Title:

Air-borne Transport of De-icing Salt and Damage to Pine and Spruce Trees in a Roadside Environment

Abstract:

The roadside environment comprises a complex combination of stress factors influencing the growth conditions of roadside trees. The exposure of de-icing salt is only one stress that contributes to the damage. In field investigations, damage to vegetation is shown to have a road-related gradient. On a individual-tree scale, the damage is most pronounced towards the road, but on a twig scale, the damage of conifers outside the splash-zone suggests a factor aggravating the symptoms of de-icing salt damage. In this report, the patterns of damage are discussed in relation to the extent of de-icing salt exposure and other stress factors. The thesis also suggests some topics of future research
