The relationships between heterogeneous landscapes and biodiversity have been well investigated and in many cases hu¬man activities have played a significant role in the creation of landscape patterns. In the Dadia – Lefkimi – Soufli Forest National Park (DNP), anthropogenic and natural disturbances during the last century, such as forest fires, uncontrolled logging and extensive livestock grazing created a mosaic of different land-cover categories. However, nowadays natural succession and forest management have altered the mosaic of habitats towards a more homogeneous forest area. More than 70% of the land is now covered with oak and pine forests in either pure or in mixed stands affecting some fauna species depending on heterogeneity and semi-open habitats negatively. Despite this alteration, habitat diversity is one of the main gradients characterizing the landscape structure in Dadia. Although an optimal level of heterogeneity can hardly be determined as it depends on the taxa under consideration, diversity and spatial configuration of landscapes were found to be important drivers of local biodiversity in DNP and must be considered in the management and conservation of the park.

We present an ecological analysis of landbird (Passeriformes, Piciformes, Coraciiformes) distribution in Dadia–Lefkimi– Soufli Forest National Park and suggest measures for their conservation. We conducted two point-count studies, one inside the park (155 points) and the other in an adjoining agricultural zone (75 points) and recorded 120 species of landbirds, including 39 species with an unfavourable conservation status in Europe (SPEC 2 and 3). Vegetation cover and height were the two main environmental gradients affecting bird distribution (Principal Coordinate Analysis). We also identified eight distinct bird habitats (k-means clustering) and found 13 species characterizing them (IndVal procedure). Hence, we proposed a set of selected species to be monitored on a permanent basis (SPEC/typical species). We demonstrated the importance of the buffer zone for landbird conservation rather than the pine-dominated core zone, and more particularly the mosaic sites and forest clearings. Both studies confirmed the unique importance of rural mosaics, thus providing strong arguments against further land re-allotment and agricultural intensification in the broader area around the park.

The main threats to DNP’s principal assets are habitat and landscape homogenization, large-scale fires, the over-development and unwise location of wind-farms around the park, poisoned baits and the aesthetic degradation of landscapes. Impediments to effective management are not only local, but most stem from problems relating to the general system of protected areas in Greece. They are of ecological, administrative, legislative and institutional nature, but there is also a lack of political will to find solutions for them. The principal management and conservation goals for DNP must be to preserve farmland of high ecological value, to arrest forest expansion and to increase the amount of clearings. Others are to preserve old trees and mature stands to ensure optimal nesting conditions for birds of prey and to ensure vulture food resources long-term. To reach these goals, a plan for sustainable local development needs to be developed and the existing legal framework must be amended to support it. Scientific monitoring results must inform all processes. The participation of local communities and authorities is crucial. Local forestry objectives must be revised to match biodiversity conservation needs and promotion of environment-friendly practices in agriculture must be ensured.

Remote sensing now routinely provides environmental information ranging from global to local scales, and geographical information systems provide, among other applications, necessary interfaces to store, analyse and visualise spatial data; increased computational capacities triggered even more such applications. In this chapter, we demonstrate how the combination of landscape approaches, remote sensing and GIS aids conservation and management of biodiversity. We therefore summarise six case studies from Dadia National Park (Dadia NP), in northeastern Greece. The studies aimed at (1) modelling of nesting habitat for a flagship species, (2) evaluation of land-use change, (3) detecting statistical dimensions and spatial patterns of landscape structure, (4) testing the performance of landscape metrics as indicators of biodiversity, (5) developing a GIS approach for a systematic raptor monitoring, and (6) developing a decision-support system to optimise conservation of biodiversity in managed forests.
