Mediterranean islands are characterized by high biodiversity and cultural value. As the human demand for natural resources increases, the need for assessing the future landscape is prerequisite. This study aimed to simulate the future landscape composition and structure of the Ionian Islands (Western Greece). To do so, we integrated the Future Land Use Model and Markov Chain analysis, taking into consideration fifteen socio-environmental predictors. The results showed that the landscape of the Ionian Islands is expected to develop into two major patterns. The first pattern refers to the expected increase of forests and scrublands, shaping a homogenous landscape. Whereas, the second pattern reveals an expected degradation of natural vegetation, shaping a highly fragmented landscape. In all circumstances, the built-up areas are anticipated to extend, mainly near to touristic hot-spots. This study demonstrated that contemporary spatial simulation approaches, along with various socio-environmental factors offer an important tool for effective landscape management.

Mediterranean islands are widely recognized as biodiversity hotspots, with a long history of human activities shaping multi-functional landscapes. Socioeconomic and environmental factors are among the most important factors driving the creation of diverse landscapes, with a high supply of ecosystem services (ES). However, these factors, along with climate change, could also have irreversible consequences on local ecosystems. Thus, this study aimed to reveal the importance of socio-ecological factors in shaping ES bundles to manage natural resources efficiently and enhance human well-being. Using the Ionian Islands as a case study, we explored the relationships among multiple ES, including their supply and demand indicators. We identified bundles of ES to distinguish regions in which supply and demand exhibit different characteristics. An ensemble machine learning method (Random Forest - RF) was used to identify the most important socio-ecological variables out of 17 tested that contribute to ES bundles. Our results produced five bundles of ES supply and six bundles of ES demand. The most important variables for the distribution of ES supply bundles were landscape heterogeneity, elevation, slope, landscape connectivity, and population. In comparison, variables representing elevation, slope, and population were among the most important variables contributing to ES demand bundles. RF exhibited both good classification and predictability, which was supported by the accuracy measures. Our findings demonstrated that research on ES should account for underlying socio-ecological drivers that influence the supply and demand of ES to improve our understanding of the possible impacts of future management decisions regarding the diverse Mediterranean landscapes of the Ionian Islands.

Capercaillie is a species of particular conservation importance for Europe due to the observed population decline in various parts of its distribution. In the current study, the environmental and habitat requirements of the species are investigated at the southernmost range of its European distribution (Rodopi Mountain-Range National Park, northern Greece) using a set of 95 observations of species presence and a maximum-entropy (MaxEnt) Modeling approach. A bioclimatic dataset derived from the Bioclim open source database and a set of environmental variables, mainly forest land-cover types and topographical variables, were employed to explain the current distribution of the species and to delineate potentially suitable areas for its distribution. The best scale per environmental variable was chosen among three different spatial scales (10 ha, 100 ha and 500 ha), in order to build a multiscale environmental model. According to our results, the species demonstrated a very narrow niche which is determined primarily by bioclimatic factors while a number of habitat requirements within a strict bioclimatic zone where also identified. It requires wet areas with mean summer temperature not exceeding 10 °C, which are only found at the higher altitudes of the national park. Α strong tendency was also found for capercaillies to inhabit forest stands of norway spruce (Picea abies) with a minimum cover of 10% at an intermediate scale of 100 ha, followed at a larger scale i.e. 500 ha by pure beech (Fagus spp.) forests or mixed with pines (Pinus spp.), where optimum tree density ranges from 50% to 80%. Bioclimatic and environmental presence-prediction maps were reclassified in four suitability classes (marginal, sub-optimal, optimal), based on three Maxent thresholds (Minimum Training Presence, Fixed Cumulative Value 5 and Value 10). Monitoring the marginal climatic zone for the species and ensuring suitable habitats within it is the key for the species conservation in its southernmost part of its distribution.

To manage multiple ecosystem services (ES) effectively, it is essential to understand how the dynamics of ES maintain healthy ecosystems to avoid potential negative impacts on human well-being in the context of sustainable development. In particular, the Ionian Islands in the central Mediterranean are characterized by high natural, ecological, and recreational value; however, the intensification of human activities over time has resulted in the loss of natural ecosystems, which might have negatively impacted ES. Here, we aimed to assess and understand the spatiotemporal dynamics of ES supply and how these components interact across the Ionian Islands to optimize future ES provision and mitigate current trade-offs. We quantified multiple ecosystem services and analyzed their interactions at a temporal scale across the four prefectures of the Ionian Islands. Seven ES were quantified covering all three ES sections (provisioning, regulating and maintenance, and cultural) of the Common International Classification of Ecosystem Services (CICES). ES interactions were investigated by analyzing ES relationships, identifying ES bundles (sets of ES that repeatedly occur together across space and time), and specifying ES occurrence within bundles. The three ES groups exhibited similar patterns on some islands, but differed on islands with areas of high recreation in parallel to low provisioning and regulating ES. Temporal variations showed both stability and changes to the supply of ES, as well as in the interactions among them. Different patterns among the islands were caused by the degree of mixing between natural vegetation and olive orchards. This study identified seven ES bundles that had distinct compositions and magnitudes, with both unique and common bundles being found among the islands. The olive grove bundle delivered the most ES, while the non-vegetated bundle delivered negligible amounts of ES. Spatial and temporal variation in ES appear to be determined by agriculture, land abandonment, and increasing tourism, as well as the occurrence of fires. Knowledge about the spatial dynamics and interactions among ES could provide information for stakeholders and decision-making processes to develop appropriate sustainable management of the ecosystems on the Ionian Islands to secure ecological, social, and economic resilience.

Mediterranean islands contain heterogeneous landscapes, resulting from the complex interactions between natural and anthropogenic processes, and have significant ecological and conservation importance. They are vulnerable systems to global change and the monitoring of changes, induced by the interacting environmental drivers, is of particular importance for applying a sustainable management regime. The aim of this study was to detect and analyze the landscape dynamics and changes in landscape composition over a 30-year period on the Ionian Islands of Western Greece. State-of-the-art object-oriented image analysis on freely available remote sensing data such as Landsat images was employed achieving final mapping products with high spatial and thematic accuracy (over than 85%), and a transferable classification scheme. The main drivers of environmental change are tourism and associated activities, wildfires and livestock breeding which act in different ways and intensities within and between the islands. The repopulation of those islands, after a period of significant depopulation from the 1940s to the 1980s, and the boom of tourism since the mid-1970s prevented further land abandonment and the recultivation of abandoned land which indicates that tourism and agriculture can be complementary rather than competing economic sectors. Despite the significant increase of tourism, a general trend was observed towards increasing cover of high-density vegetation formations, such as shrublands and forests. At the same time, wildfires, which are in some cases associated with livestock breeding, continue to be an important vegetation degradation factor preventing further ecosystem recovery on the study islands.

Raptors are emblematic species of high conservation value and significant ecological role. Their conservation is of particular importance and it relies on the conservation of their habitats and the constant monitoring of their dynamics. In the current study we investigate land cover changes over the period 2001–2011, in one of the most important reserves for raptor conservation in Europe, the Dadia-Lefkimi-Soufli Forest National Park. Very high and high spatial resolution satellite data were integrated in a single analysis, in order to exploit the high spatial accuracy of the former and the high temporal and spectral resolution of the latter. The results suggest that the applied method increases the overall accuracy of the mapping product from 73% to 89%, providing a tool to land managers and conservationists to study landscape dynamics and guide wildlife management. The analysis of land use changes revealed that wildfires of high intensity and large extent, constitute a new threat for the ecological integrity of the reserve. If the currently observed trend of wildfire behavior in Greece and southern Europe continues it is likely to affect the core zones of forest reserve, which consist primarily by dense forests with high fuel load, with detrimental effects for wildlife. The most important land cover change observed is the significant reduction of open areas, which form the main hunting areas for raptors. Open areas appear to be encroached by forest, leading to loss of heterogeneity which has been reported to be associated with high biodiversity. The results reveal the need for more active management measures that would decrease the risk of large stand replacing fires and would ensure a suitable landscape structure for raptors.

The use of satellite data has been widely applied to provide a cost-effective mean to analyse land cover changes over large geographic regions. The aim of this study was the multi-temporal change analysis of vegetation over the last 30 years, using freely available remote sensing data in three steps in Ilia Prefecture, Greece. In the first step, four vegetation indices were adopted to analyse the dynamic change of vegetation. At the second step, the investigation of the vegetation density changes was succeeded through thematic change detection techniques, and lastly, at the third step, a comprehensive change detection method (CCDM) was applied for mapping biomass progress/regress. Finally, after the catastrophic mega-fire of 2007 in Ilia, a change analysis of four vegetation indices focused on this affected region was implemented to investigate the vegetation restoration. Although some spatial changes of vegetation cover were observed during the study period, the state of biomass either improved or remained constant through time, demonstrating the high potential of Mediterranean ecosystems to recover after disturbance events.

Harnessing wind energy is seen as an environmentally friendly strategy to combat climate change. However, adverse environmental impacts have come to light for species that are prone to collision with wind turbine blades, such as vultures, leading to a conflict between wind energy industry and conservation. Our study area epitomized such a conflict, containing the only population of cinereous vultures in south-eastern Europe while also being the location for substantial existing and planned wind farms. We used long-term remote telemetry data to produce a species-specific sensitivity map for guiding wind energy development and to estimate vulture collision mortality due to currently operating wind farms. Most operational wind farms were in the population core area and in the highest priority areas for vulture conservation. Collision mortality due to the thirteen operating wind farms was estimated by combining global position system (GPS) telemetry data on vulture space use with a collision risk model (CRM). Estimated mortality varied greatly according to the CRM's ‘avoidance rate’. Under the most likely avoidance rates annual predicted collision mortality was 5–11% of the population, creating risk of population decline. Collision mortality was expected almost exclusively in the population core area, rendering further future development plans there severely problematic for vulture population persistence. Our sensitivity map, as a conservation prioritization system, offered a spatially explicit solution to the conflict between wind energy development and vulture conservation. Combining spatial use models derived from telemetry data with collision mortality models offers a novel conservation tool for evaluating large scale wind energy development proposals.

The current study took place at Natura 2000 areas in Ionian Islands, specifically at Zakynthos and Strofades. Both islands have a significant natural and cultural heritage and constitute part of the Natura 2000 Network. Zakynthos is protected for its biodiversity and its landscape and the Strofades islands belong to the National Marine Park of Zakynthos. The forest character of both areas constitutes a common base for a proposal for their alternative and sustainable development. Because of recurrent fires, the currently occurring degradation of woodland area at the west coast of Zakynthos demonstrates the importance of supporting and promoting natural and cultural heritage of the area, so as to ensure its protection and conservation, as well as its sustainable environmental and socio-economic development. Regarding Strofades, it constitutes a significant sequestered ecosystem, an important habitat for different species, hosting the only forest in Greece with Juniperus phoenicea. The present study mapped and recorded the environmental and cultural characteristics of Zakynthos and Strofades (ecosystems, biodiversity, landscape, soundscape, culture), to propose a compiled model for an alternative sustainable development.

Migrating raptors and black storks (Ciconia nigra) were studied in Dadia National Park, Greece, during spring 2003–2005. Vantage points and transects were used to evaluate magnitude, phenology, local variation and direction. We observed 23 species and 2030 individuals, including 715 common buzzards (Buteo buteo), 547 black storks and 136 short-toed eagles (Circaetus gallicus). Species-specific migration peaks were detected, starting in the second half of March, e.g. common buzzard, short-toed eagle, black stork, and ending early May, e.g. Levant sparrowhawk (Accipiter brevipes), red-footed falcon (Falco vespertinus), honey buzzard (Pernis apivorus). Most raptors were observed in the Evros valley, which may function as a migration corridor. The average direction of passing raptors was north. Species’ proportions and phenology in the study area were similar to those in neighbouring Bosphorus and Marmara Flyways. Further migration monitoring should be established in the area, which will provide important information not least to inform wind farm development location.

We evaluated how fire impacts the ecological coherence of Aleppo pine forests and their biodiversity over a 40-year period. The study area forms part of an insular ecosystem of Zakynthos Island (Zante) in western Greece, which forms part of the Ionian Islands. Post-fire effects were studied for both plant and bird diversity at 20 sampling plots, using stratified random sampling, during the summer of 2012. The plots were selected based on the frequency of burning since the 1970s. Sites were categorized as: 1) no burning for >40 years, 2) burnt once in the 1970s, 3) burnt twice, first in the 1970s and again in 2000–2010, 4) burnt three times, first in the 1970s, and twice more in 2000–2010, and 5) burnt four times, first in the1970s, twice more in 2000–2010, and again in 2011. A total of 79 plant species and 26 bird species were recorded at the studied sites. One-way ANOVA analysis showed that fire intensity has a significant impact on alpha floristic diversity. Average plant species richness at sites that burned in 2011 was significantly higher than in those that burned in the 1970s. Detected differences in bird species richness were not significant; however, more species were documented in the forested habitats (unburnt for >40 years, and burnt in the 1970s). The highest Jaccard similarity index was observed between the sites that had not burned for more than 40 years and the sites that burned in the 1970s. The lowest floristic similarity to non-burnt sites was observed between the recently burnt sites in 2011 and the sites that burned in the 1970s. The lowest bird similarity was detected between recently burnt sites in 2011 and sites that had not burned for more than 40 years. DCA ordination showed the presence of a clear fire gradient, from intensively burnt open sites to non-burnt forest sites. We suggest that fire is essential to maintain biodiversity in Aleppo pine forests, but only at intermediate frequency.

Environmental and isolation variables relating to abundance of breeding amphibians, species richness and community structure at different spatial scales were examined in the Dadia-Lefkimi-Soufli Forest National Park, Evros, Greece. Logistic regression and a generalized linear model were used to relate several habitat characteristics to species occurrence and species richness. The community structure responses to breeding-pond features were examined at four spatial scales using canonical correspondence analysis (CCA). The richest communities live in low-altitude ponds, with stony or clay bottoms, high solar exposure and abundant submerged and floating vegetation. The CCA models were significant (p < 0.005) and revealed the influence of altitude, percentage of field and broadleaf forest coverage, and number of water bodies on amphibian species assemblages at all four spatial scales. There is a specific need for holistic management of amphibians that will consider habitat connectivity, particularly between aquatic and terrestrial habitats, at a larger, more interconnected scale.
