Biological collections in 72 depositories of South Korea were surveyed. The number of specimens attained 5 144 409 in total, consisting of 4 103 000 animals, 1 034 825 plants and 6 584 fossils. The average numbers of specimens and species for each collection were 71 450 and 1 130 respectively. The most frequent were in the class range of 10 000-50 000 specimens and 0-100 species each. Twenty one of 45 depositories answered that 80% of their collections are well managed. As regards documentation, only 24% of the collections were electronically databased. The number of species represented by type specimens in the collections and taxonomic experts turned out to be 577 and 207 each. Considering the deplorable situation of the collection status, it is strongly suggested that immediate actions for capacity building by networking databases of the collections, man-power training and setting up of the National Museum of Natural History are urgently needed to provide resource base for biodiversity assessment as well as to respond properly to the Convention on Biological Diversity.
Hitherto a total of 11 853 species with 504 families under 30 orders of insects have been recorded in Korean fauna. It estimates that a total of 1 500 000 insect specimens have been deposited throughout Korean institutions. 2 500 000 insects specimens or more from Korea is deposited in world institutions.
Many wild Korean plant species have become endangered mainly due to human activities, and particularly the Korean war in the early 1950's, as well as by the rapid industralization in the 1960's. Other major threats come as a result of human impacts, such as the mass illegal collections in the wild for medicinal or ornamental purposes and habitat disturbances due to recreational activities The present conservation activities of Korean rare and endangered plant species were introduced. Among the species in the wild of Korea, the conservation criteria were applied to evaluate the conservation values. Habitat or species restoration for rare and endangered species were applied for some species in Korea, and these works will increase dramatically in the near future. Modern methods of recovery plan for Abeliophyllum distichum NAKAI, Oleaceae, to restore the wild habitats was also introduced.
The status of the exploration of Collembola Poduromorpha of the Korean Peninsula is described, in connection with the biogeographical distribution of species.
In the Korean peninsula, 1 472 species of vertebrates are listed (960 fishes, 15 amphibians, 29 reptiles, 383 birds, 85 mammals): among them 48 species are designated as natural monuments (4 fishes, 38 birds, 6 mammals) and 116 species, endangered species (29 fishes, 4 amphibians, 8 reptiles, 54 birds, 21 mammals). Moreover, 116 species (24 fishes, 9 amphibians, 13 reptiles, 50 birds, 20 mammals) are designated by the Ministry of Environment as the vertebrates of special protection. Total number of publications on biological researches using Korean vertebrates are 946 papers (fishes, 464; amphibians, 90; reptiles, 42; birds, 194; mammals, 156). But the researches on the conservation of biological resources are at basic level: 57% of the papers are related to the reports on the list of local fauna and traditional taxonomy, and only 13% of 87 endangered species in tetrapods were studied, but still in a very limited scope and depth. In Korean rodents, many systematic papers were published using methods ranging from morphometry to DNA systematics, but a few international cooperational researches were carried out. All of Korean rodents are one or two subspecies of the species inhabited in the Eastern Asia or across Eurasia, and it is necessary for the conservation of Korean rodents to carry out international researches with the cooperation of many foreign mammalogists.
Two new species of the genus Iotonchus and Coomansus zschokkei (Menzel, 1913) are described and illustrated. Iotonchus uisongensis sp. nov. is 1.5-1.6mm long, a=23.0-26.0, b=2.8-3.2, c=17.1-19.4 (female) and 19.6-23.0 (male), V=67.0-73.0, buccal cavity=52.0-63.0 x 31.0-36.5 µm, spicule 75.0-92.0 µm long, ventromedian supplements papillae 20-22 in numbers, and is characterized by having not protruded labial papillae, supra basal dorsal tooth, and flattened basal oblique plates of buccal cavity. Iotonchus damsanensis sp. nov. is 1.6-1.7mm long, a= 19.7-22.0, b=2.9-3.0, c=17.2-21.7, V=71.0-74.5, buccal cavity=58.0-61.0 x 35.0-37.0 µm, and is characterized by having offset lip region, well protruded labial papillae, basally tapered buccal cavity, and in having pre-vulval papillae. Coomansus zschokkei reported here for the first time from Korea is also described in detail with variation in the shape of male tail.
