Evidence

Peer-reviewed

Geography

Haidian District, Beijing, China; 40 permanent plots in 22 subdistricts

System

Urban biodiversity and carbon-function indicators

## WHAT THE EVIDENCE SAYS

From 2014–2025, monitoring at 40 permanent quadrats showed higher recorded plant richness and rising observed bird species counts, alongside a composite biodiversity index associated with urban carbon-sink estimates in mixed models. The authors note that improved acoustic detection contributed to the sharp rise in recorded bird diversity after 2023.

## WHY IT MATTERS / OUR READ

Cities should measure species and ecological quality, not mistake greener area alone for function. The key distinction is between a biodiversity–carbon association and proof that adding biodiversity caused a measured amount of sequestration.

## CAVEATS / UNCERTAINTY

Single-district observational panel; biodiversity detection methods improved through time, and reported sink capacity involves estimates. Covariate adjustments do not exclude unmeasured urban management or policy confounders.
