iTREE is an urban and rural forest management land use suite of models designed to quantify the benefits provided by area trees. Benefits are quantified based on carbon sequestration, pollution reduction, water retention and urban heat island effects.

Spatial Resolution
Spatial resolution ranges from the individual tree to state forest scale.
Temporal Resolution
The temporal resolution is most often given in hours. There are year projections as well.
Outputs include storm water retention and quality, energy savings, urban heat island impacts, pollution mitigation and carbon storage potential.
