An eastern cottonwood tree estimated to be more than 100 years old is being cut down from the backyard of a Rochester Street home over concerns falling branches might damage nearby properties.
The tree is more than three metres in diameter and stands about 35 metres tall. Its canopy can be seen towering above properties from several streets away.
The tree — a Carolinian poplar species with heart-shaped leaves and pointed tips — was planted around 1901 by the home's original builder and owner Michael Doherty, who was a CPR engineer, according to current owner Lynn Griffiths.http://www.cbc.ca/news/canada/ottawa/tree-rochester-ottawa-eastern-cottonwood-1.4613190
