    Landscape and urban planning (Elsevier, 2026)
    Urbanization has led to a significant reduction in green spaces, altering microbial habitats and potentially contributing to the growing prevalence of immune-mediated diseases. Urban greenery may serve as a reservoir for more diverse environmental microbiota, yet the links between street-level vegetation and environmental microbial diversity remain poorly understood. This study investigates how the visibility of greenery, measured through the Green View Index (GVI), relates to microbial richness and Shannon’s diversity across urban habitat gradients in the Taipei metropolitan area. Environmental DNA samples and Google Street View panoramas for calculating GVI were collected from three sublocation types: biodiversity hotspots featuring urban green spaces, residential building entrances, and pavements linking biodiversity hotspots and entrances. Our findings show that biodiversity hotspots support greater microbial diversity, and significant GVI–microbial correlations occur only in biodiversity hotspots, not in pavements or entrances. This positive correlation observed in biodiversity hotspots suggests that street-level vegetation can reflect the diversity of environmental microbial communities. These results highlight the importance of incorporating green infrastructure into urban planning to enhance microbial habitat heterogeneity and promote microbial diversity. As urbanization continues to sever citizens’ contact with nature, this initiative helps maintain the environmental microbiota essential for immune regulation and support public health. Future research should incorporate longitudinal and cross-seasonal studies to evaluate the durability of GVI-microbial relationships, examine the influence of vegetation types and structural complexity, and explore how urban greenery can act both as a scientific indicator and a public engagement tool in biodiversity-aware urban design.
  • Sustainable rewilding of urban spaces increases microbial diversity

    Sustainable microbiology : 2 (Oxford University Press, 2026)
    Soil sealing and biodiversity loss are major drivers of altered microbial communities in urban environments. Little is known about how rewilding reshapes these communities and enriches surrounding sealed surfaces with microbiota. To fill this gap, we first tested whether existing urban green spaces are associated with increased microbial diversity and abundance beyond their boundaries on adjacent impermeable surfaces. We then rewilded a barren, sealed city square using vegetation, compost-based growing medium, and decaying wood. We hypothesized that proximity to green spaces predicts microbial communities more than geographic location, and that rewilding enriches bacterial diversity on nearby sealed surfaces, with diminishing effects across distance. Microbial samples were collected from five green spaces at 0–100 m distances, and from the rewilded and a neighboring non-rewilded square before and after rewilding. In the green space experiment, bacterial richness and relative abundance of Rhizobacter declined steadily with distance from green spaces. In the rewilding experiment, bacterial alpha diversity increased compared to baseline conditions and co-occurrence networks contained more nodes and connections post-rewilding. These findings demonstrate that existing green spaces are associated with elevated microbial diversity on surrounding sealed surfaces, and that rewilding urban areas provides a low-cost, nature-based strategy to increase urban microbial diversity.
