Riparian areas are unique ecosystems that act as natural biofilters. Specifically, they can improve water quality by acting as a microbiological and chemical natural filter. These areas retain the nutrients that are eroded from the agricultural fields. They also store water and materials during flood thus mitigating them. The tree cover can reduce sunlight intensity, creating a "microclimate". This cover can also regulate the temperature of the adjacent aquatic ecosystem and thus control the growth of aquatic vegetation. Because of these services that they offer their conservation is a necessity. This study assessed three streams in different landscape environment specifically in a lowland, semi-mountainous and mountainous areas. The three streams that were assessed were Olynthios River (lowland), Edessaios River (semi-mountainous) and Xerolaki Stream (mountainous), in Centra Macedonia of Greece. The assessed was conducted with the Stream Visual Assessment Protocol (SVAP) that has been used worldwide successfully. The SVAP assess a number of different variables that are summed to provide the final grade of the area that can be characterized as: Excellent, Good, Fair and Poor. In addition, with the use of GIS the adjacent vegetation covers/land-uses were evaluated. Based on the GIS analysis for Olynthios River in the riparian areas there are agricultural fields, forests and semi-natural areas and artificial infrastructures. For the Edessaios River there are also agricultural fields, forests and seminatural areas and artificial infrastructures. Finally, for Xerolaki Stream the riparian areas consisted mainly of forest vegetation and the rest of agricultural areas. In regard to stream substrate, Edessaios River and Xerolaki Stream had primarily gravel and boulders due to the adjacent landscape and the fact the stream slope was steeper. In contract sand was found in high percentages only in the Olynthios River that is in the lowlands and has substantially lower stream slopes. Finally based on the SVAP the Edessaios River is in the best condition, followed by the Olynthios River and finally Xerolaki Stream is in the worst condition. In general, all three rivers/steams have anthropogenic effects that degrade them and measures must be taken for their sustainable management and conservation.
