To investigate the changing patterns of sub-alpine forest vegetation due to climate change requires accumulation of contiguous reference data and continuous monitoring. Furthermore, it is crucial to monitor short-term ecological change of lower level vegetation to understand the trend of long-term vegetation change. Therefore, this study carried out a vegetation survey and tree diameter measurement in 36 plots of Mt. Jiri inhabited by Abies koreana species from 2015 to 2017 to examine the short-term dynamics of Abies koreana seedling and the change of vegetation distribution according to altitude. We analyzed the importance value and MIV (mean importance value) of major species by each stratum as well as the importance value and species diversity index of major species and the change of seedling population by altitude. The results showed that Abies koreana had the highest importance value on tree layer, Rhododendron schlippenbachii on shrub layer and Tripterygium regelii on herb layer. MIV was high in the order of Abies koreana, Rhododendron schlippenbachii and Acer pseudosieboldianum. Regarding the species composition and species diversity index (H') along the altitudinal gradient, Sasa borealis showed high MI and low H' in the elevation less than 1,500 m, and IV of Tripterygium regelii and H' of herb layer were high in the elevation of 1,700 - 1,800 m. Abies koreana seedling decreased by 22.4% from 1,250 n/ha in 2015 to 970 n/ha in 2017 (p <0.05) throughout the investigated area. The decline rate along seedling and sapling height were 22.9% in less than 10 cm, 3.4% in 10-30 cm, 8.9% in 30-50 cm, 39.3% in 50-100 cm, and 55.1% more than 100 cm. Few of A. koreana seedlings appeared due to the dominance of Sasa borealis in the elevation of 1,500 m or less and due to the dominance and high species diversity of Tripterygium regelii in the elevation of 1,700-1,800 m. On the other hand, many of A. koreana seedlings appeared in the elevation of 1,600-1,700 m due to no distribution of S. borealis and T. regelii species in that altitude range. Therefore, we concluded that those seedlings and saplings of A. koreana could be more stable in the altitude of 1,600-1,700 m.

The range of D. spathulata identified in this survey was between N 35° 24' 58" ~ N 35° 26' 35", E 129° 05' 43" ~ E 129° 07' 04". It is located at an altitude of 98~592 m. The soil pH was strongly acidic in the range of 4.2~4.9, with a canopy openness of 18.56% and a chlorophyll index of 36.74 ± 2.80. As a result of the TWINSPAN analysis, 20 plots of 100 m² each were divided in 4 communities: Pinus densiflora community, Quercus monglica-Diabelia spathulata community, Quercus serrata-Diabelia spathulata community and Carpinus tschonoskii subassociation. The result of species diversity was 0.7615, and evenness and dominance were found to be 0.6077 and 0.3923, respectively. The height of D. spathulata is up to 3.4 m, and the average height is 1.1 m, with most of the species distributed as shrubbery and herbaceous. The average population density of the 20 plots was 1.635 individuals/m², the height range of flowering was 1.0 ~ 1.8 (aver. 1.39 m) and the rate of flowering was 27.37%. It's propagation pattern was mainly formed by extending the rhizome to the side, creating a colony of ground stems.

In order to clarify the species composition, distribution and habitat of the Korean wild Pyrus ussuriensis and P. pyrifolia communities, that are so expected as a useful resource plant, an investigation was carried out according to phytosociological method on Mts. Hambaek, Ilwol, Sobaek, Juwang and Gaya in Korea. In the present study, we made an attempt to elucidate the autecological characteristics of the wild Pyrus species by synecological approach. As a result, the forests including the Pyrus species were divided into the two associations and two communities, considering the existing vegetation units for the forest; Syneilesio-Quercetum serratae, Corylo-Quercetum mongozicae, Ainsziaea acerifolia- Quercus mongolica community and Fraxinus rhynchophylla-Pyrus ussuriensis community. Among the units, the Syneilesio-Quercetum serratae and the Corylo-Quercetum mongolicae belong to southern type and middile-northern type, respectively, in their distributional type. It is inferred that the wild Pyrus species are distributed preferably in the deciduous forest zone in Korea, compared to the other forest zones. In particular the Pyrus species are present alone or dominantly in only both the tree layer or subtree layer of the forests, reflecting their shade intolerance ecophysiologically. Thus they usually were distributed in SE or SW of slope aspect. Generally the canopy of the forests including the Pyrus species was so open. Species diversity of the vegetation units was highest in the Syneizesio-Quercetum serratae and lowest in the Ainsliaea acerifolia-Quercus mongolica community. The Corylo-Quercetum mongolicae and the Pyrus ussuriensis-Fraxinus rhynchophylla community are medium between the two.

The purpose of this study is to offer raw data regarding landscape plantings of traditional cultural heritages by surveying and analysing the actual flora and landscape planting species distributed in Donggung Palace and Wolji Pond in Gyeongju, Korea. The results are as follows. The flora were summarized as 149 taxa including 65 families, 117 genera, 134 species, 1 subspecies, 10 varieties and 4 forms. The naturalized plants were of 18 taxa including Rumex crispus, Trifolium repens, Ailanthus altissima, Veronica persica, Senecio vulgaris, Festuca myuros and the like. Invasive species included Rumex acetosella. As a result of the analysis of chronological changes in landscape planting species, 23 taxa were planted in 1979, whereas 48 taxa were planted in 2014. Therefore, the number of these species increased by 25 taxa. The landscape planting species were of 48 taxa including 6 taxa of evergreen trees, 2 taxa of evergreen shrubs, 27 taxa of deciduous trees, 12 taxa of deciduous shrubs and 1 taxa of other. In present conditions by sections, Section A was 25 taxa, 15 taxa of Section B, 13 taxa of Section C and 29 taxa of Section D. The species planted in common were 4 taxa including Pinus densiflora, Acer palmatum, Euonymus alatus and Rhododendron yedoense for. poukhanense. The problems in the present conditions of landscape planting were volunteer species, the occurrence of scrub and vines and the spread of invasive alien plants. To restore and improve the planting landscape and facilitate tree growth, scrub, volunteer species and invasive alien plants must be removed.

To investigate the vegetation structure of mountain ridge from Bammeorijae to Woongseokbong, 25 plots($400m^2$) selected by random sampling method were surveyed. Three groups of Quercus mongolica - Pinus densiflora community, Q. dentata community and Q. mongolica - Q. dentata community were classified by cluster analysis. Q. dentata, Q. variabilis, Pinus densiflora, Acer pseudosieboldianum and Q. mongolica were found as mostly dominant woody plant species in the Woongseok-bong area. In the future, the importance percentage of Pinus densiflora might be eventually decreased, but those of Q. mongolica, Q. variabilis and Q. dendata might be gradually increased. There were strong positive correlations between Pinus densiflora, Zanthoxylum piperium and Lindera obtusiloba; Q. mongolica and Rhododendron mucronulatum; Styrax obassia and R. schlippenbachii; Fraxinus sieboldiana, Zanthoxylum piperium and Styrax obassia; Acer pseudosieboldianum and Fraxinus sieboldiana; Cornus controversa and Corylopsis coreana were relatively weak negative correlations between Q. dentata and Q. mongolica; Lindera erythrocarpa, Q. mongolica and Q. variabilis; Q. mongolica, Larix leptolepis and Q. variabilis; Symplocos chinensis for. pilosa and Rhododendron mucronulatum. Species diversity index(H') of investigated groups was ranged from 0.09832 to 1.1102.

We investigated the plant phenology on the threatened species for climate change in the summit area of Mt. Deogyusan which is a representative sub-alpine zone in Korea. We had performed the monitoring survey of plant phenology on 38 species including 20 trees and 18 herbs from May 2009 to November 2010. The investigated phenological charateristics were five dates for leafing, flowering, floral abscission, autumn leaf colors and leaf abscission on each plant species in sub-alpine region. The climate data were measured from November 2009 to December 2010. The range of temperature was from 30.4 to -$20.3^{\circ}C$ at Hyangjeokbong to Jungbong region, and the relative humidity was 100% to 3.4%. The leafing dates in 2010 were similar to 2009 or were 6-20 days delayed in most of the investigated species except Veratrum oxysepalum and Sanguisorba hakusanensis which showed 8 days earlier leafing dates in 2010. The biggest difference among phenological characters was found in flowering dates. The flowering dates of early Spring blooming species such as Heloniopsis koreana, Rhododendron yedoense for. poukhanense and Viola orientalis showed 13-20 days earlier in 2010, and the several summer flowering species as Viburnum opulus var. calvescens, Smilacina japonica and Bupleurum longeradiatum showed 6-10 days delay in 2010. The dates for floral abscission and autumn leaf colors in 2010 were delayed about 10-18 days, and leaf abscission dates were similar to 2009. The effects of climate change on the phenology for the threatened species in sub-alpine zones of Korea are occuring especially on flowering, floral abscission and autumn leaf colors.
