RESUMO
The vegetation and soil microbiome within urban green spaces is increasingly managed to help conserve biodiversity and improve human health concurrently. However, the effects of green space management on urban soil ecosystems is poorly understood, despite their importance. Across 40 urban green spaces in metropolitan Adelaide, South Australia, we show that soil bacterial communities are strongly affected by urban green space type (incl. sport fields, community gardens, parklands and revegetated areas), and that plant species richness is positively associated with soil bacterial diversity. Importantly, these microbiome trends were not affected by geographic proximity of sample sites. Our results provide early evidence that urban green space management can have predictable effects on the soil microbiome, at least from a diversity perspective, which could prove important to inform policy development if urban green spaces are to be managed to optimise population health benefits.
