Impacts of warmer temperatures on the above- and belowground system of four economically important timber species

A recent study reveals significant species-specific responses of four major timber species to warmer temperatures, highlighting the vulnerability of conifers compared to broadleaved species. Research comparing forest stands in northern Germany and the Upper Rhine Valley—where mean annual temperatures are 2°C higher—found that European beech (Fagus sylvatica) and sessile oak (Quercus petraea) showed increased sensitivity to water stress, while Scots pine (Pinus sylvestris) and Douglas fir (Pseudotsuga menziesii) exhibited stronger negative responses to summer heat. Belowground, fine root biomass and productivity declined for beech, pine, and Douglas fir in the warmer region, whereas oak remained resilient with trends toward increased productivity and longevity. The study underscores the need for adaptive forest management strategies to enhance resilience under climate change.
