Project Abstract

Critical loads form the basis of the effects-based approach used to guide policy on reducing the environmental impacts of transboundary air pollutants, such as sulphur dioxide and nitrogen oxides. The concept underpins the protocols of the Convention on Long Range Transport of Air Pollution (LTRAP) and the National Emissions Ceiling (NEC) directive, which has supported significant reductions in sulphur emissions. However, there is growing concern that chronic elevated nitrogen deposition is leading to changes in ecosystem biodiversity. The proposed research will develop capacity in assessing the impacts of nitrogen deposition through coupled dynamic soil-vegetation models, specifically in response to data calls under the Convention on LRTAP. The research will build on existing plant releve data (collected by the NPWS) for native woodlands, grasslands and upland ecosystems in protected habitats to support data calls. In addition, the research will maintain and update existing Irish critical loads data to accommodate updates in land cover information and methodologies. The vegetation modelling research will be strongly supported and directed by a collaboration with national and international experts.
