I strongly suspect that to be the case. It was frustrating to put in the work picking up after our dog's bowel movements and spraying the area with a bleach solution only for other people to not pick up enough after their dogs.
Does that help?
I'm interested in any efforts to make playgrounds, dog parks, etc. safer.
Along the lines of choosing plants to reduce mosquitos.
Like perhaps there's a species of ground cover that kills parasites.
Or ticks avoid the needles from the crunchy pine tree (not a real thing, to avoid creating a false idea).
Or maybe there are fungi that break down poop faster.
Or....?
