Head Tymoshenko Liudmyla M., Registration Date 01-02-2026 Organization Institute of Agroecology and Environmental Management of National Academy of Agricultural Sciences of Ukraine popup.description1 The aim of the project is to assess the stocks of dead wood by components and species composition in the planting of major forest species in the context of climate change under the Paris Agreement. popup.description2 The research demonstrates that climate change has a significant negative impact on the resource potential of forest stands in Ukraine. An increase in the frequency of years with pronounced water stress is expected, leading to reduced forest productivity and vitality, as well as intensified abiotic disturbances (forest fires, wind damage, and altered soil hydrological regimes) and biotic disturbances, including pest and disease outbreaks. The main functions of coarse woody debris in forest ecosystems were identified, showing that their expression depends on both quantitative and qualitative characteristics, such as fraction, species composition, size, volume, and degree of decomposition. The stocks of standing and downed deadwood were assessed in forest stands of different composition and age, and a clear relationship between deadwood accumulation and site trophic conditions was revealed. These findings are consistent with previous studies and confirm the ecological importance of deadwood. Carbon stocks sequestered in woody debris components were quantified for forest ecosystems of the Middle Right-Bank Dnipro Region, where a substantial proportion of carbon is stored in standing and downed deadwood, highlighting the role of coarse woody debris in the forest carbon balance. Overall, climate change is expected to affect the distribution of forest-forming species, forest structure, productivity, and biodiversity. Although increased atmospheric CO₂ concentrations may enhance forest carbon sequestration, this effect is limited by temperature, precipitation, and nutrient availability. The developed framework of climate change impacts provides a scientific basis for further assessments and the development of adaptation measures in forest management.
