Forests of the Iberian Peninsula blackberry bushes, blackthorn, hawthorn and other more or less thorny shrubs; this role can also be filled by smaller thorny plants, "los piornales", and clumps of broom. The major forests in this area are beech, oak, birch, and fir. Beech forests ("Fagus sylvatica") are found in the mountain layer of the Iberian Eurosiberian region from 800 to 1500 metres up. The soil is cool, as often chalky as siliceous (rich in silica), and nearly always acidified by rain. The layer is characterised by the beech tree. The beech tree projects a deep shadow, and so its dense foliage usually excludes
Luzula sylvatica least greenish throughout winter. The leaves can also help to differentiate the plant from similar-looking plants in the closely related genus "Juncus", as scattered white hairs can be found along the leaf edges. Its tepals are , with flowers which grow in groups of 3 or 4. From mid-spring to summer, "L. sylvatica " produces flowers in open panicles which are very small, chestnut-brown in colour and can be found in dense and lax clusters. "L. sylvatica" is sometimes stoloniferous. "Luzula sylvatica" is both anemophilous and entomophilous, in that it can be pollinated by either wind or insect. "L. sylvatica"'s
