principles of nature conservation, using different levels of protection is associatedwith ecological networks. To allow multiple use of the network - avoidingunnecessary or excessive restrictions - the level of protection will be adapted to localneeds. This will vary from strict protection (restrictions for recreational use, forexample.) to partial limitation for economic uses.The core areas are areas that contain unique landscapes and habitats, withspecial ecological value. Preserving these characteristics contributes to biodiversityprotection. The level of protection of this areas should be most intense, because theyare home to those items that have the greatest need of protection.The corridors are essentially characterized by migration, dispersal, geneticexchange and energy flow. They make the connection between the various coreareas allowing these exchanges, and decreasing isolation and "island" situations.Buffer areas surround a specific interest areas (usually areas with fullprotection) in order to reduce or buffer the negative impact from the outside.Limitations on certain economic or recreational activities in buffer areas preventaffecting the core areas.Ecologival restoration areas may be important for the global design of thentwork or may present a high environmental and ecological potential. We haveshown above that only the least favorable sites, dry and nutrient-poor tend to be leftfor the implementation of conservation projects while the most interesting areas fromecological point of view are generally used for agriculture. Reconstruction supportsthe return to nature of high biodiversity areas with significant landscape value.Design a network may seem simple in theory, but it is a very complex taskbecause often need to combine conflicting interests. Different species do not alwayshave the same needs, and may be required for priority setting and a combination ofgoals.Selection and identification of ecological network components is a complexprocess based on a comprehensive view of natural and human activities. In thisprocess must be collected and analyzed a large amount of data. Tools as maps offorestry, land, biota, water quality, biodiversity monitoring data must be used toprovide the basis for a coherent network. EU CORINE Biodiversity and CORINELand Cover initiatives are very valuable tools for such purposes.97
Stages of an ecological networkThe first step to achieve ecological networks would be to define areas of a certainimportance. This activity depends on the criteria and careful analysis of the data. Atthis stage, one must try to balance the various modes of land use, based onpriorities.Policymakers should first be able to identify landscape elements that define a certaincorridor, and then to understand how individuals and local populations respond to it.The effectiveness of a corridor regarding the mobility of species that occur can not beeasily defined when it includes a wide variety of organisms (large and smallmammals, insects, small birds). The presence of individuals of other species such aspredators that could influence the migration and survival of target species is anotherexample of the complications that arise when it comes to networking.However, once all information is gathered, priorities and criteria defined are definedand analysed can expect to design a network, at least on paper. The next step is avery simple procedure and requires making sure that all items are enjoying a level ofprotection required. This includes defining the exact extension of the area, ensuringthat they are all available for protection (eg. some may be privately owned) and toobtain all necessary local support.VI.3 National and european ecological networkEuropean Ecological Network (EECONET) started to develop at the initiativeof the Netherlands- Institute for European Environmental Policy, which developed theconcept of ecological network in 1991. This concept has expressed the idea of anintegrative and dynamic protection of species and organisms related with theirenvironment and rely on identifying the most significant ecosystems as 'fullyprotected areas'. It also includes protection of 'green corridors', promoting themigration and dispersal of living organisms and, naturale'semnificative developmentareas particularly in terms of functional ecological network and its individualsubsystems (Bennett, 1991).The idea of European ecological network (EECONET) recommends to beincluded and unprotected areas that have not so far been protected by law significantfor EECONET dynamic and also requires the protection of ecological corridors withinthe meaning of the corridors of European importance, national or regional .98
