“…This indicates a contrasting socioeconomic context in Turkey. However, the primacy of income potential was also a major factor in a similar study in Catalonia [12]. Our research has arrived at a similar result.…”

“…What can be implemented by smallholders and forest officers are simple sanitation measures such as limb removal and destruction, and elimination of dead and dying vegetative material [10]. Though some studies in the European context have looked at dynamics of land-owner interest in biological control measures [11,12], very few studies have investigated the effects of small-scale household blight mitigation efforts [13].…”

Socioeconomic Perspectives on Household Chestnut Fruit Utilization and Chestnut Blight Prevention Efforts in Turkey

Exotic pathogens, within the center of genetic diversity for the species, compromise European chestnut populations in Turkey. In Turkey today, the species is of tremendous economic, ecological and cultural importance. At this time of severe exotic pathogenic pressure on a highly-valued forest species, we ask, how does awareness of diseases and treatments as well as value for chestnut trees affect the efforts of households to manage pests and diseases of chestnut trees in Turkey? We conducted 96 surveys in 34 villages in 10 provinces across Turkey to investigate awareness of diseases and other challenges to the chestnut population, chestnut harvesting habits, family value for chestnuts and efforts to mitigate pest and disease pressure. We analyze our results using cluster and regression analysis. Our results show that based on analysis of all observed characteristics, our research sites in Turkey break cleanly into groups based on production level. Further, results demonstrate significant correlation between amount of chestnut-derived income and awareness of pests and diseases as well as the likelihood of households enacting disease mitigation measures. These results also demonstrate correlation between observed awareness of diseases and pests and the likelihood of households enacting disease mitigation measures.

“…Mismatches between observations in diseased areas and NFI data have been reported also previously. For instance, work on Cryphonectria parasitica and sweet chestnut in Spain showed contrasting results when comparing high incidence in managed stands with NFI data; the results indicated that instead of declining, chestnut population was increasing in volume, likely due to management abandonment of coppice stands 33 . www.nature.com/scientificreports www.nature.com/scientificreports/ Additionally, the records showed that some ash trees had been removed from the stands, although there was no information concerning the purpose of the removals and whether they were part of a management plan.…”

Determining the impacts of invasive pathogens on tree mortality and growth is a difficult task, in particular in the case of species occurring naturally at low frequencies in mixed stands. in this study, we quantify such effects by comparing national forest inventory data collected before and after pathogen invasion. in norway, Fraxinus excelsior is a minor species representing less than 1% of the trees in the forests and being attacked by the invasive pathogen Hymenoscyphus fraxineus since 2006. By studying deviations between inventories, we estimated a 74% higher-than-expected average ash mortality and a 13% slower-than-expected growth of the surviving ash trees, indicating a lack of compensation by the remaining ash. We could confidently assign mortality and growth losses to ash dieback as no mortality or growth shifts were observed for co-occurring tree species in the same plots. the mortality comparisons also show regional patterns with higher mortality in areas with the longest disease history in norway. considering that ash is currently mostly growing in mixed forests and that no signs of compensation were observed by the surviving ash trees, a significant habitat loss and niche replacement could be anticipated in the mid-term.www.nature.com/scientificreports www.nature.com/scientificreports/ forest have co-evolved with native pathogens, which target individuals weakened by inter-and intra-specific competition for resources. Changes in the population of the host would occur if the new pathogen caused a higher mortality than that occurring under natural conditions in the forest. Manion and Griffin 14 obtained the baseline mortality from a Liocourt curve calculated from tree inventories carried out over large areas. This model shows how the density of trees decreases as they increase in diameter. The underlying process behind this curve is that weaker trees eventually die, and the surviving trees increase their size as they occupy the newly freed space. The model is adjusted so that the same decay or mortality operates regardless of tree size, and thus can be used as a 'baseline mortality' value to be compared with when analysing areas affected by a new pathogen. Manion and Griffin 14 applied this approach to widespread tree species in eastern US; however, this model can be difficult to apply in the case of minor species, such as Alnus glutinosa, Fraxinus excelsior or Ulmus minor, affected by exotic pathogens in Europe. These species are poorly represented in national forest inventories (NFIs), and often appear in mixed natural stands where baseline mortality may be difficult to estimate.In this study, we focus on European ash (Fraxinus excelsior) in Norway. Ash, a keystone species with wide distribution and habitat range in Europe, is being affected by the non-native fungus Hymenoscyphus fraxineus (T. Kowalski) Baral, Queloz & Hosoya. European ash grows over a wide range of altitudes and soil moisture contents, depending on climatic and site conditions. It is frequently mixed with other broadleaved trees fr...

“…Agent sub-model: landowner behavior Forest owners are identified as primary agents of forest ecosystem services provision (Sotirov et al 2019). The literature on private forest owners shows that their decision-making process with regard to the management of their forests is not only based on economic factors, but also includes feelings of moral responsibility and pride (Oliva et al 2016). Moreover, others have argued that the intention of forest owners is to do "good" in their forests (Domínguez and Shannon 2011).…”

A key factor in the resilience of water and forest ecosystems in the face of climate variability is the management decisions taken by the individuals responsible for them, from public officials to private owners. The presence of economic and other non-material incentives can modify the decision-making processes of these individuals and thereby avoid current socioeconomic trends in Mediterranean forested areas such as land abandonment and its detrimental consequences for both social and ecological systems. In this article, we created a spatially explicit agent-based model to observe the effects of the implementation of a woodland-for-water payment for ecosystem services scheme in a local area in Catalonia (NE Spain). The results of the model show that the policy design that supports recurrent management practices obtains the same results at the 25-year mark that other policy designs at the end of the modeled period in number of managed hectares. This design entails the presence of a local intermediary, financial coverage of the management changes to improve water conditions, and the targeting of only one environmental goal, thereby avoiding the ecosystem trade-offs that can arise when two or more goals are targeted. In this design, the first generation of forest owners engaging in behavior change would benefit from their actions, which is also key for maintaining their engagement with the payments for ecosystem services scheme.
