Information and communication on the designation and management of Natura2000 sites. Main Report 4: A Proposal for a Natura2000 partner award scheme

Following the selection of Special Protection Areas (SPA) and Sites of Community Importance (SCI) according to the Birds and the Habitats Directives, most European Member States are now in process of formally designating SPAs and SCIs as Special Areas of Conservation (SAC) or Natura2000 sites. These protected areas collectively form the European Union’s Natura2000 network. Member States are also selecting and implementing adequate management approaches and instruments to maintain and restore the favourable conservation status of protected species and habitat types and to prevent damage to the integrity of the sites. Both actions follow Articles 6.1 and 6.2 of the Habitats Directive. To help the Member States, the European Commission wishes to improve the knowledge and exchange of information and good practice both on the designation process of SPAs and SACs and on the establishment of conservation measures and instruments for these areas. Furthermore, the Commission wants to stress the importance of the sites and their management by involving a wider group of stakeholders in the development of so-called integrated management, in accordance with Article 2 of the Habitats Directive. The project ‘PREPARATORY ACTIONS- Lot 2: Information and communication on the designation and management of sites’ (tender ENV.B.2/SER/2007/0076) is intended to help the Commission to achieve these objectives. This is a proposal to the European Commission (EC) for a new European award scheme recognising ‘Natura2000 Partner’ and ‘Natura2000 Partner of the Year’. Our brief was to “elaborate a proposal for a system for rewarding persons, organizations or institutions that have a particular merit in the management of and the communication on Natura2000 sites.” The brief further stipulated the need for an award that would select ‘Natura2000 Partners’ on an annual basis. From these, a selection would be made, enabling the EC to confer the title of ‘Natura2000 Partner of the Year’. Our proposal allows for Member States (MSs) to award this latter title, with an additional title of ‘European Natura2000 Partner of the Year’ being made annually by the EC

Evolution and spatial variability of heavy metals in mussels (<i>Mytilus edulis</i> L.) in the Scheldt estuary (1996-2002)

This paper presents data on the heavy metal contamination of the soft tissues of marine mussels along the Scheldt Estuary. The study considered both arms of the Scheldt estuary, i.e. the relatively polluted Western Scheldt (WS) and the now marine tidal bay of the Eastern Scheldt (ES). The two systems present an ideal opportunity to investigate, in a field situation, the role of physico-chemical and pollution gradients on metal accumulation in mussels. In the WS, depending on the metal, tissues concentrations decreased by 2 - 6 times from Hansweert (the landward limit for mussels) to Westkapelle on the North Sea coast. Similar decreases were also observed in the ES. With a few exceptions (i.e. Cd, Cu), there were no clear differences in tissue metal concentrations between WS and ES. The study also showed strong positive correlations between tissue metal concentrations and distance from the sea in both systems for most metals. Similar trends were observed for both WS and ES indicating that salinity and metal gradients are not entirely responsible for increasing metal tissue levels towards the inland. Additionally, the influence of the constructed storm surge barrier was evident as heavy metal levels in mussels at sites around the barrier were considered elevated. Furthermore, there were only modest decreases in metal concentrations in mussel tissues between 1996 to 2002, further indication that even in the cleaner ES, efforts to reduce the impact of environmental metal pollution take time to give results

Information and communication on the designation and management of Natura2000 sites. Main Report 2: Organizing the management in 27 EU Member States

Following the selection of Special Protection Areas (SPA) and Sites of Community Importance (SCI) according to the Birds and the Habitats Directives, most European Member States are now in process of formally designating SPAs and SCIs as Special Areas of Conservation (SAC) or Natura2000 sites. These protected areas collectively form the European Union’s Natura2000 network. Member States are also selecting and implementing adequate management approaches and instruments to maintain and restore the favourable conservation status of protected species and habitat types and to prevent damage to the integrity of the sites. Both actions follow Articles 6.1 and 6.2 of the Habitats Directive. To help the Member States, the European Commission wishes to improve the knowledge and exchange of information and good practice both on the designation process of SPAs and SACs and on the establishment of conservation measures and instruments for these areas. Furthermore, the Commission wants to stress the importance of the sites and their management by involving a wider group of stakeholders in the development of so-called integrated management, in accordance with Article 2 of the Habitats Directive. The project ‘PREPARATORY ACTIONS- Lot 2: Information and communication on the designation and management of sites’ (tender ENV.B.2/SER/2007/0076) is intended to help the Commission to achieve these objectives.

Information and communication on the designation and management of Natura2000 sites. Main Report 3: Towards Integrated Management

Following the selection of Special Protection Areas (SPA) and Sites of Community Importance (SCI) according to the Birds and the Habitats Directives, most European Member States are now in process of formally designating SPAs and SCIs as Special Areas of Conservation (SAC) or Natura2000 sites. These protected areas collectively form the European Union’s Natura2000 network. Member States are also selecting and implementing adequate management approaches and instruments to maintain and restore the favourable conservation status of protected species and habitat types and to prevent damage to the integrity of the sites. Both actions follow Articles 6.1 and 6.2 of the Habitats Directive.

The project ‘PREPARATORY ACTIONS- Lot 2: Information and communication on the designation and management of sites’ (tender ENV.B.2/SER/2007/0076) is intended to help the Commission to achieve these objectives. In this report we will elaborate on the concept of integrated management as an option for managing the sites. In the first part the meaning of integrated management will be explored. In a second part we give some examples of management approaches that we think illustrate best the concept of integrated management and its potential to achieve the Natura2000 goals

Differences in metal sequestration between zebra mussels from clean and polluted field locations

Organisms are able to detoxify accumulated metals by, e.g. binding them to metallothionein (MT) and/or sequestering them in metal-rich granules (MRG). The different factors involved in determining the capacity or efficiency with which metals are detoxified are not yet known.In this work we studied how the sub-cellular distribution pattern of cadmium, copper and zinc in whole tissue of zebra mussels from clean and polluted surface waters is influenced by the total accumulated metal concentration and by its physiological condition. Additionally we measured the metallothionein concentration in the mussel tissue. Metal concentration increased gradually in the metal-sensitive and detoxified sub-cellular fractions with increasing whole tissue concentrations. However, metal concentrations in the sensitive fractions did not increase to the same extent as metal concentrations in whole tissues. In more polluted mussels the contribution of MRG and MT became more important. Nevertheless, metal detoxification was not sufficient to prevent metal binding to heat-sensitive low molecular weight proteins (HDP fraction). Finally we found an indication that metal detoxification was influenced by the condition of the zebra mussels. MT content could be explained for up to 83% by variations in Zn concentration and physiological condition of the mussels

Effect of hydrogen ions and inorganic complexing on the uptake of copper by the brine shrimp <i>Artemia franciscana</i>

The effect of hydrogen ions and inorganic complexing on copper uptake in the brine shrimp Artemia franciscana has been studied in chemically defined saltwater solutions. Uptake increases with decreasing hydrogen ion concentration and decreases with increasing carbonate complexation. A simple non-linear model that combines the effect of hydrogen ions on the transport of the metal across the solution-body interface and the effect of hydrogen ions and complexation on the speciation of the metal provided a close functional description of the observed variation in copper uptake by brine shrimp
