Nature-based solutions (NbS) are critical to the sustainable development of urban environments and can vary from landscape-scale interventions such as catchment restoration to small scale actions including green walls and swales. High quality, diverse, green infrastructure in urban areas brings a wide range of benefits, and rees in particular have been shown to boost connection to nature, health and wellbeing and provide vital environmental services. This article describes the implementation, monitoring and upscaling of one urban NbS intervention – Tiny Forest: small patches of woodlands of exclusively native species in urban areas where space for high quality greenspace developments may be limited. The aim of Tiny Forest is to engage communities and local stakeholders in co-designing, co-creating, and raising environmental awareness through the planning, maintenance, education and citizen science monitoring of environmental and social benefits.
