Is the park a public park or is it on private property? If it is a public park is there a law or ordinace on the books to back it up? If it's a public spot and there's no law the sign may not mean anything.

Here in NYC buildings post signs indicating that you may not smoke within X feet of the enterance, but as long as you are on public property there is nothing they can do about it.

My college actually had the audacity to post signs on DOT street poles around the building. After I complained about vandalism of the street poles, some of them got taken down by the city, but the school put some right back up.
