Aims of the ICP Vegetation

Ozone

  • To conduct coordinated experiments to determine the effects of ozone pollution on crops and (semi-)natural vegetation.
  • To develop computer models to quantify and interpret the influence of climatic conditions and environmental stresses on the responses of plants to ozone, and to use these models to establish critical levels for the effects of ozone on vegetation.
  • To develop maps showing where vegetation is at risk from ozone pollution within the UNECE region, including areas where critical levels are exceeded (in collaboration with EMEP/MSC-West).
  • To collate and review information on the impacts of ozone on crop yield (quantity and quality), including assessment of economic losses and consequences for food security.
  • To collate and review information on the sensitivity of plant communities to ozone and consequences for plant biodiversity.
  • To collate and review information on the effects of ozone on vegetation and carbon sequestration in a changing climate.
  • To consider evidence for the modifying effects of nitrogen deposition on the impacts of ozone on (semi-)natural vegetation.

Heavy metals and nitrogen

  • To collate and review monitoring data on heavy metal and nitrogen concentrations in mosses.
  • To investigate the relationship between modelled atmospheric deposition of heavy metals and nitrogen and their concentration in mosses (in collaboration with EMEP/MSC-West and EMEP/ MSC-East respectively).
  • To link the moss database with other databases.
  • To facilitate knowledge transfer on the impacts of nitrogen on vegetation within the Convention.
