The discussions took place at the recently established Nor wegian Arboretum near Bergen - "Arborete pa Milde".The committee was assigned to solve the problems common to the Nordic Arboreta and exeeding the ability of the single arboretum. Since it was found that in the Nordic collections many earlier plantations had been made with material of unknown origin or from very limited sources the highest priority was given to collection of plant material for the Nordic arboreta from not represented or only slightly represented areas. The distribution of "collecting areas" to the different member countries was as follows: Denmark: The Southern part of South America. Finland: Northeastern continental Asia. Norway: New Zaeland, Tasmania and South East Australia. Sweden: Japan. The main purpose of the collecting expeditions was to supply the Nordic arboreta and other research institutes with plant material of well defined origin, especially seed It was also thought, that for particularly interesting species series of collections should be attempted in order to provide material for provenance experiment, an activity rarely earlier carried out with dendrological or ornamental plants . The expedition to the Republic of Korea v?as arranged by the Finnish Forest Research Institute, Max. Hagman, professor 3 of forest genetics in close cooperation with Lars Feilberg, lecturer at the Horsholm Arboretum, Denmark, Jan E. Sanda, research assistant at the Agricultural University of Norway and Thomas Lagerström, lecturer at the Agricultural College of Sweden. The expedition was made possible by grants from the Nordic Cultural Foundation (Nordisk Kulturfond) and the Danish National Bank (Nationalbankens Jubilaeumsfond af 1968). We wish to thank these foundations for their valuable support. The Norwegian shipping company The Wilhelmsen Lines, Oslo kindly supported the expedition by offering transport of the collected material in special cold stores . Shipowner Tom Wilhelmsen expressed from the very beginning a great interest in the expedition and supported its members personally in many ways. At the time the first formal contacts were made with the Republic of Korea, most valuable help was given by His Excellency Ambassador K. D. Yoon, Embassy of the Republic of Korea, Helsinki. The excellent technical planning in Korea was done by the Office of Forestry, Seoul and our most sincere thanks go to Director General Sohn, Soo-Ik who not only personally took great care of the wellbeing of the members of the expedition but also mobilized his staff at the Head Office as well as in the different Forest Regions for the many practical problems that had to be solved. The Office of Forestry also arranged for the permissions to collect in National Forests, National Parks and other protected areas where the most interesting vegetation was to be found, and provided the expedition with transport facilities in the form of two field-going big jeeps with drivers and also in the form of numerous porters in all the many 4 places where the expedition only could proceed on foot. Only those who have walked the Korean mountains can really appreciate what this means for the success of a botanical expedition . Of the officers of the Head Office we can only mention here Director Kim, Syung-Yup and Mr. Lee, Kyong-Sang the latter being invaluable in the arrangements of lodging, tickets, mail, local transport, customs etc. etc. thus smoothing our way in to us unfamiliar conditions. The expedition was very fortunate in being able to set up its headquarters at the Forest Research Institute in Seoul where Director Lee, Sung-Yong kindly provided us with office and laboratory space and did not mind at all our spreading of herbarium papers to dry all ower the front yard lawn of his institute. Despite his many duties Deputy Director Sim, Hung-Soo took time to follow the expedition on the first and third course thus helping us continuosly in many activities and providing us en route with information on Korean forestry and forest research problems and achievements. Seeds, silviculture and landscape architecture are at the FRI the responsibility of the Division of Reforestation and it was therefore clear that our presence put great strain on their activities. Nevertheless, the Division Chief Shim Sang-Yung and his staff met our various needs in a most satisfactory way. Particularly we have to mention Taxonomist Cho, Moo-Yun, Head Curator of the institutes Hong Nung Arboretum who followed us day and night on all our courses thus providing us with a "Walking Flora" to be consulted on taxonomic or plant geographical matters whenever needed. His help in checking our collections with his herbarium afterwards can 5 neither be overestimated. Mr. Cho was during our work assisted in an excellent way by his aide-de-camp, Field assistant Han, Sang-Bae whose great practical experience in seed- and plant collection and handling of the material in the field as well as in the laboratory was of very great help, not to mention his delicious cooking on rainy mountain sides as well as in sunny temple yards. In matters concerning genetics, provenance research and tree breeding the expedition was fortunate in being able to rely on the Institute of Forest Genetics in Suweon as well as on its branch station in Cheju-do. Director Choi, Jung-Suk and his numerous research officers helped us in many ways and we are very grateful to all of them. Our thanks also to Mr. Hwang, Jae-Woo who followed us on the field trip and Mr. Chung, Min-Sup, who, being a grantee at the Finnish Forest Research Institute, helped us in the preparatory work when the expedition was planned. Splendid scientific support was also obtained from the faculty members of the College of Agriculture, Seoul National Univer sity, Suweon. Professor Hyun, Sin-Kyu had helped the expedi tion already in the preparatory stages by providing references to literature and commenting on the suggested tour programme and in addition he was kindly quiding us when visiting expe riments with introduced exotic trees adding to our knowledge from his great experience in forest tree breeding during many years. Professor Yira, Kyong-Bin who followed us on the third course, broadened our background to the collection work by supplying basic information in his special field, Korean silviculture. He also gave us many valuable data on Korean forestry in general. Without the excellent help of Dr. Lee, Tchang-Bok, Professor of Dendrology, many a plant would have remained unidentified. 6 His life long experience of the Korean flora, gathered during innumerable field collecting tours all over Korea, formed an unmeasureable source of information from which the expedition gained every day he followed us on the second course. However, it must be admitted that for some of us it caused great difficulty to follow him up and down the gorges and tracks of Mt. Jiri-san, where he proved his reputation as a famous marathon runner. His many publications on Korean plants and their use, so generously given to us, will even in the future form a basic library in our work. Among the many other persons who helped us in Korea, we would here only like to thank Mr. Carl Ferris Miller for his great hospitality and for valuable discussions on Korean dendrology, a field in which he represents great expertise. We would also like to express our gratitude to Mr. W.D. Jones, General Manager of the Everett Steamship Corp. S/A, who helped us with the shipping business when our collections were sent home. And finally we would like to thank our ground staff at our institutions at home, who has taken care of the plant material and obviously will be very much engaged in it in years still to come . 7 PREPARATORY WORK IN FINLAND, DENMARK AND KOREA Korea has, since long ago, been of interest to dendrologists . It has a very rich flora despite the fact that its climate is more severe than in neighbouring Japan. Since many plants from Japan have been grown successfully in Scandinavian gardens, it could be thought, that plants from Korea would be more hardy and thus suitable for culti vation in the more continental parts of the Nordic countries Already E.H. Wilson (1928) pointed out that Korean plants are best suited for gardens where climatic extremes prevail because they enjoy a fixed climate in their homeland. In the earlier parts of this century Korean plants were imported into Scandinavia, and were in general growing surprisingly well, withstanding e.g. later such severe winters as 1939 - 1944. The material obtained was, however, limited in sources and in many cases the records about origin were missing or in complete. For a further development it was therefore considered necessary to try to carry out a collecting expedition having especially in mind the variation within species and trying to obtain as many samples as possible from a wide range of localities. It was also clear that on such an expedition new species which had not been tested before might be collected. Since Korea reaches from the Manchurian border in the North to the island of Cheju-do in the south a mere transect through Korea would have to cover a very long distance. This was not possible with the resources available and within the time that could be used for an expedition. Also other reasons made plans for an all-covering collection difficult. 8 Thus the original intentions of having collections through the whole of Korea had to be abandoned and the experiences from Northern Korea were limited to a short visit by one of us (M. H.) in 1974 to Pyongyan, Wonsan and Southern Kumgang san. In 1975 it was decided to concentrate the efforts to Southern Korea where the possibilities looked good. This decision was supported by the fact that a Finnish scientist had collected seeds in the Mur-river region of the USSR in 1974 and that there were promises for a Finnish expedition (which later also took place) to the same area in 1976. Thus at least a part of the northernmost distribution of many species occuring also in Korea could be covered and the planned expedition could concentrate on the south. The preparation started in 1975 when the first contacts were made with Korean scientists, and plans developed by correspondence.The arrival at Helsinki in 1976 of a forestry stipendiate Mr . Chung Min-Sup, B. For. Sci., facilitated greatly the detailed planning and study of Korean literature In the meantime the Arboretum at Hjzirsholm, Denmark, had been going throuh the dendrological and horticultural literature and selected lists of species of particular interest. These tentative collecting-lists were later checked by prominent experts in Denmark, Finland, Norway and Sweden. The Horsholm Arboretum staff was also preparing the equipment of the expedition, relying on recent experiences from the expedition to S. America. When ready, the expedition box was sent to Korea in the summer of 1976 by ship. During these preparations, the Korean authorities, both in Korea and abroad were most helpful and it was on their suggestion it was decided that the expedition should base 9 its work on transport and quidance provided by the Office of Forestry of Korea. It may now be noted that without this generous help the expedition would have been impossible. Since many of the plants of interest were growing in protected areas, the necessary permission had to be arranged beforehand and also at this work the Korean autho rities were most helpful. To speed up the handling of the material at home, permission were obtained for the rapid import of living plants under the supervision of the plant quarantine authorities in the countries concerned. Looking back, it would have been useful, if more time could have been allowed for the study of descriptions of Korean vegetation and plants. This was, however, seriously hampered by the fact that most of the pertinent literature is in Korean or Japanese. ITINERARY AND TIME TABLE (Note on transliteration: Two systems of writing Korean words in the western alphabet are currently seen in Korea. The McCune-Reischauer system is used in most publications. However, books and maps found in Korea may often employ the Ministry of Education system which has many spellings differing from the M-R system. We have not been able to transliterate all the various names into one of the systems, and it is regretted that confusion may result from this inconsistency in usage.)

The central Korean forest service department is the Office of Forestry under the Minister of Home Affairs. The main objects of the Office of Forestry are: - to establish and maintain forest protection - to enrich forest resources - to develop and improve utilization of forest products - to induce better management of forest lands through educa tion, instruction and research. The total forest land area (as per 1975) is 6 635 352 ha, of which 27,3% is national and public forest and 72,6% private forest. Of the total forest land 89% (5 980 693 ha) are stocked and 11% (646 876 ha) are unstocked. The stocked forest land consists of coniferous forest 54%, deciduous forest 18%. mixed forest 28% and a small area covered with bamboos. 3 The total stock volume is 105 352 000 m which gives an average growing stock of ca. 15,5 m 3 /ha. This low value is mainly due to the devastating effects of wars and shifting cultivation followed by erosion and pests and to the diffi culties the reforestation work is facing in this highly mountainous country. Reforestation work is, however, in good progress and the 16 target for reforestation and afforestation in the 10 year plan is 3 065 000 ha. Of these 625 000 ha has been planted by 1976. The annual plantation work har in the latest years been c. 100 000 - 130 000 hectares per annum. The reforestation concentrates in the beginning on erosion control, fast growing species for fuelwood, fruit and nut bearing species and in the long run species for timber pro duction . Forest management plans are prepared for all classes of forest ownership and the plans are approved by governement authority. The Shifting Cultivation Resettlement Law has improved forest management by creating policy for settlements, resettlements and reforestation. The Saemaul Undong movement has been successful also in forestry by inducing the right attitudes toward land-water and naturemanagement and proper handling of the forests. For the conservation of wildlife 12 national parks have been set up covering an area of 2 483 in total. More than 10 000 old and giant trees are protected as nature monuments . Research organisations under the Office of Forestry are the Forest Research Institute (F.R.1.) , the Institute of Forest Genetics (1.F.G.) and the Forest Resources Survey and Research Center. The Forest Research Institute was established in 1922 and conducts research in the fields of forest management, protection, reforestation, forest soils, utilization and processing of forest products and inspection of forest 17 products. The institute also conducts on-the-job training for governement forestry officials. The F.R.I, has a sta-ff of 129 officers and research assis tants of which 72 are research foresters. The institute has 3 branch stations and the Kwang-nung experimental forest has an area of 2 354 ha. In addition the institute has an arboretum at its head office in Seoul. The main objects of the Institute of Forest Genetics in Suweon are to study the heredity in trees, develop new varieties , improve vegetation and establish seed orchards. I.F.G. has a staff of 57 research foresters and 12 technical officers. The institute has 75 ha of nurseries and 2 408 ha of experimental forest and 3 branch stations. The total area of the seed orchards is 750 ha. Among the present objects of the I.F.G. are development of fast yielding species, species for fuel and erosion control, crop trees and the introduction of exotics and adaptability studies. Research is also carried out in connection with the higher education in forestry e.g. at the Seoul National University, College of Agriculture at Suweon. 18 Figure 2.

(Neg.nr 14/76:4). 19 KOREAN ARBORETA AND VEGETATION RESEARCH As early as in 1912 a forest nursery and experimental planta tions were established in the Kwangnung forest. Since 1922 intensive forest reseach including plantations of exotics have been going on there. Kwangnung is nowadays a branch office of the F.R.I. The plantations at Kwangnung include-also plots of Pinus silvestris and Picea abies of Danish and Swedish origin. Some of these plots have developed rather well but not so well as e.g. the endemic Abies holophylla. In addition to the plantations for forestry purposes there are also an arboretum and a section for edible plants, the later forming an important part of the products of Korean forestry. In Seoul the F.R.I, has the Hong-Nung Arboretum in which since 1922 has been planted a great variety of Korean plants As per 1971 (Cho, 1972) the collection included 635 genera with 1195 species of native plants and 112 genera with 157 species of introduced plants. Many species are in addition represented by several varieties and forms. The Hong-Nung Arboretum carries out collections all over the country and at the F.R.l.there is also a reference herbarium of 14 000 units and a collection of seed samples. The Head Curator of this arboretum is Dr. Cho Moo-Yun. 20 At the College of Agriculture in Suweon, professor T.B.Lee is at the present developing the Kwanak Arboretum which also operates a seed collecting and exchange system. The Kwanak Arboretum uses the reference herbaria of the College of Agriculture. At all branch atations of the research instituties there are smaller arboreta and the regional forest offices usually have demonstration plots and gardens at their headquarters. Botanical gardens were not visited by the expedition but are in possession of collections of trees and shrubs as well as of other plants. Mr. C. Miller / of Seoul, has a private arboretum in Chuuli-po on the western coast and he is particularly interested in Ilex. And finally on has to remember that Korean arboriculture is gaining much from the rich tradition of gardening at the temples ans imperial mausolei, many of which have plantations going back many hudreds of years. The study of the flora Korea, initiated by Palibin (1899, 1900,1901), rests well on the foundation laid by Takenoshin Nakai who worked with Korean plants from 1909 to 1952. The richness of the flora (3 176 species, 841 varieties and 174 formae; to quote Nakai, 1952) leaves, however, still room fore more work which is in good progress. Studies initiated by the late Dr. Chong Tae-Hyon and follo wed by his pupils and collegues have increased the know ledge of the plant geography of Korea. Especially the studies of the distribution of trees and shrubs on the different mountains of Korea are of great value for the dendrologist. 21 It is natural,that much of the new work is written for the Koreans themselves,but one who is interested in Korean plants still hopes for a recent Korean plant geography in a western language. 22 CLIMATE AND ECOLOGY The climate of Korea is determined by its latitudinal posi tion, its terrain and of the currents in the surrounding seas . The peninsular location of Korea on the edge of the land mass of continental Asia causes a decided variation between the cold of the winter and the heat of the summer, and the monsoonal center of North Asia located in Mongolia generates even more seasonality in the climate. Thus, winters are colder and summers are hotter than in other regions of similar latitudes away from the continental in fluence. The average January temperature in Seoul is as low as -4,9° C and minimum temperatures of -23,1° C have been recorded in the same place. The eastern coast, being separated from the west by mountains and effected by the warm currents in the Japan Sea, is warmer measured in annual average, than the west. The Korean winter is dry and cold, begins in December and extends into February-March.Spring starts in April and the hottest period of the year is beginning in early August and lasts for about one month. In the midlands (Taegu) temperatures of +4 O°C have been reached in this season. The rainfall during the season June-August is 50-60% of the annual total of 800-1000 mm. October-March is the dry period. Snow is nevertheless common in the winter. Korea has been divided into eight climatic zones but there 23 is in addition great differentiation geographically and in fact, each mountain valley and slope has its unique climate The zones of climatic variation that are dependent upon differences in elevation are in some places very well marked e.g. on Mt. Halla-san in Cheju-do. The greater part of Korean soil is made up of granite and gneiss. The soil is generally sandy and contains only 12- 37% of clay. In Kangwon-do limestones occur with the formation of terra rossa soils. The soils of Korea are greately influenced by the rain falls during the summer months when the weathered soil sur face is apt to be washed away, and many hills are eroded to a high degree. The Korean vegetation has been divided into five main zones which correspond also to the forest zones such as they are recognized e.g. by Uyeki (1933) . Along the southern coast and on the offshore islands exstends the warm temperate zone with broad-leaved ever greens such as Camelia, Cinnamomum and Quercus glauca. Bamboos of considerable dimensions can be seen growing in this region. The temperate zone, to which most of the southern Korea belongs might be divided in a southern part and a northern part . The southern area is characterized by Pinus densiflora, Quercus aliena, Q. acitissima, Carpinus cordata, Carpinus laxiflora and Zelkova. In the northern part, the Quercus - Abies belt, typical species are e.g. Quercus mongolica , Acer mono, Cornus contro- 24 versa , Tilia amurensis, Fraxinus rhychophylla, F. manchurica and Kalopanx pictus. Abies holophylla and A. nephrolepis are increasing towards the north and so is Pinus koraiensis. The cold temperate zone, the Abies - Betula belt is mainly situated in northern Korea but appears also at higher eleva tions along the Taebaek Mountains range such as at Mt. Seolag san, Mt. Doekyu-san, Mt. Jiri-san and even to a certain extent on Mt. Halla-san. Among the conifers of this zone are Thuja koraiensis, Abies nephrolepis and Pinus pumila in the northern part, Picea jezoensis isolated in the central part and Abies koreana in the central southern part. Taxus cuspidata is spread all over S. Korea.The hardwoods consist of several maples, Betula ermanii, Betula platyphylla, Betula schmidtii, Quercus mongolica, Sorbus amurensis,S. commixta. Characteristic for all Korean vegetation zones is the great amount of shrubs and climbers that exist in the ground layer and that, as soon as the forest is lightened up, forms an almost unpenetrable jungle. Rhododendrons are very common in this layer and so are climbers like Tripterygium regelii, Vitis, Actinidia, Clematis and many others. Fortunately for the plant collector, the Korean vegeta tion zones occur latitudinally as well as altitudinally and so a great variation of plant species might be collected on just one mountain. Within the limited space of this publication- it is not possible to go into more details of the Korean plant geography and the reader is referred to the papers by the specialists. 25 One character of the Korean vegetation must,however, not be forgotten and that is,that at the present much of the original climax stages of the vegetation have been lost and replaced by secondary stages of a more pioneering nature This is due to overcutting in the past times and to the praxis of shifting cultivation,very common not long ago. The best picture of original Korean vegetation can be obtained in remote mountaineous areas , national parks and temple forests. To what extent the reforestation work now going on will restore the complex patterns of the Korean forest vege tation remains to be seen.lt will,no doubt,take a long time . 26 COLLECTING LOCALITIES A. 38°09 1 N 128°24 ' E, 520-900 m.

Photo M.H. 18.9. 1976 (Neg.nr 19/76:8). 58 dominating species are Betula ermanii, Quercus mongolica, Salix hallasanensis v. longifolia, Magnolia sieboldii, Acer pseudosieboldianum, A. tschonoskii v. rubripes, Sorbus commixta, Lonicera spp. , Weigela subsessilis, Viburnum sargentii, Syringa velutina, Rhododendron mucronulatum and R. schlippenbachii. Rich growth of Tripterygium regelii and Sasa sp. makes the penetration of the vegetation very difficult. Here and there among the shrubs grow stunted trees of Pinus koraiensis. This vegetation type continues all the way up to the at 1594 m. The tree line is lower on the southern side of the mountain than on the other sides. There is more Pinus koraiensis on the southern slopes but on the northern side Quercus mongolica is more common. Down at the foot of the mountain near the Paekyeon-sa temple grows a very old and big pear tree from which fruits were collected (Nr. AD 375). AE. 35°55 1 N 127°46' E, 500 m. North slope of Mt.

Palgong-san where the collections mainly were made around the temple Pudo-am at 800 m. Near the temple stands of Cephalotaxus koreana. On the ridges the forest consists of Pinus densiflora and Quercus mongolica mixed with Betula schmidtii and Sorbus commixta. In the lower layer Rhododendron mucronulatum, R. schlippenbachii , Vaccinium koreanum and Fraxinus sieboldiana are common. On the less exposed slopes where the ground is moister the dominating forest is composed of Carpinus and oak (Carpinus laxiflora, C. cordata and Quercus mongolica). Single trees of Prunus serrulata, Alnus hirsuta, Ilex macropoda and Magnolia sieboldii are mixed with the Carpinus-forest. Aralia elata and Rhododendron schlippenbachii form the dense shrub layer. At the top (1050 m) , a windexposed granite rock, a small growth of Betula chinensis, about 2 meter high, was holding stand above a ground layer of Vaccinium koreanum. In the crevices many herbs were growing, among them Astilbe koreana, Hosta minor and Chrysanthemum zawadskii. AG. 35°19' N 1 28°4 4 1 E, 850-1900 m. Mt. Jiri-san, approached from the southeastern part of the massif. The vegetation around the highest part of the mountain (1915 m) consists of low shrubby forest of Abies koreana, Picea jezoensis, Pinus koraiensis and Betula ermanii. 60 In mixture with these species grow Acer pseudosieboldianum, Weigela subsessilis, Syringa velutina v. palibiniana, Vaccinium koreanum, Rhododendron mucronulatum, R. schlippenbachii, R. tschonoskii, Clematis chiisanensis and Tripterygium regelii. The vegetation changes little along the narrow ridge from the top and down to 1600 m. Scattered trees of Abies koreana - which does not grow below c. 1600 m - under c. 10 meter high Quercus mongolica forest, or in shrubby growths together wigh Betula ermanii, Acer mono, A. pseudosieboldianum. Rhododendron mucronulatum and R. schlippenbachii. In the oak forest there are also Stuartia koreana and many species of Clematis. From a small temple (1400 m) along a sheltered creek down to c. 1250 m grows high forest of Quercus mongolica and Acer mono with Stuartia koreana and Phellodendron amurense. The shrubs of Acer pseudosieboldianum and Rhododendron schlippenbachii are densely covered with climbers such as Tripteryqium, Actinidia spp. , Clematis heracleifolia and others. From 1200 m to 900 m there is a steep ridge exposed south, where the forest has been cut and the coppice in some places has been replanted with Japanese larch. Among the rocks Quercus mongolica. Rhododendron schlippenbachii and Lespedeza spp. are growing. Below 900 m the forest changes to a more warmth-demanding vegetation with Styrax japonica, Stuartia koreana, Lindera obtusiloba, L. erythrocarpa and several species of Quercus. Luxuriant climbers, Smilax spp., Clematis apiifolia, Vitis flexuosa and Actinidia spp., cover the lower vegetation. The ground is very stony and along the small streams at the foot of the mountain Rhododendron yedoense v. poukhanense forms large stands. It seems that this species is very de pendent on moist grounds in order to grow well. 61 AH. 35°17 1 N 1 27°38 ' E, 600-850 m. Mt. Jiri-san, southwestern slopes and a valley at Pyok-so ryong. In the lower parts, fields have been roded and rice grows along the road, whereas beans, Polygonum and other crops climb the steeper fields on the slopes. The forest is a mixture of trees and shrubs: Pinus densi flora, Quercus serrata, Pyrus ussuriensis, Castanea crenata, Phellodendron amurense, Stuartia koreana, Syringa reticula ta, Euonymus sieboldiana, Aralia elata, Rosa multiflora and Rhododendron yedoense v. poukhanense. Around 850 m along a new road going up across mountain, there is a dense shrub- and climbervegetation under an open forest of Zelkowa serrata, Carpinus laxiflora, Quercus mongolica, Q. serrata, Cornus controversa, Stuartia koreana and a few Meliosma myriantha. The shrub layer is dominated by Euonymus oxyphyllus, Lindera obtusiloba, L. erythrocarpa , Styrax japonica, Clerodendron thrichotomanes and everything is woven together by Ampe lopsis brevipendunculata v. citrulloides , Vitis flexuosa, V. amurensis, Tripterygium , Celastrus stephanitifolius and others.

The soil is dense, moist and rich in fine material. On drier parts along the road grows Pinus thunbergii which might be planted. The shrubby forest consists of Quercus mongolica, Carpinus spp. and Sorbus alnifolia. The shrubbery it self is formed of Acer pseudosieboldianum, Styrax japonica, Cornus kousa, Malus asiatica v. wrightii, Photinia glabra, Symplocos sp. , Vaccinium oldhamii - height to 2 m Viburnum furcatum, V. erosum, V. erosum v. taquetii, Eleagnus umbellata, Euonymus alata, Ligustrum ovalifolium, Rosa maximowiczii , lies crenata, Maackia faurei, Rhododendron yedoense v. poukhanensen and Taxus cuspidata. Smilax china, Tripterygium, Euonymus fortunei v. radicans, Akebia quinata and Hydrangea petiolaris grow among the shrubs. In the ground flora there are many thistles, Senecio and Ligularia japonica and even familiar northern plants such as Parnassia can be seen where the ground is moist. Where the forest is dense, Carpinus tschonoskii, C. laxiflora and Quercus mongolica form the high forest with Cornus kousa. Viburnum furcatum, Prunus serrulata, Hydrangea serrata and a few Daphniphyllum and Rhododendron weyrichii in the understorey . BC. 33°22' N 126°30-32' E, 1300-1900 m. Mt. Halla-san. On the south and southwestside of the mountain the Carpinus-Quercus forest continues to about 1250 m. Abies koreana is seen as a mixture from 1200 m. Cornus kousa is very common up to the tree line on the exposed southern side. From the tree line the vegetation changes into pasture-like meadows with a low flora of shrubs and herbs: Stephanandra Ilex crenata, Taxus cuspidata, Cimicifuga taquetii. Aster sp. , Astilbe chinensis v. davidii, Pedicularis sp. and others. 64 Figure 20. Cheju-do, Mt. Halla.

Onwards from 1400 m there is a broad ridge towards the very steep wall which surrounds the old crater (1700-1900 m) This ridge is partly covered with a low shrub vegetation consisting of Rhododendron mucronulatum, R. yedoense v. poukhanense and mixing with Taxus cuspidata, Abies koreana and Juniperus chinensis v. sargentii. Alternating with the lower shrubs are somewhat higher groups of Abies, Sorbus, Betula, Taxus, Malus asiatica, Magnolia sieboldii together with Vaccinium japonicum, Lonicera chrysanta, Hydrangea serrata, Weigela subssessilis , Rosa multiflora and climbers such as Hydrangea petiolaris, Euonymus fortunei v. radicans, Clematis koreana and Tripterygium regelii. On the inside of the old crater there is a meadow around the small lake at the bottom and the walls are covered with a mixture of Abies koreana, Taxus cuspidata, Betula ermanii and Juniperus chinensis v. sargentii. There are also the same species of Rhododendron as on the outside. BD. 33°23' N 126°32-35 1 E, 1950-1000 ra. Mt. Halla-san, eastern side. From the rim of the crater to 1800 m the boulder field is covered with mats of Juniperus, Taxus, Empetrum and Rhododendron. Below 1800 m the forest begins again, and is at first dominated by Abies koreana and Taxus cuspidata. This forest changes down the slope into hardwood forest with the same species as mentioned under BC. From about 1200, m the forest changes into a pure hardwood forest with Betula, Quercus and Sorbus and in addition Prunus serrulata v. spontanea, Cornus kousa, Carpinus spp. , many Euonymus alata, Photinia, Malus asiatica and Vaccinium.

Of these 141 are from coniferous trees, 223 from hardwoods, 343 from shrubs and climbers and 58 from other plants. The material consists mainly of seed samples because due to the field work conditions there were little possibilities for collection and storage of living plants and cuttings and it was not possible to reach air freight or other shipping facilities in short times. A few samples of cuttings survived, however, the strain of prolonged car transport and inadequate storage and were taken home when the members of the expedition returned. The efforts of the expedition were concentrated on trees and shrubs but seeds of herbaceous plants were collected only occasionally. When forest trees of possible value for tree breeding were collected samples were usually taken from single trees and kept separate. These individual collections were noted in the seed list with sublettering a, b, c... Herbarium specimens were taken from most of the collected numbers. This material was compared at Seoul with reference material of the F.R.I, and we tried as far as possible to verify the indentification notes made in the field. The detailed list of the material collected is seen in Appendix 1. The same data have also been published separately in the "Seed List 1976, Seed from S.Korea" by the Forest Research Institute, Forest tree breeding station, 01590 MAISALA, Finland. 71 HANDLING AND DISTRIBUTION OF SEEDS AND PLANTS Seeds were collected in paperbags or nylon-net bags in the field since plastic bags proved to dense and samples in them were frequently taking molds and rot. Samples were not usually opened en route due to the tight scheme of travelling but when returning from the field trip the lots were ventilated and dried at the headquarters in Seoul. Berries and fruits were cleaned from their fleshy organs, washed and dried. During the warm and sometimes humid conditions of transport it could not, however, sometimes be avoided that mold or rot destroyed samples. It seems, that in the conditions of early autumn in Korea a rapid handling of the seed lots, using permanent headquarter staff provided with cleaning and storage facilities would improve the work of a collecting expedition. Sometimes it was necessary to collect seeds that were not quite ripe, because a return to the locality was not possible. In such cases some of the germination power might have been lost and further collectors should study the ripening conditions an possibilities for after-ripening of the seeds of important species such as Magnolia sieboldii. Dry seeds were packed in dried paper bags and cones in nylon net and packed tight in wooden boxes which, when full, were sent home by ships provided with cold stores for the passage through tropical waters. All boxes arrived at Copenhagen in the beginning of December 72 1976 and between the 11. - 14. of this month the seeds were unpacked, checked and distributed to the four participating countries . Seed lots were given permanent seed numbers (the G-numbers of the seed list) and seed register cards were set up for each lot. A seed list was made in the winter of 1976-77 and sent out to 78 institutions in 12 different countries. Of these institutions 39 from 14 countries returned orders for seed and a total of 3 310 lots of material has been distributed by 1978. Due to lack of space and working capacity all samples could not be sown in the same place and the Scandinavian material was therefore divided according to climatological conditions and to particular interests. Some of the material is still in the stage of strajtification since the germination rate for some species was very low at the beginning. When plants have been obtained, the plant material is registered on plant cards for each lot and these cards contain also information about the further distribution of the plants. Inventories and records of germination have been kept in all stations growing the material in the Nordic countries. As mentioned above, herbarium material was also collected. The herbarium plants were as well as possible dried en route and stored at the headquarters until they could be sent home with the seed boxes. The mainherbarium collection has been given to the Botanical Museum, University of Helsinki and the Botanical Museum 73 University of Uppsala where it will be included in the museum's collections and be disposable for scientists interested in the Korean flora. Smaller herbaria are given to the Arboretum HjzSrsholm and the Agricultural High School, As. It is intended that further herbarium specimens will be collected from the material grown, in order to provide for studies about variation within the species. 74 SUGGESTIONS FOR FURTHER ACTIVITIES The conditions in Korea are to a high degree suitable for the evolution of geographical varieties. In our material there is already at the nursery stage indi cations that for instance in the Rhododendron species there are provenances with distinct habits on the different mountains where these species were collected. The same might be the case for many of the other widely distributed trees and shrubs. The material now growing in the nurseries should therefore, whenever possible, be the object of provenance experiments for which the different localizations of the Nordic arboreta provide a great opportunity. Since provenance experiments with ornamental trees and shrubs have hardly been heard of before, schemes for obser vations must be worked out and distributed. On the basis of these observations and results from the experiments a more consistent view of collection areas and plant variation in Korea might be obtained. The observations on which provenances are good for which localities should also be compared with the views of the Korean botanists. This work provides, in the long run, for more detailed instructions for Korean plant collectors, and it might in the future be possible to develop an organization for collection and distribution of seed of known origin. 75 a material for which there, no doubt, is a great need. Minor products form a good part of the trade of Korean forest products and, once a reliable system is established, there seems to be a market also for seeds. One might consider that a permanent committee could be set up for the cooperation between the Nordic countries and the Republic of Korea in these and related fields. 76 BIBLIOGRAPHY Below are listed some books and papers that may be of interest for further reading.
