This study was conducted to analyze growth characteristics and adaptability of poplar clones under the treatment of liquid pig manure. The average of survival rate was 33% better at control than the treatment under age of 5 years. But, tree height and DBH growth were higher at the treatment than control. Populus euramericana ‘Eco28’ showed the highest survival rate (97.9%) under the treatment. P. euramericana ‘Eco28’ and P. deltoides hybrid ‘Dorskamp’ could be selected as superior clones for height and DBH growth under the liquid pig manure treatment. The above-ground biomass production was also investigated when the poplar clones were 5 years old. The aboveground biomass under the liquid pig manure treatment was, on average. 52.6 ton/ha, which was 80% higher than control (29.1 ton/ha). P. euramericana ‘Eco28’ (73.6 ton/ha) and P. deltoides hybrid ‘Dorskamp’ (71.1 ton/ha) showed superior biomass production than other clones at the treatment of liquid pig manure. Based on survival, growth and demage traits, the adaptability of poplar clones to liquid pig manure treatment was estimated. P. deltoides hybrid ‘Dorskamp’ and P. euramericana ‘Eco28’ showed better adaptability to the treatment. P. nigra × P. maximowiczii ‘62-10’ and P. koreana × P. nigra var. italic ‘Suwon’ were identified as poor adaptability clones.

생물다양성을 보전하기 위하여 생물의 서식처가 되는 주요 지역을 생태계 보호지역으로 지정하여 관리하고 있다. 보호지역의 생물다양성의 보존 및 확보 전략 수립에 타당성을 부여하기 위해서 보호지역 간 생물다양성을 상대적으로 평가할 필요가 있다. 본 연구에서는 산림생태계에 해당하는 보호지역의 생물다양성을 객관적으로 비교할 수 있는 평가지표를 선정하였고, 이를 지리산 국립공원과 북한산 국립공원의 생물다양성 비교에 적용하였다. 평가지표를 선정하기 위해서 문헌 조사를 실시하였다. 언급된 빈도가 높은 지표들과 산림 생물다양성에서 중요한 역할을 하는 산림구조를 평가지표로 선정하였다. 이를 통해 선정된 평가지표는 총 7개로 종다양도, 종풍부도, 균등도, 희귀성, 교란종, 고유생물자원 및 산림구조이다. 지리산 국립공원과 북한산 국립공원에서 종다양도는 3.492와 2.943, 종풍부도는 8.998과 9.793, 균등도는 0.849와 0.680, 희귀성지수는 11.976과 10.783, 교란종지수는 0.214과 0.357으로 나타났다. 두 국립공원 모두에서 고유생물자원은 풍부하게 나타났다. 산림구조는 다양한 임상을 보이고 안정적인 4층 구조를 이루고 있으며 수관울폐도는 지리산 국립공원에서 더 높게 나타났다. 대부분의 평가지표에서 지리산 국립공원의 생물다양성이 북한산 국립공원보다 높은 것으로 평가되었다. For conservation of biodiversity, we designate and manage the major areas that are habitats of organisms as ecosystem protected areas. It is necessary to evaluate the biodiversity of protected areas relatively in order to establish strategies to protect and secure the biodiversity of protected areas. In this study, we selected evaluation indicators by which we can compare objectively the biodiversity of protected areas corresponding to forest ecosystem, and applied them to Mt. Jiri and Mt. Bukhan National Parks. We reviewed literatures to select evaluation criteria. Frequently mentioned criteria and the structure of the forest which plays an important role of forest biodiversity were selected as the evaluation criteria. As the result, the selected evaluation indicators were 7 - species diversity, species richness, evenness, rarity, disturbance species, indigenous species, and forest structure. In Mt. Jiri and Mt. Bukhan National Parks, species diversity were 3.492 and 2.943, species richness were 8.998 and 9.793, evenness were 0.849 and 0.680, rarity were 11.976 and 10.783, and disturbance species index were 0.214 and 0.357 respectively. Both national parks had abundant indigenous species and showed various forest physiognomies and stable 4-layer structure. It was found that crown density was higher in Mt. Jiri. Most indicators were implied high biodiversity in Mt. Jiri and Mt. Bukhan national parks.

Studies on forest tree breeding (FTB) in South Korea started in the 1950s and have achieved remarkable outcomes through various techniques and methods such as selective breeding, cross breeding, introduction breeding, and biotechnology. Despite these outstanding achievements, no attempt has been made to objectively and quantitatively evaluate the results of domestic FTB research. Here, we quantitatively analyzed past research trends using keywords of published journal papers and compared the current domestic research level of FTB with the international level. Using various keywords in this field, we searched for research articles published in the Journal of Korean Society of Forest Science, the Korean Journal of Breeding Science, and the journals listed on the Science Citation Index from 1962 to present. The analysis of these studies showed that the research on FTB has grown quantitatively in Korea, and has been conducted on various subjects. Research topics from Korea, in terms of purpose and species, are not significantly different from those of foreign countries. The genus Pinus has been the major subject of FTB studies both domestically and internationally. However, in foreign FTB research, the trees used for research have diversified each year, while they were not diverse in Korea. The FTB research capacity of Korean national institutions, such as the National Institute of Forest Science, continues to dramatically increase, while the research capacity of universities is relatively low. Based on the results of this analysis, it is necessary to establish a concrete and effective policy for future research and development of FTB.
