Wildlife of South Korea

Article 2 of the Wildlife Conservation and Management Act discusses endangered wild animals in South Korea.[4][5] There are 246 endangered animals in South Korea,[6] with numerous species in need of urgent conservation measures.[7] Endangered wild animals in South Korea include:

• Leopard cat is the country's only wild cat. It lives foremost in mountainous regions.[8]
• Red-crowned crane occurs along Imjin River.[9][10]
• Golden eagle ranges across the country.[11]
• Siberian musk deer occurs at Mokpo in South Jeolla Province.[12]
• Hodgson's bat
• Asian black bear
• Mongolian wolf occurs in North Gyeongsang Province, Gangwon Province and North Chungcheong Province.[13]

Harmful wild animals are wild animals which damage property or endanger people.[14]

For example, harmful wild animals in South Korea include

• Sparrow, magpie, jay, crow, brown-eared bulbul which damage fruit crops in groups over a long period of time.[15]
• Pigeon, pheasant, elk, mole, red squirrel, some kinds of rat and duck which have high population densities, and therefore damage agriculture, forests and fisheries.
• Magpie which damage power facilities such as utility poles.[16]
• Pigeon which damage residences with their feces and feathers.[17]
• Wild boar roam the mountain sides, but have been coming down to the city centers in search of food.[18] These animals are big, strong, and fast and can potentially be fatal to humans.[19]
• Asian giant hornet when they are grouped together they can destroy an entire hive of bumble bees. they usually live in large trees and they have been known to attack people who accidentally run into their nest.[20]

Korea can be divided largely into three biozones by distribution of plants. The groups are warm-temperate forest, temperate forest and subalpine forest. Considering regional character of Ulleungdo and Jejudo, Korea can be divided into five regions. Evergreen broad-leaved trees grow in warm-temperate forest. Warm-temperate forest in Korea includes the southern coastal region, Jeju Island and several islands of the southern sea which are under 35°N. Some of the species here include Quercus myrsinaefolia, Quercus acuta, Quercus salicina, Daphniphyllum macropodum, Castanopsis cuspidata, Ligustrum foliosum nakai, Machilus thunbergii. South Korea is dominated by temperate forest which takes 85% of its territory. Land between Korean Demilitarized Zone and the northern part of 35°N belongs to this. Common species in temperate forest are Carpinus laxiflora, Carpinus tschonoskii and Quercus mongolica. A subalpine forest exists in the Kaema Plateau in North Korea or south-central's higher mountains. Picea jezoensis, Pinus pumila, Abies nephrolepis, Larix gmelinii and Abies holophylla can be found there.[22]

Ulleungdo: A sort of trees which reseed with Mt. Seonginbong as a center based on approximately 600 m altitude. Altitudes below 600 m have wild plants in the Southern province that are magnolia, Euonymus japonicus, Camellia japonica, Hedera rhombea, Ardisia japonica, Vitex rotundifolia and others. An altitude of 600 m or above has Fagus crenata and Sorbus commixta.[22] Jejudo can be divided into coast vegetation and mountain vegetation. Coast vegetation consists of Sinomenium acutum, Machilus thunbergii, Daphniphyllum macropodum, Camellia japonica, Vitex rotundifolia, Centella asiatica. Reynoutria elliptica, Hydrangea serrata, Eleutherococcus senticosus, Aconitum napiforme, Schisandra repanda and others.[22]

The southern part of temperate forest is contained in a region 37°N at the west coast, 38°N at the east coast and inner land's temperate forest that is a southern part of 36.5°. There are common bamboo, Acer palmatum, Carpinus laxiflora and others. In Jirisan mountain, there are Hemerocallis fulva, Picea jezoensis, Cornus officinalis, Rhododendron mucronulatum, Abies koreana, Eleutherococcus senticosus, Aconitum chiisanense, Angelica gigas and others. In Mt. Deogyusan, there are Aconitum uchiyamai, Sorbus commixta, Acanthopanax sessiliflorus, Cimicifuga simplex and others. In the coast district, there are Camellia japonica, Euonymus japonicus, Daphniphyllum macropodum, Camellia sinensis and others.[22]

The central part of temperate forest contains 39°N at the west coast, 40°N at the east coast and inner land's temperate forest that include between a southern part of 38° boundary line (38th parallel north) and Northern Limit Line of south temperate forest. There are Quercus dentatomongolica, Acer pictum subsp. mono, Betula costata, Zanthoxylum planispinum and others. In Seoraksan Mountain, there are Hemerocallis dumortieri, Ampelopsis brevipedunculata, Rhododendron brachycarpum, Rhododendron fauriae and others. In Odaesan Mountain, there are Astilbe chinensis, Berberis koreana, lily of the valley and others. In Chiaksan Mountain, there are Codonopsis lanceolata, Lactuca indica, Hieracium umbellatum, Aconitum and others. In Mt.Taebaeksan, there are Juniperus chinensis, Taxus cuspidata, Juniperus rigida, Pinus densiflora, Viola diamantica Nakai, Trientalis europaea, Arisaema erubescens and others. In Cheonmasan Mountain, there are Juniperus chinensis, Taxus cuspidata, Juniperus rigida, Draba nemorosa L., Eranthis stellata Maxim, Hepatica asiatica Nakai, Adonis amurensis, Heloniopsis koreana and others. In Mt.Sobaeksan, there are Iris rossii, Hylomecon and others. In Woraksan Mountain, there are Actinidia arguta, Thymus quinquecostatus, Rubus coreanus and others. In Mt.Songnisan, there are Leonurus japonicus, Angelica gigas and others. In Juwangsan mountain, there are Staphylea pinnata, Jeffersonia, Fraxinus rhynchophylla, Rhododendron schlippenbachii and others. In the islands of the west coast, there are Machilus thunbergii, Camellia japonica, Epimedium koreanum, Scopolia japonica, Berberis koreana, Valeriana fauriei, Cornus officinalis, Schisandra chinensis and others.[22]

The northern part of the temperate forest is in between a north limit of central temperate forest and boundary line(38th parallel north). There are Betula platyphylla, Pinus koraiensis, Acer komarovii, Ligularia fischeri, Rhododendron aureum, Epimedium koreanum, rhubarb, Viola mandshurica, Lithospermum erythrorhizon and others.[22]

In South Korea, boreal forests do not exist in the lowlands. However, subalpine coniferous forest is found in highland or mountainous district in South Korea. Part of Hallasan, part of Seoraksan, fir forest of Jirisan and Gotjawal Forest in Jeju Province are the subalpine forests in South Korea. At an altitude of 1200 m–1500 m in Hallasan, there is a coniferous forest which consists of pine, juniper, a Korean fir. Fruticeta is formed in 1500 m–1700 m and the alpine zone spread out above 1850 m. South-facing slopes have more mild weather than north-facing slopes. Therefore, its height extends a little more on the south side.[23][24][25][26]

Endangered wild plants are divided into first grade and second grade.[27]

Rhododendron aureum

Neofinetia falcata

Sundew

• The DMZ and the CCZ are bordered by land mines which leave the areas untouched by humans. This untouched habitat is significant for persevering the East Asia flyway system of migratory birds from Russia to Australia. The white-naped crane, and the red-crowned crane populations are most affected.[56]
• This area is also home to many other endangered species of birds and mammals, including the Asiatic black bear.[58] The Asiatic black bear is considered; threatened on the endangered species list due to people harvesting the stomach bile and gallbladders using it for Chinese herbology.[59]
• The importance of wildlife conservation and undisturbed habitats is recognized by many, including the South Korean Ministry of Environment,[57] which wishes to keep the DMZ untouched by people in order to safeguard biodiversity.[58]
