Scattered remnants of the original Caledonian pine forest occur in the area, though not on the extreme west coast or islands where such forests did not occur.  Often planted, and self-sown seedlings are frequent but seldom attain maturity.

Leaves (needles), c 3-10 cm long

ID: Leaves glaucous on the underside, due to several bluish-white lines along their length.  Needles in pairs.

Other features: Mature trees have smooth reddish-brown areas of bark on the upper trunk.

Lodgepole Pine (P contorta) is often planted for forestry.  It does not have glaucous leaves and is unlikely to produce self-sown seedlings.

As the leaves are twisted, both sides of them can be seen in this picture, the dark green upper side and the glaucous underside.

  On a close-up view
the glaucous effect
on the underside is
caused by these bluish-
white lines alternating
with dark green.
