Sustainable urban development advocates integrating biodiversity into the built environment. It aims to ensure that plant and animal communities remain resilient not as immaculate lawns and potted plants but as biodiverse ecosystems that offer ecological services.

Biodiverse green spaces, green roofs, natural waterways, bio-corridors, eco-brutalist architecture, etc, typify sustainable urban landscapes. 

To achieve that, city authorities mandate the conservation of high-value ecosystems home to critical or endangered species. They also ensure that green spaces are occupied by appropriate native vegetation that supports pollinators and small animals.
