Can wild urban woodlands be integrated into urban green infrastructure? Insights from urbanites and new urbanites in Chongqing, China

Wild urban woodlands (WUWs) are a novel category of urban forests and have been established as vital sources of diverse ecosystem services for local residents. Despite their potential to mitigate green gentrification, WUWs are often neglected in urban planning. Assessing whether different groups of residents accept WUWs as a part of urban green spaces and determining their preferred WUW type are critical for cities lacking green space supply. Therefore, a collection of photographs of 15 WUW patches was employed in this study to explore the preferences and attitudes of urbanites (n = 200) and new urbanites (i.e., individuals who have undergone a transition from rural to urban residency due to urban expansion; n = 206) toward five prevalent WUW categories and examine their perspectives on the future transformation of these WUWs. Accordingly, the following study results were obtained. (1) New urbanites exhibited greater support for integrating WUWs into urban green infrastructure compared to urbanites, primarily due to the limited supply of green spaces in their residential surroundings. (2) The one-way ANOVA shows significant differences in WUW preference scores between new urbanites and urbanites. Urbanites strongly preferred WUWs situated within stream corridors and the least for WUWs in urban villages. Conversely, new urbanites preferred WUWs on agricultural lands and found WUWs on industrial lands the least appealing. (3) Most participants expressed a desire to witness the planned transformation of WUWs. New urbanites preferred additional spaces for leisure activities, whereas urbanites hoped to witness visual improvements in the WUWs. (4) Multifactor ANOVA shows rural background significantly affects preferences scores. Spearman correlation indicates terrain ruggedness and surrounding construction intensity relate to preference. These findings underscore the substantial potential of WUWs in the urban greening in China. They contribute to urban managers' understanding of the diverse needs of the two urban resident groups regarding WUWs, thereby fostering equity in green space planning.
