Contrasting Drought Sensitivity in Silver Fir and Scots Pine Revealed Through Growth and Wood Density Data

Popis výsledku v původním jazyce

Understanding species-specific drought responses is critical to predict forest resilience under climate change. We investigated how series of secondary growth, earlywood (EWD) and latewood (LWD) density of silver fir (Abies alba) and Scots pine (Pinus sylvestris) responded to climate variability from 1952 to 2020. We sampled three sites across a climatic gradient in the southwestern Pyrenees, obtaining density values from declining silver fir and from non-declining Scots pine individuals. We assessed climate-growth/density relationships and drought resilience indices to extreme drought events. Silver fir exhibited more conservative growth patterns and a negative relationship between EWD and water availability from prior winter to spring in drier sites, suggesting priority resource allocation to hydraulic safety. In contrast, Scots pine displayed declining growth trends and a similar response of EWD to spring water availability, suggesting a drought-avoidance strategy. Resilience analysis following major droughts (1986, 1998, 2005, and 2011) revealed contrasting patterns. In silver fir, drought resilience was more dependent on resistance (Rt) in wet sites and recovery (Rc) in dry ones, while EWD resilience was consistently explained by Rt across populations. This study, though based on three sites with limited wood density data, underscores the vulnerability of silver fir near its southern distribution limit and the importance of integrating growth and xylem traits to capture species- and site-specific responses to drought in mountain forests.
