Town CAO Andy Daggett said that planting a memorial tree is a nice way to remember a loved one, but there are concerns about obstructing the view.
"Over time, they become very large and basically you run out of space. And one of the things that people enjoy about the waterfront area is the vista, being able to look and see down the river, and up the river, and across and see the boats," he said.
Daggett said there are also questions about who should cover the cost of replacing damaged trees.
He encourages residents to look at other ways to pay tribute to a loved one, such as protecting a plot of property through the Nature Conservancy of Canada.
Anyone who wants to plant a tree along Montague's waterfront has always been required to apply to do so.
