The Ecology for Health guide is based on an extensive review of ecological literature on the potential of cities to support native plants and wildlife, as well as research exploring the health benefits of access to biodiverse greenspace. Anyone making decisions about land use and urban design in cities across the world can benefit from the recommendations in this guide (including community-based organizations, local non-profits, local leaders and policymakers, city planners, urban designers, landscape architects, engineers, gardeners/horticulturists/arborists, residents, and landowners).
