Effects and implications

  • Nitrogen deposition provides a fertilization effect on acid grasslands which are generally N limited.
  • N deposition favours graminoids (grasses) at the expense of forbs and lower plants, especially where sites are surrounded by farmland.
  • Nitrophilous grasses tend to shade out slower growing species.
  • Nitrophilous grasses increase the amount of litter which falls on and shades out under-storey bryophytes (Berendse et al 1987).
