As urbanization intensifies, communities encounter increasing challenges in designing, planning, and managing urban green spaces. Co-design offers a just and participatory approach that can unite diverse interest-holders to identify challenges and devise transformative solutions to complex urban issues such as green space governance. However, while co-design is acknowledged for its potential to foster learning and systemic change, it largely remains anthropocentric, often overlooking multispecies perspectives in planning, policy, and academia. We present a case study from New York City that examines how a multispecies co-design approach may enhance social-ecological systems transformation by exploring participants’ learning experiences and perceptual shifts. The paper begins by exploring the literature on co-design and multispecies thinking within social-ecological systems and their contribution toward transformations, establishing the conceptual groundwork for integrating non-human actors into urban planning. We then present a case study of a multispecies co-design process in New York City and explore how engaging with it contributes to systems transformation. Findings from the case study reveal key motivations for participation, drivers of learning during the process, and emergent transformative solutions. By analyzing these dynamics, this research illustrates how co-design, which integrates multispecies perspectives, may refine ecological decision making and encourage deeper engagement with urban nature. The study argues that integrating multispecies approaches into co-design practices is essential for fostering sustainable societies. The paper concludes with guiding principles for researchers and practitioners seeking to implement inclusive co-design processes in social-ecological systems, particularly in complex urban environments such as New York City. Non-Technical Summary As cities grow, it becomes more difficult for communities to design and care for green spaces in ways that work for everyone. Co-design is a collaborative approach that brings different people together to identify problems and create shared solutions, but it usually focuses only on human needs. This paper explores how including non-human life, such as plants and animals, in co-design can lead to better outcomes for both people and nature. Using a case study from New York City, the research looks at how a multispecies co-design process changed how participants thought, learned, and acted in relation to urban green spaces. The findings demonstrate why people chose to participate, how learning occurs during the process, and how new, more sustainable ideas emerge. Overall, the study shows that designing cities with both humans and other species in mind may support healthier urban ecosystems and more engaged communities, offering practical guidance for doing this in complex urban settings.
