Homeowners value trees. That much has been shown in studies performed by researchers at the U.S. Forest Service, Pacific Northwest Research Station. But now it turns out that renters value trees, as well.

A new study by Geoffrey H. Donovan and David T. Butry concluded that the presence of a lot tree raised the rental price of a single-family house by $5.62 per month, and the presence of a street tree in the public right-of-way raised the rental price by $21. The study was based on 1,000 rental homes in Portland, Ore. The study (PDF) was published in the journal Urban Forestry & Urban Greening.
