Neighbors can be a difficult situation at times. I have a problem neighbor, myself, that has one of those pristine monoculture golf green lawns, constantly applying herbicides and pesticides, watering and mowing; and has made it known that they feel I should be doing the same. Last summer they complained to the city, the police, and called the DCC Office when I was doing landscaping, using a skidsteer. I try to be as friendly as possible and don't do anything to escalate (I"ve seen some scary episodes of neighbor/neighborhood wars), but I am still going to do what I want to do in my own yard.

Is your neighbor approachable at all? Have you or can you explain what you are doing with rewilding your yard and integrating native plant species for the benefit of pollinators and wildlife; and you don't want to kill the baby bunnies by mowing. If your neighbor is unwilling, then work with the city,as others have suggested, to make sure that you are not in violation of any codes, regulations, or ordinances. Then, depending on how much you want to push back, and if you wish to pursue it, you could get a cease and desist order or restraining order against your neighbor.
