Frost crack or Southwest canker [1] is a form of tree bark damage sometimes found on thin barked trees, visible as vertical fractures on the southerly facing surfaces of tree trunks. Frost crack is distinct from sun scald and sun crack and physically differs from normal rough-bark characteristics as seen in mature oaks , pines , poplars and ...
When sun scald appears on trees it is most frequently a result of reflected light off the snow during winter months. The damage in this case will appear as sunken or dead bark on the trunk of the tree, then later in the tree's life the bark might fall away revealing dead tissue in the tree's cambium layer.
The entire visible plant may turn completely brown until the spring warmth, or may drop all of its leaves and flowers, leaving the stem and stalk only. Evergreen plants, such as pine trees, withstand frost although all or most growth stops. Frost crack is a bark defect caused by a combination of low temperatures and heat from the winter sun.
Sunscald happens in winter when bark cracks and splits due to temperature fluctuations between cold nights and direct sunlight. It not only damages the tree, but it can make it susceptible to ...

Frost's own children were avid "birch swingers", as demonstrated by a selection from his daughter Lesley's journal: "On the way home, i climbed up a high birch and ...
The trees are often scorched and burnt up, as with the most excessive heat, in consequence of the separation of water from the air, which is therefore very drying. In the great frost in 1683, the trunks of oak, ash, walnut, and other trees, were miserably split and cleft, so that they might be seen through, and the cracks often attended with ...
Among the commercial products made from bark are cork, cinnamon, quinine [48] (from the bark of Cinchona) [49] and aspirin (from the bark of willow trees). The bark of some trees, notably oak (Quercus robur) is a source of tannic acid, which is used in tanning. Bark chips generated as a by-product of lumber production are often used in bark mulch.
