Ecoregions Of Japan
Japan is home to nine forest ecoregions, reflecting its climate and geography. The islands that constitute Japan generally have a humid climate, which ranges from warm subtropical in the southern islands to cool temperate on the northern island of Hokkaidō. Ecoregions overview Japan lies at the convergence of three terrestrial biogeographic realm, realms, the Palearctic, Indomalayan realm, Indomalaya, and Oceanian realm, Oceania, and its flora and fauna combine elements from all three. The ecoregions that cover the main islands of Japan, Honshū, Hokkaidō, Kyūshū, and Shikoku, along with the nearby islands, are considered part of the Palearctic realm. The island arcs of southern Japan, the Ryukyu Islands to the southwest and the Ogasawara Islands to the southeast are home to Tropical and subtropical moist broadleaf forests, subtropical moist broadleaf forest ecoregions; the Nansei Islands subtropical evergreen forests ecoregion is part of the Indomalayan realm, while the Ogasawa ...

Lake Biwa
is the largest freshwater lake in Japan. It is located entirely within Shiga Prefecture (west-central Honshu), northeast of the former capital city of Kyoto. Lake Biwa is an ancient lake, over 4 million years old. It is estimated to be the 13th oldest lake in the world. Because of its proximity to the country's historical capital Kyoto, references to Lake Biwa appear frequently in Japanese literature, particularly in poetry and in historical accounts of battles. Name The name ''Biwako'' was established in the Edo period. There are various theories about the origin of the name ''Biwako'', but it is generally believed to be so named because of the resemblance of its shape to that of a stringed instrument called the ''biwa''. Kōsō, a learned monk of Enryaku-ji in the 14th century, gave a clue to the origin of the name ''Biwako'' in his writing: "The lake is the Pure land of the goddess Benzaiten because she lives on Chikubu Island and the shape of the lake is similar to that of ...

Freshwater Ecoregion
An ecoregion (ecological region) is an ecological and geographic area that exists on multiple different levels, defined by type, quality, and quantity of environmental resources. Ecoregions cover relatively large areas of land or water, and contain characteristic, geographically distinct assemblages of natural communities and species. The biodiversity of flora, fauna and ecosystems that characterise an ecoregion tends to be distinct from that of other ecoregions. In theory, biodiversity or conservation ecoregions are relatively large areas of land or water where the probability of encountering different species and communities at any given point remains relatively constant, within an acceptable range of variation (largely undefined at this point). Ecoregions are also known as "ecozones" ("ecological zones"), although that term may also refer to biogeographic realms. Three caveats are appropriate for all bio-geographic mapping approaches. Firstly, no single bio-geographic frame ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Hokkaidō Montane Conifer Forests
The Hokkaido montane conifer forests ecoregion covers the mountainous central regions of Hokkaido Island, the northernmost of Japan's main islands. Forests of spruce and fir thrive in the subalpine, cool climate. On the northeastern edge of the island, the conifer forests extend down to the sea under the influence of the cold Oyashio Current coming down from the north, although logging in recent years has put pressure on these stands. Location and description The mountainous region is surrounded by the lower plains and hills of the Hokkaidō deciduous forests ecoregion. Central to the region is the Daisetsuzan Volcanic Group, the location of Daisetsuzan National Park, the largest national park in Japan. The highest mountain on the island, and in the region, is Asahi-dake with an elevation of . Above the conifer line, alpine conditions support thickets of Stone pine ''( Pinus pumila)'' Climate The climate of the ecoregion is '' Humid continental climate, warm summer'' ( ...

Temperate Coniferous Forests
Temperate coniferous forest is a terrestrial ecoregion, terrestrial biome defined by the World Wide Fund for Nature. Temperate coniferous forests are found predominantly in areas with warm summers and cool winters, and vary in their kinds of plant life. In some, needleleaf trees dominate, while others are home primarily to Broad-leaved tree, broadleaf evergreen trees or a mix of both tree types. A separate habitat type, the tropical coniferous forests, occurs in more tropical climates. Temperate coniferous forests are common in the coastal areas of regions that have mild winters and heavy rainfall, or inland in drier climates or montane areas. Many species of trees inhabit these forests including pine, cedrus, cedar, fir, and redwood. The understory also contains a wide variety of herbaceous and shrub species. Temperate coniferous forests sustain the highest levels of biomass in any terrestrial ecosystem and are notable for trees of massive proportions in temperate rainforest reg ...
