Socio-economic inequalities in access to nature on public and private lands: A case study from Brisbane, Australia

Opportunities to experience nature are important for human wellbeing, yet they are often inequitablydistributed across society. Socio-economic variation can explain some of this inequity, but there has beenrelatively limited consideration of how access to different kinds of nature experiences varies across society. Here we examine how tree cover (as a measure of the general 'greenness' of urban environments) andnative remnant vegetation cover (as a measure of access to higher quality natural areas) varies acrossthe socio-economic gradient within public parkland and residential yards in Brisbane, Australia. Wefound that most tree cover was provided on residential land, and spatial regression models revealed thattree cover in both public parkland and private spaces was strongly positively related to socio-economicadvantage. Conversely, most remnant vegetation cover was located on public parkland, and this wasonly weakly positively related to socio-economic status. These results suggest that municipal management of remnant vegetation can support equity in access to high quality nature experiences across thesocio-economic gradient. However, the results also highlight the important role of residential yards inproviding access to nature in general, as these areas provide the majority of overall tree cover. Thus,while public policy can enhance equity in access to nature on public lands, strategies such as social marketing and incentives that enhance nature within private spaces are important particularly within moredisadvantaged neighbourhoods.
