Deák József Áron: A Csongrád környéki táj története a XVIII. század végétől napjainkig élőhelytérképek tükrében

Joint to this programme this institute organized the CORINE biotop-map programme in which the author created the 1:50.000 CLC-CET map of Csongrád area (L34-41 c Gauss-Krüger map). In the basemap I gave main CET or CLC category to each biotop patches with Arcview software. (This programme managed to cover the half of the country.) As a further process I created the 1:50.000 summarising map of natural habitats of Csongrád area. This map clearly shows the remained natural areas (forests, grasslands, swamps) and the so called green corridors and the connected natural biotops. In this area not just the river Tisza and river Körös acts as a green corridor but the Vidre-ér too, which could have been a little steam delivering the water of the lakes situated west from Csongrád. The lower part of it was used as a cape and was fished for several hundred years before the reguladon of the riverways. This litde corridor connects worthy grasslands. UnfortunateUy its side branches are cut. The further processed 1:50.000 quaätative map of natural habitats of Csongrád area shows the state of the natural areas. There are 3 categories: natural areas covered by natural, degradated natural or landscape-alien vegetation. In the first case the natural friendly use is recommended according to the type of the biotop. In the second case the way of using should be changed (for example the area is undergrazed and a lot of Eleagnus angustifolia tree appeared or these areas are fallows, so we must help the vegetation to renaturalize itself: sometimes let it on its way, but sometimes with grazing or mowing. They could be forests mixed with non-nadve species (so the non-native trees must be cut off). As we could see these works are good not just to use it for nature conservation but to get a full picture on the present and past feature of the landscape. Our datas and aims determine which category-system and scale to choose (for detailed searches m-ANÉR, for comprehensive and landscape historical purposes CLC-CET is recommended). These maps can be a data base for monitoring and planing the landscape and rural development. They show the areal natural potential of rural ecotourism and helps the environmental education at planning educational footpathes. They help not just the scientific experts but the policy makers and land-users to make optimal decisions and do a really sustainable landscape use. References Bellon, T.
