The environmental theory posits that the location and context of the crime bring the victim of the crime and its perpetrator together.[3]
Studies in the early 2010s showed that crimes are negatively correlated to trees in urban environments; more trees in an area are congruent with lower victimization rates or violent crime rates.[4][5][6][7][8] This relationship was established by studies in 2010 in Portland, Oregon and in 2012 in Baltimore, Maryland.[4][5][7][8] Geoffrey Donovan of the United States Forest Service (USFS), one of the researchers, said, "trees, which provide a range of other benefits, could improve quality of life in Portland by reducing crime..."[5] because "We believe that large street trees can reduce crime by signaling to a potential criminal that a neighborhood is better cared for and, therefore, a criminal is more likely to be caught."[4][7] Note that the presence of large street trees especially indicated a reduction in crime, as opposed to newer, smaller trees.[4][7] In the 2012 Baltimore study, led by scientists from the University of Vermont and the United States Department of Agriculture (USDA), a "conservative spatially adjusted model indicated that a 10% increase in tree canopy was associated with a roughly 12% decrease in crime.... [and] we found that the inverse relationship continued in both contexts, but the magnitude was 40% greater for public than for private lands."[8]
