Brief Comments on Common Plant Choices of Bioretention Based on Different Green Infrastructures (GI) Sites Characteristics

Abstract

This article describes the plant selection for Bioretention, a common category of green infrastructure, and how it relates to the functions of bio-retentions. Bio-retentions are type of green infrastructures, focusing on controlling runoffs and then infiltrations with flexible configurations, allowing different plant choices function in different ways, which are briefly commented by this article. Information from a BMP (Best-Management practice) mapping tool, including summary reports about bio-retention sites’ characteristics, rainfall and runoff volume are used as primary source of data in this study. Four sites were selected with relatively integrate summary reports (with enough important information including plant coverage and rate of impervious) and summarized the reports into table form. We compare details through the summary table. Overall, designing and choosing plants for bio-retentions are many-sided, and the existing plant choices fits respective sites’ characteristics. Further research can focus on subjoining parameters and applying statistical models to the summarized dataset.
