|Flowering cherry tree right under the transmission wires|
The current NSTAR policy appears to be removal of anything taller than 3 feet directly under the wires and removal of anything that is over 15 feet tall, or has the potential of growing over 15 feet tall, to the sides of the transmission wires. They need low vegetation underneath so their repair trucks have a path/adequate footing and are trying to minimize the risk of tree falls onto the wires.
The Charles River Peninsula is an unusual context because it is already largely devoid of trees. Indeed, woody growth is considered an enemy and TTOR's ecologists are constantly waging war on sumac and the like. Nevertheless there are some particular trees at risk under the current policy that I would be sad to lose. For example, the cherry tree above, which is full of birds and blossoms in early May, is directly under the wires and is definitely taller than 3 feet.
As for the Charles River Peninsula, I'm dreading what's coming down the road. I hope NSTAR will do a better job of balancing the needs for public safety and aesthetics/ecology than it has so far.
