“…Land use change and modifications of human practices are a major threat to rare species populations in the Mediterranean region (Amat, Vargas, & Gómez, 2013;Andrieu, Thompson, & Debussche, 2007;Domínguez Lozano, Moreno Saiz, & Sainz Ollero, 2003;Gauthier et al, 2017;Hardion et al, 2015;Minuto, Casazza, & Profumo, 2004;Pouget, Baumel, Diadema, & Médail, 2016;Salanon, Gandioli, Kulesza, & Pintaud, 1994). Initially, eight populations were "expected" to have some form of impact and indeed one population of each of S. capensis, O. mitissima and C. lineatus showed a significant decrease in both occupation and abundance, and the latter two populations disappeared before the end of the study.…”

“…In the face of these constraints, the use of frequency data based on presence / absence observations and/or classes of abundance for the yearly monitoring of plant populations provides an interesting alternative to obtain pertinent information to assess population trends (Berjano et al, 2013;Elzinga et al, 1998;Gauthier, Pons, Letourneau, Papuga, & Thompson, 2017;Joseph, Field, Wilcox, & Possingham, 2006). These authors illustrate how analyses of population transitions based on changes in frequency offer several advantages.…”

“…However, because many sites were visited on repeated occasions and often by different people (as revealed by the dates and observer identity in the database for each point), many of the points represent repeated observations within individual populations. In order to delimit populations, we considered that two points with a distance of at least 500 m (for annual species) or 1 km (for perennial species) between them are part of different populations if there are no other points between them (in a similar way as done by Gauthier et al, 2017). We thus aggregated points that occur at lower distances into populations.…”

“…It has thus become essential to quantify the direct impacts of human activities on natural populations and the ever-increasing threat to populations associated with urbanisation in the surrounding landscape. In a previous study of different populations of Allium chamaemoly in the Mediterranean region of the South of France, the combination of factors directly impacting population trends (meteorological events and direct human disturbance) with surrounding indirect threats due to fragmentation and human presence provides insights into the vulnerability and conservation status (Gauthier, Pons, Letourneau, Papuga, & Thompson, 2017).…”

In this paper, we propose a method to assess population numbers and quantify their vulnerability for listed plant species. For six study species, the spatial aggregation of point data allowed us to identify the numbers of populations for each species and thus how they differ in regional abundance. We assessed vulnerability by according a score to each population in relation to three criteria: (i) land-use (urbanisation, agriculture and natural areas), (ii) fragmentation of populations by infrastructures and (iii) protected status of populations. As a result of the combination and scoring of populations across the three criteria, only 9% have a low extinction risk and 73% are in one of the three classes of high vulnerability with 16% in the highest category. Finally, 29 of 32 populations monitored in a separate study are in one of the three highest categories of vulnerability. This study illustrates how information on population numbers of listed species at the regional scale brings to the fore their generalised vulnerability to threats in the Mediterranean landscape. This information is vital for conservation management staff to develop a strategy and appropriate actions for listed species' protection.

“…For example, Mikkonen and Moilanen [35] used the Zonation framework and software, which is a spatially explicit modeling tool, to identify areas of conservation priority within the Natura 2000 network. Other approaches have considered multiple criteria, used scoring methods, and applied specific decision rules to indicate conservation priorities and focused on habitat vulnerability [25,28,36]. These approaches focus on identifying the habitat types or species that are most in need of conservation; other approaches have focused on what conservation benefits could be most quickly achieved at the biogeographical level i.e., the "low-hanging fruit" approach [37].…”

Identifying Habitat Type Conservation Priorities under the Habitats Directive: Application to Two Italian Biogeographical Regions

The ongoing biodiversity crisis necessitates greater efforts to ensure the adequate conservation of critical habitat types. Even though the identification of protected areas is still required in Europe, conservation efforts are now focusing on management requirements for protected areas and habitat types. Establishing effective management approaches is important for the conservation of the natural and semi-natural habitat types that are identified under the Habitats Directive framework. In this study, we propose a methodology for determining priorities in the conservation management of habitat types based on readily available data. This method relies on four simple criteria to rank habitat types, which includes: conservation condition, biodiversity value, pressure factor, and the cover relevance of habitat types (indicating regional responsibility in terms of area covered). After ranking the habitat types based on the sum of the scores given to all of the criteria, the 25% top-ranking habitat types were prioritized. The pressure factors are analyzed using cluster analysis to better convey information regarding the management needs of groups of habitat types. This prioritization method was tested in habitat types occurring within the Italian Alpine and Continental biogeographical regions. From this analysis, forests, bogs and fens, and dry grasslands were identified as conservation priorities for the Alpine region; meanwhile, a wider variety of habitat types were identified for the Continental region. Important pressure factors were identified (e.g., roads and motorways) for these two biogeographical regions of Italy, which could be used to suggest specific conservation measures. The proposed approach represents a transparent and reliable method for outlining habitat-type priorities based on conservation, biodiversity, pressure, and cover factors, which can be applied to identifying conservation measures that can help achieve biodiversity targets.
