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 division Pinophyta consists of just one class, Pinopsida, which includes both living and fossil taxa. Subdivision of the living conifers into two or more orders has been proposed from time to time.
An endemic species is a plant only native to a certain area. Outside this area, unless spread naturally it is considered non-native, usually as a result of cultivation. Britain and Ireland have few endemic trees, most being micro-species of Whitebeam .
Pinidae (Pinophyta, [18] [28] conifers 70, 600) The term Pinophyta has also been used to include all conifers, extinct and extant, with Pinales representing all the extant conifers. [29] Christenhusz and colleagues extended the system of Chase and Reveal [19] to provide a revised classification of gymnosperms in 2011, based on the above four ...
