In South Korea, boreal forest doesn't 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 Jejudo are the subalpine forests in South Korea. At an altitude of 1200 m-1500 m in Hallasan Mountain, 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.
