Big part of the site represents the same-named National Nature Re- serve. This site was included to the NATURA 2000 network due to the occurrence of several rare species, natural sceneries and biotops. Major part of site is situat ed in the north-eastern part of the Branisko Mts and minor part in the south-west- part of the Bachureň Mts. These mountains are one of the least known areas from the malacological point of view.

IVAILO KANEV DEDOV Central Laboratory of General Ecology, 2 Gagarin Str., BG-1113 Sofia, Bulgaria, e-mail: [email protected] DEDOV I.K., 2008: Terrestrial gastropods (Mollusca, Gastropoda) of the Bulgarian part of the Alibotush Mts. – Malacologica Bohemoslovaca, 7: 17–20. Online serial at <http://mollusca.sav.sk> 20-Feb-2008. This work presents results of two years collecting efforts within the project “The role of the alpine karst area in Bulgaria as reservoir of species diversity”. It summarizes distribution data of 44 terrestrial gastropods from the Bulgarian part of Alibotush Mts. Twenty-seven species are newly recorded from the Alibotush Mts., 13 were con- firmed, while 4 species, previously known from the literature, were not found. In the gastropod fauna of Alibotush Mts. predominate species from Mediterranean zoogeographic complex. A large part of them is endemic species, and this demonstrates the high conservation value of large limestone areas in respect of terrestrial gastropods.

Mickiewicza 30, 30-059 Cracow, Poland (e-mail: [email protected]); https://orcid.org/0000-0002-5403-6696 abstract: Long-term research on the malacofauna of the Beskid Mały, one of the ranges of the Western Beskidy Mts, was based on flood deposits of the streams cutting through the massif. Samples from limestone areas (called Andrychów Klippes) and those from the Żurawnica massif complemented the material. The total of ca. 400 samples yielded 78 species of terrestrial snails. The malacofauna was characterised in terms of its ecological and zoogeographical composition. The material provided the basis for determining the zones of occurrence and distribution of the component taxa within the Beskid Mały range. The ecological, zoogeographical and species diversity of the assemblages made it possible to distinguish four types of fauna, each connected with certain parts of the Beskid Mały range, which differ in their geological structure, relief and the degree of anthropogenic transformations. Key Words: terrestrial snails, biodiversity, Beskid Mały, Carpathians, southern Poland INTRODUCTION Research on the malacofauna of the Polish floodplains during high water levels.

    EIAR Kilcumber Bridge 110kV substation Chapter 4: Biodiversity 4 BIODIVERSITY 4.1 INTRODUCTION This chapter describes the ecology in the environs of the proposed substation site and grid connection route and assesses the potential effects of the project on identified ecological receptors. A detailed description of the project assessed in this chapter is given in Chapter 2 Project Description. A Natura 2000 Appropriate Assessment Natura Impact Statement (NIS) report has also been prepared and completed for the project. This Ecological Impact Assessment was carried out with regard to the following publications: • Guidelines on the Information to be Contained in Environmental Impact Assessment Reports (EPA, 2017); • Guidelines for Ecological Impact Assessment in the UK and Ireland - Terrestrial, Freshwater, Coastal and Marine (IEEM, 2019); • Guidelines for Assessment of Ecological Impacts of National Road Schemes (NRA, 2009). 4.1.1 Legislation and Policy Context The most important legislation underpinning biodiversity and nature conservation in Ireland are the: • Wildlife Acts 1976 to 2012; • European Communities (Birds and Natural Habitats) Regulations 2011-2015 (transposes EU Birds Directive 2009/147/EC and EU Habitats Directive 2009/147/EC, 92/43/EC); • European Communities (Quality of Salmonid Waters) regulations (S.I. No. 84 of 1988); • Freshwater Fish (78/659/EEC) The Wildlife Act, 1976, is the principal national legislation providing for the protection of wildlife and the control of some activities that may adversely affect wildlife. The aims of the Wildlife Act, 1976, are to provide for the protection and conservation of wild fauna and flora, to conserve a representative sample of important ecosystems, to provide for the development and protection of game resources and to regulate their exploitation, and to provide the services necessary to accomplish such aims.

  • Land Snails of Leicestershire and Rutland

    Land Snails of Leicestershire and Rutland

    Land Snails of Leicestershire and Rutland Introduction There are 50 known species of land snail found in Leicestershire and Rutland (VC55) which represents about half of the 100 UK species. However molluscs are an under-recorded taxon group so it is possible that more species could be found and equally possible that a few may now be extinct in our two counties. There was a 20 year period of enthusiastic mollusc recording between 1967 and 1986, principally by museum staff, which account for the majority of species. Whilst records have increased again in the last three years thanks to NatureSpot, some species have not been recorded for over 30 years. All our land snails are in the class Gastropoda and the order Pulmonata. Whilst some of these species require damp habitats and are generally found near to aquatic habitats, they are all able to survive out of water. A number of species are largely restricted to calcareous habitats so are only found at a few sites. The sizes stated refer to the largest dimension of the shell typically found in adult specimens. There is much variation in many species and juveniles will of course be smaller. Note that the images are all greater than life size and not all the to the same scale. I have tried to display them at a sufficiently large scale so that the key features are visible. Always refer to the sizes given in the text. Status refers to abundance in Leicestershire and Rutland (VC55). However molluscs are generally under- recorded so our understanding of their distribution could easily change.

    © Biologiezentrum Linz/Austria; download unter www.biologiezentrum.at Beitr. Naturk. Oberösterreichs 9 729-737 2000 Die Gastropodenfauna der Staninger Leiten in Steyr1 F. SEIDL A b s t r a c t : In 1997 investigations on the gastropod fauna of a semidry meadow ("Staninger Leiten", Upper-Austria) have been carried through. A total of 15 species with 5 species mentioned in the Red Data List was found. In the wood beside the meadow 19 species (2 in Red Data List) have been counted. The gastropod fauna of the Staninger Leiten is compared with another semidry meadow of the region, Neuzeug- Keltenweg. Keywords: gastropod fauna, semidry meadow, semidry grassland, Upper- Austria Einleitung Zur Molluskenfauna von Steyr liegen bereits Daten von LA VOGLER (1890), KLEMM (1954, 1974) und REISCHÜTZ (1986) vor. Die Angaben sind zum Teil genauer, denn es werden auch Stadtteile (z.B. Christkindl, Ennsleiten, Gleink) als Fundstellen genannt, zum Teil aber auch recht allgemein gehalten (z.B. Umgebung Steyr). Die Staninger Leiten wird in diesen Publikationen nicht erwähnt. Die Leiten dürfte demnach 1997 erst- mals malakologisch untersucht worden sein. Der namensgebende Ort Staning liegt zwar bereits im Bezirk Steyr-Land, die Staninger Leiten befindet sich aber noch auf dem Gebiet der Stadtgemeinde Steyr und zwar im nordöstlichsten Teil des Gemeindegebietes. Der in Frage kommende Teil der Leiten ist ein SO-exponierter Steilhang, der oben von einem Fahrweg begrenzt wird. An den Hang- fuß grenzen ebene Fettwiesen und Felder. Die Leiten gliedert sich in einen Halbtrocken- rasen, einen erst in neuester Zeit gerodeten Bereich und einen bewaldeten Teil (vgl. HAUSER et al.
