The I-Tree suite of tools is the “Swiss Army Knife” of urban forestry. It can do just about anything – from calculating the benefits of planting a single tree on a specific site to estimating your community’s overall tree canopy and monetizing the ecosystem services it provides. Thousands of users have proven the old adage: money talks. As Mayor Frank Cownie of Des Moines put it: “Trees are my most productive and inexpensive ‘employees.’ They work 24/7, provide economic, environmental and social value – and never take vacations.”
I-Tree tools make a powerful case for expanding urban forestry programs on public and private land. Be sure to visit I-Tree to learn how to use these tools:
I-Tree Canopy uses aerial images from Google Maps to produce a statistically valid calculation of land cover types, including tree cover. The latest version also estimates values for air pollution reduction and capturing atmospheric carbon. I-Tree Canopy can also be used to estimate inputs for use in I-Tree Hydro and elsewhere where land cover data are needed, and monitor canopy change over time.
I-Tree Eco uses field data from complete inventories or randomly-located plots throughout a community along with local hourly air pollution and meteorological data to quantify urban forest structure, environmental effects, and values to communities.
I-Tree Streets uses a sample or complete inventory to quantify and put a dollar value on street trees’ annual environmental and aesthetic benefits.
I-Tree Hydro estimates the effects on stream flow and water quality within a watershed by simulating changes in tree cover and impervious surfaces.
I-Tree Vue links to National Land Cover Database (NLCD) satellite-based imagery to assess your community’s land cover, including tree canopy, and some of the ecosystem services provided by your current urban forest. NLCD data are available without charge. This tool also models how different planting scenarios can affect future ecosystem benefits.
I-Tree Design links to Google Maps and allows you to see how tree selection, tree size, and placement around your home – or any other site — affect energy use and other ecosystem benefits.
I-Tree Species is a free-standing utility designed to help urban foresters select the most appropriate tree species based on environmental function and geographic area.
I-Tree Pest Detection Module is a portable, accessible and standardized protocol for observing a tree for possible insect or disease problems. This module is currently available within I-Tree Streets and I-Tree Eco programs.
I-Tree Storm provides a method for a community to assess widespread storm damage in a simple, credible, and efficient manner immediately after a severe storm. It is adaptable to various communitytypes and sizes and provides information on the time and funds needed to mitigate storm damage.
