釧路湿原国立公園


釧路湿原は、1987年7月に日本の28番目の国立公園になりました。公園の面積は28,788ヘクタールで、ヨシとスゲの茂る広大な湿原、蛇行する川が流れ、湿原の東側には海跡湖があり、丘陵が湿原を取り巻いています。この国立公園は日本最大の湿原で、かつては旧釧路湾の一部でした。海が後退したとき、湾の入り口に砂が堆積し、海から切り離された部分が海跡湖となりました。過去3000年の間に、泥と砂の上に泥炭が堆積し、今日見られる環境が形成されました。湿原には、タンチョウ、シマフクロウ、イトウ、キタサンショウウオなど、多くの希少種が生息しており、湿原周囲の歩道や展望台から観察することができます。公園では、春にはタネツケバナ、夏にはハナショウブ、秋にはタデなどの、様々な植物を観察することができます。冬には、少量の雪が高原に蓄積し、さらに独特で美しい景色を作り出します。


Kushiro Shitsugen National Park


Kushiro Shitsugen (Marsh) became Japan’s 28th national park in July 1987. The park’s boundaries enclose a total area of 28,788 ha. Within its borders are expansive bogs of reeds and sedges, meandering rivers, lagoons, as well as the surrounding hills. The national park is Japan’s largest wetland. This vast plateau was once underwater as a part of Old Kushiro Bay. When the sea retreated, sand built up at the mouth of the bay, and the area was eventually cut off from the sea, becoming a brine lake. Over the past 3,000 years this brine has turned to fresh water, and peat has accumulated atop the mud and sand, creating the environment that exists today. The wetland is home to many rare species, including red-crowned cranes, Blakiston’s fish owls, Sakhalin taimen, and Siberian salamanders. Many of these animals can be spotted from the walkways and observatories located around the marshland. While exploring the park, it is also possible to see many species of plants such as cuckoo flowers in spring, Japanese irises in summer, and water peppers in autumn. In winter, a small amount of snow accumulates on the plateau, creating yet another unique and beautiful landscape.
