Fish-Based Assessment Of The Ecological Status Of The Kis-Balaton–Balaton Reservoir–Lake System, Hungary

GIS-based approach to find the suitable sites for surface flow constructed wetlands was employed for the Lithuanian river basins with low ecological status. According to the nature of the analysed criteria the flowchart consists of two phases. Criteria used include hydrographical network, soil properties, terrain features, land use, etc. Some of them have strictly defined values (constraints), and other ranges within certain limits (factors). Limited criteria were analysed using rejection principle and influencing factors using proximity analysis and overlay methods. Selecting the potential sites using standard GIS analysis tools there was estimated about 3286 sites for possible wetlands with the mean area of inflow basin about 4 km2 in the basins of water bodies at risk.

Terrestrial Biodiversity

With the exponential rise of human activities in the past decades, majority of studies conducted in Taal Volcano Protected Landscape (TVPL) are geared towards the conservation and preservation of Lake Taal’s remaining biodiversity. However, the current structure and assemblage of its terrestrial biotic communities remain relatively unstudied. In this study, we conducted biodiversity censuses in the four sites in TVPL to provide baseline information regarding the community structure of the selected study sites. Comparison of the plant diversity in Taal Volcano Crater Island and Romandan Falls within the forested areas of Mataas na Kahoy, Batangas reveal that both sites support remarkably different vegetation, with the former supporting a smaller floral diversity. The fairly small number of animal samples present difficulty in providing conclusive findings to the wildlife structure of the two study sites. However, the presence of 11 animal species exhibit valuable results in determining the ecological status of TVPL. It is deduced that several ecological barriers exist between the sites, which is attributed to their unique terrestrial biota.

Technical Operation

The article analyzes the current state of the irrigation and drainage systems of the Ryazan region. It is shown that the lack of technical operation of the drainage network led to its failure and failure to perform its functions. Irrigation, in spite of the fact that it gives stability in the years of droughts due to aging and the dismantling of machinery and equipment is not carried out. It is shown that for the reconstruction and / or modernization of irrigation and drainage systems it is necessary on the basis of inventory to determine the environmentally optimal and economically viable systems, their parts and structures that require rehabilitation, reconstruction and / or modernization. The decision to reconstruct may include not only the ameliorative system as a whole, but also some part of it, for example, a canal, pipeline or a separate hydraulic structure, taking into account the justification of economic feasibility. In dry periods, for the Meshcherskaya lowland and areas with peat soils, it is necessary to provide for land-reclamation systems for dual regulation of soil moisture, which reduces the possibility of peat ignition and the spread of fire. It should be borne in mind that the reconstruction of land-reclamation systems has its specific features, which include: socio-economic (increasing the productivity of agricultural land, obtaining additional income, creating modern infrastructure, increasing employment, living conditions, labor, etc.) ; ecological (creation of cultural landscapes, ensuring their ecological sustainability, prevention of land degradation processes, improvement of recreational conditions, elimination of waterlogging, flooding, salinization, erosion, etc.). Reclamation activities are carried out in compliance with the requirements of land, water, forestry legislation of the Russian Federation, as well as the legislation of the Russian Federation on the protection of the environment, on the subsurface, on the plant world and on the animal world.
