LAKESHORE-RESTORATION - LANDSCAPE ECOLOGY - LAND USE: ASSESSMENT OF SHORE-SECTIONS, BEING SUITABLE FOR RESTORATION, BY THE EXAMPLE OF LAKE VELENCE (HUNGARY)

The purpose of our study is to develop a decision-preparing assessment method for shore-restoration of medium- (0.5 km(2) 100 km(2)) - and large-sized (>100 km(2)) lakes, utilised primarily for recreational purposes, by the example of a Hungarian study-area (Lake Velence). For detailed assessment of the lakeshore conditions, the legal shoreline was intersected into 100 m long sections; each assessment plot covers 50-50 m from the shoreline both towards the land and the water surface. 9 indicators were defmed and divided into two groups (indicator-systems): landscape ecological conditions and land use features. The lakeshore was evaluated on basis of the assessment indicators by score-system. It was noticed that according to the two indicator-systems, the 3 integral categories involved similar quantity of plots (suitable for restoration: 11 and 16, partially suitable: 53 and 27 and not suitable: 132 and 153 plots). However, the results have made it clear that the plots, being suitable potentially for restoration, can be determined solely by combining the results of the two indicator-systems. Accordingly, just a bit more than 7% of the assessed plots are suitable, or partially suitable for shore-restoration. Though, there are relatively few plots suitable for restoration, it is still very advantageous, that there are also long, continuous sections of more hundred meters (mainly on the south-eastern shore), where all the plots have suitable features for restoration.
