Classification   The protection range of nature  Length   About 83,306,160m2  Date of listings   10, July, 1973  Location   A part of Seohwa-myon Inje-gun Gangwon-do, A part of Sudong-myon and Ganseong-eup in Gosung-gun  Proprietor   Inje-gun, Gosung-gun  Administrator   Inje-gun, Gosung-gun  General Description  The Hyangrobong, Geonbong Mountain natural Preservation Area is located through Koseong-kun, and Inje-kunin Kangwon province. This area from Chiljeolbong through Hyangrobong and geonbong mountain and up to the demilitarized zone (DMZ) is holding the characteristic of the temperate zone forest of Korean central districts. In the Gojin-dong valley at Geonbong mountain, the main species of trees is Quercus mongolia, and the royal azalea, Aster scaber, Lespedeza maximowiczii, and Sasa borealis are composing forest; pine tree, fir tree, Sasa borealis, and Cornus controversa are also growing.  Hyangrobong area has a colony of Sasa borealisfrom 500m above the sea level; another colony of Sasa borealis and Magnolia sieboldii from 700m. At the near the peak, Magnolia sieboldii and Magnolia sieboldii are entangled together, since big trees were eliminated because of military tactics; and rare plants, such as Magnolia sieboldii and Magnolia sieboldii are growing across the ridge.  In the valleys of Hyangrobong and Geonbong mountain, some fish which need to be protected, such as Magnolia sieboldii, Oncorhynchus masou var. ishikawai, Geumkangbochi, Chinese minnow, Moroco oxycephalus, and the thin striped shinner/stripe gudgeon, Pungtungia herziare inhabiting; 24 kinds of birds near Geonbong mountain and 11 kinds in Hyangrobong are ascertained. Among the 24 kinds of Mammalia ascertained, otter, musk deer, mountain goat, bear, flying squirrel need special protection. The Hyangrobong, geonbong mountain natural preservation area preserves the natural forest which was not touched by human and is the most representative region where the animals and plants are well preserved, is designated as natural treasure and thus protected.  Details  This is a watershed area which connect Hyangrobong (1296m) and Geonbong mountain, running through east and west, and is part of the Taebaek Mountains. On both side of the mountains, the north river which runs through the valley goes to the East Sea and in the west, water gathers to the Nam river which is the boundary between north and south. The fantastic rocks are composed of gneiss, which has weak resistance to whethering, there are not many exposed cave-ins, and a plain near the valley cannot be developed.  Even though there are not many big trees in the ridge area because of military tactics, in the valley over the both ridges preserve the typical forest aspect of the deciduous broadleaf trees in the temperate zones, since it was not touched by human. Especially the forest aspect of the Gojin-dong valley, from the Geonbong temple to Geonbong mountain, where the natural forest aspect is well preserved, is the subject of the precious studies in the future.  Quercus mongolica are the most common and well-growing trees in this area; therefore, the plant group which is growing with Quercus mongolixa can be noticeable. The most common plant group in this area is the royal azalea and the mountain cherry under the Quercus mongolica trees; then Quercus mongolica and Lespedeza maximowiczii, Quercus mongolixa and Quercus mongolixa group, Quercus mongolica and pine trees or Quercus mongolicaunder the pine trees, or the pure group of Quercus mongolica can be seen. The group of fir tree is seen partially, and in some area, Weigela subsessilis and the royal azalea are growing together. The steep side from Geonbongryung to the Gojin-dong valley where the upper trees were eliminated, the magnolia trees became bigger, and Kalopanax pictus, ash tress, pine trees and are well growing under the Quercus mongolica, oriental oak, pine tress, and Kalopanax pictus trees. In the gorge where the Quercus mongolica trees are diminishing and the wild-walnut trees, Carpinus laxiflora, and Carpinus laxifloraare more appearing, the water of the brook runs through the gorge.  In the Jechookgol where the west of the Hyangrobong, a colony of Carpinus laxiflora trees and magnolia trees were formed near 700-800m in altitude; a colony of Carpinus laxiflora and Carpinus laxiflora are developed in 500-600m in altitude; Cornus walteri, wild-walnut trees, Cornus walteri, and ash trees are growing in the lower part.  Going near to the peak, Cornus walteri and Cornus walteri are entangled together, since the tall trees were eliminated. In the crack of the rocks, Cornus walteri, Sangeowool, Cornus walteri, Valeriana fauriei, Valeriana fauriei, Valeriana fauriei, Valeriana fauriei, Valeriana fauriei, and Valeriana faurieiare growing; a big colony of Sapium japonicum is developed aroundthe ridge 750m to 900m in altitude. So far, Celtis choseniana, Sapium japonicum, Abies nephrolepis, Thuja koraiensis, and Alnus fruticosa var. mandshurica, together with the colony of Hanabusaya asiatica belong to the kinds which need to be protected.
