Iberian sclerophyllous and semi-deciduous forests

The Iberian sclerophyllous and semi-deciduous forests is a mediterranean forests, woodlands and scrub ecoregion located in the Palearctic biogeographic realm, covering Europe, northern Asia, North Africa, and the northern Middle East, spanning approximately 297,956 km². Classified under the WWF ecoregion code PA1209, this region represents a distinct ecological community shaped by its unique combination of climate, geography, and evolutionary history.

Climate and Vegetation

This ecoregion experiences mild, wet winters and hot, dry summers. The dominant vegetation consists of sclerophyllous shrubs, evergreen oaks, and drought-resistant herbs. These conditions create the foundation for the ecological communities found within the Iberian sclerophyllous and semi-deciduous forests.

Ecological Significance

Mediterranean ecosystems rank among the world's biodiversity hotspots, with exceptionally high rates of plant endemism. Fire is a natural and essential ecological process in these systems. The Iberian sclerophyllous and semi-deciduous forests contributes to the broader biodiversity patterns of the Palearctic realm.

Geographic Distribution

The Iberian sclerophyllous and semi-deciduous forests extends across Portugal and Spain. This geographic range places it within the Palearctic realm, one of the eight major biogeographic divisions of the world.

Notable Species

The Iberian sclerophyllous and semi-deciduous forests supports a range of wildlife, including (Bacidia rosella), (Ramalina lacera), (Parmeliella parvula), (Bactrospora dryina), (Mycoporum antecellens), (Toninia cinereovirens), (Gomphillus calycioides), (Ramalina canariensis), and 42 more species. Among these, 20 species are classified as threatened on the IUCN Red List, underscoring the conservation importance of this ecoregion.

Conservation

Like many mediterranean forests, woodlands and scrub ecosystems, the Iberian sclerophyllous and semi-deciduous forests faces threats from urbanisation, fire regime changes, invasive species, and drought intensification. Conservation efforts in this ecoregion focus on habitat preservation, sustainable land management, and protecting corridors that connect fragmented habitat patches.
