Urban Tree Survival: Trees in the Sidewalk

Boston is an old city. It has parts that go back 300 years. Certain sections of the city have been residential and had trees for centuries-. It is possible to survey longevity because the age of the streets is older than the trees. Areas have been replanted a second and third time. This study deals only with sidewalk trees. Their survival rates and average age differ from trees in parks, parkways, and back and front yards.
