# Wildlife of South Korea

"none" is preferred when the title is sufficiently descriptive; see [[WP:SDNONE]] The wildlife of South Korea includes 8,271 plant species, 18,117 animal species and 3,528 species of fungi and others. 30,000 species are known to inhabit South Korea, among an estimated 100,000+ in all.

## Animalia

South Korea has complex terrain and is surrounded by water on three sides. Therefore, South Korea has multiple climate zones and high precipitation, leading to diverse wildlife.
18,117 animal species include 1,528 species of vertebrates, 13,025 species of insects, and 3,564 species of other invertebrates.

### Endangered wildlife

Article 2 of the Wildlife Conservation and Management Act discusses endangered wild animals. Among the 246 endangered species are many in need of urgent conservation measures. Endangered animals include:
* Leopard cat – the only wild cat. It lives primarily in mountainous regions.
* Red-crowned crane – lives along the Imjin River.
* Golden eagle – ranges across the country.
* Siberian musk deer – lives in Mokpo in South Jeolla Province.
* Hodgson's bat
* Asian black bear
* Mongolian wolf – lives in North Gyeongsang Province, Gangwon Province and North Chungcheong Province.

### Harmful wild animals

Harmful wild animals are wild animals that damage property or endanger people.
Harmful wild animals include:
* Sparrow, magpie, jay, crow, and brown-eared bulbul, which damage fruit crops.
* Pigeon, pheasant, elk, mole, red squirrel, and some kinds of rat and duck damage agriculture, forests and fisheries given their high population densities.
* Magpie damages power facilities such as utility poles.
* Pigeon damages residences with their feces and feathers.
* Wild boars roam the mountainsides, but have begun coming to cities centers in search of food. These big, strong, and fast animals can potentially be fatal to humans.
* Asian giant hornets, in swarms, can destroy an entire hive of bumblebees. They usually live in large trees and have been known to attack people who accidentally run into their nests.

## Flora

South Korea hosts 8,271 species of plants, consisting of 4,662 vascular species and 3,609 non-vascular species. Wild plants include species native to Korea such as Pentactina. Ecosystems are unstable because of land development. 67 km$^2$ of forest disappear each year, accounting for 0.1% of South Korean forests.

### Distribution

Korea can be divided into three biozones by plant distribution: warm-temperate forest, temperate forest and subalpine forest. Evergreen broad-leaved trees grow in warm-temperate forests. Warm-temperate forests include the southern coastal region, Jeju Island and several islands of the southern sea which are below 35°N.

#### Warm-temperate forest

Species include Quercus myrsinaefolia, Quercus acuta, Quercus salicina, Daphniphyllum macropodum, Castanopsis cuspidata, Ligustrum foliosum nakai, Machilus thunbergii.
Ulleungdo: A sort of tree that reseeds with Mt. Seonginbong as a center at approximately 600 m altitude. Altitudes below 600 m have wild plants in the Southern province such as magnolia, Euonymus japonicus, Camellia japonica, Hedera rhombea, Ardisia japonica, Vitex rotundifolia and others. Above 600 m Fagus crenata and Sorbus commixta can be found.
Jejudo can be divided into coast and mountain. 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.

#### Temperate forest

Temperate forests dominate South Korea, occupying 85% of its territory, including land between the Korean Demilitarized Zone and the northern part of 35°N. Common species are Carpinus laxiflora, Carpinus tschonoskii and Quercus mongolica.

#### Subalpine forest

South Korea lowlands have no boreal forests. However subalpine coniferous forest is found in highland or mountainous districts. Part of Hallasan, part of Seoraksan, fir forest of Jirisan and Gotjawal Forest in Jeju Province are the subalpine forests. At 1200 m–1500 m altitude in Hallasan, a coniferous forest consists of pine, juniper, and 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.

### Endangered plants

Endangered plants are divided into first and second grades. Species are selected by the Environment Minister after a consultation with the Minister of Central Administration.
First grade endangered wild plants species have populations significantly reduced by natural causes or artificial factors. First grade endangered wild plants include:
* Malus komarovii (이노리나무): This plant is also found in China. It reaches 5m in height. It grows deep in the mountain.

## Demilitarized Zone

The Demilitarized Zone (DMZ) is the unmanned strip of land that separates North and South Korea. Since the Armistice that ended combat in 1953, its ecosystem has reverted to its natural state due to the absence of human activity. The DMZ and Civilian Control Zone (CCZ) (a buffer to the DMZ) support many rivers and abundant diverse ecosystems hosting plant, mammal, fish and bird species, many of which are globally endangered.
Over 5,000 species of plants and animals have been identified as living in the DMZ, including many on the endangered species list. These include: Siberian musk deer, white-naped crane, red-crowned crane, Asiatic black bear, cinereous vulture and the long-tailed goral.

### Preserving biodiversity

DMZ and the CCZ are bordered by land mines that prevent human activities. It is part of the East Asia flyway system of birds migrating from Russia to Australia. The white-naped crane and red-crowned crane populations are most affected.
This area is home to many other endangered animal species, including the Asian black bear, which is rated threatened on the endangered species list due to people harvesting their stomach bile and using it for Chinese herbology.
The South Korean Ministry of Environment works to keep the DMZ untouched by people to safeguard biodiversity.

## Controversies

The Han River ecosystem is endangered because the water flow changed due to water blocking construction at Ilsan Bridge. Deposition of materials in the river caused environmental damage. The Korean Association for the Protection of Wild Birds pushed to remove the structure, which possibly destroyed the natural ecology and caused the bank to overflow.

## Media

The Nakdong River Basin Environmental Office set up an unmanned camera and successfully captured images of wildlife. Wild animals are shown moving around the alpine wetlands and displayed actions such as hunting and territory marking. Martens were rated endangered as apex predators. This footage is the first to document local wildlife in real time. In addition, it offers scientists and government officials the opportunity to address preservation of the alpine climate.
