This paper investigates the role of plants in bioretention systems and their influence on hydraulics and pollutant attenuation. This study examines plant-media interactions and rhizosphere processes, with a focus on system resilience and clogging risk in a bioretention system. An existing bioretention system, collocated within a regional detention basin called Basin F6.1 in The Ponds, New South Wales (Blacktown City Council local government area) was used as a preliminary case study. Six cells are being monitored to explore how plant traits such as density, growth, and health could affect rates of infiltration and evapotranspiration, soil moisture, and pollutant removal. The future research directions may include longitudinal monitoring of plant health linked to performance metrics across multiple years, development of predictive models incorporating plant health, sediment dynamics, and hydraulic conductivity; field trials of alternative planting strategies and maintenance interventions to enhance resilience and impact of seasonality and climate change on plant dynamics. The ongoing study will provide additional insights into the performance of the plants in this Council owned and maintained bioretention system.
