The U.S. Forest Service’s Pacific Southwest Research Station estimates trees lining Californian streets and boulevards provide benefits to municipalities and residents worth $1 billion. For every $1 invested in street trees, the trees returned $5.82 in benefits.
Trees lining Californian streets provide benefits worth $1 billion, a new study estimates. Among their contribution:
- Carbon storage $10.32 million
- Removing air pollutants $18.15 million
- Intercepting rainfall $41.5 million
- Energy savings $101.15 million
- Boosting property values $838.94 million
Structure, Function and Value of Street Trees in California, USA published in the June issue of Urban Forestry and Urban Greening provides analysis based on i-Tree.
The state has about 9.1 million street trees, averaging about one street tree for every four residents. But the study shows there’s room for more, another 16 million more if the resources were available. The analysis shows that even though the number of trees has increased since 1988, density has fallen nearly a third, from 105 to 75 trees/mile.
