Lots of effort recently on quantifying the financial value of ecosystem services and here's one more small piece of that: The US Forest Service has just completed an assessment of the dollar value that trees add to the urban environment and the results are pretty interesting. Surveying Chicago, Sacramento and Portland, here's what trees are worth:In Chicago, the city's 3.6 million trees reduce are pollution by 890 tons annually, saving the city $6.4 million dollars.
In Sacramento, houses with trees planted on the south and west sides reduced summertime electricity bills by $25.16 on average.
Portland houses with trees growing in front or even just near a house added an average of $8,870 to sale price and reduced the average time a house was on the market by two days.
More broadly, the survey found that when trees were grown along public rights of way, they added a combined value of $12,828 to all houses within 100 feet.
In total, the United States' 3.8 billion urban trees store $14 billion worth of carbon emissions, remove air pollution that would cost $4 billion to do otherwise.
Now, remembering that we really probably shouldn't be just reduce trees (or any part of nature) just to its human utility value, this research is really pretty cool...
