Mt. Adatara


On the upper portion of the mountain, where the wind is strong, Acer tschonoskii, Enkianthus campanulatus, Hakusan rhododendron, Ilex sugerokii, Aasa kurilensis, and other colonies of shrubs spread, and in the valley-like terrain forests of beech and Japanese oaks stretch to the upper portion. Maries' fir and other subalpine conifers also formed small groves in patches due to the recent volcanic activity and the limited mountain breadth. Meanwhile, in areas where the remnants of the volcanic activity stop, short shrubs, such as crowberries and Alpine azalea, as well as fringed galax, false snowparsley, Japanese knotweed and other volcanic plants can be seen.

[Yukawa Gorge]

Almost entirely covered in Mongolian oak, planted groves of cypress and larch are also mixed in. On the steeply sloped terrain groves of monarch birch, and on the ridges, Japanese white pine groves are generally found. In the undergrowth various types of Rhododendron shrubs are found and on the forest floor, it is mostly a variety of ferns. In the undergrowth near the sheer cliffs varieties of Rhododendron, Enkianthus campanulatus, and Rhododendron degroniamum can be found, and on the forest floor you can see flowers such as Vaccinium hirtum, Blechnum amabile, Ixeris stolonifera, Epilobium cephalostigma, Clinopodium micranthum, and Aster glehnii var. hondoensis.

[Sogodai]

Here, low shrubs of Acer tschonoskii and Sasa kurilensis cover the entire region. In addition, Moliniopsis japonica and Hosta rectifolia can be seen in the wet zone, Japanese silver grass in the slightly drier zone, and Quercus crispula groves on the sloping areas. In the snow field (snow bank created by the seasonal wind) below Mt. Tetsu, Moliniopsis japonica, Veratrum stamineum, and holly ferns can be seen. Rhododendron brachycarpum are also common in the area, which is protected as a natural habitat for Rhododendron brachycarpum, the prefecture's designated natural monument.

[Volcanic desert]

From the north side of the tip of Mt. Adatara to Mt. Tetsu, there is a large amount of barren land due to volcanic activity that once took place there and you can find volcanic vegetation. Heathberry, alpine azalea, and other shrubs are widespread as well as plants such as fringed galax, false snowparsley, Japanese knotweed. Along the slope from Kuroganegoya to Mt. Tetsu, Japanese silver grass, Salix reinii, and heathberry can be found. And in the unplanted area near the Numanotaira crater, wavy Hairgrass, Arcterica nana and other volcanic pioneers are scattered.

[Mt. Minowa and Mt. Kimen]

Stable plant colonies can be seen in areas where volcanic activity died out during relatively ancient times. You can find dense shrubbery, such as dwarf Siberian pine, Rhododendron brachycarpum, Japanese alpine cherry, acer tschonoskii, and rowan. In some places you can find underbrush plants, such as lingonberry, heathberry, fringed galax, coptis trifolia, and other alpine plants. Sasa kurilensis grows densely in the Sasadaira area, as the name suggests.
