This study aimed to identify the growth environment of Cudrania tricuspidata by analyzing the site environment, soil characteristics, and vegetation structure of the species habitats and to provide basic data for identifying suitable cultivation sites for mass production. The study was conducted on 17 sites in five cities/counties of Gyeongnam and Jeonnam province. It was found that C. tricuspidata habitats were mainly distributed on gentle slopes in the southeast and southwest, with an average altitude of approximately 290 m. The soil of the C. tricuspidata habitats was sandy loam with a high proportion of sand, averaging 73.9%, 4.6%, and 21.5% sand, silt, and clay, respectively. The soil had a pH value of 5.41 (5.20-5.79), organic matter content of 8.2% (3.6-12.6%), total nitrogen content of 0.36% (0.19-0.54%), available phosphorus content of 3.50 ppm (0.95-7.61 ppm), and cation exchange capacity of 15.9 cmol⁺/kg (10.0-20.7 cmol⁺/kg) on average. The vegetation structure analysis showed that C. tricuspidata appeared in the tree layers of regions A (Jinju) and E (Yeosu), but the importance of C. tricuspidata was found to be high in the subtree and shrub layers in all regions. The ecological niche breadth was widest (0.874) in region B (Hadong) and narrowest (0.480) in region E (Yeosu).

This study was conducted to provide basic data for the establishment school forests in order to utilize school forests as a place for environmental education through analyzing the planting status in elementary schools located in Changwon-city. School forests including meditation forest were the largest in Yongho elementary school (below e.s.) in meditation forest school and Dogye (e.s) in normal school. Jehwang (e.s.) and Sangnam (e.s.) showed the most abundant green area given for the management per member. The number of planting species and individuals in school forests differed greatly by elementary schools. There was also a difference in the number of planted species for establishment of meditation forest. There were no significant difference the concordance rate between the plants planted in the school forest and the plants mentioned in the textbook between meditation forest schools and normal schools. Index of ecological health averaged 3.2 for meditation forest schools and 2.4 for normal schools, which is the result of increase in green area and green rate due to the establishment of the meditation forest.

The ecological characteristics of Cymbidium macrorrhizum habitats in Nozasan (Mt.) of Geoje-city were investigated to provide basic data for conservation and restoration. Field investigations including site characteristics, soil environment, and vegetation structure were conducted in 24 sites from Jun. to Aug. 2020. The altitude of C. macrorrhizum habitats ranged from 84 m to 137 m with slopes of 2∼12o. The rock exposure rate was on average 16.2%, and it was found to be in the range of 9% to 22% for each site. Effective soil depth and litter depth were on average 19.3 cm and 10.9 cm, respectively. Rock exposure rate, effective soil depth, and litter depth were relatively high in sites 1 and 6, where the number of C. macrorrhizum was large. In soil environments, it was found out that average soil moisture content was 25.9% (24.2 to 27.9%); 5.76 (5.52 to 5.99) for soil pH; 6.86% (5.25 to 8.48%) for soil organic matter; 0.34% (0.28 to 0.42%) for total N content; 5.52 ppm (3.0 to 10.8 ppm) for available phosphorous, and 16.9 cmol+/kg (15.2to18.9cmol+/kg) for CEC. Exchangeable cations were decreased in order of Mg2+>K+>Ca2+>Na+, which was different from general results decreasing in order of Ca2+>Mg2+>K+>Na+ in forest soils. The dominant species of site 1 were Pinus thunbergii at the tree layer, Styrax japonica, Eurya japonica and Sorbus alnifolia at the subtree layer, Viburnum erosum at the shrub layer, and Oplismenus undulatifolius at the herb layer. Site 2 were dominated by P. thunbergii at the tree layer, E. japonica at the subtree and shrub layer, and O. undulatifolius at the herb layer. Site 3 was dominated by P. thunbergii at the tree layer, S. japonica at the sub-tree layer, Callicarpa japonica at the shrub layer, and O. undulatifolius at the herb layer. Sites 4, 5 and 6 were dominated by P. thunbergii at the tree layer, S. japonicus and L. erythrocarpa at the sub-tree layer, with Callicarpa japonica, Lindera erythrocarpa and Zanthoxylum piperitum at the shrub layer, and O. undulatifolius at the herb layer, respectively. Species diversity index ranged 0.520 (site 5)∼0.980(site 1) at the tree layer, 0.718 (site 3)∼1.133 (site 6) at the sub-tree layer and 0.919 (site 5)∼1.201 (site 6) at the shrub layer. Evenness and dominance were on average 0.730 and 0.270 at the tree layer, 0.722 and 0.278 at the sub-tree layer, and 0.847 and 0.153 at the shrub layer, which illustrated that there was no significant difference among study sites. In Pearson product-moment correlation, C. macrorrhizum had positive association with Carex polyschoena, Chloranthus fortunei and Paederia scandens but negative association with Discorea batatas. C.macrorrhizum had negative association with Dryopteris bissetiana, Viola collina, Carex lanceolata, and Syneilesis palmata in the Spearman Rank Correlation. It is expected that this study, which identified the ecological characteristics of C. macrorrhizum habitats, can be used as basic information for the conservation and restoration of C. macrorrhizum.

The purpose of this study was to provide basic data for the creation of school gardens in order to utilize them as a place for environmental education by comparing and analyzing the planting status in elementary schools located in Geoje-city, Gyeongnam. The study classified distinctly the schools with meditation forests and normal schools while analyzing the current state of school gardens, planting statuses of school gardens, planting statuses of school trees and school flowers, the concordance of plants in school gardens and elementary school textbooks, and the ecological health of school gardens. Although there are differences among schools, school garden areas, green area ratios, and green areas per person of schools with meditation forests are higher than in normal schools. Plants planted in school gardens consisted of 66-70 species in schools with meditation forests, and there were more plant species in these school gardens than the 32-48 species in normal schools. The amount of plantings of species such as Rhododendron indicum, R. yedoense for. poukhanense and Nandina domestica, which are planted for fences and landscapes, are high. There was no significant difference between plants planted in school gardens and plants mentioned in elementary school textbooks, about 40% for schools with meditation forests and 36% for normal schools. School trees were Pinus densiflora, Zelkova serrata, Juniperus chinensis var. chinensis, Ginkgo biloba and Celtis sinensis, and school flowers were Camellia japonica, Forsythia koreana and Magnolia kobus. The green areas of schools with meditation forests was found to be a little wider than that of normal schools, but the green rate and green volume factor were not significantly different between schools with meditation forests and those without. Species diversity is the factor with the greatest difference depending on the type of meditation forest. Connectivity to green belts is absolutely influenced by the suburban environment. If there are insufficient green areas around the schools, it is necessary to expand the school gardens so that they can function as urban forests. The ecological health index of schools with meditation forests is also slightly higher than normal schools.
