Here, in Fairfield County, Connecticut, deer are the major threat to flourishing gardens and to highway safety. This year, K. lovingly planted blueberry bushes, raspberry bushes, Jerusalem artichokes, etc. Alas, we harvested only a pitiful bunch of each for our visiting pests chomped everything down to the stems. At least, they didn't threaten our lives, except indirectly through any ticks which may cause Lyme disease. However, we get our yard treated regulary for deer ticks so hopefully we are safe.
The bigger issue for me is that deer can cause often fatal accidents. I see them grazing on the sides of the Merrit Parkway and sometimes even by the sides of the far busier I-95. I have seen many deer carcasses on the Merrit, probably the victims of encounters with cars or pick-up trucks. I certainly hope the drivers escaped the encounter with no injuries. In the tussle between humans and deer I come down on the side of humans when it comes to highway safety.
At least, our deer are not - yet- attacking people directly, as are the monkeys in India. Here is the tragic result of one such monkey assault on a Delhi man, the deputy mayor of the city. In both cases, the solutions are the subject of much agonizing. Cull the offending animals, restrict human expansion into their domain, a little of both? The jury is still out on this issue.
