## WHAT THE EVIDENCE SAYS

Researchers combined bird observations, remote sensing and environmental data across 1,039 cities worldwide. Cities with more or higher-quality green space were associated with 23–34% lower extreme-heat exposure for birds. Their scenarios suggested that adding green cover equivalent to roughly 5–10% of urban area produced the largest reductions, while higher-quality green space was also associated with greater bird diversity. Across cities, the modeled greening scenarios corresponded to roughly 2–3% higher bird diversity.

## WHY IT MATTERS / OUR READ

Two things make this more interesting than another “parks are good” paper. First, the analysis distinguishes the amount of urban green from its quality. Second, it treats wildlife exposure to urban heat as a spatial ecological process rather than merely counting species inside park boundaries. For landscape practice, designed land becomes ecologically meaningful when its configuration and condition measurably alter environmental exposure.

## CAVEATS / UNCERTAINTY

This is a large observational association, not evidence that planting a specified number of trees in a particular neighborhood will cause a 23–34% reduction. City morphology, climate, vegetation type, management and socioeconomic conditions will affect local outcomes.

Ecological outcomes depend on context: the intervention, the place, the system and the timescale.
