A huge silver maple is going to be cut down by the City of Vancouver, according to an article in The Columbian.
The tree, which is approximately 100 years old, stands northwest of the pavilion that is the center of activity in Esther Short Park. Charles Ray, the city's urban forester, called the decision a ‘safety issue’, noting the city has been managing the tree, but has done all it can.
From the outside, the tree appears healthy, with thick branches and green leaves, but Ray said it is rotten inside. Its decay stems from two causes: the species itself and improper care.
Maples are fast-growing, and as a result, their wood is weak and rots easily. The genetic problems were compounded by the fact that pruning was carried out incorrectly—the tree was ‘topped’ several times; that is, the top was cut off the tree.
Topping was once common, but modern foresters discourage the practice, since it harms the tree, which Forms several weakly-attached branches to take the place of the heavier one that was cut. These branches break easily, and the tree's life is shortened significantly.
The city began removing the tree May 22. Since foresters knew they would have to cut it down, they planned for the loss by planting long-living trees – including an oak, ginkgo, and elm - around it.
Events like this can become teaching tools if officials work with brochure printers to create a handout for park visitors, explaining tree management.
