Ahabitat model of each species was prepared by mapping the species occurrenceafter both the referent information and the data of field surveys against the hydromorphologicalparameters of freshwater bodies on the Bulgarian territory. Twentyseven species of the Bulgarian freshwater ichthyofauna, are protected within theNatura 2000 National Network, including 6 local fish species accepted relevant toclose species enlisted in the Habitat Directive but absent in Bulgarianichthyofauna. Fish populations are protected in 142 sites of the Natura 2000National Network. The portion of potential habitat area of different fish speciescovered by the proposed Natura 2000 National Network to their total area all overthe country varies from 15% to 83%. Only Leuciscus souffia and Umbra krameripresent an exception of that number since their habitats may be adopted as totallyprotected. The significance of the potential habitats for conservation of the nationalpopulations of target fish species depends mainly on both environmentalparameters and human pressure. The area of the Natura 2000 sites along theDanube River is considered quite insufficient to guarantee the adequate protectionof the habitats of local and diadromous target fish species and some extension ofthe protected areas is proposed and to assure the Natura 2000 Network coherence.14:45-15:00ЧЕРВЕН СПИСЪК НА ПТИЦИТЕ В БЪЛГАРИЯТ.М.

В статията е представен новияЧервен списък, който съдържа 155 вида птици: Regionally Extinct (REX) – 10;Critically Endangered (CR) – 32; Endangered (EN) – 45; Vulnerable (VU) – 53;67
