The Scots Pine is an evergreen member of the Pinaceae  family.  Although a native tree, the only true native trees are in the Caledonian forests in the highlands of Scotland, it now forms naturally regenerating woods over most of the British Isles where planted.

According to pollen records it has been present at different times in England, and may have been re-introduced after being extinct for several thousand years.

The trees characteristic features are the blue-green paired needles, reddish-orange trunk and limbs in the upper regions of the crown.

As with all Pinaceae, Scots Pine is monoecious, the male flowers form in dense clusters at the base of new shoots, female flowers are small green cones which mature over three seasons resulting in cones of different ages on the same branch.

Scots Pine has over 170 phytophagous insects and other invertebrates associated with it. Foliage feeding larva of both the Pine Looper moth - Bupalus piniaria and the Pine Beauty moth Panolis flammea are considered pests on commercial plantations.
