Selective and traditional forest management options for black pine forests in Central Italy: effects on ecosystem services

Abstract

Sustainable Forest Management (SFM) should be able to produce an optimal level of bundle of Ecosystem Services (ES), thus ensuring more resilient forest ecosystems also creating benefits for local population and human well-being. Yet, choosing between alternative forest management practices is not straightforward as it necessarily involves ES trade-offs. Forest management decisions have to reconcile the socio-economic and ecological contributions of forest ecosystems by fostering a synergistic relation between multiple ES while lowering ES trade-offs. The aim of the study is to analyze different forest management practices (selective and traditional thinning) in black pine peri-urban forest in Central Italy, by investigating their contribution in terms of provisioning (wood production), cultural (recreational benefits), regulating (climate change mitigation) ES. For each management option was performed: (1) the biophysical assessment of selected ES by using primary data and calculating indicators for wood production with special regard to biomass for energy use (living trees and deadwood volume harvested), recreational benefits (tourists’ preferences for each forest management practice), climate change mitigation (carbon sequestration in above-ground and below-ground biomass), and (2) the economic valuation of wood production, recreational benefits and climate change mitigation ES using direct and indirect methods (environmental evaluation techniques). The results show that the effects of the selective thinning on ES is higher that the effects of the traditional thinning. The economic value of the three ES provided by traditional and selective thinning are respectively: bioenergy production 154.2 € ha -1 yr -1 and 223.3 € ha -1 yr -1 ; recreational benefits 193.2 € ha -1 yr -1 and 231.9 € ha -1 yr -1 ; carbon sequestration 29.0 € ha -1 yr -1 and 36.2 € ha -1 yr -1 . The integrated (biophysical and economic) assessment of ES in addition to the trade-off analysis can provide multi-perspective insights for forest policy makers and can be included as a part of the local forest management plans.
