The analysis presented in Report 447 represents the first part of a large study of nitrogen impacts on vegetation.

In this second part of the project, the results of the new analysis, together with other sources of independent evidence, are interpreted in respect of implications for “conservation commitments”.

The most recent assessments of the effects of air pollution on semi-natural habitats in the UK, using critical loads, show that a substantial area is at risk from either acidification or eutrophication. The conservation agencies’ monitoring of SSSI condition is based on Common Standard Monitoring (CSM) guidance http://www.jncc.gov.uk/page-2219. CSM provides a basic framework to ensure consistent monitoring in the UK.

Ozone is globally the most important gaseous pollutant causing effects on vegetation. While a number of reviews have evaluated the evidence of impacts of ozone on semi-natural ecosystems, none of these has specifically focussed on the priorities of nature conservation agencies.
 
Hall, J., Bealey, B. & Wadsworth, R.
The Conservation Agencies are required to assess the condition of each designated site, and are instituting a Common Standards Monitoring scheme to determine the condition of each site at regular intervals. Air pollution could have a negative impact on these sites and hence needs to be investigated by the Agencies.

This report describes a two-part field study, which applied bioindicator methods in parallel. The use of biomonitoring methods is an approach which could provide an early warning of sites at risk from N deposition.

This project was jointly funded by the Countryside Council for Wales, English Nature, Joint Nature Conservation Committee and the Centre for Ecology and Hydrology

Over the past two decades, concern over the effects of atmospheric nitrogen deposition on terrestrial ecosystems has led to the instigation of a number of field manipulation studies. These were reviewed in an earlier report, commissioned by English Nature. This review updates and revises that earlier report, based on a comprehensive review of all relevant published literature since 1997.
 
Farmer, A
Outlines the effects of air pollution on the natural environment of Britain, the regulatory framework for its control, and how such impacts can be reduced. Includes a summary of the air pollution problem; critical loads; recovery and restoration (dealing especially with lichen communities and with air pollution on the south Pennine peatlands); air pollution and Environmental Impact Assessment; and sustainable development and air quality.
 
Maitland, P.S, Newson M.D & Best. G.A
Considers the effects of each stage of the forestry cycle - ground preparation, tree planting through to canopy closure - in relation to their physical, chemical and biological impacts on freshwater habitats.
