Climate Signals for Growth Variations of F. sylvatica, P. abies, and P. sylvestris in Southeast Germany over the Past 50 Years

Since recent drought events have already caused severe damage to trees and droughts in the near future are expected to occur even more frequently, this study investigated the response of forest ecosystems to changing climate conditions in the topographically complex region of Bavaria, southeast Germ...

In conclusion, all studied tree species were affected by drought events, even at humid high-elevation sites. Correlations with daily climate variables confirmed that even short-term weather conditions could strongly influence trees’ radial growth. Tree responses to climate conditions have shifted significantly between past and present periods but vary considerably among sites and are generally stronger in humid regions than in already dry areas.Annette DebelWolfgang Jens-Henrik MeierAchim BräuningMDPI AGarticletree-ring widthsclimate–growth relationshipsforest dynamicsclimate variabilityextreme climatic eventsBavariaPlant ecologyQK900-989ENForests, Vol 12, Iss 1433, p 1433 (2021)
