Italian Sclerophyllous And Semi-Deciduous Forests

The ecoregion covers most of the Italian Peninsula and includes both evergreen and deciduous forests.

The ecoregion extends from the southern Po Basin in northern Italy to the southern Apennine Mountains of Basilicata and Calabria. It covers the lowlands of central Italy, including the valleys of the Arno and Tiber rivers, the Tyrrhenian Sea (western) coast of central Italy and Liguria, extending into southeastern France, and central Italy's Adriatic coast, as well as the middle elevations of the Apennines.

The Apennines' higher-elevation montane forests are considered separate ecoregions – the Apennine deciduous montane forests in central Italy and the South Apennine mixed montane forests in southern Italy. The coastal lowlands and foothills of Campania, Calabria, and Apulia in southern Italy are part of the Tyrrhenian-Adriatic sclerophyllous and mixed forests ecoregion.

Rock types are limestone, dolomite, marl, schist-marl, and sandstone.

Cities in the ecoregion include Rome, Florence, Genoa, and Nice.

The forests vary in species composition with elevation and soils.

Lower elevation forests are dominated by sclerophyllous evergreen oaks, including holm oak Quercus ilex, often on limestone-derived soils, and cork oak Quercus suber, often on soils derived from volcanic rocks. They are accompanied by deciduous trees and conifers such as: Quercus pubescens, Fraxinus ornus, Ostrya carpinifolia, Celtis australis, Acer monspessulanum, Carpinus orientalis, Pinus pinaster, Pinus pinea, Pinus halepensis and Crataegus monogyna.

At middle elevations, forests are predominantly deciduous oaks, including Quercus cerris, Quercus pubescens, and Quercus frainetto, with sweet chestnut (Castanea sativa) and Ostrya carpinifolia.

In the highest portions of the Apennines, the sclerophyllous and semi-deciduous forests transition to the Apennine deciduous montane forests and South Apennine mixed montane forests, which are dominated by deciduous European beech (Fagus sylvatica), together with other deciduous broadleaf trees Acer pseudoplatanus, Acer obtusatum, and the strict endemic A. Lobelii, Sorbus aria, Sorbus aucuparia, Sorbus torminalis, Ulmus glabra, Tilia platyphyllos, Populus tremula, Ilex aquifolium and conifers Taxus baccata and Silver fir.

The ecoregion is home to thousands of plant species, with over 2000 on the Gargano Peninsula alone. Endemic species are from 10 to 20% of the total, and occur from sea level up to the high mountains. The ecoregion's orchids are diverse, particularly in the mountains; the Maiella Mountains have 60 known species, and the Gargano Mountains have 56 species.

Much of the ecoregion is still forested. There are areas of old-growth forest in relatively inaccessible mountains, and larger areas of coppice woodlands, many of which are no longer harvested and are regenerating naturally. Grazing and timber harvesting has altered the forest structure and species composition across much of the ecoregion.

Population is concentrated in cities, valleys, and along the coast, and much of the countryside is thinly populated. Many rural areas have been abandoned since World War II as Italy urbanized and industrialized.

A 2017 assessment found that 18,302 km², or 18%, of the ecoregion is in protected areas. Protected areas include Gargano National Park, Alta Murgia National Park, Cinque Terre National Park, Capanne di Marcarolo Natural Park, and Bracciano-Martignano Regional Park.
