The COST Action CLEANFOREST organizes its first Training School on “Monitoring spatiotemporal changes in global change drivers and their effects on semiarid woodlands and forests”, which will be held in Lisbon (Portugal) on May 6-9, 2024. Through theoretical sessions and practical workshops, participants will learn about different monitoring methods and parameters used to assess ecosystem fluxes, tree physiology, mortality, and regeneration. Additionally, participants will delve into the biodiversity and functional ecology of plants, including lichens and bryophytes, and their relationship with air quality. The training will also cover soil-related aspects, including the characterization of forest soils and their physico-chemical properties. Through case studies and a field trip to a woodland, participants will apply their knowledge in real-world scenarios, conducting measurements and assessments in different grazing management settings to understand the effects on tree growth, biodiversity, soil decomposition and physico-chemical properties. Finally, participants will engage in data treatment and analysis, synthesizing their findings to draw conclusions and recommendations for sustainable forest management in the context of global change.
