“…For national and regional level inferences, more details are typically needed. For instance, in Italy, a forest type map with 14 classes based on the dominant species are used instead of the classes of the CORINE product [79]. However, at the local level, a classification system of higher levels in detail still might be needed.…”

“…If the bridging can be carried out by combining the more detailed classes to new ones, harmonized estimates can be obtained with a little work, as in reductive bridging. However, if the local classes have been developed for another purpose, and the new classes cannot be obtained by just combining the old classes, problems can arise [79]. For instance, the number of classes locally used may be different.…”

Forest information is needed at global, national and local scales. This review aimed at providing insights of potential of national forest inventories (NFIs) as well as challenges they have to cater to those needs. Within NFIs, the authors address the methodological challenges introduced by the multitude of scales the forest data are needed, and the challenges in acknowledging the errors due to the measurements and models in addition to sampling errors. Between NFIs, the challenges related to the different harmonization tasks were reviewed. While a design-based approach is often considered more attractive than a model-based approach as it is guaranteed to provide unbiased results, the model-based approach is needed for downscaling the information to smaller scales and acknowledging the measurement and model errors. However, while a model-based inference is possible in small areas, the unknown random effects introduce biased estimators. The NFIs need to cater for the national information requirements and maintain the existing time series, while at the same time providing comparable information across the countries. In upscaling the NFI information to continental and global information needs, representative samples across the area are of utmost importance. Without representative data, the model-based approaches enable provision of forest information with unknown and indeterminable biases. Both design-based and model-based approaches need to be applied to cater to all information needs. This must be accomplished in a comprehensive way In particular, a need to have standardized quality requirements has been identified, acknowledging the possibility for bias and its implications, for all data used in policy making.

“…Harmonization of nomenclature systems between the four regional data sets was available from Vizzarri et al (2015). The methodology used to harmonize the four different FT nomenclature systems available for the data sets followed a bottom-up approach, from local to European level, and from FTs to FCs.…”

To support sustainable forest management, planning policies and environmental actions, it is essential to have available common and standardized geospatial information on forest structure, composition and distribution. In this paper we present a harmonized forest categories (HFCs) map of four administrative Regions located in central Italy (i.e. Marche, Abruzzo, Lazio and Molise) at a scale of 1:400,000. The study area extends over 42,246 km 2 , 14,878 km 2 of which are covered by forests. Four regional forest maps were harmonized in order to produce common standardized information on composition, structure and the distribution of forests in central Italy. A forest category is a forest vegetation unit defined by the main tree species composition. In this study we adopted a nomenclature scheme composed of 16 forest and shrubland categories. This work represents the first HFCs map in Italy over a large area. The legend is also harmonized with the European Environment Agency forest types nomenclature. ARTICLE HISTORY

“…The altitude of the region ranges from sea level to 2050 m a.s.l., while annual precipitation amount ranges from 674 mm (Adriatic coast) to 1614 mm (Matese massif). The area is covered by more than 155,000 ha of Mediterranean and temperate forests (approximately 35% of the region extent), with a dominance of turkey oak (40%), downy oak (22%) and beech (10%) forests, and important relict areas for silver fir (Santopuoli et al, 2014;Vizzarri et al, 2014). Factors linked to natural disturbances, e.g.…”

Long-term effects of traditional and conservation-oriented forest management on the distribution of vertebrates in Mediterranean forests: a hierarchical hybrid modelling approach

et al. 2015

Aim Recently, increasing attention has been devoted to the development of sustainable forestry practices aimed at finding a balance between the maintenance and enhancement of different forest resources. However, the long‐term, large‐scale effects of conservation‐oriented forest management on vertebrates have been poorly studied. We tested the hypothesis that conservation‐oriented forest management, being conceived to mimic the dynamics of a natural forest succession more closely than does traditional forestry, causes a less severe long‐term impact on the distribution of forest vertebrates. Location Molise region, Central Italy. Methods We proposed a hybrid modelling framework based on the integration of a forest dynamic model (‘LANDIS‐II’) with species distribution models (SDMs). The framework was applied on four forest specialist vertebrates (tiny salamander, slow worm, Eurasian nuthatch and Leisler's bat) and included three components: forest dynamic model (FDM), SDMs and spatial pattern analysis (SPA). FDM was used to simulate spatially explicit patterns of forest succession for the current time and for 2050, imposing three alternative forestry scenarios. The simulated forest succession patterns were analysed through SPA to calculate spatialized landscape metrics that were adopted as environmental predictors for SDMs. Landscape trajectories were calculated on current and future species distributions predicted with SDMs to evaluate the effect of alternative forestry practices on their extent and fragmentation. Results Forest management mainly affected the spatial configuration rather than the extent of the species potential distributions. Conservation‐oriented forest management was more favourable than traditional forestry in increasing the extent and reducing the fragmentation of the studied species’ distributions. Main conclusions Conservation‐oriented forest management, by mimicking the dynamics of a natural forest succession more closely than did traditional practices, favoured elements, such as forest unevenness, species richness, aggregation of patches and variability in their distances, which emerged as fundamental characteristics for preserving the long‐term persistence of forest vertebrates.
