Where i-Tree Streets Is Used

Davis, CA (May 4, 2010)- Within i-Tree, street tree populations are assessed using Streets (formerly STRATUM). Streets is a street tree management and analysis tool for urban forest managers that uses tree inventory data to quantify the dollar value of annual environmental and aesthetic benefits: energy conservation, air quality improvement, CO2 reduction, stormwater control, and property value increase.

It’s an easy-to-use, computer-based program that allows any community to conduct and analyze a street tree inventory. Baseline data can be used to effectively manage the resource, develop policy and set priorities. Using a sample or an existing inventory of street trees, this software allows managers to evaluate current benefits, costs, and management needs.
Here are some examples from around the country where i-Tree Streets is being used:
New York: i-Tree i-Phone Application Details NYC Street Trees
A new application named Trees Near You helps NYC residents identify and discover the benefits of the more than 500,000 trees on NYC’s streets, one tree at a time. A map with dynamic zoom from borough, through block, and down to streets, identifies trees using street tree census data publicly released by the city government. The species, diameter, carbon storage, energy savings, and stormwater gallons intercepted are given for the trees displayed on screen. More information on the types of trees is given through a link to Wikipedia.

Indiana: Guarding Against Catastrophic Losses from Pests and Disease
The Indiana Dept. of Natural Resources, Division of Forestry, Community and Urban Forestry statewide sample inventory project combined 23 communities’ tree populations to assess the species distribution across the state’s streets. Results showed a single species, silver maple, composed 18 percent of the total population and provided 27 percent of the total benefits, or $7.0 of $30 million, as calculated in i-Tree Streets. Indiana is seeking to increase species diversity to guard against future catastrophic losses of these benefits.

Texas: i-Tree Streets Used for Trees in Turtle Creek Greenbelt, Dallas, TX
Texas Forest Service Regional Urban Forester, Micah Pace, sent us his report on tree resource analysis using i-Tree Streets to analyze the trees of Turtle Creek Greenbelt in Dallas. The study surveyed all trees four inches and greater. The report was released in March, 2010 and found they provided ecosystem services valued at $183,492 and average $70.52 per tree.

California: a New Web Based Program Called Urban Forest Map is Launched
San Francisco is the first city to use the Urban Forest Map, a new online tool developed by the California Department of Forestry and Fire Protection in cooperation with Friends of the Urban Forest (FUF) and the City of San Francisco to catalogue the city’s leafy assets. Anyone with a web browser can add information about specific trees to the Urban Forest Map, such as their location, species, size, and health. That data can be used by urban foresters and city planners to better manage trees, track and combat tree pests and diseases, and plan future tree plantings. All of the values for the ecosystem services trees provide come from the Center for Urban Forest Research’s i-Tree Streets software tool.
