This tree is a cross between the native Rowan and S. pseudofennica. [21] In 2002 it was estimated that 81.6% of Scotland's woodland was coniferous, with much of this consisting of plantations of non-native conifers. The most commonly planted tree species was Sitka spruce, which covered
a species that colonised these islands during the retreat of ice at the end of the last ice age; a species that was present in these islands when the English Channel was created and the land bridge between Britain and continental Europe was flooded; a species that has colonised without human assistance; in some cases this is uncertain.
The flora of Scotland is an assemblage of native plant species including over 1,600 vascular plants, more than 1,500 lichens and nearly 1,000 bryophytes.The total number of vascular species is low by world standards but lichens and bryophytes are abundant and the latter form a population of global importance.
Conifers account for around one half (51%) of the UK woodland area, although this proportion varies from around one quarter (26%) in England to around three quarters (74%) in Scotland. [8] Britain's native tree flora comprises 32 species, of which 29 are broadleaves. The UK's industry and populace uses at least 50 million tonnes of timber a year.
The tree is again a cross between the native rowan and whitebeam, the discovery being made following work by Scottish Natural Heritage (SNH), Dougarie Estate and Royal Botanic Garden Edinburgh. Research into the genetics of whitebeam trees had shown that the population was much more diverse than previously thought and that the Arran whitebeams ...
