London Met sustainability expert shares insights on rewilding cities during BBC Radio 4’s environmental series
Date: 13 January 2026
Associate Professor Siân Moxon appeared on BBC Radio 4’s Rare Earth on 12 December to discuss how urban spaces can support biodiversity and improve well-being. The episode, titled Hiding in Plain Sight, explored the hidden richness of urban wildlife and how cities can become vital habitats rather than biodiversity deserts.
Sian, founder of the Rewild My Street initiative, explained how simple design changes—such as planting native species, creating green corridors, and reducing hard landscaping—can transform urban areas into thriving ecosystems. She highlighted the ecological and social benefits of rewilding, from boosting mental health and reducing pollution to tackling climate challenges.
“Cities don’t have to be barren landscapes for wildlife. With small changes, we can make urban areas part of the solution,” she said. “Rewilding isn’t just about ecology; it’s about people. Seeing nature return to our streets creates a sense of connection and pride.”
The discussion emphasised that biodiversity loss is not just a rural issue. Urban areas, often overlooked in conservation strategies, can play a crucial role in supporting species and mitigating climate impacts. Moxon’s approach encourages residents to take action by making gardens and streets wildlife-friendly, fostering community engagement and resilience.
Her work through Rewild My Street aligns with London Metropolitan University’s commitment to sustainability and innovation. The initiative provides practical guidance and resources for homeowners and city planners to integrate nature into built environments, demonstrating that rewilding is achievable at every scale—from individual gardens to entire neighbourhoods.
Sian’s appearance on Rare Earth underscores the growing movement to rethink urban design in response to the climate and biodiversity crises. By championing greener cities, she advocates for a future where urban living and wildlife coexist harmoniously.
