Balkan temperate rainforests : ウィキペディア英語版 | Balkan temperate rainforests
Balkan temperate rainforests are a small portion of the southeastern Alps and Balkan region contain relatively low elevation (< 1600 m ASL) temperate rainforest flora and fauna. Annual rainfall is in excess of 1600 mm,〔http://www.eea.europa.eu/data-and-maps/figures/average-annual-precipitation〕 supporting a variety of lichens, tree species, and animal species. These forests, comprising approximately 580,000 hectares,〔Temperate and Boreal Rainforests of the World. Ed. DellaSala. Chapter 6. Temperate and Boreal Relict of Europe.〕〔http://www.arcgis.com/home/item.html?id=55fb21937fe7422eb5d59d4e44e22ba5〕 contain a variety of remnant plant and animal species associated with rainforest ecosystems and not found throughout the larger ecoregion recognized by the WWF, the Balkan mixed forest type. == Stand Dynamics ==
As with temperate rainforests elsewhere, fire has relatively less of an influence compared to many other forest types, such as the subalpine of the Western US or the boreal forests. Instead, wind and insects are more important. Small scale gap dynamics are common, as rainfall and storms combine to cause substantial uprooting of individual and small groups of trees. Widespread windstorms occur with some regularity (e.g. less time between events than the lifespan of dominant trees〔Nagal, Levanic, and Diaci. 2007. A dendrochronological reconstruction of disturbance in an old-growth Fagus-Abies forest in Slovenia.〕) and cause extensive gap formation, although not complete mortality over large areas. It is difficult to determine large scale disturbance dynamics, however, due to the few areas that have not been extensively modified by humans.
