Three species of Bush-crickets (Orthoptera) of conservation value or poorly known were found in the Eurasian Eagle Owl food in southeastern Bulgaria. Their localities are new country records and two of them cover Natura 2000 SCI zones. The repeated predation on Bradyporus macrogaster in UTM square MG99 confirms the potential of this area for a new Natura 2000 site.

Abstract The effectiveness and efficiency of the Natura 2000 network for the Eurasian Eagle-owl conservation in SE Bulgaria was assessed by comparing data collected during a long-term study on number of breeding pairs and fledglings before and after network establishment. The Natura 2000 network and non-protected areas showed similar values of the calculated indices according to the number of occupied localities. However, the pairs in Natura 2000 sites bred significantly less fledglings after the creation of the network than the pairs in non-protected ones. The Special Protection Areas (SPA) system created specifically for the preservation of birds has the lowest efficiency in respect to Eurasian Eagle-owl protection. Proposals were made after ‘gap analysis’ for real protection and optimization of the protected-area network to increase the stability of the Eurasian Eagle-owl population in the changing environment.

The small-sized gametophytes and sporophytes of the green shield-moss Buxbaumia viridis (Moug.) Brid. make it difficult to study. However, in Europe, there has been increasing interest in this species in the past few years, mostly as a result of the implementation of the Natura 2000 network. In Poland, B. viridis has only been reported in isolated studies that have been limited in terms of area and the number of participating workers. One of the Polish regions where B. viridis was recently recorded is the Bieszczady Mountains, but there have been no large-scale surveys of that region to date. The objective of the current work was to describe the B. viridis population in the Bieszczady Mountains in terms of its spatial distribution and abundance, investigate its selected microhabitat preferences, and evaluate the conservation status of this moss species within the Natura 2000 site Bieszczady PLC180001. The studied region encompassed 93,490.44 ha, including 69,056.23 ha of managed forests and 24,434.21 ha of forests belonging to the Bieszczady National Park. A preliminary survey was conducted in the Cisna Forest District (forest area of 19,555.82 ha) on 15–17 November 2017, while the main survey was performed in selected forest subcompartments of four forest districts—Baligród, Komańcza, Lutowiska, and Stuposiany—as well as the Bieszczady National Park from 5 to 16 November 2018. The field work consisted of searching for B. viridis sporophytes and setae and recording selected population and locality characteristics. The study led to the discovery of 353 new B. viridis localities in 202 study areas, with 9197 diploid individuals (sporophytes or setae only) growing in 545 microhabitats. The number of B. viridis localities discovered in the Bieszczady Mountains during 17 days of survey in 2017 and 2018 was two times higher than the combined number of localities previously found in Poland over more than 150 years (159 localities). Additionally, the number of sporophytes and setae identified was two times greater than their overall number in previous records. In addition, this study provides information about selected microhabitat preferences and the conservation status of this moss in the Bieszczady Natura 2000 site.

Abstract Pedersen, S. A., Fock, H., Krause, J., Pusch, C., Sell, A. L., Böttcher, U., Rogers, S. I., Sköld, M., Skov, H., Podolska, M., Piet, G. J., and Rice, J. C. 2009. Natura 2000 sites and fisheries in German offshore waters.–ICES Journal of Marine Science, 66: 155–169. The principal objective of sites selected as part of Natura 2000 is to achieve or maintain a favourable conservation status of habitats and species named in the EU Birds and Habitats directives. In the German exclusive economic zone, the habitat types protected by this legislation are sandbanks and reefs; protected species include marine mammals, seabirds, and specific migratory fish species. The ICES project Environmentally Sound Fishery Management in Protected Areas (EMPAS) aims to answer two questions: (i) To what extent do specific fishing activities significantly threaten attainment of the conservation objectives of the Natura 2000 sites? (ii) What management measures would reduce these conflicts and how effective would they be at helping to ensure the favourable condition of these sites? Assessments of fishing impacts on Natura 2000 sites require basic data on the conservation status of individual habitats and species, as well as data for fine-scale distributions of ongoing fishing activities. This paper describes and discusses the process used by the EMPAS project in developing fishery-management plans for each Natura 2000 site in German offshore waters.

The inventory of birds was conducted in the years 2005-2010 on the Vistula River section between Dęblin (388 km of the river) and Podwierzbie (435 km of the river). The study area includes a southern section of the European Ecological Natura 2000 Site in Poland PLB140004 „Middle Vistula River Valley” (IBA, PL083). In most areas the Vistula flows here within unregulated or relatively little modified riverbed, having features of natural, lowland, braided river. Sandy islands and braid bars within the main channel, steep banks, and old riparian afforestation create the unique breeding habitats of the Vistula River Valley. Especially the river channel habitats provide suitable breeding sites for many rare bird species, constituting some of them the key-breeding sites. There are, however, fragments of several kilometers, where people transformed the Vistula River in a more visible way (Table 1). These are, among others: an urban section within Dęblin boundaries (km 388-393 of the river), a fragment adjacent to Kozienice Power Plant (km 421-426), and the area, where since 2007 gravel for the industry has been mining from the river bottom (km 426-431). The aim of this inventory was the comparison of richness and abundance of breeding bird species associated directly with the river channel on fragments mentioned above. It will allow us to estimate soberly how very the intensity of human utilization of the river affects the distribution of avifauna of the Vistula, determining the richness and abundance of valuable and/or endangered species breeding in a given area.

Abstract The article deals with trends in the Eurasian eagle-owl (Bubo bubo) population in Czechia and the interplay between legal regulation of hunting and nature protection. In the early 20th century, the eagle-owl population in Bohemia decreased to an estimated 20 nesting pairs, and the population in Moravia and Silesia was subsequently estimated to be similarly low. In previous centuries, eagle-owls had been persecuted as pest animals; additionally, their chicks were picked from nests to be kept by hunters for the eagle-owl lure hunting method (“výrovka” in Czech), where they were used as live bait to attract corvids and birds of prey, which were subsequently killed by shooting. As soon as the state of the eagle-owl population was established in the 1900s, the effort to save the autochthonous eagle-owl population commenced. Nevertheless, when eagle-owls became legally protected from killing in the 1930s, the eagle-owl lure hunting method was not prohibited. The intensified use of this hunting method in the 1950s was accompanied by serious decline in the populations of birds of prey in the Czech countryside, when tens of thousands of Eurasian sparrowhawks (Accipiter nisus), northern goshawks (Accipiter gentilis), common buzzards (Buteo buteo) and rough-legged buzzards (B. lagopus) were killed on a yearly basis. The usage of eagle-owl chicks in lure hunting was criticised by ornithologists concerned with the conservation of birds of prey. The eagle-owl thus became a subject of more general debate on the role of predators in nature, and this debate (albeit regarding other predator species) has continued to the present-day. As the eagle-owl population has been growing steadily following the prohibition of its killing in the 1930s, its story may serve as an example of the need for effective legal protection of predators to ensure their survival in the intensively exploited central-European environment. The article examines the successful preserving of the eagle-owl in the Czech countryside, from its low point in the early 20th century towards today’s stable and ever-increasing population, focusing on environmental, conservationist, legal and societal aspects of the issue.

Abstract Population of the Eagle Owl (Bubo bubo) has been increasing in Europe including Hungary. The species occupy new habitats beside its ancient territories including quarries and buildings. This may result in conflicting conservation and economic interests in active quarries. Because eagle owls are strictly protected in Hungary, human activities around known nest sites require environmental permits. We aimed to obtain information on Eagle Owl behaviour in an operating quarry by tracking an adult female to base a future species-specific guideline to issue environmental permits for mining in quarries. We used a combined GPS-GSM and VHF telemetry. We found that the tracked female did not breed in the study year but remained in her home range during the study period. By studying her seasonal and daily patterns of movements, we found that she was not disturbed by regular human activities under the nesting cliff, but she was more sensitive to unexpected non-regular disturbance. Based on the satellite-tracking data, this specimen used an approximately 18 km2 home range during the study period.

LABURPENA: Iruzkinak 2011ko otsailaren 18ko epaiarekin zerikusia du. Honetan Euskal Autonomia Erkidegoko Justizia Auzitegi Nagusiak, bere egunean euskal Administrazioak Ordunten eraiki beharreko parke eolikoari buruz egindako ingurumenaren gaineko eraginaren aurkako aitorpena Zuzenbidearekin bat ez zetorrela ondorioztatu zuen. Erabilitako arrazoien artean, Auzitegiaren ustetan, Eusko Jaurlaritzak ez zituen Natura 2000 sareko gune batean egin beharreko proiektuak planteatutako eragin kritikoak modu egokian arrazoitu. RESUMEN: El comentario tiene que ver con una sentencia de 18 de febrero de 2011, en la que el Tribunal Superior de Justicia del País Vasco (TSJ) llegó a la conclusión de que la declaración de impacto ambiental (DIA) desfavorable, que dictó en su día la Administración autonómica en relación con la construcción de un parque eólico en Ordunte, no era conforme a Derecho. Entre otras razones, el Tribunal indicó que el Gobierno Vasco no había motivado de manera suficiente los impactos críticos que, en su opinión, planteaba el proyecto en una zona de la red Natura 2000. ABSTRACT: The comment concerns a judgment of the High Court of the Basque Country of 18 February 2001 that held that the unfavorable environmental declaration issued by the Basque Government regarding a wind farm was not consistent with applicable laws. The Court held, inter alia, that the Government had not provided sufficient reasons to sustain the assumption that the project embraced critical environmental impacts on a Natura 2000 site.
