희귀식물은 야생화 애호가의 선망의 대상이다. 희귀식물을 찾기 위한 애로호가들의 활동은 참으로 열성적이다. 그런데 희귀동식물은 단순히 희귀성을 쫓는 사람들에게만 중요한 존재가 아니다. 희귀식물은 미래의 자원으로서 활용가치가 뛰어나기 때문에 국가 차원의 보호노력이 요구된다. 특히 우리만이 가지고 있는 자원이라면 그 상대적 활용가치는 무궁무진하다. 세계 여러 나라가 생물다양성협약에 주목하는 이유이기도 하다.

This study was conducted to examine the change of flora and plant species diversity between 2005 and 2010 in Yangjaecheon (stream) which was divided among three different types of vegetation management method; ecological vegetation management (weeding vines and invasive plants; EVM), plant cultivation (PC) and uncared for vegetation (UC). There were total 478 taxa, composed by 429 spontaneous taxa and 49 cultivated taxa in 2005 and total 424 taxa composed by 318 spontaneous taxa and 106 cultivated taxa in 2010. In spontaneous plants, 201 taxa were distributed over total area, 197 taxa were distributed in only EVM area, 10 taxa in only PC area and 59 taxa in only UC area. Also, the most dominant family (Asteraceae${\rightarrow}$Poaceae) and number of rare taxa (reduced) and wide distributed taxa (increased) was changed from 2005 to 2010. The rate of perennial taxa was found to be increased in only EVM area. In conclusion, EVM is thought to be a more efficient method for plant species diversity of restored stream.

국립수목원은 열대유용식물의 BT산업 원천소재 확보 제공을 목적으로 열대자원연구센터를 건립하여, 열대 및 아열대 전시원을 관리하고 있다. 온실의 특성상 일반 재배환경과는 다르게 여러 종류의 식물의 혼합 식재되어 있는 특성이 있어서 농업환경과 달리 해충의 급격한 돌발에 의한 온실 전체적인 피해의 위험성이 적은 반면에 안정된 환경으로 인해서 해충의 취약한 몇몇 수목의 경우 해충이 급격히 늘어날 수 있다. 본 실험은 여러 종류의 식물이 혼재되어 있는 수목 온실 내에서 생물적 방제를 이용하여 주요 해충류인 진딧물류 및 가루 깍지벌레, 잎응애류 방제 가능성을 타진하고자 진행되었다. 진딧물이 집중적으로 발견된 열대식물 5종(Acalypha hispida, Justicia gendarussa, Hamelia patens, Ficus petersii, Hibiscus rosa-sinensis)을 중심으로 천적 방사 및 Banker plant 설치를 진행했다. 최초 조사일인 2015년 3월 10일, Tropical 1에 진딧물류의 발생이 많이 확인되어 포식성 천적인 미끌애꽃노린재를 투입했다. Tropical 2는 2015년 3월 17일 기생성 천적인 콜레마니진디벌과 선발된 Banker plant를 적용하여 방제 되었다. 철모깍지벌레가 발견된 열대식물 3종(Sanchezia parvibracteata, Brillantaisia lamium, Pseuderanthemum atropurpureum)을 중심으로 적용 천적으로 어리줄풀잠자리, 애홍점박이 무당벌레와 깍지무당벌레를 선별했다. 천적을 대상으로 철모깍지벌레에 대한 포식능력을 조사했으며 애홍점박이 무당벌레가 어리줄풀잠자리 보다 2.8배, 깍지무당벌레보다 2.9배 포식능력이 뛰어남을 확인했다. 잎응애류가 발견된 열대식물 2종(Acalypha wilkesiana, Erythrina caffra)은 천적으로 사막이리응애와 칠레이리응애를 적용하였다. 괭이밥응애 성충과 알의 포식력을 검증한 결과 사막이리응애가 괭이밥응애를 먹이로 증식이 가능한 것으로 확인되었다. 괭이밥, 괭이밥응애, 사막이리응애를 효과적으로 조합한 응애류 방제를 위한 새로운 Banker plant의 개발 가능성을 확인할 수 있었다. 연구는 열대온실의 열대식물 관리에 대한 생물학적 방제의 지속적인 모니터링을 통해 종합적 방제의 관리 자료로 이용되어 새로이 온실을 조성하는 경우 식재기반조성에 실질적인 도움을 줄 수 있으며, 추후 열대식물의 자원 식물로서의 활용성을 높일 수 있다.

For modern people who lack the time, the plants became more interested as they gave emotional stability and proved the purifying function of plants from harmful substances such as fine dust. In this study, we established a standard vegetation cultivation system that can easily grow indoors without any special knowledge, based on criteria such as temperature, soil humidity, and illumination. And we implemented a system that provides simple information needed for plant management by using Bluetooth function and provides contents that can get know-how necessary for plant management.

This study was carried out to propose the baseline data for in situ conservation by analyzing environmental and growth characteristics in Pedicularis hallaisanenesis habitats. P. hallaisanensis habitats, according to investigations, were located on the slope of southwest at an elevation of 1,400 m in Mt. Gayasan and on the slope of southeast at an elevation of 1,500 m in Mt. Hallasan. Pedicularishallaisanensis habitats. Also, habitats were found at the grassland with no upper vegetation. In the study sites, soil pH and soil organic matter were 4.9-6.5 and 4.4-8.1%, respectively. A total of 55 vascular plants taxa were identified in ten quadrats in two habitats, of which 25 were inhabited in Mt. Gayasan and 37 in Mt. Hallasan. Current status of P. hallaisanensis habitats were very vulnerable with the pressure of the vegetation constantly threatening the species' survival. Thus, concrete conservation plans including diverse factors as light intensity, temperature and genetic analysis to protect natural habitats should be set up as soon as possible.

This study presents the flora of nonvascular plants (bryophytes) and vascular plants within the Wangpicheon Ecosystem and Landscape Conservation Area in Korea. The time of the survey was divided into four seasons. The fieldwork was conducted for a total of 18 days from November of 2016 to October of 2017. The land plants in the Wangpicheon conservation area were identified as 758 taxa with 164 families, 455 genera, 698 species, 10 subspecies, 47 varieties and 3 forms. Among them, bryophytes amounted to 122 taxa and vascular plants numbered 636 taxa. Native plant amounted to 693 taxa. In total, there are 113 floristic target species in Korea, including one level V taxon, in this case Swertia wilfordii; six level IV taxa; 31 level III taxa; 38 level II taxa; and 37 level I taxa. There are nine endemic plants, including Sillaphyton (=Peucedanum) podagraria, which is the endemic genus; two rare plants; fifteen northern plants; and one southern plant as target plants adaptable to climate change. Also, there are forty-six naturalized plants and five ecosystem-disturbance organisms. The results of this study suggest several species that should be preserved and can serve as basic information with which to establish conservation and management plans for the Wangpicheon conservation area.

This study is to examine the section-based stream management with environmental characteristics and user monitoring. In Jeonjucheon, upstream section located near to Jeonju Hanok village has very good water quality and natural stream landscape. In case of mid/down streams, water quality is good and heavy concentration of facility leads to high use rates of these sections. The questionnaire consists of 5 parts: user characteristics, use behavior, citizen participation, importance rank, and Importance-Satisfaction(IS). 383 out of 454 responses with listwise deletion are used for demographic analysis and IS Analysis. In terms of citizen participation through 'ecological experience activity' and 'stream stewardship activity', 'occasional participation' shows the average of 78% in all three sections. For importance rank, the results arranged in order of priority show 'water quality' > 'green corridor' > 'trail' in up/down streams and 'water quality' > 'vegetation management' > 'trail' in midstream. Therefore, 'water quality' appears to be the most important variable among 13 variables. At last, the results of ISA indicate that all 10 variables need to be improved as satisfaction is lower than importance. In addition, 'plant management' variable falls into 'concentrate here' quadrant where importance is high and satisfaction is low.

본 발표는 국가 멸종위기종의 보전을 위해 환경부에서 지정하는 서식지외보전기관의 그간 성과와 향후 운영방향에 대한 것이다. 서식지외보전기관은 서식지내에서 보전이 어려운 야생동 식물을 서식지외에서 체계적으로 증식 보전할 수 있도록 연구경험, 인력, 시설 등이 갖추어진 연구기관을 심사해 환경부에서 지정하고 지정대상기관이 운영하는 제도이다. 국립낙동강생물자원관은 최근 3년간 멸종위기식물 4종(섬개현삼, 분홍장구채, 대청부채, 큰바늘꽃)과 일반식물 1종(고란초)의 현장관리 및 증식연구 등을 통해 보전기반을 마련하여 현장평가를 거쳐 환경부로부터 2018년 1월 30일 지정서를 교부받았다. 이에 지금까지의 연구결과와 향후 연구방향에 대해 발표하여 관련분야 전문가의 고견을 받아 서식지외보전기관의 관리와 운영에 반영하고자 한다.

Urban streams are degrading functional role due to development and pollution. This study chose the representative stream of Do-rim and identified flora and fauna. The ecological survey aimed at identifying indicator of urban streams for measuring urban healthiness and we discussed the possibility of wetland conservation area. From the beginning of Dorim stream to An-yang mixture we were successfully identified 113 species of plants, 9 of mammals, 23 of birds, 4 of amphibians, 2 of reptiles and 2 of fish species. Terrestrial insects were 71 species. The wetland vegetation is quite various and we suggested 4 different vegetation zones (aquatic vegetation zone, emergent zone, riparian-meadow zone, riparian-woodland zone) depending on distance from the flowing water stream and vegetation characteristics for urban stream management.

This study was to describe the ecological survey of wetland plants from Sinbul Mt. and suggest the ways of the sustainable ecological management and wise use. We found 167 plant species. Molinia japonica HACK was the most dominant species and Asarum maculatum NAKAI, Drosera rotundifolia L. and Utricularia racemosa WALL were considered as the most important species. Thus, it was concluded that this area need strong conservation due to the necessity for species diversity. Such several management schemes as the designation for national wetland conservation area, continuous monitoring, cautious surveillance and wise management were suggested to implement successful conservation.
