Trees and Stormwater Benefits

I came across a new article from Columbia University that added some additional insight into how trees can help mitigate storm water. A recent study by Columbia University showed that trees in an urban/city setting that were planted and protected by a tree barrier, grate, fence etc. had a greater capacity to absorb storm water than those that did not. In fact the study showed that trees were 6 times more effective in absorbing storm water runoff when protected by barriers. This makes perfect sense as compacted soil(s) and a compacted root area is less permeable to water than an un compacted area. So its not just planting trees but protecting their planting space itself that leads to an increase in storm water mitigation. Interesting read for sure and if you would like to see the full article please follow the below web link:
