A study used 12 under-drained, experimental bio-retention water enclosures to gauge the effects of plants and microorganisms on the long-term treatment efficacy of bio-retention for stormwater management in the Pacific Northwest. Results pointed to the importance of physical and chemical variations and suggested further research on the use of fungal-inoculated mulch as a means to curb phosphorous leaching from soils.

A UK study provides initial estimates of the percentages of suspended sediments and phosphorus loads that are likely to be trapped by "Natural Based Solutions" added to small catchments to enhance their natural attenuation. Results from the modeling used indicated that 5% to 10% improvements are possible after adding about 2,600 to 10,400 cubic yards of storage.
