The first GIS street tree inventory was conducted in Brookline, Massachusetts during the spring of 1994 by 97 community volunteers. The inventory program was coordinated by the University of Massachusetts Department of Forestry.
In 2009, the Parks and Open Space Division performed a complete update of all the street trees in the inventory. Approximately 11,041 trees were found along 104 miles of road. Every street tree was examined for species, health, location, diameter at breast height (DBH), dead wood, overhead utilities and management needs.
The following data was produced from the street tree inventory:
Overall Health and Condition of Street Trees
Health / Condition of Trees
Percentage of Trees
Less than 1%
Species Distribution of Street Trees
Percentage of Species Found
Over 40 different species constitute the remaining percentage trees that line Brookline's streets.
The tree inventory is an excellent management tool and is used and updated on a regular basis to ensure that all of the information remains accurate.
