An evergreen forest is a forest made up of evergreen trees. They occur across a wide range of climatic zones, and include trees such as conifers and holly in cold climates, eucalyptus , live oak , acacias , magnolia , and banksia in more temperate zones, and rainforest trees in tropical zones.
The Daba Mountains evergreen forests are a Global 200 endangered ecoregion located on the Daba Mountains in China. [1] The forests are part of temperate broadleaf and mixed forests containing both coniferous and broadleaf trees covering a swath of Central China .
The Nihonkai evergreen forests ecoregion (WWF ID: PA0427) covers a thin strip of land on the western coast (facing the Sea of Japan) of the island of Honshu in Japan. It is bounded on the east by the Nihonkai montane deciduous forests ecoregion.
South Korea has 379 species of birds, including 111 are winter visitors and 90 are winter and spring passage migrants. Most of these species either reside or visit the southern evergreen forests, where the winter climate is milder. 207 bird species and subspecies have been recorded on the Jeju, and 54 species on the Ulleungdo Island.
Generally the moister the forest habitat the greater the understory density. Coast mixed evergreen is drier than coast redwood and it is a four-layer forest structure. The conifers are usually emergent as canopy layer and broad-leaf evergreen trees emerge as sub-canopy layer. The shrubs occur as the understory species.
Laurel forests grew near the coast, and oak forests were predominant inland. At higher elevations, the Taiheiyo evergreen forests yielded to the Taiheiyo montane deciduous forests of the interior. [2] The forests include a mix of species with origins in temperate and tropical Asia.
An especially well-preserved example of remaining forest exists on Mount Emei at the western edge of the Sichuan Basin. The original forests are thought to have been made up of subtropical oaks, laurels, and Schima. Much of the remaining Sichuan Basin has been converted to anthropogenic agricultural use in the last 5,000 years. [1]
The forests of the area are under pressure from the increase in rubber and pulp plantations, and commercial agricultural crops in the understory. [6] As of 2012, the region supported 117 threatened species (out of a total of 1,114 species), 28 of which were endemic. [3] Very little pristine forest remains within this ecoregion.
