Advancements in genetic science and conservation are crucial tools for enhancing the resilience of forest ecosystems against climate change, emphasizing the need for conservation strategies that protect genetic diversity. Strategic management and policy development are imperative to utilize these technologies effectively in conservation efforts, and this is evident in the participation of Greece and Serbia in international organizations, such as the Food and Agriculture Organization (FAO) of the United Nations, the United Nations Environmental Programme (UNEP), and the European Forest Genetic Resources Programme (EUFORGEN). Greece and Serbia are actively engaged within the specified organizations, and as such, their efforts in the conservation of forest genetic resources (FGRs) amidst climate change are structured under the guidance and influence of these stakeholders. Both countries recognize collaborative endeavors between research entities and conservation initiatives and underscore the potential of innovative genetic and biotechnological approaches in FGR management. Genetic monitoring and evaluation play a vital role in pinpointing species and populations at risk and guiding conservation priorities and actions. Examples of successful conservation practices are given both from Serbia and Greece, illustrating that combining traditional methods with modern genetic insights is key to sustaining forest ecosystems. Such comprehensive approaches are essential in countering the adverse effects of climate change on forests, thereby contributing to the conservation of global biodiversity and the stability of natural environments.
