Since it is a Spring Park, I don't think it should have anything to with a weapon chain....it is park after all.
The forestry and population work well for a park. Parks usually have trees and people. Instead of highlighting the collectibles every 48 hours, I would prefer a zone buff that would affect the paper chain instead. The every 2 days buff would be reasonable for the book chain,which would could include the book binder. Individuals do go to a park to read so it would go along with the park theme.
It looks more like a Giant Stride to me rather than a Maypole to me, the "strings" are to short for a Maypole.
