BACKGROUND: The Geomunoreum Lava Tube System (GLTS) is both vast and culturally valuable. The Jeju Volcanic Island and Lava Tubes, which are partly composed of the GLTS, have been declared as a United Nations Educational, Scientific, and Cultural Organization (UNESCO) World Heritage Site. Exploration of the caves is strictly regulated to conserve these vulnerable environments. Photographs provide limited information and do not describe the entire environment comprehensively. Therefore, we created several illustrations of the lava tubes to display their environmental features. METHODS AND RESULTS: We explored six lava caves (upstream and downstream) in the GLTS and photographed their geological features and yellow walls, the colors of which are influenced by microbial mats. We compared the hex codes of the wall colors using the Clip Studio v1.10.5 software and created illustrations that accurately represent the scale and features of the caves. CONCLUSION(S): Upstream and downstream caves of the GLTS differ in scale and volcanic features. We illustrated various characteristics of the caves including lava cave features, vegetation, and microbial mats. We also described the internal and external cave environments.

Different actinomycete strains were isolated from natural lime caves of Ondal Chemongok Hwanseon and Yongyeon which are located at Kangwon or chungcheongbook province in Korea and were identified to the genus level. Soil sam-ples were collected at 6 sites inside and 2 sites outside of each natural lime cave, As the result the strains belonging to genus Streptomyces and rare actinomycetes were isolated at the average of 2.1 and 3.4 strains per g soil on inside cave whereas which were isolated at the 6.0 and 1.8 strains per g soil on outside cave. How-ever the generic distribution of Streptomyces and rare actinomycetes isolated from outside cave was quite dif-ferent from that of inside cave. It was shown that rare actinomycetes at natural lime caves is generally highly abundant than Streptomyces.

During the year and a half of preparation for the Untnmed Ri Expedition (Caves $ Caving 29 p. 29) a lot of time was devoted developing the techniques we would use to explore the roaring wh waters of Nare. We finally left for New Britain with a whole new set caving rules and hardware which would not be out of place in an Indi Jones movie. The first serious work to tackle this new problem in caving wa pioneered by the French in 1978 after the discovery of the Nare. M and Kavakuna - all big river caves with flows of 15-20 cumes. We tir out these techniques on the white water rivers of north Wales. ma some improvements and tested some new ideas. This articles is a summary of our research and experience.

Five species of Tomoceridae from Korean caves are reviewed , including one speices described as new to science. T. (M.) odongnyeoensis n.sp. belong to the subgenus of new record for Korea. The present study eventually resulted in listing eight species in five subgenera of Korea cave Tomoceridae, and all Collebola from Korean caves nowenumerate 23 species (or subspecies) in nine genera of eight families.

Internal and external resources of Cave were classified by type. For tourists, caves are important but surrounding environment of caves is more important.

Unlike conventional cave classification, this paper is attempted to classify caves in Korea in considerations for the surroundings. As a result, it‘s been confirmed that a cave can maximize the effect of information delivery as a part of great tourism resources. It‘s also been confirmed that the characteristics of caves can be differently interpreted depending on the size of surrounding humanistic environment as well as the size of the cave.

Caves abd the life they contain face constant pressure from a worldw demand for cement. hydro-electric power and land for building a agriculture. The 8th International Congress of Speleology held in Kentu two years ago passed a resolution on behalf of the IUCN "Cave Speci Group" which called for "...biological surveys of threatened caves. mos in the tropics, and ecological studies to solve specific managem provlems on the causes of endangerment and how these can be remov or mitigated". This final article in the "Cave Life" series explains the n for an ecological approach to cavelife conservation.

This is but a brief description of a cave which, although well known to local inhabitants, appears to be unknown to the N.Z.S.S. It is reputed to be one of several caves in this region, but we have so far been unable to continue our prospecting here as fully as is needed. The cave is in no way unique nor of an outstanding nature; being within an isolated remnant of a much younger limestone which appears to have once extensively overlain the old Paleozoic basement rocks of the Aorere valley region. It seems probable that it is in the same limestone as the well-known Te Anaroa tourist cave, at Rockville near Collingwood, and that of the Brown River caves south of Bainham.(omitted)

1. Stafford's Cave, named by the miners because a former visitor, Mr. Stafford, broke his leg in it, is the most northern of the three caves. The entrance lies concealed in the undergrowth, but is otherwise wide and open. A steep conical shaft leads down for a depth of about 80 ft from the floor of the cave; at the bottom, rammed in between the two walls, lies a great block of limestone below which a rivulet streams forth, flowing through the cave, which runs from east; in the cave it is joined by a little tributary.(omitted)

The mountains and rivers in Guilin are famous for their beauty; the pines and rocks on Huangshan Mountains are well known for their magnificence. And now, another famous scenic zone that shall be one of the wonders of the world located in remote area of Northeast of China appears quietly, and it attracts lots of tourists and makes them reluctant to leave. That is Huanren, a Manchu county, which is famous as miraculous place.
