EUNIS habitat classification 2017 > T1-G1 - Alnus cordata forest

Alnus cordata forest

Description (English)

Broadleaved deciduous, non-riparian forests dominated by Alnus cordata, subendemic to Corsica and southern-Italy (Campania, Basilicata and Calabria Regions). The dominant species is a relict from the Tertiary period and is also present in other areas, where it is not considered native. Alnus cordata tends to form forests, either pure or mixed with other deciduous species such as Quercus cerris, Castanea sativa or, at higher altitudes, Fagus sylvatica, frequently on steep slopes and sides of deep valleys.
