Environmental Assessment of Central European Floodplain Forests: A Case Study from the Morava River Alluvium

Abstract

Areas subject to little anthropogenic impact and with preserved river dynamics are very rare in the floodplains of large European rivers [7][8][9]. These environmentally valuable territories are usually categorized as different forms of protected areas. Particularly due to the establishment of the Natura 2000 network of nature protection areas, the number of floodplain forests thus protected in Europe has been gradually increasing. In the context of environmental assessment of Natura 2000 sites, environmental assessment of the level of natural habitat conservation appears to be a potential decision support tool. This paper assesses the efficiency of the Natura 2000 European Network in the biodiversity conservation of Central European floodplain forest habitats on the ecosystem level of an entire river basin (Morava River basin, Czech Republic). In order to express the efficiency of natural habitat conservation, our paper uses the nature conservation efficiency index, which is calculated in the GIS environment based on an environmental analysis of data obtained through natural habitat mapping in the Czech Republic, conducted in 2001-2004 as part of the conservation objectives of Natura 2000. Environmental analysis results show that the conservation efficiency of the Natura 2000 network in territorial conservation of floodplain forests in the study area of the Morava River floodplain is approximately six times as high (NCEIEU = 0.067) as the efficiency of the Czech national network of protected areas (NCEICZ = 0.017). The paper also highlights the importance of detailed habitat mapping for environmental landscape studies.

Evaluation of Replication Mechanisms on Selected Database Systems

“…Practically, these replication mechanisms have been primarily used for these research tasks [29][30][31]. The purpose of deployment of replication mechanisms for these research tasks was using an extensive spatial dataset; hence, the benefits of a distributed database network for load balancing between the master database (to write changes) and slave database (for solving analytical problems) were utilized [5].…”

Robust Strategic Weight Manipulation Model with an Application to Environmental Assessment

“…Accordingly, the concept of "clear waters and lush mountains are mountains of gold and silver" has been put forward by the Chinese government as a guideline for environmental governance. In the process of environmental governance, the design of environmental assessment [2][3][4][5][6] is particularly important in order to effectively evaluate the efficiency of environmental governance. Environmental assessment encourages the consideration of environmental factors in planning and decision-making, ultimately leading to more environmentally compatible production activities.…”

Changes in soil properties due to land reclamation and climate change in South Moravian floodplain forest

“…Lately, the disconnection between the Dyje River level and the water regime was documented (Klimo et al 1999;Klimo & Hager 2001;Prax 2004;Menšík et al 2015). Several wetland restoration projects were approved to become financed through the EU Environment Programme to protect the area (Penka et al 1985(Penka et al , 1991Klimo et al 1999;Klimo & Hager 2001;Hřib & Kordiovský 2004;Filippovová & Pohanka 2019). The restoration took two courses -controlled flooding and restoration of water channels.…”
