Abstract
Aim Roads impact wildlife in different ways, among which road mortality has been the most studied. Budgets in conservation biology are usually small, and macroecological approaches have been employed in recent years as the first steps towards guiding management. Carnivores are particularly vulnerable to mortality on roads due to their elevated ecological needs (low population density, often low fecundity and relatively large home ranges). Our aim was to develop a ranking methodology to prioritize specific areas for road‐kill mitigation. Location Continental Italy. Methods We studied 271 occurrences of live polecats (Mustela putorius ) and 212 polecat road‐kill sites. We used the former to generate a species distribution model and the latter to identify the variables that determined the road‐kill risk. Habitat suitability was derived from a spatial distribution model that combined the polecat occurrence data with a set of environmental variables. Prey availability was derived from the combination of suitability maps of 26 prey species. We used generalized linear modelling to identify the set of variables that best explained the occurrence of road‐kills. The variables included in the best performing model were combined to produce the road risk map and to identify the areas with the highest densities of road sections with highest risk. Results Road‐kills were positively associated with the road sections with higher broad‐leaved forest coverage. The number of casualties was found to be higher than expected on the national and provincial roads and lower than expected on the local roads. Main conclusions This approach allowed us to identify the 10 × 10 km cells where mitigation actions to prevent road‐kills should be prioritized. As mitigation actions (wildlife passage construction, fencing) are expensive, measures should be prioritized on the specific high‐risk road sections inside these selected cells, avoiding generalized mitigation plans.

Where will it cross next? Optimal management of road collision risk for otters in Italy

Autori

Abstract
Collisions with vehicles represent the main conflict between infrastructures and wildlife, causing damages to both humans and animals. As to the latter, road mortality is a growing phenomenon and the largest single cause of death for many vertebrates. When focusing on endangered species, the Eurasian otter (Lutra lutra) is among the most vulnerable to road-kills, which represent the predominant cause of deaths recorded in Europe. We propose a large scale spatially-explicit assessment of road-kill risk for the Eurasian otter in Italy as a tool to identify road stretches at high collision risk, thus optimizing the location of mitigation measures. The modelling approach was produced for South Central Italy, hosting the only remnant viable population of otters in Italy. We used a maximum entropy approach including 56 road collision events recorded between 2004 and 2016 through a citizen science initiative, along with seven environmental predictors measured on 1 km grid cells. Four pre-dictors were selected to describe roads characteristics, i.e. density of highways, and of state, regional and local roads. The remaining three variables referred to the quality of otter habitat in the surrounding of the collision sites, i.e. elevation, density of freshwater bodies, and a measure of landscape heterogeneity calculated on land-cover categories. The model achieved a good predictive accuracy (AUC > 0.8; Boyce index > 0.8). The collision probability was mostly affected by elevation, density of state roads, and density of freshwater bodies. Specifically, collision risk was higher in areas at low elevation and medium density of state roads located near rivers and wetlands. In addition, model predictions evidenced that implementing mitigation measures along 10% of road network in the study area could have potentially hampered ca. 50% of otter casualties recorded during the study period.

Abstract
Collisions between wildlife and vehicles represent the main conflict between infrastructures and ecosystems. Road mortality is the largest single cause of death for many vertebrates, representing a growing phenomenon of remarkable dimension. Most studies in road ecology investigated spatial roadkill patterns, showing that roadkill probability is often higher near optimal habitat for a large amount of species. Landscape connectivity has been less often considered in roadkill research, and only few studies considered habitat suitability and landscape connectivity at the same time. The purpose of the present study was to evaluate the relative importance of habitat suitability and landscape connectivity in determining roadkill risk for a habitat-generalist carnivore, namely, the Eurasian badger in the Abruzzo region (Central Italy). We collected occurrence data of living individuals from camera trapping and roadkill data of through a Citizen Science initiative. We used the occurrence data to produce a habitat suitability model (HSM) and a landscape connectivity model (LCM). Both HSM and LCM were then used as predictors in combination with road characteristics to fit a roadkill risk model. We found that landscape connectivity was more important than habitat suitability in determining roadkill risk for the Eurasian badger. Overall, the density of regional roads was the most important variable. Our finding highlighted how important is to consider landscape connectivity in planning mitigation measures aimed to preserve habitat-generalist species.

Abstract
In the last decades, wildfires have considerably changed in their frequency, extension, intensity and this is mainly due to climate change and human activities. The year 2017 was particularly significant for the amount of hectares burned in Southern Europe and especially in Italy. Remote sensing has been used to map and monitor wildfires around the world. In the last years, the advent of monitoring programs such as Copernicus (handled by the European Commission in partnership with the European Space Agency) offers a unique opportunity to monitor several land features, including wildfires. The aim of this paper is to map the 2017 fire occurred on the Morrone Mountain, in the Majella National Park. We used pre and post Sentinel 2-A data to map burned areas and to define severity classes. We also quantified burned areas in terms of land cover categories and Natura 2000 habitat types. The analysis showed that the burned area is 2184 ha, of which 84% (1837 ha) is within the Majella National Park limits (4% of the entire Park area). Most of the burned area is occupied by shrubs and grasslands, most of which are Natura 2000 habitats. Other burned areas are coniferous plantations and beech forests. The Sentinel 2-A imagery offers consistent, reproducible and unbiased recordings of fire features, an useful tool in remote and mountainous areas such as the Majella National Park.

Abstract
Scarce information is available on the current status of Apennine populations of Alectoris graeca. In this paper, data on recent distribution of the species in each Apennine region and data on census in several Apennine areas are reported. In Marche region, the size of population was estimated in 110-137 pairs and maximum density (1.25 pairs/ km2 ) was observed in M. Sibillini National Park. In Umbria region, the size of population was estimated in 9-23 pairs. In Lazio region, the size of population was estimated in 171-342. pairs and the highest densities were recorded in the Reatini Mountains (2.02 pairs/ km2 ) and in ‘Montagne della Duchessa’ natural Reserve (1.90 pairs/ km2 ). In Abruzzo-Molise regions, the size of population was estimated in 1500-1700 pairs and highest regional densities were recorded in the Maiella National Park (4.2 pairs/ km2 ) and Velino Sirente Regional Park (2.10 pairs/ km2). In Campania region, the specie was present only in Cilento e Vallo di Diano National Park, where the size of regional population was estimated in 84 pairs. In Basilicata-Calabria regions, population was estimated in 55-120 pairs. The Apennine population of rock partridge was evaluated in 1939-2436 pairs. The distribution of rock partridge showed that many Apennine, pre-Apennine and anti-Apennine areas, apparently suitable for the species, were not occupied. Factors limiting the expansion and the growth of populations of rock partridge in Apennine areas are highlighted. A correct management of populations of Abruzzo region, in particular of local hunting pressure, plays a pivotal role for the conservation of Apennine rock partridge.
