Closer to where I work, over the four-year period ending one year ago, we had one tree per year fall during the Winter season. The period ended when the campus arborist did a detailed check of all the trees in the immediate area, and a number were removed. In the wider area, this part Winter had multiple trees fall. Not tree limbs, entire trees. One came down in front of a minivan carrying a local bus driver & his supervisor. I've got pictures. I'm a pedestrian: I own neither a car nor a bike. But I understand why some trees are removed. I don't think the trees here are not watered deeply enough, so they don't have a deep hold on the ground.
