dc.description.abstractWe present a case study illustrating a multidisciplinary approach for characterizing, mapping and monitoring the bio-ecological properties of Mediterranean mountain grasslands in extensive grazing systems. The approach was developed to provide the basis for the management plan of a cluster of Natura 2000 special conservation areas in the Central Apennine mountains, Italy (with a total area of 79,500 ha, including 22,130 ha of grasslands). It includes a novel methodology for estimating sustainable stocking rates of different plant communities, at a detailed spatial scale over large areas, based on the integration of: (i) a classification of grassland types, based on physical habitat stratification and vegetation sampling; (ii) a forage-value assessment of each grassland type, obtained from field sampling of botanical composition and corrected with remote-sensing information on pasture microtopography; (iii) an estimate of primary productivity at a detailed spatial scale, obtained from the remote-sensed Normalized Difference Vegetation Index (NDVI) calibrated with biomass field data. Additionally, to obtain a bioclimatic characterization of the grasslands and to determine the optimal grazing season for each grassland type, intra-annual phenological signatures were obtained from the Enhanced Vegetation Index (EVI). Given the inherent limitations in the sustainable stocking rates concept, and the particular susceptibility of dry grasslands to changes in grazing regimes, we tested two biological indicators, the Auchenorrhyncha quality index (AQI) and the Arthropod-based biological soil quality index (QBS-ar). These indicators take into account above- and below-ground arthropod diversity, respectively, and are applied here for the first time to the specific purpose of monitoring grazing load effects on ecological quality and biodiversity of Natura 2000 dry grasslands. We conclude that: (i) it is possible to effectively integrate biomass estimates, obtained from publicly available satellite data, with a relatively simple field sampling of botanical composition, to achieve a detailed spatialization of sustainable stocking rates; (ii) within the same Natura 2000 habitat type there can be a large spatial heterogeneity in both sustainable stocking rates and optimal stocking season: thus, grazing should be kept under careful human control to maintain the habitats in the desired conservation status; (iii) while plant species richness was not correlated to grazing intensity, both AQI and QBS-ar had a significant negative correlation to grazing levels and can thus be useful for monitoring the actual “sustainability” of livestock loads on different aspects of grassland ecosystems.it
