英文摘要	The Rhine River valley of Germany has been facing recurrent and intense spells of drought and heatwaves threatening the health of trees in peri-urban forests. Crown damage intensified by climate change accelerates tree mortality, threatening its ecological, economic, and social benefits; however, the pattern of crown die -back in peri-urban forests remained unclear. We performed a field inventory to estimate the crown die -back of 2578 trees of 51 species from 68 randomly selected peri-urban forest plots in Karlsruhe region on the right bank of the Rhine, after the catastrophic summer heatwave and drought of 2018. We related crown die -back to speciesspecific drought tolerance, wood anatomical traits, tree size, canopy surface temperature, tree density, Shannon's diversity and Gini coefficient for tree height. Regression results indicate that small -size trees were found to be more susceptible to canopy damage than large trees, with a 1 -meter increase in tree height associated with a 0.8 % reduction in crown die -back. This size -dependent process is also species -specific. Among the 12 species with significant (p < 0.05) linear relationship between height and die -back, 9 species demonstrated negative correlations and 3 species showed positive relationships. Species tolerant to drought or cavitation (e.g., trees with diffuse porous xylem, 21 species) had significantly lower crown dieback. For example, with a 1 -point -scale Contents lists available at ScienceDirect Science of the Total Environment
