The number of publications on urban ecosystem services (ES) has increased dramatically in recent years. While numerous studies have investigated ES provision from the public realm (e.g., public green spaces, urban parks and reserves, streetscapes) (Lovell & Taylor, 2013), fewer have explicitly accounted for the provision of public ES from residential gardens and, more generally, the private realm (e.g., Cameron et al., 2012; Larson et al., 2015). This article will highlight some major opportunities and limitations regarding the private provision of public ecosystem services (PPPES) in order to offer some stimuli for further research and facilitate interactions between researchers and urban practitioners interested in ES provision.
