The forests that cover the mountains and valleys of the Baekdu Mountain Range - from Mt. Baekdu, in the north, to Mt. Jiri, in the southwest, forming the spine of the Korean Peninsula - and the southern coast and islands of the peninsula - including Jeju Island - feature a wide variety of conifers and broadleaf trees. Much of these forests are protected in mountain and marine national forests, such as in Hallyeohaesang National Park, which encompasses 150.14 km2 of mountainous forests spread out over 69 uninhabited islands and 30 inhabited islands in Korea's South Sea that provide a home to 1,142 plant species, including major species such as red pine, black pine, common camellia, serrata oak, and cork oak, as well as rare species such as nadopungnan (sedirea japonica), daeheongnan (cymbidium nipponicum) and the Korean winter hazel. Major animals species, such as otters, small-eared cats, and badgers also call Hallyeohaesang National Park home, and overall there are 25 mammal species, 115 bird species, 16 reptile species, 1,566 insect species, and 24 freshwater fish species found among the forested, mountains islands.
