I live in a deer full neighborhood in CA near San Francisco. No hunting here, it’s residential as well, and with our ongoing drought the deer have gotten VERY hungry. Eating all sorts of things they’ve never touched before. A plant by my front door that I’ve had for 20 years, Ivy, other native plants that are “deer resistant”, and it has taken all my will power not to feed them. We do have a fountain they drink from, and it is easy to imagine feeding them, and increasing the population, only to have to watch more of them be hungry. Grass usually makes up less than 10% of a deer diet. When you see them in the grass, they’re almost always looking for weeds, so they’re not forgetting to eat grass, and if people suddenly stop feeding them, they will be heartbreakingly hungry. Perhaps the Humane Society (or some other respected animal care organization) could do a neighborhood intervention and educate your neighbors? Clearly, you can’t do this as you are “on the other side”, but if they really care about the deer, they should be able to hear the same message from professionals who also care. I hope so, for the sake of the deer.
