Introducing oak species for forest resilience in the right-bank Forest-steppe of Ukraine.

Abstract

The article addresses the loss of economically valuable tree species due to climate-driven pests and diseases, such as ash dieback (Fraxinus excelsior) and Dutch elm disease (Ulmus L.). It proposes proactive strategies for preserving Ukraine‘s forests, particularly through the introduction of oak species (Quercus L.) from various floristic regions. Special attention is given to the generative capacity of oaks, seed quality, and adaptability to environmental stressors. The study highlights the potential of Quercus rubra and Quercus castaneifolia in enhancing forest productivity and resilience. The findings underscore the importance of bio-ecological research, high-quality planting material, and innovative approaches to maintaining forest biodiversity amid climate change.
