Impact Type: Deposition of pollutant
Recent changes in the breeding distribution of Dotterel in Britain may be related to deterioration in feeding and breeding habitat due to overgrazing by sheep and possibly acidification (Galbraith et al. 1993). The effect of acid rain thinning the egg shells is not substantiated by field evidence (Pyatt et al. 1998), but there is no field research to support this. The quantitative scale of effects in Britain is therefore highly uncertain.
Consequences of acid deposition are considered relatively small by comparison with loss of feeding grounds through change in management practices.
