OpenStreetMap
I worked for a year as a volunteer at Goose Lake Prairie State Park near Morris, IL. I also live nearby, and am intimately familiar with the state parks up and down the Illinois River.
I notice that on OSM, especially at Goose Lake Prairie State Park that many paths are listed on the map, yet these are not shown as official trails on the park maps available at the visitor center. Since these are not trails that the park wants people hiking on is it proper to delete these from the map?

This has been discussed a few times before. OSM maps “what’s on the ground”, so it’s not wrong to map these paths; however, if access is forbidden, then the consensus is to tag them as:
