Europe's wildlife under threat from nitrogen
Posted on 14 April 2011
An international study published today warns that nitrogen pollution, resulting from industry and agriculture, is putting wildlife in Europe at risk. More than 60 per cent of the EU’s most important wildlife sites receive aerial nitrogen pollution inputs above sustainable levels.
There is evidence of impacts
on semi-natural grasslands, heathlands and forests across Europe. This threat
is set to continue unless there is further action on emissions of polluting
nitrogen gases.
The study calls for a unified
methodology of assessing the impact of aerial nitrogen pollution across Europe
to help in efforts to safeguard significant conservation sites.
Dr Kevin Hicks, of the SEI at
the University of York, said: “While the nitrogen impacts on plant species are
relatively well understood its effects on other wildlife, such as butterflies,
and the consequent implications for biodiversity are not so clear.”
A team of scientists,
conservation and environmental managers and policy makers from across Europe,
co-ordinated by the Stockholm Environment Institute at the University of York,
reviewed evidence from across Europe. The study confirmed nitrogen deposition as a major threat to
biodiversity in the Natura 2000 network established under the Community’s
Habitats Directive to safeguard important habitats and species.

Nitrogen Deposition and Natura 2000 is published today at the Nitrogen and Global Change conference
in Edinburgh. It follows the publication earlier this week of the first
European Nitrogen Assessment (ENA).
Dr Mark Sutton, from the UK's Centre for Ecology & Hydrology and the lead editor of the European Nitrogen Assessment, said: "This new volume takes the essential next steps, building on the conclusions of the European Nitrogen Assessment: It highlights the great challenges faced in managing the threat of nitrogen deposition to Europe's flagship conservation network.
“Concerted action is now needed to link European conservation, air pollution and agricultural policies to ensure that the scientifically established damage thresholds are not exceeded."

- The
study results from an international workshop on ‘Natura 2000 and Nitrogen
Deposition’, held in Brussels in May 2009, to review new evidence of
nitrogen impacts, develop assessment best practice, and recommend options
for future policy development.
- The Stockholm Environment Institute at the University of York
coordinated the study in collaboration with the Centre for Ecology &
Hydrology (CEH), the Joint Nature Conservation Committee (JNCC) and the
Countryside Council for Wales (CCW) under the COST European
intergovernmental network for cooperation in research.
- The
workshop was attended by 73 scientists, conservation practitioners and
policy makers from 13 countries: Austria, Belgium, Denmark, Finland,
France, Germany, Greece, Ireland, Portugal, Spain, Sweden, Netherlands and
the UK. Delegates included representatives from the European Commission DG
Environment, and Government departments from EU member states.
- The main sources are emissions
of oxides of nitrogen from the burning of fossil fuels by industry and vehicles
and releases of ammonia from agriculture, particularly intensive livestock
production.
- The
Habitats Directive, the cornerstone of Europe’s nature conservation
policy, requires EU Member States to maintain or restore rare and
threatened habitats and species to ensure their long-term survival. The
Directive the Natura 2000 network of wildlife sites and requires strict protection
measures and a precautionary approach to permitting “plans or projects” that
are likely to have a significant effect on a site.
- Stockholm Environment
Institute is an independent international research institute. The Institute has
established a reputation for rigorous and objective scientific analysis in the
field of environment and development. SEI’s goal is to bring about change for
sustainable development by bridging science and policy. Further information at www.sei-international.org
