  • Restoration of Fish Passage and Results of a Master Plan Established for the Ruhr River Basin
    RR 2004 3rd European Conference on River Restoration RIVER RESTORATION 2004 Zagreb, Croatia, 17-21 May 2004 Restoration of fish passage and results of a master plan established for the Ruhr River Basin Marq Redeker, Michael Weyand, Ernst A. Nusch ABSTRACT: According to the central aim of the European Water Framework Directive, the ecological and chemical conditions will be primary quality elements in future for surface waters. Population diversity and abundance of fish and macroinvertebrates is decisive in aiming at the good ecological status in surface water bodies,. Free passage in river systems is a prerequisite to allow the natural migration of fish and other aquatic organisms. In order to point out potentiali- ties for the Ruhr River Basin a study was commissioned to develop a master plan for river conti- nuity restoration. This study was complemented by investigations into the sediments in the riv- ers, in order to identify river sections or tributaries which presumably provide a suitable habitat for the successful reproduction of salmonides. The master plan illustrates the inherent problems of projects aimed at the restoration of fish migration in surface waters which are strongly affected by anthropogenic modifications. The results obtained can be transferred to other river basins with similar conditions. KEYWORDS: European Water Framework Directive, river basin management, river restoration, river continuity, fish passage, fishway, hyporheic interstitial, master plan 1 Introduction The European Water Framework Directive (WFD) [1] came into force in December 2000. Its central goal is the protection and sustainable management of the aquatic eco- systems. According to the new provisions, the quality of surface waters is assessed by biological and chemical elements, as well as various hydromorphological parameters supporting the biological elements.

  • Finished Vehicle Logistics by Rail in Europe
    Finished Vehicle Logistics by Rail in Europe Version 3 December 2017 This publication was prepared by Oleh Shchuryk, Research & Projects Manager, ECG – the Association of European Vehicle Logistics. Foreword The project to produce this book on ‘Finished Vehicle Logistics by Rail in Europe’ was initiated during the ECG Land Transport Working Group meeting in January 2014, Frankfurt am Main. Initially, it was suggested by the members of the group that Oleh Shchuryk prepares a short briefing paper about the current status quo of rail transport and FVLs by rail in Europe. It was to be a concise document explaining the complex nature of rail, its difficulties and challenges, main players, and their roles and responsibilities to be used by ECG’s members. However, it rapidly grew way beyond these simple objectives as you will see. The first draft of the project was presented at the following Land Transport WG meeting which took place in May 2014, Frankfurt am Main. It received further support from the group and in order to gain more knowledge on specific rail technical issues it was decided that ECG should organise site visits with rail technical experts of ECG member companies at their railway operations sites. These were held with DB Schenker Rail Automotive in Frankfurt am Main, BLG Automotive in Bremerhaven, ARS Altmann in Wolnzach, and STVA in Valenton and Paris. As a result of these collaborations, and continuous research on various rail issues, the document was extensively enlarged. The document consists of several parts, namely a historical section that covers railway development in Europe and specific EU countries; a technical section that discusses the different technical issues of the railway (gauges, electrification, controlling and signalling systems, etc.); a section on the liberalisation process in Europe; a section on the key rail players, and a section on logistics services provided by rail.

Mitt. 26 13-28 Dortmund 1992 Verbreitungsmuster der Kriebelmücken (Diptera, Simuliidae) in Bächen entlang der unteren Ruhr, an der Nahtstelle zwischen Mittelgebirge und Flachland Tobias TIMM und Willi JUHL, Essen 1. Einleitung: Die aquatischen Stadien der Kriebelmücken sind in fast jedem Fließgewässer zu finden, von Nichtspezialisten aber nur schwer bis auf Artniveau zu determinieren. Wegen der re­ gionalen Bedeutung als Blutsauger an Weidevieh und Menschen ist die Kriebelmücken­ fauna in verschiedenen Teilen Deutschlands jedoch inzwischen gut erfaßt: So nennen RÜHM und PRÜGEL (1987) für das norddeutsche Tiefland insgesamt 19 Arten, die Mittel­ gebirge Schwarzwald, Rhön, Eifel und Harz weisen zwischen 15 und 25 Arten (WIRTZ et al. 1990), der niederbayerische Raum mit Donaubecken und Bayerischem Wald (SEITZ 1988) insgesamt 31 Arten auf. Auch im niederbergisch-märkischen Hügelland linksseitig der unteren Ruhr sind Kriebel­ mücken bereits als Plageerreger in Erscheinung getreten, so daß im Landkreis Mettmann in den 80er Jahren systematische Bekämpfungsaktionen durchgeführt wurden (SCHWE- DER & TIMM 1989). Es war somit überfällig, das Verbreitungsmuster der Arten entlang der unteren Ruhr zu untersuchen, in einem Raum, wo sich verschiedene geologische, klimati­ sche und anthropogene Einflüsse durchdringen und die Grenze zwischen Region 9 (Zen­ trale Mittelgebirge) und Region 14 (Zentrales Flachland) der Limnofauna Europaea (IL- LIES 1978) verläuft.

The chytrid fungusBatrachochytrium salamandrivorans (Bsal), recently introduced from Asia to Europe, causes mortality in numerous species of salamanders and newts and has led to catastrophic declines and local extinctions of the European fire salamander (Salamandra salamandra) in the Netherlands, Belgium, and Germany. Due to the continu- ous spread of the pathogen, Germany can be considered as the current ‘hotspot’ of Bsal-driven salamander declines.

  • 4.1: South Essen, with Ruhr Reservoir, Agricultural Areas and Woodland (Source: Peter Wieler – Essen Marketing)
    Section 04: Nature and biodiversity 4 A. Current situation Historical, geographical and socioeconomic development factors Due to its fertile loess soil, the countryside of Essen was predominantly used for agriculture until well into the 19th century, and was partly forested. The landscape was dotted with farmsteads and small towns. This cultural landscape can still be seen today, particularly in South Essen ; it is part of a low mountain range (continental region). This is where the Ruhr Valley is located, an important location for the State's network of biotopes, as well as meadowlands that have been registered as a Natura 2000 zone , the Heisinger Ruhraue (Heisingen Ruhr Meadows). (6) Fig.: 4.1: South Essen, with Ruhr reservoir, agricultural areas and woodland (source: Peter Wieler – Essen Marketing) Once coal began to be extracted mechanically after 1800, it was above all the northern area that transformed into an urban industrial zone with isolated areas of greenery and woodland. Streams were converted into wastewater ditches. In the north, only parts of the former cultural landscape remained at the western and eastern city limits, as regional green corridors; these are already part of the North German lowlands (Atlantic region). Geological outliers, special habitats such as exposed Pleistocene riverbeds, mark this remarkable landscape on the periphery of the city. The extensive decommissioning of collieries, factories and railway lines from the 1960s onwards resulted in disused industrial land arising. Despite subsequent use, many of these areas remain, and together with disused industrial land of neighbouring cities, these contribute to the Ruhr Metropolis being home to the greatest diversity of species in North Rhine-Westphalia.
