Hi, Welcome to OSM. In this changeset you removed trails that seems to have a good amount of heatmap activity data, are visible in Lidar data, and some parts are visible with aerial imagery not covered by tree canopy. By all accounts they seem to exist on the ground regardless of being "unauthorized".

Looks like you have a new account, so I'll give you some info on the OSM project. If a trail actually exists on the ground should not be removed from OSM, regardless if it's private or public, designated or informal/illegal/unauthorized. Please don't remove valid data from OpenStreetMap.

The other issue is you have given no source for this information, you just removed data without letting anyone know why. Also by removing the trails you left a ton of trails floating trails and trails with no ends, this is not the reality on the ground, which makes this edit incorrect and inaccurate.

The correct way to handle this is to use the tagging system. Once this is done, services that do use OSM data will reflect that and specify their access. But again you need to give a source for your information. 

Please read this for more info:

These changes have been restored. 

Going forward, you should know, purposeful removal of features known to exist on the ground is Vandalism. Only once the trails are completely gone and overgrown, then it's okay to remove it.
