| + | ** Daneis ''et al''. (2018), test the four major hypotheses regarding the role of plants in bioretention systems by reviewing current scientific literature - these are: (1) Planted systems are more effective vs. unplanted ones, (2) Effectiveness of plant species in a bioretention system differ, (3) Native species are more effective vs. their exotic counterparts, and (4) A diverse plant system in bioretention are more efficient vs. the option of planting a monoculture system. |

| + | ** Grey ''et al''. (2018), conduct a streetscape experiment to determine the runoff retention rate of tree pits in heavy [[Soil groups|clay soil]] with low exfiltration nates. Their research found that runoff retention is possible in even very dense urban streetscapes, but sizing of the features must be set between 2.5% - 8% of the impervious catchment area (dependent upon tree pit exfiltration rates) to achieve 90% reduction in annual runoff. |
