Impact Type: Deposition of pollutant
Calluna vulgaris is a species which is often dominant on acidic heathland soils and so would be expected to be tolerant of acid deposition. No work has been published as to the effects of acid deposition perse on Calluna. The most likely effect will be a reduction in Phosphorous availability on the acid, low nutrient soils inhabited by Calluna which could help ameliorate negative effects of eutrophication.
Most studies on the effects of air pollution on Calluna have concentrated on nitrogen deposition and the effects of eutrophication. Uren et al (1997) reports that (NH4)2 SO4 additions reduced frost hardiness.
