Urban Wild: Reimagining Cities as Living Ecosystems
A peregrine falcon nests on a skyscraper ledge, hunting pigeons among glass towers. Coyotes trot through Los Angeles backyards under cover of darkness. Bees build hives in city walls while butterflies navigate from rooftop garden to pocket park. Cities, often seen as the antithesis of nature, are revealing themselves as complex ecosystems teeming with life. More than half the world’s population now lives in urban areas, a figure expected to reach 68% by 2050. As cities expand, the traditional separation between urban and natural becomes increasingly artificial and counterproductive. The future of conservation isn’t just in distant wilderness—it’s in reimagining our cities as living ecosystems where humans and wildlife coexist and thrive together. At the Rissover Foundation, we support innovative urban conservation initiatives that transform concrete jungles into biodiverse habitats, proving that nature doesn’t end where cities begin.
The Hidden Nature of Cities
Cities harbor surprising biodiversity. New York City hosts over 600 native plant species and 350 bird species. London is home to 13,000 species of wildlife. San Francisco Bay Area cities support more endangered species than many national parks. This urban biodiversity isn’t just surviving—in some cases, it’s thriving in ways that challenge our assumptions about wildlife needs and adaptability.
Urban environments create novel ecosystems with unique characteristics. Heat islands extend growing seasons. Buildings create cliff-like nesting sites. Stormwater systems become wetlands. Abandoned lots transform into meadows. These aren’t degraded versions of natural habitats—they’re entirely new ecosystem types that support both native species and novel communities of organisms adapting to urban conditions.
The wildlife in our cities isn’t limited to pigeons and rats. Urban areas support everything from apex predators to rare plants, from migrating birds to endemic insects. Some species, like peregrine falcons and monk parakeets, have found cities so suitable that urban populations now exceed those in traditional habitats. Others use cities as crucial stopover sites during migration or as climate refugia when surrounding landscapes become inhospitable.
Why Urban Conservation Matters
Urban conservation is essential for multiple interconnected reasons that extend far beyond city limits:
Biodiversity Protection: As urbanization expands, cities occupy critical locations in landscapes—river valleys, coastal areas, migration corridors. Without urban conservation, these areas become barriers to wildlife movement and population sinks that drain surrounding habitats. By making cities more hospitable to wildlife, we maintain landscape connectivity and support regional biodiversity.
Human Well-being: Access to nature improves physical and mental health, reduces stress, enhances cognitive function, and strengthens immune systems. Children who grow up with regular nature contact show better emotional regulation, creativity, and academic performance. Urban nature provides these benefits to millions who might otherwise have limited access to natural areas.
Climate Resilience: Urban green infrastructure—parks, green roofs, street trees, wetlands—provides crucial climate services. Vegetation cools temperatures, absorbs stormwater, filters air pollution, and sequesters carbon. Cities with robust green infrastructure are more resilient to heat waves, flooding, and other climate impacts.
Environmental Justice: Low-income communities and communities of color often have the least access to green space and suffer disproportionately from environmental hazards. Urban conservation that prioritizes underserved neighborhoods addresses historical inequities while providing health, economic, and social benefits.
Connection and Education: For most people, cities provide their primary opportunities to interact with nature. Urban wildlife watching, community gardens, and restored habitats create connections that inspire broader conservation action. Cities are where we’ll win or lose the battle for public support of conservation.
Designing for Coexistence
Creating wildlife-friendly cities requires rethinking urban design at every scale:
Building Design: Bird-safe glass reduces collisions that kill nearly a billion birds annually in North America alone. Green roofs provide habitat and manage stormwater. Building facades designed with nesting sites support birds and bats. Dark sky-friendly lighting reduces disruption to nocturnal species and migrating birds.
Green Infrastructure: Bioswales, rain gardens, and constructed wetlands manage stormwater while providing habitat. Green streets with native plantings create corridors for pollinators and other wildlife. Urban forests increase canopy cover, moderate temperatures, and support diverse species assemblages.
Parks and Open Spaces: Traditional manicured parks can be reimagined as biodiverse habitats. Native plant gardens support local species. Pollinator meadows replace monoculture lawns. Wetlands and ponds provide breeding habitat for amphibians. Leaving some areas “messy” with dead wood, leaf litter, and tall grass creates crucial microhabitats.
Corridors and Connectivity: Wildlife needs to move through urban landscapes for feeding, breeding, and dispersal. Green corridors along rivers, utility rights-of-way, and transportation routes provide movement pathways. Street trees create canopy connections. Gardens and green spaces act as stepping stones across the urban matrix.
Community-Powered Conservation
Urban conservation succeeds when communities lead. City residents who might never visit national parks become passionate conservationists when they discover the nature in their neighborhoods:
Community Gardens do more than grow food—they create habitats, build communities, and teach ecological principles. Gardens designed with native plants, water features, and diverse structure support surprising biodiversity while providing fresh produce and gathering spaces.
Citizen Science engages thousands of urban residents in monitoring wildlife, tracking phenology, and collecting data that informs conservation decisions. Projects like eBird, iNaturalist, and local bioblitzes transform city residents into scientific contributors while deepening their nature connections.
Schoolyard Habitats bring conservation directly to children. When schools replace asphalt with gardens, ponds, and native plantings, they create outdoor classrooms where students learn through direct experience. These habitats often become neighborhood resources, spreading conservation awareness throughout communities.
Neighborhood Groups organize to create pollinator pathways, remove invasive species, advocate for green space, and monitor local wildlife. These grassroots efforts build social capital while improving urban habitats. When neighbors work together for conservation, they strengthen both ecosystems and communities.
Innovation in Urban Habitats
Cities are becoming laboratories for conservation innovation:
Tiny Forests: The Miyawaki method creates dense, diverse mini-forests that grow rapidly and support high biodiversity in spaces as small as tennis courts. These tiny forests provide habitat, improve air quality, and create neighborhood gathering spaces.
Floating Wetlands: Artificial floating islands in urban water bodies provide nesting sites for birds, improve water quality, and create fish habitat. These innovative structures turn degraded urban waters into functional ecosystems.
Wildlife Crossings: Cities are pioneering wildlife crossing structures adapted to urban contexts—bridges for squirrels, tunnels for amphibians, green overpasses that connect parks across highways. These structures reduce wildlife mortality while maintaining population connectivity.
Vertical Habitats: Living walls, green facades, and vertical gardens create habitat in the vertical dimension. These structures support insects, birds, and even small mammals while cooling buildings and improving air quality.
Pop-up Habitats: Temporary installations in parking spaces, vacant lots, and underused spaces demonstrate conservation possibilities and engage communities. These pop-ups often catalyze permanent habitat creation.
The Challenge of Human-Wildlife Conflict
As wildlife returns to cities, conflicts inevitably arise. Deer browse gardens. Raccoons raid garbage. Coyotes prey on pets. Birds nest in inconvenient locations. These conflicts, if not addressed thoughtfully, can undermine support for urban conservation.
Successful coexistence requires:
Education: Most conflicts stem from misunderstanding wildlife behavior and needs. Education programs that teach coexistence strategies—securing garbage, protecting gardens, supervising pets—prevent problems before they occur.
Design Solutions: Wildlife-proof containers, fencing that allows small animal movement while excluding larger species, and habitat modifications that direct wildlife away from conflict areas reduce negative interactions.
Response Protocols: Clear protocols for responding to wildlife issues, trained personnel who can address concerns professionally, and communication channels that give residents voice in management decisions build trust and support.
Values Integration: Different communities have different relationships with wildlife based on culture, experience, and values. Successful urban conservation respects these differences and finds solutions that work for diverse communities.
Green Gentrification: A Conservation Challenge
One of the most complex challenges in urban conservation is “green gentrification”—when environmental improvements increase property values and displace long-term residents. Communities that have endured environmental injustices for generations may be pushed out just as conditions improve.
Addressing this requires:
Community Ownership: Ensuring that local communities lead conservation planning and implementation, rather than having improvements imposed from outside.
Anti-displacement Measures: Combining conservation with affordable housing policies, community land trusts, and other mechanisms that allow current residents to remain and benefit from improvements.
Equitable Distribution: Spreading green infrastructure throughout cities rather than concentrating it in certain neighborhoods, ensuring all communities have access to nature.
Cultural Integration: Incorporating community cultural values, practices, and preferences into urban nature design, creating spaces that serve local needs rather than generic green space.
Technology and Urban Nature
Technology is opening new possibilities for urban conservation:
Smart Sensors monitor air quality, noise levels, temperature, and wildlife activity, providing real-time data about urban ecosystem health. This information helps identify problems, track improvements, and engage communities.
Apps and Platforms connect people with urban nature. Apps help identify species, locate green spaces, report wildlife sightings, and participate in conservation activities. Digital platforms coordinate volunteer efforts and share resources.
Green Infrastructure Modeling uses advanced computing to optimize placement of green infrastructure for maximum biodiversity, climate, and social benefits. These models help cities invest limited resources most effectively.
Automated Monitoring through camera traps, acoustic sensors, and environmental DNA sampling tracks urban biodiversity with minimal human effort, allowing continuous monitoring across large urban areas.
Policy and Planning for Urban Nature
Effective urban conservation requires supportive policies and integrated planning:
Biodiversity Strategies: Cities like Singapore, Berlin, and Mexico City have developed comprehensive biodiversity strategies that set targets, coordinate actions, and monitor progress. These strategies mainstream conservation across government departments.
Green Building Standards: Requirements for green roofs, bird-safe design, and native landscaping in new developments integrate conservation into urban growth. Incentives for retrofitting existing buildings multiply conservation benefits.
Urban Forest Plans: Comprehensive urban forest management that considers biodiversity, climate, and social benefits rather than just aesthetics transforms city trees from ornaments into functional ecosystems.
Regional Coordination: Urban conservation requires coordination across municipal boundaries. Regional partnerships ensure that urban conservation contributes to landscape-scale connectivity and ecosystem function.
Economic Benefits of Urban Nature
Urban conservation isn’t just an environmental nice-to-have—it makes economic sense:
Property Values: Homes near green spaces command higher prices. Street trees increase property values. Green infrastructure improvements benefit entire neighborhoods economically.
Health Savings: Access to urban nature reduces healthcare costs by promoting physical activity, improving mental health, and reducing exposure to air pollution and heat.
Green Jobs: Urban conservation creates employment in restoration, maintenance, education, and monitoring. These jobs often provide pathways to careers for underserved communities.
Tourism and Recreation: Urban nature attractions draw visitors, support local businesses, and enhance city reputations. Cities known for their green spaces attract residents and businesses.
Ecosystem Services: The air filtration, temperature regulation, stormwater management, and carbon sequestration provided by urban nature represent billions in economic value annually.
Youth and Urban Conservation
Young people growing up in cities often have limited nature experience, but when engaged, they become passionate conservation advocates:
Environmental Education that uses local urban nature as classroom makes conservation relevant and accessible. Students studying their schoolyard ecosystem develop observation skills, scientific thinking, and conservation ethics.
Youth Employment in urban conservation provides job skills, career pathways, and leadership development. Programs that hire youth for restoration, monitoring, and education build the next generation of conservation professionals.
Technology Integration leverages young people’s comfort with technology for conservation. Youth-led social media campaigns, app development, and digital storytelling spread conservation messages to peers.
Environmental Justice resonates strongly with urban youth who experience environmental inequities firsthand. Youth-led environmental justice initiatives combine conservation with social activism.
A Vision for Biophilic Cities

The Urban Conservation Imperative
As humanity becomes increasingly urban, the fate of global biodiversity depends partly on what happens in cities. Urban areas can be barriers that fragment landscapes and drain surrounding habitats, or they can be living ecosystems that support biodiversity while enhancing human well-being.
The choice is ours. By reimagining cities as ecosystems, designing for coexistence, empowering communities, and integrating conservation into urban planning, we can create cities where both people and wildlife thrive. Urban conservation isn’t about choosing nature over people or rurality over urbanity—it’s about recognizing that human and natural communities are inseparable, especially in cities.
The Rissover Foundation supports urban conservation because we believe cities are critical sites for conservation innovation, community engagement, and environmental justice. The conservation solutions developed in cities—collaborative approaches, technological innovations, community-led initiatives—offer lessons for conservation everywhere.
The urban wild is all around us, waiting to be recognized, celebrated, and protected. From the ant colonies in sidewalk cracks to the hawks nesting on skyscrapers, from community gardens to restored wetlands, nature persists in our cities. By nurturing this urban nature, we nurture ourselves, our communities, and our planet.
The future of conservation is urban. Not exclusively, but necessarily. As we build cities for the 21st century and beyond, let’s build them as living ecosystems where the wild hasn’t been banished but welcomed, where conservation happens not in spite of human presence but through it, where every city resident is a potential conservationist. The urban wild is calling. Will we answer?
