Daba Mountains evergreen forests

The Daba Mountains evergreen forests is a temperate broadleaf and mixed forests ecoregion located in the Palearctic biogeographic realm, covering Europe, northern Asia, North Africa, and the northern Middle East, spanning approximately 168,170 km². Classified under the WWF ecoregion code PA0417, this region represents a distinct ecological community shaped by its unique combination of climate, geography, and evolutionary history.

Climate and Vegetation

This ecoregion experiences four distinct seasons with moderate to high precipitation distributed year-round. The dominant vegetation consists of a mix of deciduous and evergreen broadleaf trees such as oaks, beeches, and maples. These conditions create the foundation for the ecological communities found within the Daba Mountains evergreen forests.

Ecological Significance

These forests experience dramatic seasonal shifts that drive migration, hibernation, and phenological cycles. The rich leaf litter supports diverse decomposer communities and fungi. The Daba Mountains evergreen forests contributes to the broader biodiversity patterns of the Palearctic realm.

Geographic Distribution

The Daba Mountains evergreen forests extends entirely within China. This geographic range places it within the Palearctic realm, one of the eight major biogeographic divisions of the world.

Notable Species

The Daba Mountains evergreen forests supports a range of wildlife, including Alfalfa (Medicago sativa), Alfalfa Weevil (Hypera postica), Alsike Clover (Trifolium hybridum), American Black Nightshade (Solanum americanum), American carpet grass (Axonopus compressus), Anil de pasto (Indigofera suffruticosa), Annual Wall-rocket (Diplotaxis muralis), Arabic Gumtree (Vachellia nilotica), and 42 more species.
