Environmental DNA as Early Warning for Alien Species in Mediterranean Coastal Lagoons: Implications for Conservation and Management

Non-indigenous species (NIS) introduction notoriously threatens the Mediterranean Sea. In addition, Mediterranean coastal lagoons play a crucial role as nurseries for marine species, which new NIS arrivals can threaten. Therefore, monitoring and early warning of NIS presence is essential in preserving biodiversity. An innovative technique for rapid and accurate species identification and biodiversity screening is the application of environmental DNA (eDNA) metabarcoding. In this research, different Penaeidae (Arthropoda, Crustacea, Decapoda) NIS specimens were collected from a Mediterranean coastal lagoon after an early warning about a potentially invasive NIS arising from next-generation sequencing data. DNA barcoding of the DNA extracted from tissue samples and amplified with specifically designed primer pairs led to the recognition of Penaeus aztecus in this NATURA 2000 protected ecosystem for the first time. DNA barcoding from DNA isolated from the water where the living specimens were stored further validated the possibility of identifying P. aztecus starting from eDNA. This approach demonstrated the validity of environmental DNA analysis in the early screening of potentially invasive NIS presence in Mediterranean protected areas and ecosystems. This work describes an applicative example of the efficacy in improving the biomonitoring of lagoon ecosystems using molecular tools and it represents a guideline for the validation of eDNA metabarcoding data for the presence of potentially invasive species.

Standardized transect walks outperform pan traps in assessing wild bee community in a Mediterranean protected area (Asinara National Park, Italy)

The decline of pollinator insects in various parts of the world has increased the interest in studies on bee sampling. Because pollinator management and conservation policies depend on data representing their communities, knowledge of the systematic bias of sampling methods in relation to surrounding habitat is fundamental. This study examined the performance of standardized transect walks and colored pan traps considering differences in bee species richness, diversity, and composition, and the potential bias due to a different availability of floral sources throughout seasons. The study was conducted in a minor outlying island (Asinara, Italy), a natural park characterized by the prevalence of natural or semi-natural habitats and an Oceanic Pluviseasonal Mediterranean bioclimate. We found that transect and pan trap methods reflected different bee communities based on taxonomic families, genera, and species. In general, the transect method captured more varied samples than pan traps, despite the significantly lower number of individuals captured on transects. Moreover, pan traps captured more bees as floral abundance decreased, whereas transects showed greater bee abundance, richness, and diversity with increasing floral resource availability. In addition, 18 species out of the 68 observed in total were caught exclusively with pan traps, especially in July–October, when transect catches decreased due to substantial bloom reduction. Therefore, alternating the two methods according to season (i.e., transect in late winter-spring and pan trap in summer-autumn) might be the most suitable trade-off to obtain a better representation of the bee community by limiting sampling efforts and the negative impact on bee fauna.

Is Joint Management between Conservationists and Farmers Sustainable and Biodiversity-friendly? A Ten-year Study in Residual Grasslands of a Protected Area.

In recent decades, there has been a discernible reduction in temperate and Mediterranean grasslands with consequences on the decline of biodiversity and landscape heterogeneity. When this decline is due to agricultural abandonment, a renewed joint management, combining bush clearing by conservationists and grazing by farmers, should favor the maintenance of grasslands, their protected habitats and species and forage production. Rainfall irregularity explains part of the variation of these parameters. To verify these hypotheses, we conduct a comprehensive, multi-scale, multi-taxa study over a ten-year period in a Mediterranean protected area. At the regional scale, experimental plots in which this joint management was implemented are representative of residual managed grasslands of the protected area. At the mesoscale, rainfall irregularity is the main factor explaining inter-annual differences in the biomass of open landscapes, while fauna depends on management, tree cover and trophic resources. At the local scale, in a representative experimental plot, clearing had an immediate negative impact on plant richness and bird and positive on forage. Over a decade, plant biodiversity increased while forage, specialist plants and bird maintained, despite the regrowth of bush. Drought had a negative impact on richness, plant and forage abundance and phenological asynchrony on butterflies. In conclusion, joint management has positive, neutral and negative impacts to be considered before implementing this strategy. This long-term monitoring study draws important lessons for designing a sustainable management of grasslands under abandonment and irregular climate, that should be applied in temperate and Mediterranean regions that are increasingly vulnerable to these trends.

Oceanographic and anthropogenic variables driving marine litter distribution in Mediterranean protected areas: Extensive field data supported by forecasting modelling

Marine litter concentration in the Mediterranean Sea is strongly influenced both by anthropogenic pressures and hydrodynamic factors that locally characterise the basin. Within the Plastic Busters MPAs (Marine Protected Areas) Interreg Mediterranean Project, a comprehensive assessment of floating macro- and microlitter in the Pelagos Sanctuary and the Tuscan Archipelago National Park was performed. An innovative multilevel experimental design has been planned ad-hoc according to a litter provisional distribution model, harmonising and implementing the current sampling methodologies. The simultaneous presence of floating macro- and microlitter items and the potential influences of environmental and anthropogenic factors affecting litter distribution have been evaluated to identify hotspot accumulation areas representing a major hazard for marine species. A total of 273 monitoring transects of floating macrolitter and 141 manta trawl samples were collected in the study areas to evaluate the abundance and composition of marine litter. High mean concentrations of floating macrolitter (399 items/km2) and microplastics (259,490 items/km2) have been found in the facing waters of the Gulf of La Spezia and Tuscan Archipelago National Park as well in the Genova canyon and Janua seamount area. Accordingly, strong litter inputs were identified to originate from the mainland and accumulate in coastal waters within 10–15 nautical miles. Harbours and riverine outfalls contribute significantly to plastic pollution representing the main sources of contamination as well as areas with warmer waters and weak oceanographic features that could facilitate its accumulation. The results achieved may indicate a potentially threatening trend of litter accumulation that may pose a serious risk to the Pelagos Sanctuary biodiversity and provide further indications for dealing with plastic pollution in protected areas, facilitating future management recommendations and mitigation actions in these fragile marines and coastal environments.

Interactions between carnivore species: limited spatiotemporal partitioning between apex predator and smaller carnivores in a Mediterranean protected area

BackgroundThere is need of information on ecological interactions that keystone species such as apex predators establish in ecosystems recently recolonised. Interactions among carnivore species have the potential to influence community-level processes, with consequences for ecosystem dynamics. Although avoidance of apex predators by smaller carnivores has been reported, there is increasing evidence that the potential for competitive-to-facilitative interactions is context-dependent. In a protected area recently recolonised by the wolf Canis lupus and hosting abundant wild prey (3 ungulate species, 20–30 individuals/km2, together), we used 5-year food habit analyses and 3-year camera trapping to (i) investigate the role of mesocarnivores (4 species) in the wolf diet; (ii) test for temporal, spatial, and fine-scale spatiotemporal association between mesocarnivores and the wolf.ResultsWolf diet was dominated by large herbivores (86% occurrences, N = 2201 scats), with mesocarnivores occurring in 2% scats. We collected 12,808 carnivore detections over > 19,000 camera trapping days. We found substantial (i.e., generally ≥ 0.75, 0–1 scale) temporal overlap between mesocarnivores—in particular red fox—and the wolf, with no support for negative temporal or spatial associations between mesocarnivore and wolf detection rates. All the species were nocturnal/crepuscular and results suggested a minor role of human activity in modifying interspecific spatiotemporal partitioning.ConclusionsResults suggest that the local great availability of large prey to wolves limited negative interactions towards smaller carnivores, thus reducing the potential for spatiotemporal avoidance. Our study emphasises that avoidance patterns leading to substantial spatiotemporal partitioning are not ubiquitous in carnivore guilds.

Same place, different time, head up: Multiple antipredator responses to a recolonizing apex predator.

Prey adjust their antipredator behavioral tactics to minimize the risk of an encounter with predators. Spatiotemporal responses of prey to predators have been reported, but the nature of antipredator response is not ubiquitous and it is the object of increasing interest, especially considering the recent recovery of large carnivores in Europe, and the potential for behavioral antipredator responses to elicit consequences at the ecosystem level. We have tested multiple antipredator responses by fallow deer Dama dama to wolf Canis lupus in a Mediterranean protected area recently recolonized by this apex predator. Through intensive camera trapping, we tested for temporal and spatial association between predator and prey, and we have also studied deer vigilance in forest habitats where focal observations are usually impossible. Wolf detection rates were spatially associated with those of fallow deer. Accordingly, no evidence was found for fallow deer avoiding sites with higher predator detection rates. Temporal activity patterns were significantly different between the 2 species, with the wolf being mainly nocturnal whereas fallow deer was active especially during daylight. A comparison with a preliminary study strongly suggests an increase in the diurnal activity of fallow deer along with the stabilization of wolf presence in the area. Both the rate and the duration of vigilance of female fallow deer increased with the local frequency of wolf activity. We suggest an antipredator response based on temporal-rather than spatial-avoidance, as well as increased vigilance.

Seasonal dynamics of competition between honey bees and wild bees in a protected Mediterranean scrubland

Due to the widespread use of pesticides and the lack of floral resources in many agricultural landscapes, beekeepers have moved numerous honey bee colonies in protected areas which could shelter an important diversity of wild bees. Here, we investigated the seasonal dynamics of the competition between honey bees and wild bees through a two‐year study of plant–bee networks in a Mediterranean protected area. We recorded the visitation rates of four bee groups: honey bees, small wild bees, large wild bees and bumblebees. Our study reveals that the competition for floral resources induced by honey bees is especially strong during the early spring and then decreases along the season for all groups of wild bees. We observed a competitive exclusion of all groups of wild bees illustrated by an avoidance of well‐flowered plant species in presence of honey bees. As a consequence, we detected a rewiring of large and small bee floral preferences linked to the presence of honey bees. In presence of honey bees, Rosmarinus officinalis and Cistus albidus were significantly less visited by large bees. This study underlines the need to mitigate the establishment of numerous honey bee colonies in protected areas as honey bees could strongly affect the foraging activity of wild bees.

Forest accessibility, Madonie mountains (northern Sicily, Italy): implementing a GIS decision support system

ABSTRACT Valorisation and sustainable exploitation of woody biomass from cultivation interventions might be an important opportunity to track alternative development trails for rural communities in natural protected areas. The governance of Mediterranean protected areas is characterized by overlapping, sometimes conflicting institutions, stakeholders and regulations, causing negative impacts on decision-making processes. We present an open source GIS-based decision support system tool for mapping forest accessibility and optimizing woody biomass extraction. Two models were implemented to support forest managers during the decision-making process in designing and managing wood-energy supply chains. The optimal grid resolution to run the models was determined via a Least Cost Path analysis. The models were executed at different scales, performing satisfactorily when distances between recorded and modelled paths were lower than the grid unit. The higher the scale, the more the percentile of distances lower than the grid unit. The models were validated in Madonie mountains, Sicily, Italy.

Social actors\u2019 perceptions of wildlife: Insights for the conservation of species in Mediterranean protected areas

In the current Anthropocene Era, with numerous escalating challenges for biodiversity conservation, the inclusion of the social dimension into management decisions regarding wildlife and protected areas is critical to their success. By conducting 354 questionnaires in a Mediterranean protected area (the Biosphere Reserve of Bardenas Reales, Northern Spain), we aim to determine sociodemographic factors influencing knowledge levels and perceptions of species and functional groups as, emblematic and threatened. We found that hunters and animal husbandry workers knew more species than other social actors. Additionally, the perception of functional groups as threatened or emblematic differed between social actor groups, with statistically significant associations between perceptions and the characteristics of respondents. Interestingly, we found that although elusive steppe species are globally considered as endangered, these species were the least known by all social actor groups and rarely perceived as emblematic. This research is a novel approach and provides a better understanding of how perceptions can facilitate conservation decisions, particularly regarding endangered speciesGraphic abstract

Morphometric identification of honey bee subspecies reveals a high proportion of hybrids within a Mediterranean protected area

The importance of natural protected areas for the preservation of locally adapted subspecies (or local genotype) of honey bees has been recently emphasized in the literature. In western Europe, initiatives have emerged to protect the native subspecies i.e., the Western European dark bee, Apis mellifera mellifera (Hymenoptera: Apidae). Here, we investigated the honey bee subspecies diversity in a Mediterranean protected area, Calanques National Park, near Marseille, France. We found that the population of honey bees is mainly composed of hybrids between Apis mellifera mellifera and Apis mellifera intermissa. These hybrids might have a better resistance to the Varroa mite and a better adaptation to arid Mediterranean climate. Before promoting the native honey bee subspecies, Apis mellifera mellifera, it appears essential to identify honey bee subspecies used by beekeepers in protected areas.

Effects of buildings on plant composition and diversity in a Mediterranean protected area

In natural protected areas, buildings such as small villages, farms, shepherd's huts, camps, small hotels or visitor centres are common, usually at very low densities. Although buildings could play a role in modifying the biodiversity of natural protected areas, there has hardly been any attempt to describe the composition and characteristics of the vegetation associated with these buildings. Here, we analysed if there is specific vegetation associated with buildings in a set of six buildings within the Doñana National Park (SW Spain). We used Detrended Correspondence Analysis to identify trends of variation associated with buildings, and G-tests to examine if the species associated with buildings differed significantly in geographical distribution and functional characteristics from the species of the natural area. To compare species richness between the plots associated with the buildings and those associated with the natural area, sample-based rarefaction curves were created using incidence data. We found that buildings increased the richness of plant communities, mainly of species with a wide geographical distribution or which are adapted to heavy disturbance. This effect remained even 40 years after abandonment, which means that buildings act as a long-lasting refuge for ruderal and invasive plant species that remain around them, but not invading the surroundings unless there are disturbances. We conclude that the perturbation caused by isolated buildings seem to create localized plant diversity hotspots in the sands of the Doñana ecosystems that remain distinct from the surrounding natural area for decades.

Competitor densities, habitat, and weather: effects on interspecific interactions between wild deer species.

There is a growing interest on the potential interplay between weather, habitat, and interspecific competition on population dynamics of wild herbivores. Favorable environmental conditions may buffer the negative effects of competition; conversely, competition may be expected to be stronger under harsh environmental conditions. We investigated relationships between competitor abundance, weather, and habitat cover on density and local distribution of a medium‐sized herbivore, the roe deer Capreolus capreolus, as well as its spatial overlap with fallow deer Dama dama in a Mediterranean protected area. Over 11 years (2007–2017), roe deer density was not affected by spring–summer rainfall in the previous year and decreased with increasing density of fallow deer in the previous year. Hence, over the considered temporal scale, results supported a major role of competition over weather in influencing population trends of roe deer. At a finer spatial scale, roe deer occupancy was negatively affected by local abundance of fallow deer, especially in “poorer” habitats. We found a slight support for a positive effect of fallow deer density on interspecific spatial overlap. Moreover, fine‐scale spatial overlap between deer species increased with decreasing rainfall in spring–summer. Fallow deer were introduced to our study area in historical times and their role as superior competitors over roe deer has been found also in other study areas. We suggest a potential role of harsh weather conditions during the growing season of vegetation (i.e. scarce rainfall) in triggering the potential for ecological overlap, emphasizing the negative effects of interspecific competition.

To what extent is integration pursued in compulsory planning tools concerning coastal and marine areas? Evidences from two Mediterranean protected areas

Coastal areas are worldwide characterized by multiple pressures generated by high levels of urbanization and by conflictual and inappropriate uses. The establishment of protected areas represents a tool to contrast such pressures. The integration between planning tools represents a key issue, in particular in the Mediterranean area; hence, it has been addressed by both legally binding acts and voluntary agreements and charters concerning coastal zone management as well as marine spatial planning. By looking at two Italian case studies and analyzing their planning documents currently in force, our study aims at assessing the level of integration in relation to planning and management of areas characterized by the coexistence of various nature protection regimes. Our analysis shows that, although integration seems to be a key point in the planning agenda and in spite of some improvements, an integrated management approach in Mediterranean coastal and marine areas is still in its infancy. The results of the analysis show that, rather than contributing to building an integrated approach to marine and coastal zone management, each planning tool focuses on complying with its sectoral, normative framework. This situation can partly be attributed to the multilayered, and complex, Italian framework, characterized by several categories of protected areas with their own legal act and objectives.

Pollinator Specific Richness and Their Interactions With Local Plant Species: 10 Years of Sampling in Mediterranean Habitats.

In the context of global pollinator decline, little is known about the protection status and ecology of many species. This lack of knowledge is particularly important for Mediterranean protected areas that harbor diverse pollinator communities and are subject to considerable anthropogenic pressures. Calanques National Park (85 km2), which is located near Marseille (France), is dominated by Mediterranean low-vegetation habitats, such as phrygana and scrublands. These habitats offer favorable conditions for pollinator species due to the important amount of floral resources. Within a 10-yr period, we recorded bee (Hymenoptera: Apoidea: Anthophila), hover fly (Diptera: Syrphidae), and bee fly (Diptera: Bombyliidae) species and their interactions with the local flora through 10 field campaigns. We caught 250 pollinator species, including 192 bees, 38 hover flies, and 20 bee flies, for a total of 2,770 specimens. We recorded seven threatened bees (six near threatened and one endangered). Among the bee species, 47.9% were below-ground nesting species, and 54.7% were generalist species. Analysis of the pollination network showed that generalist and specialist pollinators do not share the same floral resources. The Cistaceae plant family (Malvales: Cistaceae) acted as a central node in the plant-pollinator network, interacting with 52 different pollinator species, which shows the importance of large open flowers that could be easily visited by both short and long-tongued pollinators in Mediterranean habitats. The occurrence of pollinator species and their ecological traits should strongly contribute to reinforcing the available information to provide or ameliorate the conservation statuses determined by IUCN Red List.

The policyscape of agroforestry within Mediterranean protected landscapes in France

Agroforestry systems (AFS) are presented as systems likely to meet a variety of interests from diverse stakeholders embodied in sectoral policies such as forestry or environment policies. However, they are in a process of being institutionalized in Europe through specific policy instruments mostly within agricultural policies. In this context, we investigated the agroforestry policyscape, meaning the social and spatial articulation between multiple policies impacting agroforestry along a Mediterranean landscape gradient from agricultural intensification to land abandonment. We focused on the necessary conditions to promote socio-political synergies between practices, actors and instruments to tackle agroforestry, from preexisting to emerging systems and issues in these landscapes. We worked in two Mediterranean protected areas, the Ventoux Biosphere Reserve and the Verdon Regional Nature Park, and conducted in-depth interviews with 50 practitioners and sectoral representatives from diverse policies directly affecting AFS. We identified five categories of AFS, some of them being traditional declining practices while other ‘modern’ forms are currently emerging with the ongoing agro-ecological transition. We highlighted that while stakeholders and policies from multiple social groups are interested in some AFS such as silvopastures, others AFS such as silvoarable systems are confined to a single social and political field, the agricultural one, or even ignored by policies such as grazed orchards. Regarding this agroforestry policyscape, we discuss opportunities for agroforestry development with issues of policies coordination, lack of instruments, and need for synergies with environmental or land-use planning policies.

Estimating wild boar density and rooting activity in a Mediterranean protected area

The mitigation of ecological/economic impacts of wild boar Sus scrofa is one of the most challenging issues in wildlife management worldwide. Monitoring population density and impact of wild boar is crucial to plan appropriate management actions to reduce its density, environmental impact and epidemiological risk, as well as to evaluate control effectiveness. In 2018–2019, we used plot-based faeces counts, coupled with specific estimates of daily defecation rates, to estimate wild boar density and rooting activity in natural/semi-natural habitats, in a Mediterranean protected area. Daily defecation rate was 6.7 faeces/individual, much lower than that of ruminants. We obtained estimates of 70.0–70.5 faeces/km2, corresponding to wild boar densities of c. 10.5 individuals/km2 (relative standard error: 18%) in both years. Low daily defecation rates and skewed distribution frequencies of wild boar faeces should be considered to plan surveys with an adequate sampling design and intensity. Faeces abundance and rooting activity peaked in ecotones, i.e. open areas at the interface of wood patches, whereas they did not differ between other habitat types, suggesting a fine-scale concordance between the two indicators. Long-term monitoring is needed to assess relationships between indicators of impact and abundance at a broad scale. Our work shows how to undertake simultaneously wild boar density estimates and impact assessment in natural environments, which is particularly important for protected areas and/or habitats of conservation concern across the globally distributed Mediterranean biome.

Characterization and challenges of livestock farming in Mediterranean protected mountain areas (Sierra Nevada, Spain)

Aim of study: To characterize and analyse the extensive livestock farming systems in environmental protected area and propose strategies for their sustainable improvement.Area of study: Sierra Nevada Protected Area (Spain)Material and methods: Data were collected from a sample of 85 farmers and 48 experts. The information from farmers was expressed in 35 variables, 23 of which were qualitative and 12 quantitative. A multivariate analysis was conducted.Main results: The principal components explained 71.2% of the total variance and the k-means cluster analysis identified three groups: C1 (38 farms), medium-size farms with a predominance of goats and relative dairy specialization; C2 (12 farms), large-size farms with extensive grazing lands, a high proportion of meat purpose animals and managed by young and dynamic farmers and C3 (35 farms), medium-size farms with a high proportion of meat purpose animals and undeveloped business management. The main problems reported were: insufficient pastures for livestock, stagnation of product prices, lack of generational renewal and need for social recognition of livestock farming. These obstacles could be overcome by implementing measures aimed at improving feed self-sufficiency -and thus reduce production costs- increasing income through social recognition of farming, achieving product differentiation, and strengthening short marketing channels. This would be favoured by an increase in associationism and specialized training.Research highlights: Farm management and marketing are important for improve these farming systems. The extensive livestock farming continues to be an important activity in European protected mountain areas.

Food habits of wolves and selection of wild ungulates in a prey-rich Mediterranean coastal area

Large carnivores are increasing throughout the western Holarctic, re-colonising large parts of their former ranges. Ecological (e.g., predator-prey relationships) and socio-economic (e.g., livestock depredation) consequences of this process need to be monitored to identify suitable management/conservation actions. We studied food habits and selection of main prey by wolves in a Mediterranean protected coastal area (Uccellina Hills in the Maremma Regional Park, c. 70 km2, central Italy, May 2016- April 2018), including sclerophyllic scrubwood, pinewood, wetlands and mixed rural-wood habitats. Potential prey include wild boar, fallow deer and roe deer (c. 25–30 individuals/100 ha, in summer, all species together), livestock (mainly cattle and sheep, c. 20 heads/100 ha, overall) and several species of meso-mammals. Overall, wild ungulates dominated the diet (c. 90% of absolute occurrence, relative occurrence or volume), with the fallow deer being the main prey (absolute occurrence, AO: 55%; relative occurrence, RO: 42%; estimated volume, V: 44%) followed by the wild boar (AO: 48%; RO: 36% V: 33%). Livestock was rarely used (2%, both AO and V); the coypu (AO: 8%; RO: 6%; V: 6%) was another important food item. Fallow deer and wild boar dominated summer diet, whereas the use of alternative prey increased in winter. Fallow deer were selected, wild boar were used according to their availability, whereas roe deer were used less than availability. Prey selection was probably driven by the greater accessibility and detectability of fallow deer, which are gregarious and attended mainly open habitats on lower ground, in respect to wild boar/roe deer. Most likely, availability of a diverse spectrum of meso-large prey and a comparatively lower accessibility of livestock were key-factors to limit livestock consumption.

Patterns of predation on native and invasive alien fish in Mediterranean protected and unprotected areas

Worldwide, the loss of predatory fish due to overexploitation has altered the structure of native communities and caused ecosystem shifts. Ecosystems deprived of high-level predators may be more vulnerable to invasive alien species as the latter are subject to reduced predation control. Marine protected areas (MPAs), and particularly no-take reserves where fishing is banned, can be effective tools for the restoration of predatory relationships within their boundaries. We explored whether the restoration of high-level predatory fish populations within Mediterranean MPAs can exert top-down control on alien fish. Fish tethering experiments, including native (Sardina pilchardus, Boops boops) and alien (Siganus rivulatus) dead specimens, were conducted to quantify predation within the no-take zones of three MPAs and in unprotected areas, and to assess potential differences in predation rates and prey type preferences. A subsample of experimental units was filmed to document predation events and related fish behaviour. More high-level predators interacted with the tethered fish inside the MPAs than in unprotected areas. Yet we did not find significant differences in the consumption of alien or native fishes between MPAs and unprotected areas. The native S. pilchardus was consumed more in comparison to the other tethered fishes, regardless of protection status and location. Interestingly, the alien S. rivulatus was consumed by native predators in the western Mediterranean locations where this alien fish is not established. Despite its limitations, our study provides evidence on the ability of some native predators to feed on and potentially control certain alien species without requiring ‘adaptive’ time-lag periods.

Wildfires impact on the economic susceptibility of recreation activities: Application in a Mediterranean protected area.

Development of many rural forestry areas depends strongly on tourism activities; therefore, it is critical to incorporate these activities in the decision-making process for the management and conservation efforts. Different from other market resources provided by forests, recreation activities provide benefits not only to forest owners but to all surrounding communities. Economic valuation of recreation activities requires using indirect valuation approaches like the travel cost method. Annual welfare estimates for the "Aracena y Picos de Aroche Natural Park" in southern Spain ranged from 25.30 € per recreationist for driving and travel time costs to 72.69 € per recreationist for these former costs plus associated incidental (food, lodging, etc.) costs. The annual value of this natural protected area was estimated at 3,656,609 € for the driving and travel time costs approach; and it was increased to 10,505,885.7 € for the total costs approach. Distributing the recreation welfare estimate proportionally is not reasonable as the visitation rate to different areas is different. Therefore, we use the individual recreational activities demand to distribute the estimated recreation value. Finally, we integrate the consumer surplus, the vegetation resilience and the potential fire behavior to estimate the fire recreation susceptibility. The fire susceptibility was increased by 58.25 million € from driving and travel time costs to total costs including incidental costs. Development of a socio-economic susceptibility framework using Geographic Information Systems provides an objective tool for budget allocation and prioritization of prevention activities and suppression actions during wildfires.
