  • Present problems of the Korean rare and endangered plant species evaluations are discussed. It is proposed that the evaluation criteria for Korean rare and endangered are urgently needed in the future. The translation of new proposed criteria into Korean should be discussed in order to avoid confusion in the future. The draft of a new criteria system for rare and endangered plant species. prepared by the S. S. C. (Species Survival Commission) of I. U. C. N (International Union of Conservation of Nature) are introduced. The proposed draft for the criteria being developed by the S. S. C. of I. U. C. N. are Extinct, Extinct in the Wild, Critical, Endangered, Vulnerable, Susceptible, Safe /Low Risk, Insufficiently Known, and Not Evaluated. It is expected to take the more time to be technically developed further and also officially recognized by the I. U. C. N. for the practical use in the future.

  • The purpose of this study is conducted to examine the change of flora and fauna in the extensive rooftop green area from 2005 to 2009. The experimental site is on the rooftop green area of Seoul Women's University which was constructed in 2005. This research was consisted of four parts: soil, potted plants, invading plants and small animals especially insects. The plants were surveyed by enumeration, while animals were surveyed by two methods which are 'Netting and Searching' and 'Pit fall trap'. The initial group of plants planted in 2005 was 100 species of 26 families whereas in 2009 there were 62 species of 23 families including 22 invading species of 11 families. In case of insects in 2009, 21 species of 7 families (9 orders) were detected; 19 species of 15 families (8 orders) were discovered by 'Netting and Searching' and 5 species of 5 families (5 orders) by 'Pit fall trap'.

  • This study investigated the dominant species and the population variation of the ant species, an indicator species of biodiversity, to obtain basic data on the changes of population according to the future climate change. The survey period was from June to September 2013, and we investigated the distribution of ants by square irradiation method (10m × 10m) using traps. The survey in each altitude identified a total of 14 species of 11 genera in 3 subfamilies and collected 15,466 individuals. We confirmed the distribution of 4,548 individuals of 13 species at low altitude (700m), and the dominant species was Aphaenogaster japonica (49.9%). At the middle altitude (900m), we collected 9,129 individuals of 8 species, and the dominant species was Pheidole fervida (57.7%). At high altitude (1,100m), we identified 1,789 individuals of 10 species, and Myrmica kotokui (43.3%) was the dominant species. It was confirmed that Aphaenogaster japonica, Nylanderia flavipes, and Pheidole fervida were widely distributed throughout the altitudes.

  • A survey of Hongryu-Dong and Chi-in district. Gaya National Park, was conducted using 40 sample sites of 500$m^2$ size. TWINSPAN classification confirmed a complex pattern of both local and geographical variation in the vegetation: Dry and wet community types. Within dry community types, two floristic assocation of Pinus densiflora were defined according to local variation. Within wet community types. two floristic association were defined according to altitude. Those associations can be further subdivided floristically into eight subassociation. The vegetation pattern presented by DCA ordination corresponds to one of TWINSPAN at the first two division. The DCA ordination was successful in separating Pinus densiflora from broad leaf forest. Ordination of samples produced arrangements reflectly environmental gradient of soil. The correlation between the first axe of DCA and soil moisture, soil acid, altitude, maximum species diversity and species diversity was significantly negative. The similarity index between each community was very low level.

  • To search for myrmecochorous plant species in Korea and their diaspore characteristics, the flowering and fruiting of herb species, collectiong their fruits and diaspores, and the related ant species were studied from April to September 2011. Twenty-four herb species growing in Korea prove myrmecochorous (seed attached elaiosome) plants. Elaiosomes of 24 herb species vary considerably in shape and size. Major ant species transporting the diaspore of myrmecochorous plants are Formica japonica, Lasius alienus, Tetramorium tsushimae, Temnothorax koreanus, Lasius japonicus, but Camponotus japonicus and Paratrechina sakurae do not transport the diaspores. This study found out that mutualism between myrmecochorous plants and ants is carried out in Korea. Further study on the myrmecochorous plant and related ant species, cafeteria experiments should be needed.

  • This study was conducted to investigate to compare avifauna at Taegosa area in Pukhansan with Kamapong area in Inje-gun, Korea. The observed birds at Taegosa in Pukhansan and Kamapong area were 35 individuals on species and 113 individuals on 29 species respectively. In Pukhansan area, there was severely avifauna diminishing in July in which users were concentrated. Pica pica sericea and Streptopelia orientalis orientalis were observed the dominant species in Pukhansan area and Kamapong area respectively. There were two species of national monument in these surveyed area, Otus scops stictonotus in Pukhansan area and Falco tinnunculus interstinctus in Kamapong area. Cuculus saturatus horsfields, Cuculus micropterus micropterus and Eurystomus orientalis calonyx were found out in Kamapong area to the rare bird. Species diversity and avi-ecosystems in Kamapong area were seemed to good, whereas in Pukhansan area, there was relatively poor avifauna caused by isolating with surrounding ecosystem, overusing by visitors beyond capacity and heavy acid rain. Therefore avifauna protection plans sould be made and carried out for Pukhansan National Park by thorought study with experts.

  • This study was to investigate the user's effects on the avifauna in Sokri Mountain National Park. The survey was carried over 4 districts which were divided with main trail(valley, ridge), subtrail(ridge), un-used trail (valley) by line transect method from December 1989 to October 1990. The observed birds were 36 species and 570 individuals, these consist of 23 species for residents. 7 species for summer visitor. 2 species for winter visitor, 4 species for passage migrant. The average density of birds was 2.35 ea/ha., and main dominant species were Parus major minor, Porus palustris hellmayri, Parus varius varius and Sitta europaea amurensis in order. The observed frequency of wild birds was 3.4 times/km in average. No. of species, species diversity and observed frequency of summer and autumn were lower than winter and spring in 4 survey routes. Therefore, from now, in Sokri Mountain National Park manegement, the enjoyment oriented activities will be regulated and control of trail use on main trail are necessary during breeding periods of wild birds protection, especially in summer.
