최근 범지구적 문제가 되고 있는 지구온난화와 이로 인한 서식처의 환경변화는 고위도 지방의 식물이나 고산식물의 생존에 중대한 문제가 되고 있다. 본 연구는 강원도 태백산맥 고산지대에 분포하는 환경부지정 멸종위기종인 한계령풀 10개 집단에 대해 서식지와 분포 특성을 조사하기 위해 수행되었다. 한계령풀은 고도 940m~1,350m 의 범위에 분포하였으며, 이는 온도기후적으로 온량지수 (WI) 53℃·month~WI 75℃·month에 해당하여 냉온대북부림대에 속한다. 이 종은 5˚~23˚ 경사의 북동사면에 주로 출현하였다. 한계령풀 분포지의 교목층은 신갈나무, 거제수나무, 층층나무, 고로쇠나무가 우점 하였으며, 관목층에는 고추나무, 물참대, 국수나무 등이 우점 하였다. 한계령풀 집단의 초본층 종다양도(Shannon's Index)는 0.21에서 0.98이며 각 집단에서 한계령풀의 중요치는 개화기에 가장 높은 값을 나타내었다. 서식지의 특성에 대한 본 연구는 한계령풀의 보전과 복원 전략의 수립 결정에 중요한 기초자료로 이용될 수 있을 것이다.

Although Guleopdo is small island of only 1.71 ㎢, the endangered butterfly species, Argynnis nerippe, is abundant there. This study was carried out to estimate the abundance of A. nerippe in Guleopdo, using quadrate, mark-recapture, and line-transect methods. Although the study was insufficient, the population size was estimated at 4,467 to 6,700 larvae and approx. 1,000 adults. A. nerippe was the most abundant among butterfly species in Guleopdo, and it comprised 32% of the total butterflies. A total of 28 butterfly species were observed in this study, and 3 species of these species were migrating species. When the abundance of A. nerippe throughout the country during the period from 1938 to 2010 was studied, we found that it decreased abruptly in the 2000s. Presently, A. nerippe inhabits a few locations in the mid-northern region and western islands. The relatively high numbers of A. nerippe in Guleopdo was due to conservation of natural grasslands and grazing of livestock, which provides adequate habitat for this species.

This survey was carried out to investigate herpetofauna in 22 Islands, Incheon. As a result, we have listed 1 order, 5 families, 10 species of amphibians and 1 order 4 families, 12 species of reptiles. Of them, legally protected species are following: Elaphe schrenckii Strauch (Colubridae), Eremias argus Peters (Lacertilidae), Rana plancyi chosenica Okada (Ranidae), Kaloula borealis (Barbour) (Microhylidae). Especially, E. schrenckii was the most abundant in Island Seongap. Islands where endangered species have been found could be protected from further anthropogenic activities.

The International Union for Conservation of Nature and Natural Resources (IUCN) considers the western/lowland bongo Tragelaphus eurycerus eurycerus to be a threatened species, and the eastern/mountain bongo Tragelaphus eurycerus isaaci an endangered species［1］. Although extinction is considered by many biologists to be a natural process during evolution, the exponential growth of the human population has drastically and prematurely reduced the numbers and genetic diversity of many species［2］. Species have evolved to adapt to a specific habitat or environment that meet their survival needs. Alteration or destruction of their habitat results in a species becoming incapable of adapting and hence becoming threatened with extinction. A widespread scientific and public consensus has emerged suggesting that governments should assign high priority to the maintenance of biological diversity via habitat preservation and management far species conservation［3］. Unfortunately, the loss of biological diversity far surpasses the available conservation resources and species are lost forever on a daily basis［4］. Notwithstanding the focus on habitat preservation and wildlife management, conservation biologists have also become increasingly interested in using the technologies of reproductive and developmental biology to help manage or rescue endangered species［5］.

본 논문에서는 현행 우리나라의 희귀 및 멸종위기식물의 평가에 관한 몇 가지 문제점을 살피고, 이러한 문제점의 제시와 함께, 최근 I. U. C. N. 의 S. S. C. 에서 시안을 작성 중인 희귀 및 멸종위기식물에 대한 새로운 분류안에 대한 내용을 소개하였다. 본 시안에 의하면 멸종종, 자생지 멸종종. 멸종위기종, 위기종, 취약종, 민감종, 안전/저위험종, 자료 불충분종 및 미평가종 등 모두 9개 분류군으로 구분되어 있다. 본 시안이 더욱 다듬어지고 공식화되기 위해서는 앞으로 얼마간의 기간이 소요되리라 판단되며, 이 같은 움직임을 염두에 두고, 앞으로 우리나라의 희귀 및 멸종위기식물에 대하여 보다 구체적인 평가기준의 작성에 대해 관심을 가져야 할 것으로 믿는다. 아울러 새로이 도입된 몇 가지 용어의 우리말 번역에 대해서도 앞으로 충분한 검토를 거친 후에 통일을 기하는 것이 필요하다고 판단된다.

덕유산 국립공원 지역에 생육하고 있는 회귀 및 멸종위기식물의 서식처를 답사하여 그 생육상황을 조사하였으며, 복수초 군락 등 16종류를 대상으로 하여 기존에 우리나라에서 분류되어 사용되고 있는 분류결과와 최근에 작성 중인 회귀 및 멸종위기식물의 평가기준에 따라 재분류를 시도하였다. 본 조사에서 검토된 식물 종은 복수초 군락, 너도바람꽃, 구상나무, 주목, 뻐꾹나리, 왕괴불나무, 금강애기나리, 누른종덩굴, 백작약, 개불알꽃, 노각나무, 흰참꽃, 등대시호, 한라부추, 솔나리 및 감자난 등 모두 16종류였다. 이들을 I.U.C.N.의 S.S.C.에서 마련 중인 회귀 및 멸종위기 식물의 평가기준을 적용하여 재평가한 바 Endangered (E)에 해당하는 종으로는 너도바람꽃, 구상나무, 주목, 뻐꾹나리, 백작약, 노각나무, 흰참꽃, 등대시호, 솔나리 및 감자난 등 10종이, Critical (C)에 해당하는 종으로는 왕괴불나무, 누른종덩굴, 개불알꽃, 한라부추 등 4종이, Vulnerable (V)에 해당하는 종으로는 복수초와 금강애기나리 등 2종이었다. 상기의 구분은 기존에 우리나라에서 분류되어 알려져 있는 구분과는 약간의 차이가 있었으며, 이들 식물종들의 관리보전계획을 위해 앞으로 더욱 검토, 보완되어야 하리라 판단된다. 덕유산 국립공원내에 생육하고 있는 보전대상 특정식물은 주로 등산로변이나 개발계획지 등지에 거의 무방비 상태로 노출되어 있어서 앞으로 더욱 훼손될 가능성이 높은 것으로 판단되었다.

This research was performed to develop seminal propagation method of Saururus chinensis (Lour.) Baill. by conducting a rigorous germination study. Well-selected seeds were dry-stored at 4 ± 1.0℃ during the experiment. To study dormancy type, non-stored seeds were analyzed by embryo observation, germination test and detecting for any difficulties in seed coat to absorb moisture. Then to improve germination, seeds were submerged for 24 hours in a solution of varying concentrations containing one of plant growth regulators and minerals. According to research, fleshly matured seeds had an undifferentiated embryo and had a low germination rate below 5%. In addition, water submersion led to moisture absorption, embryo in the seeds grew and germinated so it was deemed morphophysiological dormant seeds. Percent germination (PG) and germination energy (GE) was greatly improved by soaking in plant growth regulators and minerals for 24 hours. Especially, 500 ㎎/L GA3 treatment resulted in the highest GE as 46.1%. KNO3 meaningfully improved PG (54.3∼57.7%) at 10∼20 mM but effect of minerals on germination acceleration as GE were negatively impacted in all concentrations.

The plant Empetrum nigrum, valued in the traditional system of medicine, is well known for its antibacterial, antifungal, and antioxidant properties. In the present work, the effect of removal of shoot apical meristem (SAM) on shoot proliferation was studied. It was observed that removal of SAM promoted shoot proliferation whereas intact tip resulted in higher survival percentage. Further, the effect of different concentrations of BA on above was also studied. During root formation the effect of light quality after treatment with IBA was investigated. For rooting, continuous red light without IBA resulted in maximum rooting percentage. The above factors when taken into consideration during micropropagation of this endangered plant can result in healthier plantlets. The results show that the species could be successfully conserved by in vitro propagation system.

This study was conducted to establish the optimal condition for conservation of genetic resources and micropropagation of Lilium cernum. Induction of bulbet of L. cernum was highly effective (9.2 bulb/explant) on 1/2 SH (Schenk and Hildebrandt) medium supplemented with 1.0 mg/L TDZ (Thidiazuron) and 0.1 mg/L NAA (Naphthaleneacetic acid). The treatment of 0.1 mg/L NAA increased root development (6.4 root/explant) under the in vitro condition. In addition, treatments of AC (Activated Charcoal) and ventilation were enhanced to develop number of shoots and to elongate length of leaf, bulb and root. Futhermore, the process of short-term soil acclimatization was promoted to strengthen the plantlets induced under the in vitro condition.
