Management of Biological Invasions | Year: 2017

Invasive alien species (IAS) are a significant and growing problem worldwide. In Europe, some aspects of IAS have been addressed through existing legal instruments, but these are far from sufficient to tackle the problem comprehensively. The FINS II Conference considered the relevance of Top 20 IAS issues (Top 10 threats and opportunities) for Europe determined at the 1st Freshwater Invasiveness – Networking for Strategy (FINS I) conference held in Ireland in 2013. Using a similar format of sequential group voting, threats from FINS I (lack of funding, of awareness and education; poor communication) and several new threats (lack of lead agencies, of standardized management and of common approach; insufficient monitoring and management on private property) were identified by 80 academics, applied scientists, policy makers and stakeholders from 14 EU and three non-EU countries (including 10 invited speakers) during four workshop break-out sessions (legislation remit in both EU/non-EU countries; best management and biosecurity practice for control; data management and early warning; pathways of introductions and citizen science). Identified opportunities include improved cooperation and communication, education and leadership to enhance public awareness and stakeholder participation, systems establishment for early detection, rapid response, monitoring and management of IAS using standardised methods of data collection, storage and usage. The sets of threats and opportunities identified underline the importance of international cooperation on IAS issues in communication, education and funding as priorities, as well as in standardization of legislation, control methods and best practise of research. © 2017 The Author(s) and 2017 REABIC.

Freshwater Crayfish | Year: 2014

Despite the knowledge on the mechanisms causing population declines in European crayfish stocks (e.g., crayfish plague, alien species, habitat loss), the assessment and quantification of their threats have received insufficient attention. We aimed to assess the potential range of indigenous (ICS) and nonindigenous crayfish species (NICS) in Carinthia (Austria) by developing habitat suitability models of the native Astacus astacus and Austropotamobius torrentium, as well as the invasive Pacifastacus leniusculus. Based on landscape elements, we defined the level of fragmentation in catchments having ICS and NICS. This information was used, together with spatial distances to potentially plague carrying NICS, roads and settlements, to calculate a threat index evaluating the endangerment of each remaining ICS population (including Austropotamobius pallipes). We found A. torrentium had the widest potential distribution, while the potential range of A. astacus and P. leniusculus was mainly overlapping. Riverine and lacustrine landscapes with ICS and NICS occurrence were highly fragmented and logistic regression models showed that extinct ICS populations were positively associated with settlements, but negatively so to barriers. Existing stocks of Austropotamobius were less endangered than those of A. astacus since populations of the former are located at higher elevations resulting with lower human impacts. In contrast, P. leniusculus was associated with human infrastructures in the lowlands. The threat index identified the most endangered ICS populations. The tools and analyses applied here at the landscape level are helpful to establish catchment-based conservation plans for threatened ICS, and to predict the further spread of NICS.

This example of the Lower Salzach's self-forming widening without bank reinforcements in the hinterland illustrates the complete process from creating a general concept of morphology- based measures, to planning and obtaining the necessary authorization, to the implementation and the first highly promising experiences from a hydrological year marked by a flood with a return period of once in 30 years. The idea of doing without state-of-the-art bank reinforcement techniques was a bold step on the part of the Bavarian and Austrian water management authorities. This not only serves the environment, but also saves the costs of building new bank reinforcements for the purpose of flood control that are normally necessary when rivers are widened. Self-forming widening is part of an overall concept employed to help the Lower Salzach gradually recover from its eroded state to a revitalized, morphologically dynamic and balanced one. It also creates a region that can simultaneously serve as an essential biotope and as a rest and recreation area for the local populace. © Springer-Verlag 2012.

Vegetation succession on glacier forelands has been well-studied. However, most of the studies investigated only one or few glacier forelands. We studied regional variations in vegetation succession on 16 glacier forelands in the European Alps. To improve our understanding of how vegetation succession is regulated by environmental conditions, we took edaphic and climatic factors into account. We collected vegetation data in three stages (early; middle; late) along a successional gradient on glacier forelands in the Eastern and Western European Alps. The progressions of species richness, vegetation cover and composition during primary succession were compared between these two regions. In addition, the effects of climatic and edaphic factors and grazing were tested. Our results reveal that the vegetation from the early stage did not differ between the regions and different elevations. With progressing time, and especially in the late successional stage, several vegetation differences emerged. The forelands of the Western Alps already developed to open shrubland, while the forelands of the Eastern Alps so far only developed toward grassland. Surprisingly, these differences cannot be explained by different precipitation amounts, but possibly by different regional species pools and elevations of the treelines. We conclude that a complex of edaphic factors closely related to terrain age, regional differences in the species pool, and the different elevation of the treeline in the eastern and western Alps mostly influenced later stages of primary succession on glacier forelands. © 2016 Swiss Botanical Society

For a river reach of the Lower Salzach River at the border between Germany and Austria an option analysis for a rehabilitation is currently being conducted concerning water engineering as well as freshwater-ecological measures. In addition to three options including only river engineering components, two further alternatives also offer an energy recovery model. In order to evaluate the different options, their impact is analysed in reference to clearly defined criteria. The findings will provide the basis for a decision for one alternative.

In a nature conservation project titled 'Baseline mapping of habitats and species of European Community interest in Austria' (2010 to 2013), the distributions of 40 species and habitat types listed in Annexes I, II and IV of the EU Habitats Directive were updated based on existing data and extensive area inspection. With the installation and initial entry of sampling plots for selected habitats and species, the foundation for future Article 11 monitoring has been laid. A specific monitoring design was implemented. As a central data management platform, the WebGIS-Tool EMaRT was developed, a multi-user capable system for visualization, data capture and survey tailored to Habitats Directive Article 11 monitoring and Article 17 reporting in Austria.

The steps for implementing the EU Floods Directive are delineated in the Water Management Act (Wasserrechtsgesetz). From March to September 2014, the Austrian states were given six months time to prepare flood risk management plans on the basis of a federal draft plan. Suitable plans were to be created for all areas subject to potentially significant flood risks. The harmonization of all levels (federal, state and regional) concerning the overarching subject „Flood Risk Management,“ as well as the comprehensive networking and coordination of the responsible and affected offices, is essential in order to allow integrative planning. The respective states employed a variety of different approaches. In Styria and Carinthia a detailed methodology for the process was developed that is based on the intensive involvement of all responsible and affected offices at an early stage. Though the actual implementation varied somewhat between the two states, the flood risk management plans prepared in Styria and Carinthia alike yielded both considerable acceptance and improved quality. © 2015, Springer-Verlag Wien.

Concept for an impact regulation for Austria - Practical tool, to be implemented voluntarily For the first time a nationwide standard procedure for the impact regulation according to nature conservation has been suggested for Austria. It is to be introduced on a voluntary base. It aims to improve the standard of nature conservation procedures, to advance planning certainty and legal security, and to make the process more fair and transparent. he standard procedure mainly emphasizes the differences between equalization (“Ausgleich”) and substitution (“Ersatz”) and also integrates them into the calculation procedure. In this regard and due to the fact that it considers temporary interferences the suggested approach makes an important contribution in the “family” of calculation methods and guidelines. © 2016, Verlag Eugen Ulmer.

Over the last 20 years a flood control strategy has been pursued on the Upper Drau in Carinthia (Austria), which is not set on "hard" control structures but natural water dynamics and synergies with nature conservation and recreational use. The basis for this is a water development concept from 1992, one of the first of its kind in Austria. Meanwhile, with financial support from the European Unions' LIFE-Natur-Fonds, around a quarter of the Upper Drau has been revitalised and the river together with its riparian zone has been declared a European Protected Area.
