Evidence-based urban greening: a missing piece in biodiversity conservation
With calls for increased greenery in cities to safeguard biodiversity and its associated benefits to humans, urban vegetation must be managed carefully and efficiently. It is time to change paths from current spurious attempts to manufacture resilience and instead usher in evidence-based urban greening to secure ecosystems for the future.
