Abstract
- • There is a clear trade-off between the provisioning and other ecosystem services. • Shorter rotations provide better opportunities for timber, C and water production. • Longer rotations create better condition for cultural values, biodiversity and soil protection. • Short rotations lead to higher harvest rate and a more regulated forest structure. • Better combination of management interventions with a better suited tool is needed for an optimal rotation. Addressing the spatio-temporal dynamics of forest development under different management scenarios with varying rotation lengths is a challenge in forest management planning. This research aims to forecast forest development and assess the relative consequences of varying rotation lengths on several ecosystem services such as wood production, habitat for biodiversity, carbon sequestration, water provision, soil protection and cultural values. Forest development is simulated with the ETCAP model to examine the long-term effects of various rotation lengths with silvicultural prescriptions on the ecosystem services. Bürücek forest planning unit is used as a case study area with 10,711 ha forests in upper Mediterranean region of Turkey. Shorter rotation lengths are considered one of the main mitigation measures to climate changes in forestry; however, lead to the increased harvest level, net present value, ground water and soil loss, and reductions in the largest stand volume, understory, basal area, carbon storage and the cultural values with less regulated forest structure. The management scenarios with longer rotation lengths, however, have highlighted improvements in the carbon storage, larger standing volume, mean stand age, basal area and cultural values, and reductions in the mean harvest volume, net present value, ground water and soil loss due to larger-even distribution of tree sizes and stand development stages. An aspiration for a higher level of provisioning services for economic motivations may need to be discarded for the sake of enhancing the capacity of forest ecosystems to sequester more carbon and provide better habitat condition for biodiversity conservation with a careful design and selection of rotation lengths. Overall, the choice of optimal rotation length is highly dependent on a desired set of management objectives and target forest structure driven mostly by management interventions with the appropriate type and level of ecosystem services, provided that a thorough understanding of forest dynamics is achieved by considering both risks and uncertainties associated with natural disturbances and socio-economic conditions.
