The assessment of forest vulnerability and resilience in the sight of global ecological, social and economic changes is a relevant issue. In recent decades, forest vulnerability is rapidly increasing worldwide and forecasting changes in tree health is becoming a challenge. Forest dieback episodes have been recorded in all biomes affecting different tree and shrub species. These dieback cases are revealing the high vulnerability of some species, particularly conifers, manifested as a loss in tree vigour, growth decline and sometimes tree death. Tree mortality commonly involves multiple, interacting factors, ranging from drought to insect pests and diseases, often making the determination of a single cause unrealistic. The need of understanding and predicting changes in tree mortality, growth and recruitment in response to dieback is essential to improve vegetation and C cycle models. Furthermore how adaptive forest management may be applied to improve the resistence and resiliance of forest stands subjected to dieback and mortality events needs to be better understood.
There is a common agreement on the key role of interdisciplinary research and the combined use of complementary tools to improve the monitoring and projection of forest vulnerability and dieback.
This session focuses on efforts to improve our understanding on: i) causes and mechanisms related to forest vulnerability and dieback; ii) potential changes in tree species composition, forest structure and extent of dieback under current and future climate change scenarios; iii) evaluation of which functional anatomical traits and hydraulic properties make some tree species or stands and tree populations more prone to environmental-induced dieback and decline IV) assesment of the role and interaction of insect disease and other abiotic factors on mortality; v) how trees die from drought and how to quantitatively assess tree mortality rates and the magnitude of tree mortality episodes associated to climate change events.
Contributions will focus on an integrated multi-scale (from cells to plant communities, ecosystems and global approaches), multi-temporal (from xylogenesis to long-term forecasting) and interdisciplinary (microscopy and individual Plant physiology to remote) frameworks. Contributions will focus also on modelling the mechanisms or relationships that use climate variability and trends as main drivers for forest planning and management.
