AbstractThe Eurasian lynx Lynx lynx population in the Carpathian Mountains is considered to be one of the best preserved and largest in Europe and hence is a source for past and current reintroduction projects in central Europe. However, its status in Slovakia has been reported to the European Commission on the basis of hunters´ reports and expert estimates that have never been validated by a robust scientific approach. We conducted the first camera-trapping surveys to estimate the density of Eurasian lynx in Slovakia by means of spatial capture–recapture models in two reference areas during 2011–2015. We estimated population density per 100 km2 of suitable lynx habitat (posterior SD) as 0.58 ± SD 0.13 independent individuals (adults and subadults) in the Štiavnica Mountains and 0.81 ± SD 0.29 in Veľká Fatra National Park and surroundings. These are the lowest densities estimated using spatial capture–recapture models so far reported for the species, suggesting the lynx population in Slovakia is below carrying capacity. We suspect that low densities may be attributable to undetected human-caused mortality. Our results imply that official game statistics are substantially overestimated. Moreover, the lynx population in Slovakia may not be at favourable conservation status as required by the EU Habitats Directive. We therefore call for a thorough assessment of the density and trend of the Slovak Carpathian lynx population, and the establishment of a scientifically robust monitoring system.

AbstractSerpentine outcrops are distinct from their background geological context, as they are often isolated from one another, and provide a home to a significant number of rare or endemic taxa. The aim of this study was to assess the Portuguese populations of one such taxon, Notholaena marantae subsp. marantae, including information on its biogeography, habitat, geographical range and conservation status. A detailed study was also made of the endemic association Notholaenetum marantae, a member of the Phagnalo saxatilis-Cheilanthion maderensis alliance, a type of vegetation included in the EU Habitats Directive 92/43/ECC. The distribution of Notholaena marantae was highly fragmented, with two sites accounting for over 50% of the total number of individuals recorded. The presence of N. marantae is associated with that of ultramafic rocks, which show specific geochemical features. The conservation status of the species is a cause for concern. We propose that the species be considered ‘vulnerable’ according to the criteria of the IUCN (2001), and that areas where its populations grow be protected. This study confirms the endemic status of N. marantae subsp. marantae in Portugal and the importance of the conservation of its serpentine habitats.

The Hutě Nature Reserve is located in the central eastern part of the White Carpathians PLA, near the Žítková village. The reserve protects a preserved and topographically heterogeneous area composed of forest groves, meadows, pastures, and spring fens with a high diversity of submontane and thermophilic plant and animal assemblages. The species composition of molluscs (9 out of 10 ecological groups represented) consists mainly of woodland dwellers, which account for the majority of species diversity (30 spp.; 52%), followed by ubiquitous (9; 16%), hygrophilous (5; 9%), hygrophilous woodland dwellers (4; 7%), aquatic (4; 7%) and open-habitat dwellers (3; 5%). Vertigo moulinsiana (EN), internationally protected under Annex II of the EU Habitats Directive, Daudebardia brevipes (VU), Ambigolimax nyctelius (NT), Orcula dolium (NT) and Bythinella austriaca (NT) are species of conservation concern. To retain favourable habitat conservation status, the spring fens with V. moulinsiana occurrence must be managed extensively by grazing or mowing, while the forests must remain in a non-intervention regime.

Coastal habitats are highly threatened ecosystems that are sensitive to complex sets of natural and human drivers. Europe’s coastal habitats are protected from damage due to human activity by the EU Habitats Directive, and are required to be mapped within flood risk assessments by the EU Floods Directive. Ecological vulnerability and risk assessments are a common way of assessing the impacts on these habitats due to human and natural drivers. Coastal flood risk assessments therefore often include assessments of the vulnerability of coastal habitats. Flood risk assessments also evaluate, where relevant, the mitigation services provided by coastal habitats. The two aspects of coastal habitats – their flood mitigation service and their ecological vulnerability are strongly correlated; however these are usually treated separately within flood risk assessments. One of the goals of the EU THESEUS project is the integrated consideration of coastal habitats within flood risk assessments. This paper investigates the integration within flood risk assessments of the two aspects of coastal habitats using the 2D SPR conceptual model. The construction of the model is first illustrated by application to a generic study site. The model is then applied to a case-study where data on habitat elevations and vulnerabilities to flood events have been collected. The model provides a unique and robust means of combining information on ecological vulnerability indices for different habitat associations with information on their distribution and spatial relationships within the coastal floodplain. Used in conjunction with information on habitat vulnerability indices, the conceptual model serves as a powerful tool for integrated and structured consideration of coastal habitats within flood risk assessments

Abstract Soft water lakes, or so-called lobelia lakes, which are inhabited by a specific vegetation composed of isoetids, have been subjected to intense research aimed at evaluating their condition and conservation status for many years in Poland. At the time of Poland’s accession to the European Union and the implementation of the EU Habitats Directive, these lakes were classified as natural habitat 3110. In accordance with the provision of the Habitat Directive a comprehensive methodology for monitoring and classification of the state of this habitat has been developed. Using this methodology, two monitoring trials (in 2009–2010 and again in 2016–2017) were carried out at 45 and 43 sites of the 3110 natural habitat, respectively. These studies confirm the high sensitivity of these poorly buffered aquatic ecosystems to all external influences, both natural and anthropogenic. The overall conservation status of the 3110 habitat in Poland showed a relatively high stability, with similar proportions of sites classified as favourable (FV), unfavourable inadequate (U1) and unfavourable bad (U2) between 2009–2010 (35%, 49% and 16%, respectively) and 2016–2017 (33%, 56% and 11%, respectively). Out of 43 sites examined in 2016–2017, 29 remained unchanged compared with the results of the previous survey concerning their overall status. Results of the monitoring research also allow for the observation and evaluation of mechanisms and directions of changes in the functioning of these ecosystems. Based on the experiences from two series of monitoring conducted so far, the methodology has been assessed as appropriate for the assessment of the conservation status of the 3110 natural habitat, however, some modifications and additions have been suggested.

Since alluvial meadows of river valleys of the Cnidion dubii are protected by the EU Habitats Directive, reconciling farmers’ demands for forage quality with the objective of maintaining them in good conservation status is an important issue in grassland research. In a long-term experiment from 2010 to 2018, we investigated the impact of fertilizing on forage quality and species assembly on a species-rich and twice-mown alluvial grassland in the Dessau Elbe floodplain (Germany). The experiment was composed of an unfertilized control, PK, N60, N60PK and N120PK applications. A significant improvement in forage quality was achieved by nitrogen fertilization only for crude protein, with higher feeding requirements for sheep met only in individual years. The legume cycle was inhibited by the application of nitrogen and high grass cover was maintained, but not increased, at the highest nitrogen application after an exceptional summer flood. The target forbs persisted in numbers over the study period in all treatments. For cover, the low-competitive target forbs responded neutrally to nitrogen fertilization, whereas detrimental effects were demonstrated for the competitive ones. Thus, we recommend not applying more than 60 kg year−1 of nitrogen and only in combination with phosphorus and potassium.

The Shannon Estuary in Ireland is home to a resident population of bottlenose dolphins (Tursiops truncatus) and is designated as a Special Area of Conservation under the EU Habitats Directive. It is an important industrial area, with numerous deep-water berths for shipping. Despite its high conservation value, there are few published studies on habitat use or foraging behavior of the Shannon dolphins throughout the year. The present study assessed the year-round presence and foraging activity of bottlenose dolphins at different locations in the middle and inner estuary using static acoustic monitoring. Dolphin presence was found to decrease with increased distance from the estuary mouth, i.e., where the estuary meets the Atlantic Ocean, while at the same time, foraging was found to be considerably higher in the upriver areas, suggesting the inner estuary was an important foraging area. Model predictions for seasonal, tidal and diel foraging were highly variable across locations, indicating that changes in dolphin behavior occurred over relatively small geographical scales. These results indicate that conservation efforts should consider the Shannon Estuary as a dynamic aggregation of habitats and future development initiatives should attempt to mitigate disturbance to the dolphins during important foraging periods on seasonal and diel scales.

Abstract The dioicous epixylic liverwort Cephalozia macounii (Aust.) Aust. is rare over its entire distribution area in the Northern Hemisphere. It is protected under the EU Habitats Directive and classified as critically endangered in Finland and Sweden. One reason cited for its rareness and the declining trend in its distribution its poor reproductive capacity. It does not produce asexual gemmae, which in general is common among liverworts. Although female plants with perianths are quite common, the male plants of the species have rarely been seen and sporophytes have not been described until now. In this paper we describe and illustrate the sporophytes of C. macounii on the basis of an old specimen collected in Southern Finland in the 1800s.

Metsamardikate (Coleoptera) uued liigid Eestis The article presents faunistic data on 85 species of Coleoptera new to the Estonian fauna. Most of the material has been collected within the framework of various research and monitoring projects carried out in Estonian nature reserves (1998-2009). A new type of trunk window trap, designed by the author in 2004 mainly for monitoring purposes, has been successfully used. 17 of the 85 species are new for the fauna of whole Baltic region: Pseudeuglenes pentatomus (Ths.) (Aderidae), Caenocara subglobosum (Muls. & Rey), Xyletinus tremulicola Y. Kangas (Anobiidae), Choragus sheppardi Kirby (Anthribidae), Cryptocephalus saliceti Zebe (Chrysomelidae), Dirrhagofarsus attenuatus (Mäklin), Hylis cariniceps (Rtt.), Microrhagus emyi (Rouget) (Eucnemidae), Gnathoncus communis (Marseul) (Histeridae), Notolaemus unifasciatus (Latr.) (Laemophloeidae), Agathidium discoideum Er. (Leiodidae), Anisoxya fuscula (Ill.) (Melandryidae), Mordellistena neuwaldeggiana (Pz.) (Mordellidae), Ripidius quadriceps Abeille de Perrin (Rhipiphoridae), Lissodema cursor (Gyll.) (Salpingidae), Aphodius quadrimaculatus (L.) (Scarabaeidae) and Eutheia schaumii Kiesw. (Scydmaenidae). One of the species, Caenocara subglobosum (Muls. & Rey) (Anobiidae), is new for the whole Northern Europe. Specimens of this species were collected from eastern and southern Estonia: most were caught in window traps but some also emerged from the collected fruiting bodies of Common Puffball (Lycoperdon perlatum). For 21 new species, Estonia lies on the northern edge of their range. Three of these, Triphyllus bicolor (F.), Mycetophagus ater (Rtt.) and Glischrochilus grandis (Tournier) that were collected from 6-10 sites, have a wider distribution in Estonia. Two species, Xyletinus tremulicola Y. Kangas (Anobiidae) and Stephanopachys linearis (Kug.) (Bostrichidae), have been listed on Annex II of the EU Habitats Directive. Two new species (Lymantor aceris (Lindemann) and Xyleborinus saxesenii (Ratz.)) were also added to the list of Estonian bark beetles (Curculionidae: Scolytinae).
