# Urban green space: quantity, condition and ecological performance

- Description: The global urban-bird study above is the strongest empirical piece: the ecological performance of urban green space appears related to both how much exists and what condition it is in, which is much closer to landscape-architecture thinking than the common “percent canopy” metric alone.

## WHAT THE EVIDENCE SAYS

The global urban-bird study above is the strongest empirical piece: the ecological performance of urban green space appears related to both how much exists and what condition it is in, which is much closer to landscape-architecture thinking than the common “percent canopy” metric alone.

## WHY IT MATTERS / OUR READ

The global urban-bird study above is the strongest empirical piece: the ecological performance of urban green space appears related to both how much exists and what condition it is in, which is much closer to landscape-architecture thinking than the common “percent canopy” metric alone.

## CAVEATS / UNCERTAINTY

The global analysis reports associations and modeled greening scenarios. It does not show that every greening project will deliver the same bird or cooling response.

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