WHAT THE EVIDENCE SAYS
Across 60 patches, researchers counted 2,896 birds of 114 species. Models for 46 species often linked bird abundance to within-patch bog vegetation and tall graminoids; area also mattered.
WHY IT MATTERS / OUR READ
Maintain vegetation heterogeneity when conserving working-land grasslands rather than relying on total hectares.
CAVEATS / UNCERTAINTY
Observational guild-specific associations cannot establish how grazing or restoration changes populations elsewhere.
