to 2013. The flower of AU consisited many male and bisexual flowers on the raceme (unusual panicle) and the arrangement of two sex morphs are differed for each inflorescence. Flowering dates are differed between sex morph in the same inflorescence. Stamens are stop growing and disappeared after pollinated pistil begin to grow in bisexual flowers, and male flowers have vestial pistil. The flowers of AU might be pollinated by Apis mellifera, Thyris fenestrella seoulensis, Cerambycidae sp., Andrenidae sp. and Ctenophora sp., and had some mechanism to prevent feom self pollination. The number of flower buds per inflorescence is 189 on June 8, and that of young samaras per inflorescence is 41.2 on June 21. At last ripened samaras per inflorescence is reduced 33.4 on September 5. Mean annual seedfall of AU was 6,720 ea/ha (ranged 670~17,930). Rates of sound seeds are highest 43.2%, and those of damaged or decayed seeds are 41.8%,. Those of undeveloped and empty seeds are 10.2% and 4.8%, respectively. Successful regeneration of AU might be in masting year and on the gap sites with proper conditions to germinate and grow. To understand the natural regeneration of the species, Genus Acer, further study on the fruiting habit, pre- and post-dispersal seed viability, and annual variation on these factor should be needed.

The objective of this study was to establish an open-field experimental warming treatment and precipitation manipulation system to simulate climate change impact for Pinus densiflora seedlings based on a climate change scenario in Korea. Two-year-old seedlings were planted in a nursery in April, 2013. The air temperature of warmed plots (W) was set to increase by
compared to control plots (C) using infrared lamps from May, 2013. The three precipitation manipulation consisted of precipitation decrease using transparent panel (-30%;
), precipitation increase using pump and drip-irrigation (+30%;
) and precipitation control (0%;
). Initially, the air temperature was
higher in warmed plots than in control plots and later air temperature was maintained close to the target temperature of
. The average soil temperature was
higher in warmed plots than in control plots. Also the average soil moisture content after the precipitation manipulation increased by 13.9% in
and decreased by 10.0% in
, and increased by 23.7% in
and decreased by 7.6% in
. It was confirmed that the open-field experimental warming and precipitation manipulation system was properly designed and operating.

DOI : 10.14578/jkfs.2014.103.2.165
This study was conducted to investigate composition of understory vegetation and indicator species by altitude and slope azimuth in Mt. Gyebang designated as Protected Area for Forest Genetic Resource Conservation and National Park. Tracheophytes were 350 taxa; 80 families, 203 genera, 303 species, 38 varieties, 5 forma and 4 sub-species in research area. The species of greatest importance value were Tripterygium regelii (9.143%), Acer pseudosieboldianum (7.594%), Symplocos chinensis for. pilosa (6.347%) in the shrub layer and were Sasa borealis (8.653%), Isodon excisus (2.936%) and Carex siderosticta (2.897%). In the herb layer as a result of NMS analysis, the distribution range of the major species were found to be affected by the altitude (shrub layer:
> 0.3, herb layer:
> 0.6). The result of plexus diagram analysis showed that Acer pseudosieboldianum was associated with Magnolia sieboldii, Acer barbinerve, Euonymus oxyphyllus etc. in the shrub layer; Meehania urticifolia was associated with Aconitum jaluense, Veratrum oxysepalum, Prunus padus etc. in the herb layer. The significant indicator species were analyzed for 60 species by the altitude and investigated for 30 species in accordance with the slope azimuth. As a consequence of MRPP, interspecies composition along the altitude group was heterogeneous and the species composition according to the azimuth slope was extremely different between the NE and SW.

Journal of Korean Forest Society, volume 103, issue 2, 2014, Pages 175~181
DOI : 10.14578/jkfs.2014.103.2.175
This study was conducted to evaluate stand density-specific and generalized allometric equations, and biomass expansion factors (BEFs) for two stand densities (high density of 47-year-old:
; low density of 49-year-old:
) of Cryptomeria japonica plantations in Namhae-gun, located in the southern Korea. Biomass in each tree component, i.e. foliage, branch, and stem, was quantified by destructive tree harvesting. Allometric regression equations of each tree component were significant (P<0.05) with diameter at breast height (DBH) accounting for 80-96% of the variation except for branch biomass in high density or foliage and cone biomass in low density. Generalized allometric equations can be used to estimate the biomass of C. japonica plantations because the slopes of allometric equations were not significantly different by the stand density. The biomass expansion factors (BEFs) were significantly lower in the high stand density (1.33) than in the low stand density (1.50). The results indicate that BEFs were affected by different stand density, while allometric equations were little related to the stand density.

Journal of Korean Forest Society, volume 103, issue 2, 2014, Pages 182~188
DOI : 10.14578/jkfs.2014.103.2.182
Genetic diversity and genetic differentiation in six natural populations of Abies holophylla Max were investigated using ISSR marker system. From 6 ISSR primers, the average percentage of polymorphic loci was 85.6%, and the average expected heterozygosity (
) was 0.288. From the result of AMOVA, 94.4% of total genetic variation came from the differences among individuals within populations, and 5.6% was caused by those of among-populations. On the basis of Bayesian inference, genetic differentiation (
) and inbreeding coefficient for all populations were 0.045, 0.038, and 0.509, respectively. The correlation between genetic distance and geographical distance was highly significant at the Mental`s test (r

DOI : 10.14578/jkfs.2014.103.2.189
Basic leucine zipper (bZIP) protein is a regulatory transcription factor that plays crucial roles in growth, development and stress response of plant. In this study, we isolated a PagbZIP1 gene that belonged to Group SE3 of bZIP from Populus alba
P. glandulosa, and investigated its expressional characteristics. The PagbZIP1 is 844 base pairs long and encodes a putative 144-amino-acid protein with an expected molecular mass of 16.6 kDa. The PagbZIP1 has two conserved domains including the basic and leucine zipper portions. Southern blot analysis revealed that two copies of the gene are presented in the poplar genome. PagbZIP1 was specifically expressed in the root and suspension cells. Moreover, the expression of PagbZIP1 was induced by drought, salt, cold and ABA. Therefore, our results indicated that PagbZIP1 might be expressed in response to abiotic stress through the ABA-mediated signaling pathway in poplar.

DOI : 10.14578/jkfs.2014.103.2.196
In order to select superior trees based on fruit characteristics and provide basic informations necessary for their improvement, total 107 individual trees of Sorbus alnifolia (Sieb. et Zucc.) K. Koch were selected from 11 wild populations in South Korea. After collecting normal fruit branch, we investigated morphological characteristics of fruit and then considered its relationship among the 11 populations by multivariate analysis method. Results from principal compound analysis showed that it represented 85.8% accumulated explanation from five principal compounds. According to cluster analysis based on fruit characteristics, the natural S. alnifolia populations were classified into four groups and Mt. Mani population was different from other populations. Selection effect with outstanding candidate trees including superior 5 individual trees (Gwangyo 1, Gwangyo 2, Deogyu 7, Mani 29, Mani 30) was estimated at 122.8%, 115.5% and 182.7% in fruit width, length and yield per fruit bunch, respectively. The object of this results will give us invaluable information about breeding by selection of S. alnifolia in south Korea.

Journal of Korean Forest Society, volume 103, issue 2, 2014, Pages 203~210
DOI : 10.14578/jkfs.2014.103.2.203
The purpose of this study was to investigate the effect of experimental warming using infrared lamps on seed germination and seedling survival rate of Pinus densiflora and Abies holophylla. The air temperature of warmed plots had been automatically maintained 3 higher than control plots. The percent germinations (%) of the two coniferous species were higher in warmed plots than in control plots, however a significant difference appeared only in A. holophylla. In addition, P. densiflora and A. holophylla showed the shorter mean germination time (days), higher germination rate (
) and germination energy (%) in warmed plots than in control plots. A. holophylla showed a higher seedling mortality rate in the warmed plots than in control plots because of increased air and soil temperatures and decreased soil moisture. However, seedling survival rate of P. densiflora showed no significant difference by experimental warming. In the future, changed air and soil temperatures and soil moisture due to global warming will induce a variety of changes in seed germination and survival rate of tree species in nursery culture. Therefore, it is necessary to establish adaptation strategies that improve techniques in nursery culture against global warming.

Journal of Korean Forest Society, volume 103, issue 2, 2014, Pages 211~217
DOI : 10.14578/jkfs.2014.103.2.211
A metabolomic study using GC/MS analysis was conducted to identify key metabolic components regulating the growth of open-pollinated Pinus koraiensis families, which were grown for 29 years at three different locations. Among 110 individual metabolites identified, the contents of 62 metabolites were higher in the superior than in the inferior families (p<0.05), together with 22 metabolites, such as phosphoric acid, alanine, glycine, malic acid, and sucrose, being accumulated 1.5-fold higher in the superior families. In addition, 15 metabolites including alanine, malic acid, sucrose, d-turanose, and succinic acid showed positive correlation with the growth (p<0.01). Furthermore, the metabolites, of which contents were correlated with the growth but not significantly changed at different locations, were acetic acid, succinic acid, butanoic acid, glutamic acid, and inositol. Therefore we suggest that several metabolites selected in this study may be used as metabolic markers for quantitative growth trait in P. koraiensis.

Landslides, one of earth`s natural disasters, increase every year due to heavy rainfall, and cause damage to human life and assets. This study used the SHALSTAB to predict places at risk of landslides, in accordance with the intensity of rainfall. The parameter value of transmissivity was
, the internal friction angle
, and the saturated unit weight
. The slope stability status was classified into four categories, namely: unconditionally stable, stable, unstable and unconditionally unstable. In order to evaluate the applicability of the SHALSTAB, actual landslide areas were checked, with the unstable area under 263 mm rainfall. 85.1% of them were consistent. And so we can identify the distribution of places at risk of landslides, on the basis of the intensity of rainfall by means of SHALSTAB.

This study was carried out to propose the criteria for the prediction of landslide occurrence through analysis the influence of each factor by using the quantification theory. The results obtained from this study are summarized as follows. From a stepwise regression analysis between the landslide area(
) and environmental factors, the factors strongly affecting the landslide sediment(
) were the Parents rock (igneous), cross slope(complex), coniferous forests (forest type) and slope gradient (
). According to the range, it was shown in order of Cross slope (0.2922), Parents rock (0.2691), Forest type (0.2631) and Slope gradient (0.2312). The range of prediction score of landslide occurrence has been distributed between score 0 and score 1.0556, the median value was score 0.5278. The prediction for class I was over 0.7818, for class II was 0.5279 to 0.7917, for class III 0.2694 to 0.5278 and for class IV was below 0.2693. The prediction on landslide occurrence appeared relatively high accuracy rate as 72% for class I and II. Therefore, this score table for landslide will be very useful for judgement of dangerous slope.

Journal of Korean Forest Society, volume 103, issue 2, 2014, Pages 240~247
DOI : 10.14578/jkfs.2014.103.2.240
This study was conducted as a restoration research in a mountain stream of hydrologic cycle system, which is a type of microsites purposely changing vegetation. The status of vegetation in the three experimental sites, water purification site, small dammed pole site, and aquatic plant restoration site, and one control site within the area of the mountain forest stream were investigated in three different periods, namely before sites restoration, year of sites restoration, and year after sites restoration. After one year of restoration, number of vegetation was increased in the small dammed pool and control site respectively. Vegetation coverage ratio of Zizania latifolia was increased at the water purification area. The effects of habitats restoration appeared to be good a year after the restoration of the experimental sites, in terms of families and species composition of the introduced vegetation, and stream flow. Therefore, the results of the study strongly suggest that fairly effective ways to restore and reproduce degrading mountain hydroecological habitats are by way of forming pool sites and small dams in intermittent mountain streams and re-vegetating with selected plants.

Journal of Korean Forest Society, volume 103, issue 2, 2014, Pages 248~257
DOI : 10.14578/jkfs.2014.103.2.248
The objectives of this study were to identify the root plate dimension of wind-uprooted trees and to analyze the relationship among wind direction, aboveground and belowground properties of the trees. The root plates of 77 Japanese larches (Larix kaempferi) and 24 Korean pines (Pinus koraiensis), which were uprooted by a typhoon in 2012, in the Taehwa Experimental Forest of Seoul National University, Korea, were investigated. The results showed the root plate shape could be assumed to be an oval or a circle in above view, and half an ellipse in side view, respectively. Also, the number and surface area of individual roots in root plates were greater in uprooting direction than in non-uprooting direction. The results of correlation analyses between aboveground and belowground properties indicated DBH had more significant correlation with belowground properties than tree height. Finally, simple linear relationships were derived for significantly correlated tree aboveground and belowground properties.

DOI : 10.14578/jkfs.2014.103.2.258
The purpose of this study is to provide basic data for forest roads management by using AHP methodology to group the grade of disaster risk. In addition to this, a field study was performed at 114 targeted points on forest roads where there are high risks of disaster occurrence. The results of the field survey and the analysis of AHP were compared to provide the degree of disaster risks. It shows that the drainage facilities occupied the highest weighted value. Meanwhile, based on AHP analysis data, evaluation chart was created by providing evaluation criteria and evaluation score to each evaluation items. As a result of applying the evaluation chart to the field survey data, the highest score was 78.8 and the lowest score was 42.7 with the mean score of 61.8. Finally, through the experts` consultation based on calculated scores, this study proposed four different groups of disaster risk on forest roads.

Journal of Korean Forest Society, volume 103, issue 2, 2014, Pages 264~269
DOI : 10.14578/jkfs.2014.103.2.264
The aim of this study was to determine the current distribution area of Robinia pseudoacacia habitat and to estimate its stand yield as well as its carbon stocks. In order to do so, the area of R. pseudoacacia distribution is obtained based on the large-scaled forest type map (1:5,000). Also, Weibull diameter distribution model is used to predict the yield of R. pseudoacacia stands. In addition, carbon emission factor is applied to calculate carbon stocks and removals. To obtain the stand yield of R. pseudoacacia, we developed estimation equation considering growth factors of the stand, e.g. mean diameter, the basal area, maximum and minimun diameter and etc. and tested it to ensure accuracy. Consequently, estimation equation derived from all growth factors have shown significance that could also be used for analysis. Site index was also established to determine the productivity of the forestland that later turned out to be ranging from 16 to 22. Based on these results, stand yield tables were drawn up. R. pseudoacacia is widely distributed in inland areas of Gyeongsang, Chungcheong and Gyeonggi provinces which covers total area of 26,770 ha. And when it is converted into carbon stocks, it amounts to 2,517,598tC with annual carbon uptake of 3.76tC/ha which is comparable to Querqus species that is known to storer large amounts of carbon. Therefore, R. pseudoacacia is also expected to serve as a viable carbon pool that would contribute to the mitigation of climate change. Furthermore, stand yield tables, an outcome of this survey would assist not only in proper management but also in sustainable management policy of R. pseudoacacia.

DOI : 10.14578/jkfs.2014.103.2.270
This research analyzed job satisfaction for improvement in job satisfaction of forest interpreters and effective management. Interpreters felt satisfied with their job with a mean satisfaction score 3.41 out of 5 but unsatisfied with pay and job benefits. Job satisfaction showed significant differences in interpreting field, agencies and working period. Results from factor analysis, job satisfaction classified into four factors; team atmosphere, level of compensation, job conflict and working environment. And interpreters more satisfied in team atmosphere and working condition than level of compensation and job conflict. Also this study showed related variables to job satisfaction. Team atmosphere was related with working period and agency, the level of compensation was also related with agency and the working environment is in relation to agency and interpreting field.

Forestry management problems in South Korea have been caused by small and scattered forest lands, aging forest owners, and the increase of absentee forest owners. To solve these problems, it is a time to consider the introduction of forest land bank system for the expansion of forestry management scale, the effective management of neglected forest lands, and the stable livelihood support for aged forest owners. Therefore, this research implemented the questionnaire survey of necessity, expectation, willingness to use, and introduction plans for the forest land bank system in order to examine the feasibility and demand of the system focused on forest owners, non-forest owners, and people who return to the farm. The questionnaire survey was conducted for 262 of resident forest owners, 152 of absentee forest owners, 427 of non-forest owners, and 101 of people who return to the farm. 77.5% of forest owners and 63.8% of non-forest owners agreed with the necessity of the introduction for the forest land bank system. Both forest owners and non-forest owners would prefer to use forest land reverse mortgage and leasing among projects of the forest land bank. In addition, 75% of people who return to the farm also expected that forest land bank would be helpful to their rural and mountain life, and they would have higher preference to participate in leasing and buying forest lands than other projects. Based on the outputs of the feasibility and demand survey in this research, this study can play a key role in determining basic direction, major functions, types and range of projects as well as providing information for establishing policies of the forest land bank system.

DOI : 10.14578/jkfs.2014.103.2.287
This paper aims to analyze the satisfaction level of people for the different types of tree burial sites, in order to suggest directions for the policy to revitalize tree burials. For the purpose of this study, the tree burial sites were classified into four types, and we conducted a questionnaire, targeting 414 visitors to the different case sites. Through the comparative analysis among the case sites, this study found that people prefer the public tree burial sites to the private ones, and most people liked the type of tree burials best created in a natural forest among the public sites. Based on these results, this study suggested that the policy should be focused on the revitalization of public tree burial sites created especially in natural forests in order to satisfy the preference of people. Through the analysis of the questions regarding the general citizens` awareness of tree burials, this study found the improvement measures are required for convenience facilities, low satisfaction for usage charge, low credibility for private tree burial sites, and strong demands to create stable growth environment for memorial trees. On the other hand, this study confound the bright prospect for the spread of tree burials because people who have used tree burial sites were highly willingness to recommend tree burial sites to others and they wanted to do a tree burial for their own funerals.

Japan and Korea have developed forest therapy policies, but their policies differ in several respects. First, Forest therapy projects are managed by local governments and residents in Japan, while they are operated by Korea Forest Service. Second, Japan adopts the certification system of forest therapy areas, emphasizes medical and scientific evidences, maintains the quality of forest therapy by inducing competitive participation of local governments and residents, and cultivates forest therapists through Forest Therapy Society. In contrast, Korea has adopted the licence system, improved institutional framework, and cultivated therapists, but it is at early stage. Third, Japanese forest therapy policy aims at regional development of the mountain villages, overlapping with other local policies. However, in Korea, the primary policy goal is to expand forest services and thereby having its own policy framework and being promoted strongly.

Wild boar have increased in recent years in Korea where damage to agricultural crops is considered as a social issue. The ecological studies on wild boar are essential for the effective management in the future. During May and December 2012, We collected 79 wild boar stomach samples from culling program implementation to reduce agricultural damage in Geochang County and analyzed stomach contents to figure out wild boar diet habit and which crop was preferred. There was seasonal variation in the diet. Plant foods represented up to 93.5% of the diet and were consumed more frequently than animal foods. Invertebrates occurred with high frequency but were underestimated in dry weight because they are rapidly digested. Agricultural crops consumed comprised mainly chestnuts(33%), rice(33%), and apples(24%). Agricultural crops are also a potentially important food resources for wild boar. The frequency of occurrence of earthworms was 50% of diet. Earthworm consumption generally increased in summer, and then decreased in winter. Our results show that wild boar can be considered an omnivore whose diet consists of plant and animal foods. To reduce wild boar agricultural damages, We have to focus on the prevention effort to rice paddy adjacent to chestnut forest and to apple orchard.
