Hoar frost

As fragrance break in are forestry tree damage referred to by frost caused. Trees that regularly suffer damage from hoarfrost are called scent breakers .

etymology

The term fragrance break is based on the original, Old High German meaning of the word fragrance as fog or frozen haze , from which fragrance developed as a term for hoar frost.

Damage characteristics

Coniferous woods such as spruce and pine are most frequently affected by fragrance breaks , as these, due to their needling, which is also present in winter, offer the hoarfrost a large target area; but also deciduous trees such as oak , beech and birch are considered to be susceptible to damage from fragrance breakage. The damage usually occurs in the form of broken branches and as a nest or peak break and is very similar to the damage caused by snow breakage . Fragrance breakage often occurs together with snow and ice breakage.

In the red beech farms of the 19th century, old trees were left at the edges of the forest to protect the younger trees, so that they, among other things, act as scent breakers to intercept the hoarfrost and thus protect the growth from damage.
