Iberian sage-leaved willow scrub

Small or medium-sized willow scrub of meso-Mediterranean and, locally, supra-Mediterranean, zones of central Iberia (Castellano-Leonese sectors, Extremadura), characterized by the presence of the Iberian endemic [Salix salvifolia] and [Salix x secalliana], together with [Salix atrocinerea], [Salix x matritensis], [Salix neotricha], [Salix purpurea ssp. lambertiana], [Salix triandra ssp. discolor]; they line, mostly on siliceous sandy soils, small oligotrophic rivers with strong seasonal amplitude, or form behind the taller curtain of the [Populo nigrae-Salicetum neotrichae] along large water courses of argilous base-rich soils.
