Here, we summarize recent work describing and quantifying the stormwater management benefits of trees, especially at the individual tree and property/site scales.
Review of the Available Literature and Data on the Runoff and Pollutant Removal Capabilities of Urban Trees
The Center for Watershed Protection reviewed a total of 159 publications to evaluate the research questions defined in the scope of this project: 1. What is the effectiveness of urban tree planting on reducing runoff, nutrient and sediment, and 2. How does effectiveness vary by species, over time, with differences in planting sites (e.g., distance from impervious cover or other trees, soil conditions, geographic location) and with different maintenance strategies.
The Role of Trees in Urban Stormwater Management
Arboriculture deserves additional consideration as a stormwater control measure. The reliable use of trees for stormwater control depends on improved understanding of how and to what extent trees interact with stormwater, and the context-specific consideration of optimal arboricultural practices and institutional frameworks to maximize the stormwater benefits trees can provide.
