Landscape Changes in Protected Areas in Poland

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.

Confirmation of the presence of steppe polecat Mustela eversmanii (Carnivora: Mustelidae) in Giurgiu County (Romania) after more than 5 decades

This paper confirms the presence of steppe polecat Mustela eversmanii in Giurgiu County after more than 50 years. Mustela eversmanii is considered a vulnerable species, being listed in Annexes II and IV of the Habitats Directive. The specimen was found within the Site of Community Importance - ROSCI0043 Comana, included in the Natura 2000 network, which significantly overlaps with the protected natural area (Comana Natural Park). Currently, the steppe polecat is not added to the list of the Standard Form, because its presence was uncertain. We consider that this discovery is valuable and has important implications for the conservation of the species.

Oribatid mites (Acari, Oribatida) from “Parco Naturale delle Alpi Marittime” (Piedmont, Italy)

Oribatid mites were investigated in six sites in the Alpi Marittime Natural Park (Prov. Cuneo, Piedmont, northern Italy) which is part of the NATURA 2000 network. The selected locations cover 4 forested (fir, ash, 2 beech forests) and 2 grassland sites (mountain meadow, xeric grassland). Altogether 173 described oribatid species belonging to 51 families were encountered, complemented by one undetermined species (Scheloribates (Topobates) cf. carpathicus), added together 174 species. Among them 11 species are new records for Italy. A comparison with other Italian alpine provinces shows high similarity of the oribatid species composition from the investigated sites with the provinces of Bolzano, Trento, Sondrio. A total of 37 species from the Marittime Alps has also been recorded in the southern part of the nearby Swiss canton Ticino. The majority of the species in the investigated sites are known as silvicolous; xerophilous species were mainly found in the xeric grassland site at lower altitude. High species similarities are observed between the forested sites, which also show high species numbers (up to 96 spp. found in the fir forest), lowest similarities are found between the open grassland sites and the forested sites, as well as between the grassland sites themselves.

Improving Scientific Knowledge of Mallorca Channel Seamounts (Western Mediterranean) within the Framework of Natura 2000 Network

The scientific exploration of Mallorca Channel seamounts (western Mediterranean) is improving the knowledge of the Ses Olives (SO), Ausias March (AM), and Emile Baudot (EB) seamounts for their inclusion in the Natura 2000 network. The aims are to map and characterize benthic species and habitats by means of a geological and biological multidisciplinary approach: high-resolution acoustics, sediment and rock dredges, beam trawl, bottom trawl, and underwater imagery. Among the seamounts, 15 different morphological features were differentiated, highlighting the presence of 4000 pockmarks, which are seafloor rounded depressions indicators of focused fluid flow escapes, usually gas and/or water, from beneath the seabed sediments. So far, a total of 547 species or taxa have been inventoried, with sponges, fishes, mollusks, and crustaceans the most diverse groups including new taxa and new geographical records. Up to 29 categories of benthic habitats have been found, highlighting those included in the Habitats Directive: maërl beds on the summits of AM and EB, pockmarks around the seamounts and coral reefs in their rocky escarpments as well as fields of Isidella elongata on sedimentary bathyal bottoms. Trawling is the main demersal fishery developed around SO and AM, which are targeted to deep water crustaceans: Parapenaeus longirostris, Nephrops norvegicus, and Aristeus antennatus. This study provides scientific information for the proposal of the Mallorca Channel seamounts as a Site of Community Importance and for its final declaration as a Special Area of Conservation.

The role of Natura 2000 network in protecting the orchid flora of East Macedonia (NE Greece)

East Macedonia (northeast Greece) is a relatively small part of Greece, where a considerable number of orchid taxa occurs. Some of these orchids can only be found there and this fact makes the specific area of Greece unique. In this study, an up-to date database of orchid records was used to assess the effectiveness of the existing Natura 2000 network. Specifically, the effectiveness of the Natura 2000 network was evaluated by identifying the number of orchids whose distribution is overlapping to a lesser or greater extent with the network, which chorological categories are included/excluded from it, and whether the rare and threatened orchid taxa are adequately distributed within that. Out of the 73 orchid taxa recorded in East Macedonia so far, 14 taxa are exclusively distributed outside the Natura 2000 network. Specifically, the Natura 2000 network is not overlapped with a number of Balkan and Mediterranean orchid taxa, which are only sparsely found in East Macedonia. Moreover, most of the orchid taxa that have been classified in the threat categories of the IUCN are distributed within the Natura 2000 network of East Macedonia, and specifically, some of the most threatened ones are almost exclusively distributed within that network. Consequently, although the Natura 2000 network is not congruent with the distribution of a number of species of southern origin, which are widely distributed elsewhere in Greece, it can conserve important floristic elements of Greece, which are orchid taxa of northern or central European origin.

Natura 2000 Network vs. Tourism and Investment Potential of Communes—A Case Study of Czarnkowsko-Trzcianecki County

The Natura 2000 is a network of protected areas established in the European Union on the basis of EU Directives. Simultaneously it is the youngest form of protected areas in Poland. Hence conflicts between conservation objectives and opportunities as well as needs of community economic development are quite common. The aim of the present study was to evaluate the tourism and investment potential of Czarnkowsko-Trzcianecki County and determine whether the Natura 2000 network is a factor in increasing the tourism and investment development of the commune or limiting it. We evaluated the tourism and investment potential based on modification of the Gołembski method (i.e., multidimensional comparative analysis) and measured the proportion of the Natura 2000 network in the total area of the commune. The Trzcianka commune was found to have the greatest tourism development and investment potential, but the Wieleń commune was the most attractive in terms of tourism, and Czarnków (municipal commune) was found to have the highest investment attractiveness. Moreover, there was no correlation between the Natura 2000 network and tourism and investment potential of communes. However, these areas had a negative impact on the investment attractiveness of communes, due to socio-economic and technical aspects, which may cause future potential limitation of development.

How Effective Are the Protected Areas of the Natura 2000 Network in Halting Biological Invasions? A Case Study in Greece

Invasive alien plant species represent an important threat to various protected areas of the world, and this threat expected to be further enhanced due to climate change. This is also the case for the most important network of protected areas in Europe, the Natura 2000 network. In the current study we evaluated the distribution pattern of alien plant taxa across selected continental and insular Natura 2000 sites in Greece and their potential spread 15 years since first being recorded in the field. A total of seventy-three naturalized plant taxa were recorded in the 159 sites under study. At the site level and regardless of the habitat group, the ratio of invaded areas increased between the two monitoring campaigns. An increase in the ratio of invaded plots was also detected for all habitat groups, except for grassland and riparian—wetland habitats. Precipitation during the dry quarter of the year was the factor that mainly controlled the occurrence and spread of alien plant taxa regardless of the site and habitat group. It is reasonable to say that the characterization of an area as protected may not be sufficient without having implemented the proper practices for halting biological invasions.

A Quantitative GIS and AHP Based Analysis for Geodiversity Assessment and Mapping

In recent times, the issues of geodiversity assessment and mapping have been subject of great attention, and many evaluation methodologies, either quantitative or qualitative, have been developed. In this research, a first assessment of geodiversity in the Liguria region has been carried out, according to a quantitative method based on spatial analysis techniques implemented in a GIS environment. This method considers four diversity indices obtained by grid analysis, relevant to the four main aspects of geodiversity: geology, geomorphology, hydrogeology and pedology. The geodiversity index was calculated two times, first with a non-weighted sum, then with a weighted sum of the four diversity indices. In the second case, the weights have been assigned according to a semi-quantitative analytical hierarchy process method (AHP) based on experts’ judgment. The results show that the Liguria region is characterized by many areas with high geodiversity, most of them internationally known by geoscientists and tourists for their valuable geoheritage and for their stunning landscapes. The correspondence between these areas and the protected areas of the european Natura 2000 network suggests a link between geodiversity and biodiversity.
