Non-stoichiometry and optical spectra of Nd(III) substituted PbTiO3

The non-stoichiometry of the perovskite (ABO3)-type phase in the system PbO---TiO2---Nd2O3 has been studied. Monophasic compounds of composition Pb1−αxNdxTiO3+x(1.5−α) with x 0.21 and 0.09 α 1.5 were prepared. The ferroelectric Curie temperature (Tc) shows a decrease of 18.5 K/at% Nd with increasing value of x. Tc shows an increase of 3.5 K/mol % PbO with decreasing value of α (increasing content of PbO). The observed effect of α on optical spectra can be interpreted by assuming that Nd(III) ions partly occupy B sites in compounds with α < 1.5

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. This report presents a full description of the results of the project regarding the management of sites

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. 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. 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

Towards an ecological network for the Carpathians

The Carpathian Biodiversity Information System (CBIS) and the proposal for an ecological network for the eastern part of the Carpathians are the two main outcomes of the project funded by the BBI Matra program of the Dutch government. This brochure presents information on how the CBIS was designed, and how the data stored can be retrieved and used. It also clarifies how the CBIS data were used to design the ecological network and, last but not least, it offers recommendations for the use of the proposed ecological network in supporting sustainable developmentin the Carpathians. Due to funding restrictions, the project focused on three east Carpathian countries: Romania, Serbia and Ukraine, which together host the largest area of the Carpathians (Fig. 2). Geographically, the Eastern Carpathians also include parts of the Carpathians located in Poland and Slovakia. Data collection in the Western Carpathians (Czech Republic, Poland, Slovakia and Hungary) will be completed by 2010 and is funded by a parallel project

Natuurgebieden in Europa: bescherming en financiering

In dit werkdocument is informatie verzameld over de bescherming van Europese natuurgebieden (Natura 2000-gebieden en overige beschermde gebieden) en over enkele Europese fondsen, die voor gebiedsbescherming worden gebruikt. Deze informatie is verzameld om inzicht te krijgen in de mate waarin de gebieden beschermd zijn tegen ongewenste veranderingen in landgebruik. Door bestaande indelingen voor gebiedsbescherming (Natura 2000 en IUCN) te combineren met de informatie over de Europese financiële middelen voor deze gebieden wordt een nieuwe indeling van beschermde gebieden gemaakt. Deze indeling zou, na nadere toetsing, gebruikt kunnen worden in modellen als EUruralis ten behoeve van scenario-ontwikkeling op Europees en NUTS 2-niveau

Urgent bedreigde typische soorten en vegetatietypen van Natura 2000-habitattypen

Dit rapport is de weerslag van een onderzoek naar de urgent bedreigde en potentieel urgent bedreigde typische soorten en de urgent bedreigde en potentieel urgent bedreigde vegetatietypen van de habitattypen van de Natura 2000-gebieden. In totaal zijn 67 typische soorten als Urgent Bedreigd gecategoriseerd; nog eens 26 soorten zijn gecategoriseerd als Potentieel Urgent Bedreigd. Voor de vegetatietypen geldt dat er 15 (sub)associaties Urgent bedreigd zijn. Op een bijbehorende cdrom wordt voor al deze soorten en vegetaties de huidige verspreiding gegeven, of herstel binnen of buiten Natura 2000 zou moeten plaatsvinden, wat de knelpunten hierbij zijn en waar de beste herstellocaties gelegen zijn
