This section contains all the help text for using i-Tree Database. For general information on i-Tree, please visit

i-Tree uses two main databases for analytical modeling: Species and Location, along with related Precipitation and Pollution databases. With global use of i-Tree, these databases will expand to include missing tree species and location-related information. i-Tree Database provides a central website for user submission of these new data. Submissions are vetted and added periodically each year so that all users can update their i-Tree Eco software and analyze these new locations and species.
