Forest migration northward. Though "Fagus" and "Picea" populations did not expand directionally, they have grown in the Scandinavian range. The movement of "Picea" species in the past 1000 years has shown a strong connection to climate change through a model comparison. In the more recent past, there has been documentation of elevation shifts in distribution of many core forest tree species of Catalonia. The populations of two tree species (European Beech, "Fagus sylvatica"; and Holm Oak, "Quercus ilex") were evaluated in their dynamics over elevations through time. Generally, Holm Oak reside lower on mountain slopes than does European Beech. In the past

The cultivar ‘Marginata’ has gained the Royal Horticultural Society’s Award of Garden Merit. Luzula sylvatica Luzula sylvatica, commonly known as greater wood-rush or great wood-rush, is a perennial flowering plant in the rush family Juncaceae. With regards to the etymology of the binomial, "Luzula" could come from the Italian "lucciola" ("to shine, sparkle") or the Latin "luzulae" or "luxulae", from "lux" ("light"), inspired by the way the
