The genus Gueldenstaedtia Fisch. is small genus of Fabaceae that includes four species worldwide. Among these, G. monophylla Fisch and G. verna (Georgi) Boriss. are currently recognized as occurring in Mongolia. Here, we present our findings on G. verna from our recent field surveys in eastern Mongolia in 2020. Gueldenstaedtia monophylla is mostly distributed in the western region, whereas G. verna occurs in eastern Mongolia. The regional conservation status of both species was assessed as near threatened based on criterion B in the country. We provided descriptions, grid distribution maps, taxonomic notes and photographic illustrations of the two species based on our newly collected samples.

한국 동해안 울진군에 위치한 왕돌초 조하대에서 2012년 5월부터 2013년 8월까지 계절별로 해조상 및 군집구조에 관한 연구를 수행하였다. 연구기간 동안 녹조류 12종, 갈조류 29종, 홍조류 81종을 포함한 122종이 채집 및 동정되었으며, 38종의 해조류는 조사지역에서 연중 출현하였다. 정점별 평균 생물량은 봄 472.19-1,198.77 g wet wt. $m^{-2}$, 여름 68.99-631.14 g wet wt. $m^{-2}$, 가을 200.91-401.20 g wet wt. $m^{-2}$, 겨울 53.61-922.32 g wet wt. $m^{-2}$로 나타났다. 생물량에 근거한 왕돌초 해조류의 수직분포는 상부 개도박(Grateloupia lanceolata), 넓은분홍잎(Acrosorium venulosum), 마디잘록이(Lomentaria catenata), 중부 미역(Undaria pinnatifida), 참가시그물바탕말(Dictyopteris pacifica), 괭생이모자반(Sargassum horneri), 감태(Ecklonia cava), 하부 쇠꼬리산말(Desmaeistia viridis), 감태(E. cava), 괭생이모자반(S. horneri) 순으로 확인되었다. 왕돌초에서 출현한 해조류를 6가지 기능형군에 따라 구분한 결과 사상형 34.43%, 성긴분지형 25.41%, 엽상형 24.59%, 다육질형 9.71%, 각상형 5.74%, 유절산호말형 0.82%로 확인되었다. 해조상의 특성을 반영하여 해조군락 특성을 판단할 수 있는 C/P, R/P, (R+C)/P 값은 각각 0.41, 2.79, 3.21로 나타났다. 또한, 왕돌초 조하대 군집 안정도와 환경상태를 다양도지수(H')와 우점도지수(DI)를 기초로 확인한 결과 안정된 것으로 나타났다. 왕돌초 조하대에 서식하는 해조류 종다양성 및 풍부도를 유지하기 위하여 교란이나 부영양화 같은 인간활동으로부터 보호되어야 할 것으로 판단된다.

A recent rise in mean global temperatures suggests a shift in the temporal cycles of natural seasons. The impacts of warming trends can alter the temporal and spatial distribution of flora and fauna. Especially, phenological cycles are very sensitive to the occurrence of alternation of hot and cold seasons. Phenological calendars reflect the natural seasonality. In more detail, phenological cycles affects agriculture and human health (i.e. the amount of fruit production and allergies), as well as tourism industries like flower fairs or festivals. (omitted)

The distribution of Agrimonia gorovoii Rumjantsev in Korea is verified in this study. The species, described as from Primorsky Krai in Russia, was found in Chungcheongnam-do, Gangwon-do, Gyeonggi-do, and Jeollabuk-do provinces and in Incheon, South Korea. The species is characterized by ten stamens, deeply serrated leaflet margins, and long horizontal pilose stems. A Korean name, Gorovoi-jip-sin-na-mul, for the species is newly given, and a taxonomic description of the species and key to four Korea native Agrimonia taxa are presented.

울릉도의 식물상은 총 109과 355속 526종 2아종 89변종 10품종 총 627종류(Taxa)로 파악되었다. 현재까지 보고된 울릉도 식물상은 총 122과 465속 762종 5아종 178변종 21품종 9교잡종 총 975종류로 정리되었다. 울릉도에 분포하는 식물의 특성을 밝히기 위하여 한반도, 울릉도 및 일본열도 간 식물상을 비교한 결과, 울릉도의 식물은 한반도와 더 유사한 관계를 보이는 것으로 밝혀졌다. 울릉도에 자생하는 특산식물을 포함하여 희귀 및 멸종위기식물의 서식처는 보다 체계적인 관리가 필요하다. 또한, 관광객의 증가로 귀화식물이 점점 늘어나고 있는 추세이므로 외래종에 대한 관리가 필요할 것으로 판단된다. 울릉도의 특정 생태계나 특산식물을 포함한 희귀 및 멸종위기식물의 서식처를 보전하기 위하여 생태계 보전지역 이상의 수준에서 보전지역으로 지정하여, 점차 파괴되어 가는 울릉도의 자연생태계를 보호해야 할 것이다.

The flora was summarized as 195 taxa; 73 families, 138 genera, 168 species, 23 varieties and 4 forms in Jangsoo-ri windbreak forest and 151 taxa; 63 families, 118 genera, 131 species, 18 varieties and 2 forms in Pyeongsa-ri windbreak forest. Based on the list of the rare plants by the Forest Research Institute, 3 taxa and based on the list of Korean endemic plant 4 taxa were recorded in the studied areas; Puccinellia coreensis (Gramineae), Asarum maculatum (Aristolochiaceae), Prunus yedoensis (Rosaceae), Koelreuteria paniculata (Sapindaceae), Adenophora triphylla var. hirsuta (Campanulaceae). The Specific Plant Species which is categorized by the Ministry of Environment, Korea, was summarized as 23 taxa for the 1 degree of 17 taxa, 3 degree of 5 taxa, 5 degree of 1 taxa in Jangsoo-ri windbreak forest and 22 taxa for the 1 degree of 18 taxa, 3 degree of 3 taxa, 5 degree of 1 taxa in Pyeongsa-ri windbreak forest. From the enlisted the flora surveyed, the naturalized plants were 17 taxa in Jangsoo-ri windbreak forest and 19 taxa in Pyeongsa-ri windbreak forests with the Naturalization rate was 8.7 percent and 12.6 percent, respectively. In Jangsoo-ri windbreak forest, there has been occurred many man-made impair and development without legal institution and control. So, it needs in haste institutional conservation measures and systemic database construction about function and necessity of windbreak forest. In Pyeongsa-ri windbreak forest, recently many people visited here. So, if we make eco-tour place connecting nearby coast and windbreak forest, it will contribute resident's economic profit and opportunity, concerns about windbreak forest, and necessity of conservation measures. Recently, the windbreak forests in Jangsoo-ri and Pyeongsa-ri should be bereaved windbreak forest of function by the human activities.

A village grove is the one fostered and protected for a district's traditional life near the vicinity of a ruderal village. This research is done to grasp potential natural vegetation, to use a basis data needed for its management and preservation as well as restoration project by examining the vegetation and flora targeting a village grove of the southern district of Gyeonggi-do which has been seriously damaged subsequent to a rapidly progressing city development. According to the survey, there appeared an outgrowth flora of Pteridophyta consisting of 69 families, 136 genera, 20 varieties, 3 forms, 170 species-totalling to 193 taxa. Urbanization index was revealed to 4.55% and naturalization rate 6.74%. In life-cycle pattern, perennials were found to show the highest distribution rate; in infiltration-multiplication strategies, human wave tactics type was found to be the highest 51%, consisting of 98 species, and naturalization rate also was revealed to be 6.74%. The vegetation unit was divided into a total of 11 patterns, such as a community of Pinus densiflora community, Pinus densiflora-Pinus rigida community, Pinus densiflora-Castanea crenata community, Pinus rigida community, Pinus rigida-Castanea crenata community, Pinus rigida-Quercus acutissima community, Castanea crenata community, Castanea crenata-Quercus acutissima community, Quercus acutissima community, Quercus acutissima-Robinia pseudo-acacia community and Robinia pseudo-acacia community. Quercus acutissima community is of a community type dominated by Quercus acutissima, in place of Pinus densiflora community selected by natural succession.

Wind holes or air holes, from which cool air blows out during the summer, but mild air comes out during the winter, have provided the phytogeographically important refugia for cryophilous or cold-loving boreal flora during the Holocene period. At present, wind holes are serving as a faraway disjunctive habitat for Pleistocene relict glacial floristic elements, and present an invaluable information to reconstruct the natural history. Present work aims to collate the nationwide distribution and relevant DB on the potential wind holes of Korea based upon media and literature sources, along with geographical informations, such as place name, topographic map, environmental geographical information, flora, monitoring data of Korea National Arboretum, and field survey data. Geographical information on sixty nine wind hole sites have compiled and analyzed on the basis of flora and presence of fossilized periglacial landforms, such as talus, block field, and block stream, and sixteen sites have thereafter carefully selected and scrutinized through field surveys. To maintain a sustainability of wind hole ecosystem, including their original landform, micro-meteorological phenomena and plant community therein as a refugia or habitat for relict plant species of Pleistocene glacial period, appropriate restrictions and preservation measures are required.
