A study of single-family homes in Portland, Oregon found that trees in the public right of way are associated with lower crime rates. The effect of trees on a house's lot was mixed. Lot trees small enough to block the view from a first-floor window increased crime occurrence, while larger lot trees decreased crime occurrence.
