Senior student Cameron has been studying the environment and the effects trees have on the environments. The objective of the lesson was to give students the perspective on how trees benefit their community. Students gathered data and make scientific observations on a variety of tree specimens. Cameron utilized a GPS system to determine the longitude and latitude of the different trees. He measured the diameter of the tree and determine its overall condition. Then using a tree benefits calculator, he determined the value of the tree and is benefit value and percentage.

The Tree Benefit Calculator allows anyone to make a simple estimation of the benefits individual street-side trees provide. This tool is based on i-Tree’s street tree assessment tool called STREETS. With inputs of location, species and tree size, users will get an understanding of the environmental and economic value trees provide on an annual basis.

The Tree Benefit Calculator is intended to be simple and accessible. As such, this tool should be considered a starting point for understanding trees’ value in the community, rather than a scientific accounting of precise values.
