  • This study was conducted to investigate the changes understory vegetation composition (shrub and herb layers) in Mt. Gyebang as a northern-temperate deciduous broadleaf forest. Tracheophytes were 146 taxa, consisting 56 families, 93 genera, 124 species, 17 varieties, 3 forma, 2 sub-species and 1 unknown taxa in research subject area. As species area curve analysis, herbaceous layer and shrub species have been decreased over time. As a result of Mantel-test, basal area of upper layer affects to understory vegetation change (p<0.0001). Mean importance value was dominated Lindera obtusiloba (21.585%), Rhododendron schlippenbachii (19.774%) in the shrub layer, identified Sasa borealis (14.082%) and Lindera obtusiloba (7.921%) in the herb layer. According to NMS analysis of shrub layer, Species characterized by strong correlation have been reduced as time goes by. And it reports different species as an increasing in basal area of the upper layer. Herb layer plots of the NMS analysis, Rhododendron schlippenbachii and Rhododendron mucronulatum consistently were affected in shrub layer. In consequence of MRPP-test for changes in vegetation composition, It was analyzed that there are no significant differences for vegetation composition changes on shrub layer in 5-10 years. As a changes of vegetation composition on herb layer were analyzed significantly, composition change of herb layer species was larger than shrub layer species in understory vegetation.

  • In this study, the structure of forest vegetation in Mt. Seondalsan, Bongwha-gun, was analyzed. Vegetation data were collected in 137 quadrat plots using the Z-M phytosociological method from June to October 2018. These data were analyzed using vegetation classification, importance value,and species diversity. Consequently, vegetation was classified as a Quercus mongolica community group that was divided into four communities: Cornus controversa, Phlomis umbrosa, Pinus densiflora, and Q. mongolica communities. The C. controversa community was subdivided into Magnolia sieboldii and Parthenocissus tricuspidata groups; the P. densiflora community was divided into Vaccinium hirtum var. koreanum, Quercus variabilis, and P. densiflora groups. In the C. controversa community, the M. sieboldii group was divided into the Acer mandshuricum and M. sieboldii subgroups, whereas the P. tricuspidata group was divided into the Larix kaempferi, Pinus koraiensis, and P. tricuspidata subgroups. In the P. densiflora community, the V. hirtum var. koreanum group was divided into the Rhododendron micranthum and V. hirtum var. koreanum subgroups. According to importance value analysis, C. controversa, L. kaempferi, P. koraiensis, Q. mongolica, Acer pictum subsp. mono, P. densiflora, and Q. variabilis were mainly indicated to have high value in the tree layer. The species diversity of Mt. Seondalsan was 1.969, which was greater than that of another Forest Genetic Resource Reserve.

  • This study was carried out to classify forest vegetation structure of Mt. Munsu and Mt. Okseok from May to September in 2008 using phytosociological analysis methodology of Z-M school under the purpose of furnishing basic materials for rational and scientific forest management. Total of one hundred five study sites (quadrats) was investigated in the area. Quercus mongolica community group was divided into 5 communities such as Pinus densiflora for. erecta community, Hydrangea serrata for. acuminata community, Salix gracilistyla community, Pinus koraiensis community and Larix kaempferi community. Pinus densiflora for. erecta community was subdivided into Rhododendron micranthum group, Quercus variabilis group and Pinus densiflora for. erecta typical group. Hydrangea serrata for. acuminata community also into Ligularia fischeri group, Deutzia glabrata group (into Juglans mandshurica subgroup, Prunus maackii subgroup and Callicarpa japonica subgroup). Accordingly, the vegetation of the study areas could be described as 1 community group, 5 communities, 5 groups, and 3 subgroups and as 10 units in total. Classified vegetation units were highly correlated with altitude and topography. According the analysis of interspecific association, it was shown as three types which were coincident with differential species and character species on the constancy table.

  • This study was carried out to investigate the flora of Mt. Seoungma (Gyeonggi-do). The vascular plant were collected 13 times (from March to October 2011), and 384 taxa in total were identified, including 94 families, 260 genera, 340 species, 5 subspecies, 37 varieties and 2 forms. Korean endemic plants of this area were nine taxa; Clematis brachyura, Rhododendron mucronulatum, Forsythia koreana, Paulownia coreana, etc. Rare plants (IUCN) by the Korean Forest Service and Korean National Arboretum three taxa were recorded; one Critically Endangered species (CR), Prunus yedoensis, one Vulnerable species (VU), Epimedium koreanum, one Least Concemed species (LC), Phacelurus latifolius. The floristic regional indicator plants found in this area were 15 taxa comprising two taxa of grade V and III, one taxa of grade II, 10 taxa of grade I. Furthermore, therophytes (28.3%), hemicryptophytes (23.0%), hydrophytes (14.3%) showed high proportional ratio in life form spectrum. The naturalized plants were identified as 43 taxa and the percent of naturalized index (NI) was 11.2% of total 384 taxa vascular plants. The vegetation status of investigated area was comparatively well conserved, but the degree of damage was increasing rapidly by the disturbances of human beings. Therefore, a long-term monitoring of vegetation changes and movement grasp must become accomplished.

  • The second year's results of surface fire effects on forest vegetation and soil properties and fire tolerance of various tree species were investigated in Mt. Gwanak, Kyunggi-do, successively after the study of the first year's effect in the same place. Soil moisture contents, organic matters, and most of soil nutrients including exchangeable bases had increased just after fire and went down to become somewhat constant. Available phosphorous at fired area decreased until it became similar to that at unfired area, while pH of subsoil was continuously increasing from just after fire till after 1 year. For Lespedeza and Weigela species, fire tolerance of tree crown was the lowest but reproductive capacity was the highest. And both of them were high for Rhododendron species. More exact classification into Increasers, Decreasers, Invaders and Neutral species was possible in the second year's study. According to comparison of similarities, it was found that the vegetational structure at fired area is slowly restoring to original state as time goes.

  • To investigate the structure of the plant community of Mt. Jookyup area in Kwangnung forest, thirty-seven plots were set up by the clumped sampling method. The classification by TWINSPAN and two kinds of multivariate ordination(RA, DCA) were applied to the study area in order to classify them into several groups based on woody plants and environmental variables. The classification have been successfully overlayed on an ordination of the same data using DCA. The plots can be classified into five groups by TWINSPAN and DCA. The successional trends of tree species by both techniques seem to be expected two ways in the canopy layer. The first is from Pinus densiflora to Carpinus laxiflora and the second is from Pinus densiflora through Quercus mongolica to Carpinus laxiflora. In the understory layer, it was expected that Rhododendron mucronulatum ${\rightarrow}$Lindera obtusiloba, Symplocos chinensis for. pilosa, Viburunum erasum, Styrax obassia${\rightarrow}$Euonymus sachalinensis, Sorbus alnifolia. As the result of the analysis for the relationship between the stand scores of DCA and environmental variables, they had a tendency to increase significantly from the P. densiflora community to Quercus spp. community that was soil pH, total nitrogen, available phosphate and exchangeable potassium, sodium, calcium and magnesium.

  • Seungbong Island is situated about 100km away Inchon Port in the western sea of the Korean Peninsula. Field investigations were conducted for two days each from June 30 through July 1, 1981 and from August 20 through 21, 1981. The results obtained are summarized as follows: Plants growing in this island consist of a total of 193 species (70 families, 151 genera, 170 species, 22 varieties and 1 forma). Pinus thunbergii was confirmed to be the dominant species. The natural degree observed in this island was high, as a whole. The coefficient of ferny plants (Pte-Q) is 0.95, lower than grass. Atractylodes japonica Koidz., Miscanthus sinensis Anders. var. purpurascense Rendle, and Rhododendron mucronulatum Turz. are distributed mainly on the forest bed of Pinus thunbergii. The poor distribution of Chenopodium album var. centrorubrum Makino, Setaria viridis (L.) Beauv., Amaranthus mangostanus Linne is considered attributable to the phenomenon of allellopathy caused by a chemical substance secreted from the leaves of Pinus thunbergii. The component ratio of species in this island is lower than that of other islands due probably to the small area of arable land and grassland. The poor growth of plants in the forest of Pinus thunbergii, the dominant species in this island, seems to be attributed to the low relative light intensity of the forest. Seaside plants consisting of a total of 7 species were distributed mainly in the vicinity of sandy beaches. Naturalized plants comprising a total of 11 species were relatively diversified in the number of species.

  • 블루베리는 진달래 과(Ericaceae) 산앵도나무 속(Vaccinium)의 낙엽성 또는 상록성의 저수고성 또는 반교목성의 과수로, 뉴욕 타임즈가 선정한 세계 10대 장수식품의 하나로 알려져 있다. 우리나라에는 전부터 정금나무, 월귤나무, 모새나무, 산앵도나무 등이 자생하고 있으나, 경제적인 가치가 있는 종은 Vaccinium Cyanococcus로 북미지역에서 육성된 품종들이 들어와 재배되고 있다. 처음 도입된 해는 1965년경으로 지금도 40년 이상 된 나무들이 있고, 상업적으로 재배되기 시작한 것은 2000년이고 공식적인 연구는 2004년 국립원예특작과학원에서 시작되었다. 한국블루베리협회 소식지에 주기적으로 기록되기 시작한 재배면적은, 2007년 112ha, 2008년 217ha, 2009년 313ha, 2010년 534ha이었다가 2011년 1,082ha로 크게 증가하였다. 시도별 재배면적은, 전북이 254ha로 가장 많았고, 충남 186ha, 전남 169ha, 경북 157ha, 충북 118ha, 경기 90ha, 경남 58ha, 강원 47ha, 제주 4ha 순이었다. 특히 2010년부터 2011년까지 한 해 동안 블루베리 재배면적이 크게 증가한 것은 각종 언론매체에서 블루베리 기능성에 대한 홍보와 소비자의 인식 증가와 더불어 새로운 소득 작물로 농가 수요가 확대되었기 때문이다. 이는 블루베리 묘목의 수입이 2009년 327천주에서 2010년 702천주로 크게 증가한 것으로도 알 수 있다. 아울러, 국내로 수입되는 냉동과, 건조과의 수입량도 큰 폭으로 증가하였다. 냉동 블루베리 수입량은 2009년 812톤에서 2010년 4,700톤으로 대폭 증가하였는데, 주요 수입 국가는 미국(3,931톤), 캐나다(557톤), 프랑스(70톤), 태국(18톤), 중국(16톤) 등으로 주스 등 가공품 시장의 수요 증가에 따른 것이다. 건조 블루베리의 수입도 2009년 14톤에서 2010년 54톤으로 증가하였다. 2011년 국내산 블루베리 가격은 생과 1kg에 40,000~50,000원선이었으나 35,000원에 판매하는 농장도 있었고, 냉동과를 62,000원도 판매하는 농장도 있었다. 미국 오레곤 주에서 생산한 블루베리 생과가 금년 7월부터 91톤에서 227톤 정도 수입될 것으로 예상된다. 블루베리의 국내 생산량이 많아지고 수입까지 되면, 농업인들은 더욱 품질 좋은 과실을 생산하도록 노력해야 하고, 잼, 식초, 와인 등의 가공식품 외에 과자, 케익, 머핀 등 베이커리용으로 많이 소비되도록 하며, 지역의 다른 상품들과 연계하여 찾아가고 싶은 관광 개발 등으로 소비 촉진을 위해 고심해야 할 것이다.
