Impact Type: Deposition of pollutant
Norwegian mugwort (Artemisia norvegica) is a globally rare arctic/alpine plant found on only three mountains in NW Scotland, where it occurs in Racomitrium heath. As a component of this sensitive habitat it is expected to be sensitive to N deposition (Biodiversity Steering Group 1995).
There is no published research on the impact of pollution on this species. Stimulation of growth of cohabiting species would be expected to be detrimental.
