tailieunhanh - Targeted Monitoring of Air Pollution and Climate Change Impacts on Biodiversity

Soil communities are important aspects of biodiversity and they are involved in many important ecosystem processes, particularly nutrient cycling. Soil chemistry is neither an aspect of biodiversity nor one of the primary causes of change addressed by this project. Nevertheless, understanding mechanisms of change and correctly attributing effects to causes are central to the project, making it necessary to understand the soil chemistry at sites. For example, a change in the proportion of acidophilic species in a plant community may be attributed to changing pH of rainfall. However it is possible that. | Final report to Department for Environment Food and Rural Affairs Countryside Council for Wales and English Nature CR0322 Targeted Monitoring of Air Pollution and Climate Change Impacts on Biodiversity .

Presented to steering committee 8 March 06 Version 1a. Additional material on birds and remote sensing implementation plan. Additional text on soils from Sal Burgess included and some formatting problems resolved. Sent to project team and expert group 24 March Not sent to Steering Group as they had already been circulated with additional material separately _ Version 2. Complete revision of text to reduce length and change emphasis to the presentation of proposals for the new network rather than reporting on work carried out change made in response to request from Defra . Remove recommendation for soil phosphorus monitoring in view of need to reduce costs and lack of a generally accepted method. Add dry deposition of sulphate and sulphur dioxide and total S deposition to list of measurements recommended for future review. Summary of results of power calculations added as Appendix 3.
