Titre : Towards an indicator system to assess equitable management in protected areas Type de document : texte imprimé Auteurs : N. Zafra-Calvo, Auteur ; U. Pascual, Auteur ; D. Brockington, Auteur ; B. Coolsaet, Auteur ; J.A. Cortes-Vazquez, Auteur ; N. Gross-Campf, Auteur ; I. Palomo, Auteur ; N.D. Burges, Auteur Année de publication : 2017 Article en page(s) : pp. 134-141 Langues : Anglais (eng) Catégories : [Thèmes] Aire protégée Mots-clés : indicateur gestion équitable Résumé : "Aichi Target 11 (AT11), adopted by 193 Parties to the Convention on Biological Diversity (CBD) in 2010, states that protected areas (PAs) must be equitably managed by 2020. However, significant challenges remain in terms of actual implementation of equitable management in PAs. These challenges include, among others, the lack of a standardized approach to assess and monitor social equity and the difficulty of reducing social equity to a series of metrics. This perspective addresses these challenges and it proposes a minimum set of ten indicators for assessing and monitoring the three dimensions of social equity in protected areas: recognition, procedure and distribution. The indicators target information on social equity regarding cultural identity, statutory and customary rights, knowledge diversity; free, prior and informed consent mechanisms, full participation and transparency in decision-making, access to justice, accountability over decisions, distribution of conservation burdens, and sharing of conservation benefits. The proposed indicator system is a first step in advancing an approach to facilitate our understanding of how the different dimensions of social equity are denied or recognized in PAs globally. The proposed system would be used by practitioners to mainstream social equity indicators in PAs assessments at the site level and to report to the CBD on the ‘equitably managed’ element of AT11."

[Thèmes] Relation plante - animalMots-clés : acidification facteur biotique eutrophisation perte d'habitat Résumé : "Monophagous butterflies often have smaller ranges than their host plants, which could relate to host plant abundance. Many specialist butterflies have already gone regionally extinct and studies of the role of host plant and habitat abundance at resolutions sufficiently detailed to cover host plant abundance are urgently needed for conservation management. Here, we investigate the link between a predominantly monophagous butterfly – the critically endangered Euphydryas aurinia and its host – Succissa pratensis in Denmark using high resolution (1 × 1 km) butterfly distribution data and an extensive national host plant frequency data set. More specifically, we assessed whether patterns in the present day distribution of S. pratensis and its habitat can explain the current distribution of E. aurinia and which ecological factors determine habitat suitability for S. pratensis. We used logistic regression to model the occurrence of E. aurinia as a function of habitat and host plant abundance as well as connectivity among habitats. We also modelled the occurrence of S. pratensis from habitat type, soil type, precipitation and indicators of soil moisture, nutrient level, and pH using generalized additive models. The remaining E. aurinia populations are confined to small regions in northern Jutland and this pattern was well predicted by our model. High modelled probabilities of E. aurinia coincided with habitat abundance exceeding 6–7% of land area and host plant frequency within habitat exceeding 40% at plot scale. Habitat connectivity was not included in the most parsimonious model. S. pratensis occurrence probability increased with pH, decreased with nutrient status and showed a unimodal response to soil moisture. The geographic partitioning of pH and nutrient effects indicated host plant scarcity due to eutrophication in Eastern Denmark and acidification in Western Denmark. Our findings highlight the importance of identifying empirical thresholds for habitat and host plant abundance in future conservation of herbivorous insects while also taking host plant habitat requirements into account."

[Espèces (in biblio)] Calluna vulgaris
[Thèmes] PâturageMots-clés : Panicum acuminatum fauchage diversité végétale brûlage conservation gestion Résumé : "Throughout the last decades, Calluna vulgaris (L.) Hull heathlands have declined across Europe and nowadays their conservation is particularly challenging at the southern edge of their distribution. In the Nature Reserve of Vauda (north-western Italy), six restoration treatments were applied (extensive annual goat browsing, one-off mowing, annual mowing, one-off fire without and with annual browsing, and annual fire) and their effects on plant diversity and the cover of C. vulgaris, its competitor grass Molinia arundinacea Schrank, woody, and alien species were monitored between 2005 and 2011. In the short-term, most of the treatments changed the vegetation community, reducing C. vulgaris cover according to a gradient of increasing biomass removal. In the mid-term, C. vulgaris, M. arundinacea, woody and alien species cover followed different trajectories according to the treatment and functional group. Annual fire shifted the vegetation towards a M. arundinacea-dominated community, while extensive annual browsing did not affect the heathland community and resulted in the lowest increase in M. arundinacea, which showed a remarkable fitness in these environments. Moreover, annual burning and mowing were effective in reducing woody species encroachment (p < 0.05), and fire treatments triggered a peak in alien species cover (mainly Panicum acuminatum Swartz) in the short-term. Six years after treatment, species richness and Shannon index did not differ between treated and control sites (p > 0.05). In conclusion, these results highlight the need and potential benefit of integrating multiple techniques to preserve C. vulgaris heathlands at their southern edge."
