A Twist tree bark, in wood around Fraserburgh, Aberdeenshire, Scotland, Spiral growth is beloved by photographers for the beautiful curves to be found in the bark and wood of the trees. Sawmills, on the other hand, are not so pleased to see a spiral-grained log in their yard; the wood is often weaker and spiral-grained boards often twist as they dry. Despite the reduction in the raw strength of the wood itself, spiral growth gives a tree greater flexibility than its straight-grained neighbours, making the tree more resistant to high winds or heavy snow loads. Another possible cause for spiral grain is to better distribute water around the tree. In straight-grained trees, the needles or leaves, though spiral growth is more common in conifers share water, photosynthate, and nutrients with the roots directly below them. If the roots or branches were to be damaged on one side of a straight-grained tree, the corresponding roots and branches would wither. A spiral grain, on the other hand, allows resource sharing all around the tree, distributing water from a single root to branches all around the tree, and sugars made in the leaves on a single branch to all the roots. By distributing water and nutrients evenly, a spiral-grained tree can more easily survive periods of drought or windstorms, as well as the chronic stresses of growing in dry, windy areas.
