Currently the Minimal Impact design Standards (MIDS) calculator is being designed to incorporate volume reductions based solely on storage and infiltration within tree boxes or tree trenches. Readers may refer to [[Bioretention|bioretention]] or [[Green roofs|green roof]] sections of the manual for more information on volume reductions based on storage and infiltration.
 
  
The manual will be expanded to include detailed information on canopy interception and evapotranspiration loss from trees. For now, readers may find information on these topics at the following sources.

Green Infrastructure: Trees can be an important tool for retention and detention of stormwater runoff. Trees provide additional benefits, including cleaner air, reduction of heat island effects, carbon sequestration, reduced noise pollution, reduced pavement maintenance needs, and cooler cars in shaded parking lots.
Information: Tree trenches and tree boxes are bioretention practices. However, because of differences in design, construction and maintenance, we have created a separate section for trees.

Use of trees to manage stormwater runoff encompasses several practices. Tree trenches and tree boxes (collectively called tree BMPs), the most commonly implemented tree BMPs, can be incorporated anywhere in the stormwater treatment train but are most often located in upland areas of the treatment train.

Tree BMPs are one component of urban forestry. Urban forestry is a broad term that applies to all publicly and privately owned trees within an urban area, including individual trees along streets and in backyards, as well as stands of remnant forest (Nowak et al. 2001). This page includes three sections covering general information about trees, tree trenches and tree boxes as BMPs, and urban forestry.
