“…This ecosystem change helped develop and retain human populations in these areas. The population decline associated with abandoned chestnut trees entails a decrease in specific ecosystem service and in species richness and biodiversity, which correlates closely to a steady increase in the leaf area index of the forest canopy (Gondard et al 2001). Regime shifts in social-ecological systems can cause rapid yet substantial changes in ecosystem services and human well-being.…”

ABSTRACT. Human practices have had an impact on Mediterranean ecosystems for millennia, particularly through agricultural and pastoral activities. Since the mid-19th century, land-use abandonment has led to the expansion of shrubland and forest, especially in the mountainous areas of the northern Mediterranean basin. Knowledge of these factors is vital to understanding present forest patterns and predicting future forest dynamics in the Mediterranean mountains. We aimed to analyze and understand how land-use abandonment affected spatial modifications of landscapes in two study areas, 44,000 ha and 60,000 ha, located on the island of Corsica, France, representing a typical Mediterranean environment with chestnut forests. Our approach used land-cover archive documents from 1774, 1913, 1975, and 2000, and human population history, 1770 to present day, to describe landscape patterns following land-use abandonment. This research showed that dramatic changes in landscape at the two study areas were caused by the suspension of human influence and the interruption of traditional farming practices. Over the study period, both study sites showed significant reforestation of shrubland and cultivated areas marked by the presence of Quercus ilex forests (+3. 40% yr-1 between 1975 and 2000) and by Pinus pinaster (+3.00% yr-1 between 1975 and 2000) at one study site that had experienced heavy rural exodus. At the same time, areas containing chestnut forests decreased by 50% between 1774 and 2000 (-0.09% yr-1 between 1774 and 1975 and -1.42% yr-1 between 1975 and 2000). Shrubland expansion remained limited at both study sites. Our study highlights the value of small-scale approaches for understanding the ecological consequences of land-use abandonment and present and future land-management decisions. Discussion concludes on the importance of working with long-term series for studies on resilience in social-ecological systems and on the consequences in terms of provision of ecosystem services.

“…On the one hand, the cessation of many forest practices is leading to the loss of cultural forest landscapes that were part of traditional agro-silviculture land-use systems (Mensing et al, 2018), with consequent loss of the associated biodiversity (Kraus and Krumm, 2013;Mölder, Streit, and Schmidt, 2014;Müllerová, Hédl, and Szabó, 2015). In our study area, this is the case with coppice stands (Müllerová, Hédl and Szabó, 2015), and chestnut grooves that were dominant landscape features as in other regions of the southern European mountains (Gondard et al, 2001;Pezzi, Maresi, Conedera, and Ferrari, 2011) 2. On the other hand, the rewilding process may overcome the challenges of sustainable development, contributing to the goals of protecting threatened species and habitats and of mitigating the impact of global warming (Kraus and Krumm, 2013;Sitzia et al, 2015;Chiarucci and Piovesan, 2019;Moomaw, Masino, and Faison, 2019) The Mediterranean area is one of the hot-spot of the global climatic crisis with several environmental problems (Cramer et al, 2018) and the rewilding landscape may be an effective strategy for carbon mitigation and biodiversity conservation (Sabatini et al, 2018b), with also an important buffering role toward the negative effect of climatic change (Filibeck et al, 2015;Betts et al, 2018).…”

Aim: In the last decades most European mountain forests have been abandoned after centuries of human management, paving the way for a landscape planning oriented to the conservation and rewilding of forest ecosystems. By resurveying historical vegetation plots in a mountain area of the Italian Apennines (southern Europe), we focused on yet overlooked processes in this area, to allow for a more comprehensive picture of the ongoing dynamics at a broad forest landscape scale. Location: Mountain forests in the northern Apennines, Italy. Methods: We resampled 22 historical forest vegetation plots recorded between 1934 and 1961. In each original quasi-permanent plot, three plots were sampled to improve the reliability of the comparison. We analyzed changes in forest cover, structure, alpha, beta, and gamma diversity, and ecological groups focusing on the understorey species community. Results: Forests are getting poorer in species in the understorey, with a higher tree layer and denser canopy cover. Alpha and gamma diversity significantly decreased from the original to the resurveyed plots. Several species of open habitats were associated with the original plots, while in the resurveyed plots several shade-adapted species were detected. Forest cover in the surroundings of the sites remained stable for the higher sites along the Apennines mountain ridge, while major changes in the surroundings and in species composition were detected for the plots located at lower elevations and marginal sites. Conclusions: Our main findings are in line with the majority of resurvey studies performed in European forests, with a general mesification of local communities after management cessation. Despite the limited number of available historical plots, their location along a wide gradient of elevation and naturalness allowed considering also the importance of site location, forest continuity and marginality as drivers of changes that need to be taken into account when planning conservation actions for restoration of mature forests.

Il castagno (Castanea sativa Mill.) è una delle specie forestali più importanti per il territorio europeo, tanto che Giacomini & Fenaroli (1958) l'hanno considerata un simbolo della vegetazione dell'Europa meridionale e da tempi remoti ha avuto una ampia diffusione al di fuori dell'area di indigenato. In Italia, secondo l'Inventario Nazionale delle Foreste e dei Serbatoi Forestali di Carbonio (INFC 2005) copre una superficie di circa 790 mila ettari e fino alla metà del secolo scorso ha rivestito un ruolo prioritario nell'economia delle aree rurali per la grande varietà di prodotti che da esso si potevano ottenere (Manetti et al. 2006 Abstract: Growth and yield models, assortment type and analysis of deadwood in chestnut coppice . Chestnut (Castanea sativa Mill.) is one of the most important forest tree species in Europe, and it is considered a symbol of the natural vegetation in southern Europe. In Calabria (southern Italy) chestnut forest covers an area of approximately 87000 hectares, most of which (about 80%) managed as coppice. In this study a growth and yield table has been elaborated. Thurthermore, assortment type and quantity of deadwood have been evaluated according to age of coppice and forest fire prevention, respectively. The study site is located in the "Presila of Catanzaro" and the research was carried out in 15 plots; the age of the examined stands ranged from 2 to 50 years old. More than 30000 shoots per hectare were recorded in the first two years after coppicing. As opposed, about 2300 and 1000 shoots per hectare were observed 15 and 50 years after coppicing, respectively. The culmination of the mean annual increment of the forest standing volume (16 m ) was observed at 15 years. Fifteen years after coppicing, most of the wood production was constituted by small dimension assortments. Twenty five years after coppicing small and large poles were the prevailing assortments while telegraph poles and timber beams increased after 50 years. The amount of deadwood in forest ranged between 11.9 and 68.7 m 3 ha -1 . The largest component was represented by standing dead shoots. The results show that coppice management can be adopted even if the main purpose of the chestnut stand is the production of large size assortments. In chestnut coppice, highly vulnerable to fire, the reduction of stand density with silvicultural practices (thinning and displacement) is the main way to promote the efficiency of forest and a higher strength and resiliency against forest fire.
