Définition EUR 28

Mountain pine (Pinus uncinata) forests, usually open and with a very developed shrubby understory, of the subalpine and montane levels; on limestone, gypsum or siliceous substrate in a cool or thermophile situation depending on the region. Sometimes mixed with Pinus sylvestris, more rarely with Larix-Pinus cembra.
Two major types: 42.41 - mountain pine forests of the western outer Alps, the Jura and Pyrenean ubacs, developed on siliceous or decalcified soils of the subalpine level with a predominately ericaceous undergrowth comprising Rhododendron ferrugineum (Rhododendro-Vaccinion p.); 42.42 - xerocline mountain pine forests of the inner Alps, of the western outer Alps and the Jura, and of Pyrenean adrets, accompanied by a shrubby undergrowth in which Rhododendron ferrugineum is absent or rare (Junipero-Pinion p., Erico-Pinion p.)
