Abstract
This study provides new information on the influence of vegetation type on the infiltration rate and removal of nutrients in biofilters. Compared to previous studies, a wider range of plant species (11 species native to Western Australia, and 11 native to Victoria) and plant types (lawn grasses, grasses, sedges, rushes and shrubs) were examined in a laboratory-column study. The preliminary results indicate that the presence and type of vegetation influence infiltration rate and nitrogen removal in biofilters. In the early stages of the experiment, vegetation reduced the infiltration rate of columns as compared to soil-only controls, but over time this trend began to change, with. Importantly..
