Conserving forest genetic resources (FGR) is crucial for forest ecosystems and people's well-being. Populations of species at the edges of their distributions, known as marginal/peripheral (MaP) populations, may contain unusual adaptive traits that make those populations able to survive in marginal environments. The Mediterranean region is subject to highly variable climatic regimes and is characterized by the presence of forest tree populations with high levels of marginality and differentiation. The ranges of many species worldwide are shifting to higher latitudes and elevations in response to climate change. The limits of species ranges have not been sufficiently studied, and the need for long-term conservation of the genetic diversity of MaP populations remains underestimated. Information on FGR is needed to prepare and implement conservation strategies at the national and regional levels.
