Apparent trajectories of change to mire communities due to nitrogen deposition, in terms of the UK National Vegetation Classification \citep[NVC, ][]{Rodwell1998}. (a) Community change to plots in the NH\({}_{3}\) treatment. Dashed lines indicate weaker evidence of community transition. (b) Apparent trajectories of changes to mire NVC communities due to NH\({}_{4}^{+}\) and NO\({}_{3}^{-}\) treatments.
