Prunus lusitanica L. is a paleotropical relic species with an Ibero-Maghrebian distribution, which is presently considered as an endangered species, recognized by the Natura 2000 Network (92/43/EEC) as a priority habitat for conservation in Europe. The mountains in the Portuguese mainland central region offer the best location for this species to occur. The main objective of this study is to measure the current conservation status of the communities of P. lusitanica, through the collection of field data, such as the number of existing individuals of each population and their location, which will then be comparatively analyzed based on the previous literature, published at least 15 years ago. Soil characterization analysis was carried out and the main threats to conservation were identified. As a result, a decline of approximately 40% was observed in the number of individuals and in the quality of their habitat. The main threats to their conservation were found to be the seasonal occurrence of rural fires and the expansion of invasive species, such as Acacia dealbata Link and Ailanthus altissima (Mill.) Swingle. Finally, we present the main management methodologies that should be considered for the valorization of this important vegetational relic in the central region of mainland Portugal.

Land-Use Cover Changes (LUCCs) are one of the main problems for the preservation of landscapes and natural biodiversity. Protected Areas (PAs) do not escape this threat. Poland is among the European leaders in terms of the variety of landscapes and the share of an area designated as a protected area. However, as many as 78% of the habitats have poor or bad conservation status based on EEA reports. This article analyzes the LUCCs between 2000 and 2018 in various types of the Polish legal forms of nature protection areas and the European Natura 2000 network within the country. The research material was: the data of Corine Land Cover (CLC), the Central Register of Nature Protection Forms, and high-resolution layers, such as HRL and orthophotos. The results were compiled according to the CLC class and forms of protection. The matrix of transformations showed that the most frequently transformed CLC class was 312 (coniferous forest). It was transformed into class 324 (transitional woodland shrubs). The changes in PAs were usually smaller than in the surrounding buffer zones, which may indicate their effectiveness. The exception was the areas of the European Natura 2000 network. The scale of land-cover flows (LCFs) changed within particular forms of protected areas, though afforestation and deforestation predominating in all area types. National reserves and parks were the most stable in terms of land cover structures. However, human settlements increased around the protected areas, potentially increasing threats to their ecological integrity.

Abstract The riparian softwood galleries of the Scroafa Stream basin, part of the South Eastern Transylvanian Tableland are presented and discussed under the aspect of their site conditions, species composition, vertical structure by different layers, ecological requirements and their change along the stream banks from the source to the mouth in the Târnava Mare River. Their stretches are compared, with commonalities and differences highlighted. The impact of human dependent changes and the future of the galleries with climate changes are addressed. The importance of the riparian softwood stands is also presented in the context of the Natura 2000 network, as they are included in the list as priority habitat types.

Abstract The paper presents the spring habitats and their communities edified by the Large Bitter Cress (Cardamine amara L.) in the area of Nergăniţa, a headwater stream of the Nera River included in the “Nature Reserve Semenic Mountains and springs of Nera River”. The communities of Large Bitter Cress are situated in and on the springs and spring streamlets situated in the beech forest area, being well adapted to the special site conditions with low water temperatures, low light conditions and humus rich soils. The species composition of the Large Bitter Cress communities and their habitats are presented in strong relation with the habitat conditions and the interrelation with other communities. Finally, the conservation status of the streamlets habitats is analyzed in the context of their importance for the European Natura 2000 network.

Abstract The vegetation of the European Natura 2000 protected area of Spercheios river and Maliakos gulf, that includes Mediterranean sclerophyllous shrublands, as well as riverine and coastal habitats, was studied during 2000 and 2014–2015. The vegetation was analysed following the Braun-Blanquet method. Twenty six plant communities were recorded, one of which (Pistacio terebinthi-Quercetum cocciferae) described for the first time. The communities belong to fifteen alliances, fourteen orders and eleven phytosociological classes. The distinguished vegetation units are described, presented in phytosociological tables and compared with similar communities from other Mediterranean countries. Eleven different habitat types were identified. Two of them (“Quercus coccifera woods” and “Reed beds”) are Greek habitat types, while the rest are included in Annex I of the Directive 92/43/EEC. Three of the latter (1420, 2110, 3170) have a scattered presence in the Natura 2000 network in Greece, while one (3170) is a priority habitat type.

Riparian Habitats

Riparian habitats provide a series of ecological services vital for the balance of the environment, and are niches and resources for a wide variety of species. Monitoring riparian environments at the intra-habitat level is crucial for assessing and preserving their conservation status, although it is challenging due to their landscape complexity. Unmanned aerial vehicles (UAV) and multi-spectral optical sensors can be used for very high resolution (VHR) monitoring in terms of spectral, spatial, and temporal resolutions. In this contribution, the vegetation species of the riparian habitat (91E0*, 3240 of Natura 2000 network) of North-West Italy were mapped at individual tree (ITD) level using machine learning and a multi-temporal phenology-based approach. Three UAV flights were conducted at the phenological-relevant time of the year (epochs). The data were analyzed using a structure from motion (SfM) approach. The resulting orthomosaics were segmented and classified using a random forest (RF) algorithm. The training dataset was composed of field-collected data, and was oversampled to reduce the effects of unbalancing and size. Three-hundred features were computed considering spectral, textural, and geometric information. Finally, the RF model was cross-validated (leave-one-out). This model was applied to eight scenarios that differed in temporal resolution to assess the role of multi-temporality over the UAV’s VHR optical data. Results showed better performances in multi-epoch phenology-based classification than single-epochs ones, with 0.71 overall accuracy compared to 0.61. Some classes, such as Pinus sylvestris and Betula pendula, are remarkably influenced by the phenology-based multi-temporality: the F1-score increased by 0.3 points by considering three epochs instead of two.

Abstract Peat bogs and specially raised bogs are vulnerable ecosystems all over the world and they create refuges for some rare plant species. The aim of this paper is to provide information regarding the conservation status of five oligotrophic peat bogs situated in the volcanic mountains in the Oriental Chain of Carpathians, in Maramureș County. The studied peat bogs are: Tăul lui Dumitru (Dumitru Pond), Mlaștina Vlășinescu (Vlășinescu Peat bog), Iezeru Mare (Big Tarn), Tăul Chendroaiei (Chendroaiei Pond) and Tăul Negru (Black Pond), all of them have the status of nature reserve and under the IUCN categories they are included in category IV Habitat/Species Management Area (www.iucn.org, 2016). The analysis of the selected peat bogs reveals that all five of them have the vegetation included in the Natura 2000 priority habitat 7110* Active raised bogs. The conservation status of these peat bogs was evaluated and it is variable from moderate to very good conservation status.

The caterpillars of the Southern Swallowtail, Papilio alexanor have been recorded in the vicinity of Trebinje, Bosnia & Herzegovina. This is the first recent observation of this species in the country and the third observation so far. Opopanax chironium is confirmed as the larval host plant in Bosnia and Herzegovina, which was expected due to the recent observations from Croatia. Its status and distribution in the country are still not clear, and further surveys are recommended in order to reconfirm the historical records as well as to assess its current conservation status. Due to the limited extent of its occurrence, we propose to include it in the Red list of fauna of Bosnia & Herzegovina as Vulnerable (VU).
