Abstract

Large number of studies on "landscape fragmentation", were conducted in the literature. Most of them focused on habitat loss (species loss), open space loss, and changes in land use/cover (LULC), and landscape mosaic (landscape pattern/metrics etc.). Fragmentation was one of the most widely used concept amongst these topics that attracts attention due to high urbanization and dramatic changes of the cities. It was emphasized in various articles that fragmentation has adverse impacts on landscape however, it differs in various ways including, quantity of elements, naturalness and ecological values of landscape mosaic. To support this hypothesis, we applied a reference method for measuring fragmentation. In this context, Hedge Network (HN) approach was adopted and applied in lower plain of the ancient Meander River in Aydin Province, Turkey due to its agricultural character. Spontaneous vegetation cover in ditches of irrigated fields are permanent due to the water supply from irrigation system and precipitation in the study area. In this context, hedgerow types along permanent fields were recorded from 15 sampling plots. Thus, this study enabled an enhanced interpretation and biotope/biodiversity based understanding of landscape fragmentation.
