Landscape Heterogeneity In Bollige Kerkinna
1. Introduction
The question of definition and measurement of landscape complexity is essential, because it lies at the heart of any attempt to quantify and monitor large databases of landscape characteristics, through field observations, remote sensing, or through any other conventional means of collecting such data.
Yet, no unique measure of landscape complexity has been established so far and the problem of defining landscape complexity remains open.
The question of spatial landscape complexity (itself being a component of landscape complexity) is a long-standing one. Pielou (1975), as well as Forman and Godron (1986), described ways of discretizing the landscape's “structure” (its patches the matrix and their spatial interrelationships) and obtained relative measures of information and entropy from these discretizations (Forman, 1995), but spatial/structural landscape complexity is different a notion than landscape heterogeneity (Papadimitriou, 2002; Ryan et al, 2007).
A number of studies on ecological and landscape (ecological) complexity have been carried out since the 1990s and particularly over the last years (Maurer, 1999; Ascher, 2001; …show more content…
For this reason, Kerkini has been the subject of several applied ecological and environmental studies over the last years. The increased spatial/structural landscape complexity in the area surrounding the lake is an indicator of increased habitat fragmentation. This has been documented (Bell et al, 2007; Chelazzi et al, 2007) and is also related to local socio-economic activities causing further degradation of the ecosystems in that area (Daoutopoulos and Pyrovetsi, 1990; Ogelthorpe and Miliadou, 2000; Pyrovetsi and Daoutopoulos, 1999). Part of a land cover map of the region north of Kerkini lake was studied here, as shown in figure 2 (scale
