Using integrated remote sensing methods in the Nagyerdő Natura 2000 area
19-24Views:144The more widely use of GIS, remote sensing technology provides appropriate data acquisition and data processing tools to build several national and international biodiversity monitoring system of environmental protection and natur conservation. The ChangeHabitats 2 is a similar international project, which uses airborne hyperspectral and airborne laser scanning (airborne LiDAR) sources beyond traditional data collection methods to build a monitoring system of Natura 2000 habitats. The goal of our research, on one hand, was to separate the most typical species of trees which can be found in the largest coverage in the research plots of Debreceni Nagyerdő Nature Reserve from field and airborne remote sensing data, use image classification that based on spectral and geometry (height) characteristics of the trees. On the other hand our goal was to evaluate the efficient use of the integration of mobilGIS, airborne hyperspectral and airborne LiDAR data collecting methods to complement or substitut of the traditional, field data collecting methods. We used ArcGIS 10.2 and Exelis 5.0 GIS software for data evaluation, in which the mosaicing, the selection of plots and the spectral image processing were carried out.

Fishes protected of Natura 2000 system in Slovakia
9-12Views:69The timely and effective establishment of Natura 2000 network is one of the greatest environmental challenges for the new Member States of the European Union. Slovak Republic is facing this challenge now. By the June 2005, the Government in our country must prepare a list of sites to be included in the Natura network, according to the criteria set up in the Habitat Directive. Natura 2000 sites, according to the specificEUDirectivesconsistofSpecialAreasofConservation(SACs),andSpecialProtectionAreas(SPAs).TheSPAsandtheSACs, the latter selected as Sites of Community Importance (SCIs), will be incorporated into the Natura 2000 network. The problems of proclaiming the system of protected areas of European importance for the Natura 2000 have been one of the major topics of the ichthyological activities in our country in recent years.
For 3 lampreys and 20 fishspeciestheterritoryofpotentialsiteofcommunityinterest(pSCI)hasbeenlimitedandproposed.Theselection of localities and examinations of population state in individual species of fishespresentedintheAnnex(II.,IVandV.)totheCouncilDirective No. 92/43/EEC were carried out in 2003/2004. In total 179 pSCI localities for fishandlampreysinthealpinebiogeographicregion (83) and in the pannonian biogeographic region (96) pSCI in the Slovak republic were selected and limited. The number of pSCI localities selected for individual species is different regards to their distribution within the river net of Slovakia. For example, for species of general distribution, 30 localities pSCI (Misgurnus fossilis, Rhodeus sericeus, Gobio albipinnatus, Barbus barbus) or 35 localities pSCI (Cobitis elongatoides, Barbus peloponnesius), have been proposed, on the contrary, in several species of exclusive distribution as Lampetra planeri - 8, Gobio uranoscopus - 9 and Zingel zingel -12 localities.
The pSCI territory for individual species of the ichthyofauna presented here represents the firststageintheprocessofcreatingtheprotected territory system of European interest Natura 2000 in the territory of the Slovakia for this group of aquatic vertebrates. The list of proposal sites will have to be submitted to the European Commission by the date of Accession.
