Two cars parked on Centre Street in Jamaica Plain were damaged Saturday at Harvard's Arnold Arboretum after a large section of a maple tree fell and struck them.
At about 1 p.m., the sugar maple tree, near the Centre Street gate, "lost some significant branches, likely due to wind" and hit the parked cars, said Julie Warsowe, manager of visitor education at Arnold Arboretum.
Warsowe was unsure how badly the cars were damaged, but she said one was able to pull forward, making it easier to remove the tree limbs.
"The immediate hazard has been removed," said Warsowe. "From what I understand, [the drivers] were obviously upset, but understand that it's an act of nature and not something that could have been controlled."
The owners of the vehicles are expected to submit damage claims to their insurance companies on Monday, she said.
Warsowe said she did not know the extent of damage to the tree, which was added to the arboretum's collection in 1950.
"It's unclear if [members of the horticulture staff] will just have to remove some branches or if the whole tree will have to be removed," she said.
