In September 2011, the Stockton City Council authorized
Davey Resources Group to conduct an inventory of the trees within City Parks and
in Tree Maintenance Districts 1 and 2.
Funds for the inventory were a Prop 84 grant of $200,000 and $77,000
local contribution.
The data to be
recorded for each tree was its location (
After two years of field research, in October 2013, the Davey Tree Resources group submitted a report to the City based on their inventory entitled Urban Forest Resources Analysis.
Approximately
98,000 City trees were inventoried that consisted of about 281 different
species. The inventory included only
public trees as mentioned above and did not include trees in special districts
within newer subdivisions that have home owners associations or maintenance
districts that cover landscaping or landscape and lighting maintenance
districts. The inventory did not include trees in unincorporated areas of the
City, College or school campuses, churches, and no trees on private properties
were inventoried.
The inventoried trees have canopies that cover of 1,460 acres with 49% in good condition, 46% in fair condition, and 5% poor condition or dead.
The report detailed economic and other benefits the trees provide to the community. Values mentioned are in 2013 dollars. The 98,300 trees inventoried provide a $7,118,209 benefit to City. They reduce electric energy consumption by 11,375 megawatts annually and natural gas use by 30,200 therms. They remove 53 tons of pollutants from air and sequester 3,682 tons of CO2. They reduce stormwater runoff by 64 million gallons.
