Boreal tree species diversity increases with global warming but is reversed by extremes

Y. Xi, W. Zhang, et al.

This study, conducted by Yanbiao Xi and colleagues, reveals that boreal tree species diversity surged by 12% from 2000 to 2020, driven by rising temperatures. However, extreme warming takes a toll, negatively impacting diversity in certain areas. Discover how this increased diversity interplays with forest productivity and stability.

Abstract
This study investigates the impact of climate change on boreal tree species diversity, productivity, and ecosystem stability. Using field observations and Landsat imagery, the researchers found a 12% increase in tree species diversity from 2000 to 2020 across 53% of boreal forests. This increase is positively correlated with rising temperatures, but this relationship weakens with more extreme warming. Areas experiencing extreme warming (>0.065 °C yr⁻¹) showed a negative impact on diversity. The increased diversity is significantly associated with higher productivity and temporal stability of boreal forest biomass.
