Primeval Forest Boasting Distinctive Natural Scenery


The Ogasan Nature Reserve is comprised of dense forests of broadleaf trees and conifers.

The Ogasan Nature Reserve is located in the boundary area between Kim Hyong Jik County in Ryanggang Province and Hwaphyong County in Jagang Province.

Mt Oga includes hundreds of hectares of primeval forest, well over a thousand species of animals and plants, and many rare living monuments.

The growing condition of trees in the mountain, which is in the limelight of the world, is very good, and it is thickly wooded with rare species of tall trees that can only be found in subtropical forests, especially over a thousand-year-old linden, pine-nut tree, fir, spruce and Mongolian oak, and tara vine, rice-paper plant and other creepers which are over 40m long and more than 10cm in diameter are twined round them.

The reserve unfolds unique natural scenery as it is placed in the border between the distribution areas of temperate and boreal plants. Growing there are polar plants like thuja and rhododendron as well as southern temperate plants including Sasamorpha purpurascens and Phyllitis japonica, with such northern temperate plants as pine-nut tree, fir, basswood tree and white birch forming the main part of the flora.

According to botanists, most of the primeval forests in the world are pure forests and it is hard to find such a mixed forest of needle-leaf and broadleaf trees as in Mt Oga, which is on the boundary line between boreal and temperate plant distribution areas.

The reserve is also blessed with such plants of economic value as wild insam (ginseng), forest asiabell, anise and Schizandra chinensis, mushrooms of medicinal value including Fomes japonicus, agaric and Lnonotus obliqus, and many lichens and mosses.

For its green foliage and diverse natural and geographical conditions, it also provides a favourable ecological environment for animals. It is home to many animals and well over a hundred species of birds.

The fact that more than half of animals in residing Korea inhabit the reserve shows the abundance of fauna and flora there.

The Ogasan primeval forest covering an area of 800 hectares was registered as the living monument. And over 1,100-year-old yew, some 700-year-old linden and pine-nut and other trees are in good protection as living monuments.
