I've been putting up signs in the park that say "Pollinator Sanctuary Do Not Mow" in a small ragged area of my mostly ignored inner city park. It's working. If there are a lot of people who really love the idea of the wildflowers being mowed someone might find out that the signs aren't real. But I can do it because I care the most about this issue, (and I want to think because I'm right about it being better for the park.)
This is how a lot of power works.
