This report includes results obtained from the SELNAT research project, conducted between February 2006 and January 2008, under the auspices of the Belgian Science Policy. The principal subject of this project is the implementation of Natura 2000. The Natura 2000 network of protected areas, made up of sites designated under the Community Birds (BD) and Habitats Directives (HD), is a key pillar of action for the conservation of biodiversity (European Commission, 2008). It is central to achieve the commitment to reverse the decline of biodiversity in the European Union by the year 2010 made at the European Council meeting in Gothenburg in June 2001. It aims at sustainable conservation of habitats and species of community importance, taking into account (i) economic, social and cultural requirements and (ii) regional and local circumstances. Central to the Directives is the creation of a Europe-wide ecological network of protected sites – the Natura 2000 Network – which is destined to conserve over a thousand rare, threatened and endemic species and some 220 Natural habitats listed in their annexes. Around 24,000 sites have been included in the Network so far. (European Commission, 2008) Now that the network set-up is nearing completion, there is a need to increase the focus on the active management of the sites so as to ensure long-term conservation and the achievement of the economic and social objectives of the network (CEE, 2004.) This in turn also raises the question of finding the appropriate management strategy, instruments and sufficient financing (at all levels). The principal question for Member States is how to manage Natura 2000 sites to reach the (juridical fixed) ecological targets in the most cost-efficient way, taking into account economic and social objectives and constraints. Ecologists and nature organisations often start from an techno-ecocentric paradigm: ‘How to conserve and manage species and habitats?’, in order to tackle the question mentioned above. The paradigm starts from the opinion that ‘diversity of species and habitats’ is important as such (while this is believed to be important for several reasons). This approach has been criticised lately for being based on a too narrow set of values. It has not provided enough opportunities for combining nature conservation with other forms of land use such as agriculture, forestry or tourism. In several countries this led to difficulties as regards the co-operation of local stakeholders (Jongman & Kristiansen, 1998). On the other hand, the current biodiversity crisis is a direct result of the way in which society has chosen to interact with its Natural environment. If the causes of the problem are social, it stands to reason that the policies striving to solve the problem will need to be based on a solid understanding of social structures and processes, if they are to have any effect. In this research project we tried to study the management of Natura 2000 sites from a ‘sustainability’ paradigm, instead of from the ecocentric paradigm. The central research question is therefore formulated as ‘How to manage Natura 2000 properly, to contribute to a (local) sustainable society?’ With this research we hope to give decision-makers new insights on the economic, social, and environmental consequences of Natura 2000 management and to guide them in the development of more adequate and sustainable policies for the management of Natura 2000-sites. In the first chapter the general objectives and approach of this project are described. The second chapter gives an overview of some of the current bottlenecks for nature conservation and Natura 2000. The results of the research on the elaboration of strategies for Natura 2000 sites are summarizes in chapter tree. Conclusions and recommendations are presented in the last chapter. More information on the research is documented in the different appendixes. During the research, we benefited from contacts with many persons, and more especially in the scope of a Users’ Committee. Besides the representatives of the Belgian Science Policy, we would like to thank all members of the Users’ Committee, among which those who supported us and/or participated in one or several of the meetings, [less ▲]

In Belgium, the delineation of Special Protection Areas (SPA) and Special Areas of Conservation (SAC) has been done. At present many questions arise concerning the management of these areas. The multiple use of the space generates conflicts of interest. The SELNAT-project aims to answer the question “How to make Natura 2000 work properly?”, taking into account socio-economic, legal and ecological management aspects. This project aims to achieve more insight in a sustainable management of Natura 2000 sites. In a first part of the study, the legal framework, the ecological status and the socio-economic frame have been described. The main legal, economic, social and ecological bottlenecks for the Natura 2000 network implementation in Belgium have been highlighted. In a next phase, guidelines for the elaboration of a ‘good management plan’ for the Natura 2000 network will be developed at the local scale taking into account the principles of the Ecosystem approach.. The fundamental question in this part is which instruments are needed at what time in the implementation process to reach the ecological targets taking into account economic, legal and social considerations. In a first step we evaluated the feasibility and effectiveness of these instruments by means of a literature review and a survey among experts of the field. In a second step we’ll try to develop a management plan for two case study areas, a Flemish site and a Walloon site. A the end of the project, recommendations for policy makers about the improvement of these instruments will be formulated. [less ▲]

The Brabant sablo-limoneux region is located in the south and near Brussels, in the phytogeographic district of Brabant (Atlantic domain). This region is characterized by a high diversity of local ecological conditions due to the alternance of important tertiary sand outcrops and quaternary silty layers. The agro-sylvo-pastoral activities, which were practiced on these sandy and sand-silty soils for centuries, caused the evolution of the climactic forest into semi-natural habitats such as dry heathland, sandy grassland and grassheath. The evolution of the heathland distribution from 1770 to the present has been studied on the scale of the Dyle hydrographic subbasin (43.000 ha). It is characterized by an important regression of this habitat in the study area (from 1460 ha in 1770 to 72 ha in 2006), mainly due to Pinus sylvestris orchards, and more recently, to urbanisation caused by the proximity of Brussels. A generalized ageing and an environmental closing characterize the evolution of heathland physiognomy since the middle of the 20th century. The phytosociology of heathlands, sandy grasslands and grassheaths has been characterized and 19 groups of vegetation have been differentiated. Among the 393 listed higher plant species, more than 30 are of great conservation interest in the regional context. A hierarchisation of restoration priorities has been established on the scale of the studied hydrographic subbasin and management measures have been proposed. [less ▲]

Au sein du district phytogéographique brabançon, le Brabant sablo-limoneux est caractérisé par une grande diversité de conditions stationnelles. Les versants sont occupés par d’importants affleurements de sables du tertiaire, alternant avec des placages limoneux du quaternaire. Les activités agro-sylvo-pastorales, pratiquées sur ces sols sableux et sablo-limoneux durant des siècles, ont fait évoluer la forêt climacique vers des milieux semi-naturels tels que la lande à bruyère, les pelouses sur sable et la nardaie. L’évolution de la distribution des landes à bruyère de 1770 à nos jours a été étudiée. Celle-ci est marquée par une forte régression de cet habitat dans la zone étudiée (de 1460 ha en 1770 à 72 ha en 2006), due principalement aux plantations de pin sylvestre et à l’urbanisation. L’évolution de la physionomie des landes depuis le milieu du 20ème siècle est caractérisée par un vieillissement généralisé et une fermeture du milieu. Les landes à bruyère et pelouses sur sable ont été caractérisées du point de vue phytosociologique et 19 groupements de végétation ont été différenciés. Parmi les 393 espèces végétales supérieures recensées, plus de 30 présentent un grand intérêt de conservation. Une hiérarchisation des priorités de restauration des landes a été établie à l’échelle du bassin hydrographique étudié et des propositions de gestion ont été avancées. Le cas de la Grande Bruyère de Rixensart a été examiné en particulier. Sur ce site de 7 hectares, on peut parcourir plusieurs habitats semi-naturels de grand intérêt patrimonial tels que lande à bruyère, pelouses sur sable, nardaie, prairie à molinie et végétations de bas-marais des suintements de pente. Ce site est un des derniers témoins des pratiques agro-sylvo-pastorales traditionnelles en Brabant. La végétation actuelle et son évolution depuis 1940 ont été caractérisées et une ébauche de plan de gestion a été élaborée. [less ▲]
