Résumé :
|
In Slovakia, 33 diurnal and 12 nocturnal raptor species have been recorded so far. Of these, 18 diurnal raptor species and 10 owl species also breed in the country. Raptor monitoring has a long tradition in Slovakia; however, owl monitoring takes place mostly only at the local or regional level. For some species, specifically Imperial Eagle Aquila heliaca, Saker Falcon Falco cherrug, Golden Eagle A. chrysaetos, Red-footed Falcon F. vespertinus and Red Kite Milvus milvus, the entire breeding populations have been monitored in the long term. The most comprehensive raptor monitoring has been covered by the Raptor Protection of Slovakia (RPS), the NGO specialized exclusively in raptors through its network of working groups for particular species. The Slovak Ornithological Society (SOS/BirdLife Slovakia) is mostly involved in monitoring of common raptors and wintering population of the White-tailed Eagle Haliaeetus albicilla. Monitoring is mostly implemented with the ultimate objective of conserving the targeted species. Therefore, the most endangered raptor species at the international and national levels are the key monitored species. On-line databases became popular for storing monitoring data; recently, Aves-Symfony database operated by SOS, RPS and the Institute of Zoology has been developed. Well established network of professionals and volunteers present the major strength of monitoring for raptors in Slovakia. Unfortunately, not all raptor species are adequately covered by monitoring. Access to monitoring data is constrained by unwillingness of some experts to share data in common databases. Another problem is lack of capabilities to evaluate data at the scientific level. Modern monitoring methods, such as remote monitoring with radio or satellite tracking, are applied only rarely due to financial constraints. Monitoring activities do not sufficiently influence decision making.
