Short summary

Riparian grey alder forests play a key role in carbon and water cycling, yet their response to climate extremes is understudied. Ecosystem flux data show that a mature alder forest remained a strong net carbon sink even during the 2018 drought, with increased spring uptake, reduced summer respiration, enhanced water use efficiency, and suppressed canopy conductance, demonstrating notable drought resilience.
