While research suggests bioretention and wetland environments are important, it also suggests that they may lack visual interest. Understanding perceptions of bioretention seasonality may improve planting design. This study explored perceptions of seasonal change in bioretention practices. Respondents in the Southeastern Coastal Plain, USA, (n=985) replied to an online survey comparing actual photos of five different bioretention sites taken throughout the year. The photo-based discrete choice experiment (DCE) captures the decision making process by estimating weighted factors based on the respondents’ chosen preferences. Unsurprisingly, results revealed a preference for the growing season over the dormant season (X2 (4, n = 985) = 928.490, p<0.01) and suggested specific design recommendations to improve the visual appreciation of bioretention practices, such as intentional year-round seasonal planting design.
